TERRAMAR Enhances Corn and Soybean Fungicide Applications
September 17, 2025 — Posted By Agricen

Corn and soybean fungicide applications are crucial tools that help growers minimize loss from yield-robbing diseases like tar spot and southern rust. In the same pass, growers can also enhance nutrient uptake and plant tolerance to abiotic stresses, such as heat, by adding TERRAMAR to the tank mix.

In a recent corn trial conducted in Sullivan County, Indiana, a grower split an 80-acre field, treating half the field with his normal fungicide (Veltyma) at the VT growth stage and the other half with the same fungicide treatment plus 1 quart per acre of TERRAMAR.

At harvest, there was a clear difference between the two halves of the field. On the TERRAMAR-treated half, the plants looked overall healthier compared to the plants on the untreated half. The grower also reported that they stood better and didn't lean as much after the fields experienced some strong winds. At harvest, the half treated with TERRAMAR had a +12 bu/acre yield advantage and was 1.5 points drier compared to the untreated half.

Casey Holder, Location Manager of Nutrien Ag Solutions in Shelburn, Indiana, served as a crop consultant on the trial. "To think, he gained that much yield and profit on top of the corn being drier which saved him money at the bins...it was a huge success," he says. "Now we treat almost every acre of corn and beans with TERRAMAR. Most of my customers apply a quart during their post herbicide pass as well as another quart at fungicide timing."

Similar results have been seen in soybeans when TERRAMAR is applied with a fungicide, such as in this trial from Oakland City, Indiana, showing a yield improvement of +12 bu/acre when TERRAMAR was added to the grower's standard soybean fungicide application. 

Terramar-fungicide-soybeans-IN

There are several reasons why TERRAMAR complements a fungicide application so well. First, TERRAMAR has been shown to increase photosynthesis and nutrient uptake. It also increases sucrose production, which typically leads to a yield increase. In addition, TERRAMAR increases transpiration and decreases the crop canopy temperature, helping the crop to better tolerate stresses caused by heat and dry conditions, which can be common in summer when fungicide applications go out.

[Interview] Keeping Crops on Track to Preserve Yield Potential
June 23, 2025 — Posted By Agricen

Wity-radio-down-on-farmAgricen’s Scott Lay recently sat with Dennis Michelsen of WITY Radio to discuss using TERRAMAR to keep corn and soybean crops on track and help protect them against yield loss.

Dennis - WITY Radio: One thing that we can count on is that we're going to have some very stressful days with our crops. It doesn't matter whether you're talking corn or soybeans, weather events put a lot of stress on the plants.

Scott - Agricen: As farmers look at their fields, regardless of zip code, any extended period of cooler temperatures like the northern half of the United States experienced this past May translates into slower developing crops, more stagnant growth and stresses that could impede the yield potential that those corn and soybean fields have. While we cannot change the weather, we can choose practices to help minimize its impact and deliver a more consistent result from year to year. That's a lot of the story behind what TERRAMAR delivers for crops.

Dennis - WITY Radio: Tell us a little bit about what TERRAMAR does for row crops.

Scott - Agricen: This will be the third year we've had TERRAMAR in row crops, and we’ve been getting a lot of positive yield responses and consistency from it.

What TERRAMAR delivers boils down to two things. First, it helps minimize the impact of weather stresses like cold or heat stress. It does this by helping the plant increase photosynthesis and water transpiration to make that plant more resilient. The second part to TERRAMAR is the carbon-based component that provides fuel for the plant to allow it to uptake more nutrients. This also translates to increased sucrose levels at reproductive stages. Sucrose is a fuel source or reservoir to supply starches and sugars to the forming grain, and that's what ultimately leads to a yield advantage.

Dennis - WITY Radio: With the cold temperatures we had in May, are we going to be looking at root growth that wasn't as vigorous as usual?

Scott - Agricen: That's often the case. And again, we can't control the weather, but if we have the ability to get that plant back on track and get it performing more normally from a physiological point of view, we have a better chance of preserving yield potential and delivering a positive yield result when combines roll through the fields this fall.

Dennis - WITY Radio: How and when do you apply TERRAMAR?

Scott - Agricen: You can apply TERRAMAR anytime after the crop is emerged. At this time of year, it's really applied in concert with post-emerge foliar herbicides. As we progress later into the growing season through the reproductive stages in corn and soybeans, it can be applied with fungicides. It simply aligns with the practices that growers are already utilizing to maximize yield.

Dennis - WITY Radio: You’ve done many different test plots in various crops, and have seen repeatable results with TERRAMAR.

Scott - Agricen: If you're going to employ a new technology, it has to provide a consistent return on investment, particularly in the face of the commodity prices we have today. In nearly 200 yield observations, we’ve seen a positive net return on investment 85% of the time, meaning the yield return was greater than the cost of the product. On average, we see about a +4.7-bushel yield advantage in soybeans and nearly a +9-bushel yield advantage in corn. Again, that’s a positive win rate 85% of the time, meaning positive ROI. That's something you can take to the bank.

Dennis - WITY Radio: Even when it's just breaking even, this is an insurance policy to make sure that you're not losing more yield.

Scott - Agricen: It is. And again, the day you plant the crop is the greatest potential for yield that exists. The name of the game from there on after is simply preserving the yield potential that is there. If you can ensure more nutrients flowing into that plant, if you can take a bite out of the heat stress that presents itself through June and July, you've got a better chance of maintaining yield potential. As we’ve seen in hundreds of instances, that translates to a very consistent return on investment, which gives folks confidence in applying TERRAMAR.

TERRAMAR is available from Nutrien Ag Solutions.

TERRAMAR & RADIATE Can Help Keep Crops on Track After Cool Conditions
June 5, 2025 — Posted By Agricen

Terramar-Radiate_Cool_ConditionsThis spring, many growing areas of the United States are coming off an extended period of cooler-than-normal temperatures. This makes it an ideal time for post applications of TERRAMAR and RADIATE to get the crop back on track. 

Cooler conditions slow plant photosynthesis and physiological functions, which leads to slower crop growth and development. TERRAMAR helps in this scenario because it increases the rate of photosynthesis, chlorophyll production and water transpiration, leading to increased nutrient levels in the plant. RADIATE is also useful here, since RADIATE enhances root development, increasing the plant's ability to access nutrients and moisture.


TERRAMAR: Learnings from Advanced Agrilytics' Corn Trials

During the 2024 season, Advanced Agrilytics evaluated TERRAMAR on ten farms across Iowa, Illinois, Indiana and Ohio to look at nutrient uptake and crop performance metrics. On all farms, TERRAMAR was foliar-applied on V6 corn at a rate of 1 quart/acre and compared to the grower's standard practice alone (no TERRAMAR treatment).

What were some of the key findings?

  • TERRAMAR increased nutrient levels in the treated corn plants. With a foliar application of TERRAMAR, crop uptake of both nitrogen and phosphorus was increased compared to the untreated plants. At R1, nitrogen was increased in over 50% of samples compared to the controls, while phosphorus was increased in nearly 80% of the samples. Higher levels of total plant nitrogen and phosphorus are indications of TERRAMAR’s ability to make nutrients more available to the plant and convert the starches, sugar and carbohydrates needed for yield.

  • TERRAMAR increased sucrose concentration in the treated corn plants. Sucrose levels in the plant at R1 are the most reliable predictor of yield capacity. Sucrose in the stalk is essentially the fuel reserve that the plant has to draw from to fill kernels. A V6 application of TERRAMAR led to increased R1 sucrose levels in 75% of the samples compared to the controls. Further, when there was a PRE application of EXTRACT followed by TERRAMAR, sucrose was increased 100% of the time.

  • TERRAMAR provided yield benefits in both water-limited and stable environments. The greatest yield advantage (69% positive outcomes) was seen in water-limited environments.

Win Rate 2024 Terramar Trials Advanced Agrilytics
You can hear more about the trial findings by watching a recap of this webinar, during which AJ Woodyard, agronomy lead for Ag Ingenuity Partners (the independent research arm of Advanced Agrilytics), provides trial details.


A Note on Soybeans

In soybeans, there has been minimal plant growth in the last two to three weeks due to cooler conditions. TERRAMAR can be applied to soybeans to increase the uptake of a broad range of nutrients, including potassium, which is vital for starch and protein formation and can help regulate the stomata as temperatures increase in June. By applying TERRAMAR to their crop, soybean growers have the opportunity to boost plant development for quicker row closure and create more plant mass to support the upcoming reproductive stage.

[Watch] Preserving Yield Potential with Proactive Foliar Applications
May 27, 2025 — Posted By Agricen

05-25-foliar-webinar-landing-pgHow do in-season foliar applications help crops achieve or preserve their yield potential? 

Watch our on-demand webinar, "Preserving Yield Potential with Proactive Foliar Applications," to learn:

  • How foliar applications help growers preserve yield potential
  • How foliar-applied TERRAMAR increases nutrient uptake and minimizes the potential impact of weather-related stress in a broad range of crops
  • Details from Advanced Agrilytics' on-farm trials testing early post applications of TERRAMAR on corn

Guest speaker AJ Woodyard, the research agronomy lead for Ag Ingenuity Partners (the independent research arm of Advanced Agrilytics), presents some of the key findings from TERRAMAR corn trials conducted by Advanced Agrilytics during the 2024 season. Key takeaways from the trials, in which a V6 foliar application of TERRAMAR was evaluated on ten farms across Iowa, Illinois, Indiana and Ohio and compared to a control, include increased crop uptake of nitrogen and phosphorus, increased sucrose concentration in the plant and yield benefits in both water-limited and stable environments where TERRAMAR was applied.

A combination of two unique technologies, TERRAMAR delivers increased nutrient uptake and enhanced stress mitigation, which can optimize plant health and contribute to enhanced yield. The carbon-based technology (CBT) in TERRAMAR, which is derived from biologically converted leonardite, enhances nutrient uptake and photosynthetic capacity, providing key carbon derivatives for additional energy to optimize plant performance. This is complemented by TERRAMAR's marine-based technology (MBT), a formulation of biologically extracted kelp, which improves crop tolerance to abiotic stresses such as heat, cold, dry conditions and salt.

Multiple field trials validate the effectiveness of TERRAMAR as an in-season addition to foliar nutritional or crop protection programs in a wide variety of crops, including corn, soybeans, wheat, grain sorghum, cotton, alfalfa, lettuce, onions, potatoes and sugarcane.

TERRAMAR is available from Loveland Products through Nutrien Ag Solutions.

[Interview] Protecting Existing Crop Yield Potential from Heat Stress
July 31, 2024 — Posted By Agricen

Wity-radio-down-on-farmAs we progress through the reproductive stage of the growing season, many growers have reason for optimism in terms of yield. But, even for those who are having a good year so far, stress from excess heat can have a negative impact on the crop. Agricen’s Scott Lay sat with Dennis Michelsen of WITY Radio to discuss how TERRAMAR can be applied with fungicide to help protect existing yield potential from heat and other weather-related stress.

Dennis - WITY Radio: It’s been a weird year with the weather. I believe all of those different weather factors are adding to crop stress, and we've already had a prolonged period of hot nights.

Scott - Agricen: In the summer months, heat will happen in every zip code, in every crop. It's a matter of trying to protect the yield potential that exists. With TERRAMAR, we have a technology that can help minimize the impact of heat stress on a crop. It’s a good day for a crop if you can minimize the temperature within the crop canopy. What we're seeing in a number of replicated trials is that we can reduce the crop canopy temperature by two to four degrees Fahrenheit with TERRAMAR.

Dennis - WITY Radio: We know we're going to get more heat going forward. How much benefit is there to applying TERRAMAR with fungicides?

Scott - Agricen: Let's review the negative detriments of heat on a crop. We know it impacts the ability of that plant to photosynthesize and to transpire water, and we know that it affects the plant's ability to mobilize nutrients into the plant and fill grain. So, if we can minimize that canopy temperature by two to four degrees with TERRAMAR, that's a positive. Secondarily, if we can increase the amount of nutrient uptake or movement in that plant, that's also a positive. We have documented a nutrient increase in tissue samples in the range of 10 to 15% with TERRAMAR.

Dennis - WITY Radio: Does that translate to yield?

Scott - Agricen: More often than not, it does. But more importantly, at each stage of the game, including the reproductive stage where we are today, we're attempting to increase the amount of nutrients available for that plant—to move starches and sugars to form that grain. If we can do that, we have a better opportunity to yield.

Dennis - WITY Radio: If you look at our weather this year, we had a lot of different weather conditions – from really wet to really dry, and with wind and hail damage in some parts. Now we take that already stressed-out corn, and we add more heat. Is there a cumulative effect of stress on a plant?

Scott - Agricen: I think there is a compounding effect. As we reach the critical reproductive stage, whether it be in corn, soybeans or perhaps other crops, fungicides are often applied to minimize the impact of disease, and that's a step in the right direction. But for factors brought about by the weather, TERRAMAR, in concert with a fungicide, provides a synergistic effect. If we can minimize the impact of a disease like tar spot, gray leaf spot or northern corn leaf blight with a fungicide, while also minimizing the canopy temperature of the crop with TERRAMAR to increase photosynthesis and nutrient uptake, the cumulative effect is positive. We're attempting to preserve yield potential, and we believe that's our best opportunity to do so.

Dennis - WITY Radio: With grain prices where they are, a producer I spoke to recently said he is changing his strategy this year to ensure he can get every additional bushel, because he needs that to make money this year.

Scott - Agricen: Corn and soybean commodity prices are not what they were a year ago, and certainly not what we would like them to be. The only other lever that can be pulled to impact net farm income is the yield. Again, we're not going to increase yield at this point. We're simply trying to preserve what yield potential exists. So if the crop is worth investing in to preserve yield potential, fungicide plus TERRAMAR gives a very consistent payback in terms of return on investment.

Enhancing Wheat Performance on Your Farm with TERRAMAR
June 10, 2024 — Posted By Agricen

Wheat growers commonly apply fungicides to their crops to optimize plant health and yield. Typical application timings include early April after the flag leaves emerge (Feekes growth stage 9) and at heading shortly after (head scab application/Feekes growth stage 10.5.1). TERRAMAR can be utilized in the same pass as a wheat fungicide during any application timing, offering another stress-fighting and yield-enhancing tool to optimize crop yield potential.

What benefits can TERRAMAR add to a wheat fungicide application?

  • TERRAMAR minimizes the impact of weather-related stresses (e.g., cold and dry conditions) to help maintain normal physiological functions. 

  • TERRAMAR increases nutrient uptake and photosynthetic capacity at a critical time of yield determination.

Nutrien Ag Solutions has conducted multiple field trials in which TERRAMAR was applied at different stages of wheat growth with a fungicide. As seen in the examples below, consistent yield responses and a positive return on investment (ROI)* were observed across the different timings, whether one or multiple applications of TERRAMAR were made with the grower’s standard practice (GSP). 

FLAG LEAF/FEEKES 9 FUNGICIDE APPLICATION

05-24 Terramar-Wheat-Feekes 9

In a Wisconsin field trial, TERRAMAR was applied at 1 quart/acre with fungicide at the Feekes 9 growth stage (flag leaf). The addition of TERRAMAR to the grower's standard wheat fungicide program led to a +3.62 bu/a yield advantage compared to the fungicide alone, with an ROI of 2:1.

(If a flag leaf fungicide application is not being made, TERRAMAR is also compatible with herbicide applications made at Feekes 8.)

HEAD SCAB SPRAY/FEEKES 10.5.1 FUNGICIDE APPLICATION

05-24-Terramar-Wheat-head scab 2 plots

In a field trial in Michigan, adding TERRAMAR to the grower's head scab fungicide application led to a yield advantage that ranged from +3/9 bu/a (Plot 1, ROI of 2:1) to +12.8 bu/a (Plot 2, ROI of 7:1).

05-24-Terramar-Wheat-Head Scab Spray IN

In an Indiana trial, the yield advantage when TERRAMAR was applied with a wheat head scab fungicide was +9.41 bu/a, with an ROI of 5:1 compared to the fungicide alone. 

05-24-Terramar-Wheat-Head Scab Spray OH

In Ohio, a yield advantage of +12.0 bu/a was seen when TERRAMAR was added to a wheat head scab fungicide application, with an ROI of 7:1 compared to the fungicide alone. 

FEEKES 8, 9 & 10.5.1 (3 APPLICATIONS)

05-24-Terramar-Wheat-3 Apps-PA

Lastly, a Pennsylvania field trial in wheat showed an +18.0 bu/a yield advantage when TERRAMAR was applied at 1 pint/acre at three time points: First with herbicide at Feekes 8, and then with fungicides at Feekes 9 (flag leaf) and Feekes 10.5.1 (head scab spray). The ROI in this trial was 9:1.

SUMMARY

Whether applied to wheat or another row crop, a foliar application of TERRAMAR offers a flexible and cost-effective way to enhance plant health and improve yield.

*ROI calculations assume wheat at $6/bushel.

[Corn Trial] Lower Canopy Temperatures & Greater Nutrient Uptake with TERRAMAR
May 20, 2024 — Posted By Agricen

By Jeremiah Butler, Agricen

Early in the summer of 2023, widespread nutrient deficiencies were observed in the Corn Belt, particularly potassium (K) deficiency in corn. Due in large part to drier-than-average early season growing conditions, abiotic stress—or stress from environmental conditions—was more prevalent, impacting crop physiological development and reducing nutrient uptake during a critical phase.

Beginning in mid-June, a number of crop consultants were reporting an interesting phenomenon. Corn fields treated with a foliar application of TERRAMAR in the V3-V7 growth stage visually appeared to be healthier and were not exhibiting the same level of K deficiency symptoms as untreated corn.

As a result of these observations, trials were conducted on later-planted corn in Minnesota and Michigan, and on a soybean field in Indiana to evaluate the impact of a V4 application of TERRAMAR on nutrient uptake and abiotic stress reduction. Corn nutrient demand significantly increases after the V4 window to produce a healthy, high-yielding crop.

In the Minnesota trial, a foliar application of TERRAMAR (1 quart/acre) was made at V4, followed by rigorous tissue sampling to determine nutrient uptake levels of treated versus untreated plants. A total of 135 tissue samples were taken at the V9 growth stage (10 days after application) hourly over a 12-hour period (7 am to 7 pm). In addition, leaf surface temperature readings of treated and untreated plants were taken to evaluate canopy temperatures. Higher ambient air temperatures during the trial period were an indication that the corn crop was experiencing moderate heat stress.

Compared to the untreated corn, TERRAMAR increased the uptake of the majority of nutrients into the corn leaf tissue (Fig. 1). Potassium uptake was particularly notable, showing a 38% increase compared to the untreated corn.Terramar-tissue-samples-1200px

Fig. 1. Percent increase in micro- and macronutrients in corn tissue with TERRAMAR treatment versus untreated. Samples taken 10 days after foliar application of TERRAMAR.

Leaf canopy temperature was also notably reduced in corn that had been sprayed with TERRAMAR compared to the untreated corn (Fig. 2). Lower leaf temperatures indicate that the plants were under less stress and were therefore able to more efficiently perform physiologic functions such as transpiration and photosynthesis.

Terramar-tissue-temp-1200pxFig. 2. Tissue temperature in the leaf canopy of corn plants treated with TERRAMAR versus untreated. Temperatures taken using thermal camera 10 days after foliar application of TERRAMAR.

At harvest, the TERRAMAR treatment was associated with a yield advantage of +11.2 bushels/acre compared to the untreated corn (165.8 bu/a vs 154.6 bu/a, respectively).

These results are in line with prior research demonstrating TERRAMAR’s consistency in reducing stress from abiotic factors (e.g., heat, drought, salinity, wind, hail and wet environments) at any given time in the growing season following a foliar application.

While stress mitigation significantly contributes to the product’s performance, more recent research indicates that a foliar application of TERRAMAR also increases nutrient uptake (documented by leaf tissue tests in both stressed and non-stressed environments), nitrate assimilation, carbon fixation, and photosynthetic capacity. These benefits add value by providing more efficient nutrient uptake during the crop’s critical demand windows.

Every growing season creates a different set of challenges, but some things remain constant. Globally, 50% to 70% of crop yield is lost to abiotic stress factors. Taking measures to reduce the impact of abiotic stress and increase nutrient uptake throughout the growing season with new technologies like TERRAMAR provides growers a fighting chance to add more to their bottom line across a range of crops.

[Interview] Addressing Weather-Induced Crop Stress
May 13, 2024 — Posted By Agricen

Wity-radio-down on farmAs growers finish putting this year’s crop in the ground, Agricen’s Scott Lay spoke with WITY Radio’s Dennis Michelsen about TERRAMAR, a foliar product designed to help crops increase nutrient uptake and better tolerate weather-induced stress.

Dennis - WITY Radio: It’s impossible to predict the weather long term, but we know that something will always put our crop under stress every growing season. Would it be fair to say that the main reason a producer would want to add TERRAMAR to their lineup is to reduce stress?

Scott - Agricen: That is the essence of it. Weather-induced stress is one of the greatest yield robbers that farmers face. Up until this point, short of going to church on Sunday and praying for more moderate temperatures and rain, there's not been a heck of a lot we could do to address stress.

TERRAMAR was new to the row crop market last year, during which nearly 2M acres were treated. It does two things. One, it has a biologically extracted kelp component that minimizes the effects of weather-related stress, such as heat, drought or early season cold. Secondly, it has a biologically extracted carbon component that stimulates the plant to pull in more nutrients to aid in chlorophyll production and photosynthetic capacity, as well as increase carbon fixation in the plant. In this way, TERRAMAR provides a one-two punch that equals a better chance for yield at harvest time.

Dennis - WITY Radio: How and when is this product applied?

Scott - Agricen: TERRAMAR is designed for post-emergent foliar application throughout the growing season. It can go out early in the vegetative stages with a post-emergent herbicide in advance of the stresses that will present themselves to the crop. Then, as we get into the reproductive stages where a fungicide is often applied for the purpose of minimizing the impact of disease, a dose of TERRAMAR at that time will carry on for at least two to four weeks to minimize the impact of weather-induced stress.

We can measure this by canopy temperature. Last year, we did a number of trials across Indiana, Michigan and Minnesota to quantify the impact of TERRAMAR on canopy temperature in both corn and soybeans. Throughout the course of a July day, we saw that the canopy temperature of plants treated with TERRAMAR was 3°F to 5°F lower compared to untreated.

If you can lower the canopy temperature, that plant will be more efficient in reproducing and filling.

Dennis - WITY Radio: That's the key, Scott, because we always think about drought as a big stressor of crops, but we also get those hot nights where the temperature doesn't drop much below 75°F. That plant needs all the help it can get to stay out of stress, or we're losing bushels.

Scott - Agricen: That is absolutely correct. Heat happens in every zip code and every crop, every year. If we can moderate the temperature of the canopy, we're minimizing the impact of heat. It's not a replacement for a 60° F night. But if we can minimize the impact of those warm July and August evenings and give that plant a better chance to photosynthesize and to transpire water and nutrients, again that correlates very nicely to better yield potential.

Dennis - WITY Radio: What's the ROI that we can expect?

Scott - Agricen: In third-party university trials and farmer-conducted side by sides, we’ve found that the average response is 7 to 10 bushels in corn, 4 to 7 bushels in soybeans and 5 to 8 bushels in wheat. All told, regardless of crop, the average is a 3 or 4:1 return on investment. So for every dollar invested in TERRAMAR, a farmer could expect a $3 to $4 return as a result of an increased yield result.

TERRAMAR is available from Nutrien Ag Solutions.

[On-Demand Ag Webinar] Stand Up to Stress for Higher Yield & ROI
April 24, 2024 — Posted By Agricen

CropLife-webinar-archive

Whether conditions are “ideal” or stressful, the key is to be prepared for whatever the growing season brings so that you can reach your yield goals.

In this on-demand webinar hosted by CropLife, "Stand Up to Stress for Higher Yield & ROI," you'll learn:

  • What abiotic stress is

  • How ag biologicals and biostimulants fit into crop stress and plant health management programs

  • How TERRAMAR, a new foliar technology for agricultural crops, enhances plant performance while mitigating the impacts of abiotic stress

During the webinar, Dr. Connor Sible of the University of Illinois discusses common abiotic stresses, how biological and biostimulant technologies can play a role in addressing them, and, specifically, how marine extracts promote stress relief in plants. He also discusses the need for a proactive approach when it comes to application timing.

"Stress mitigating biostimulant applications need to be proactive, not reactive," says Dr. Sible. "The crop needs time to build the defense so that it is able to tolerate the stress when it arrives."

Agricen's Dr. Brian Cornelious follows his presentation with a discussion of TERRAMAR, which can be used to enhance nutrient uptake while improving crop tolerance to abiotic stress.

TERRAMAR is a unique combination of carbon- and marine-based components that have complimentary functions:

  • Carbon-Based Technology (derived from biologically converted leonardite) enhances nutrient uptake and provides key carbon derivatives for additional energy to optimize plant performance

  • Marine-Based Technology (derived from biologically digested kelp) improves crop tolerance to abiotic stressors such as heat, drought, salt, and cold

Exclusively available from Loveland Products through Nutrien Ag Solutions, TERRAMAR can be used in combination with early, mid-season, or late-season foliar applications (including foliar nutrition, insecticides, herbicides, and fungicides) to mitigate stress and improve nutrient uptake. Foliar applications deliver its unique set of highly active, metabolite-based compounds for quick absorption through the leaf tissue of the plant. Multiple field trials validate the effectiveness of TERRAMAR as an addition to crop protection and nutritional programs.

Watch the webinar to learn how to help your crops stand up to stress for higher yield and ROI.
