How to Increase Potassium Uptake in Crops with TERRAMAR
July 2, 2026 — Posted By Agricen

When TERRAMAR is applied to a crop, one well known benefit is greater plant uptake of nutrients, including potassium (K). This not only applies to uptake of K from the soil, but also to uptake of K that is foliar applied during the season. TERRAMAR serves as a booster, getting more K into the plant when applied with foliar K products.

The greenhouse study below shows how adding TERRAMAR to a foliar K product like LoKomotive or Reax K can impact K tissue levels in the plant. There was a synergistic effect when TERRAMAR was applied with each foliar K product, leading to greater uptake of this critical nutrient than with any foliar K product alone.

Corn-Terramar-ReaxK-Lokomotive-Potassium

TERRAMAR is also a good fit with foliar K applications as well as with other in-season foliar applications a grower may be making (including herbicides and fungicides) because it is known to increase a plant's photosynthetic capacity, enhance sucrose storage and utilization, improve the crop's overall physiological functioning and mitigate the effects of abiotic stress, all of which helps build a stronger plant and preserve yield potential throughout the season.

Summary of TERRAMAR's Key Benefits:

  • Improves nutrient uptake efficiency (including K uptake)

  • Builds photosynthetic capacity resulting in a larger, more robust plant with increased sucrose storage

  • Preserves plant sucrose reserves by improving physiological functioning, leading to more sucrose availability at grain fill

  • Mitigates the impact of abiotic stresses like heat or dry conditions

Bottom line: Addressing K levels in the plant, particularly in K-limited soils, is a challenge. Making an in-season foliar K application is a solid agronomic approach that can be enhanced with the addition of TERRAMAR. Given that K is often a yield-limiting factor, utilizing TERRAMAR with a foliar K product can set the crop up for higher yield.

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.

What are the key benefits of TERRAMAR for row crops?
TERRAMAR sets a new standard in stress mitigation and plant performance. Foliar application of TERRAMAR improves abiotic stress tolerance (e.g. heat, cold, drought) at various stages of plant growth. Visible improvements in stressed crops can often be observed several days after application. Additionally, increased nutrient use efficiency has been documented when TERRAMAR is applied in conjunction with a foliar nutrition program.

How is TERRAMAR applied?
TERRAMAR is recommended for liquid foliar applications in row crops to enhance plant performance while minimizing weather-induced stress. Foliar applications deliver TERRAMAR's unique set of highly active, metabolite-based compounds for quicker absorption through the plant leaf tissue. The recommended rate for TERRAMAR is 1 quart per acre. It is compatible with a broad range of liquid fertilizers, insecticides, herbicides and fungicides for maximum application flexibility.

When should TERRAMAR be applied?
TERRAMAR can be applied in early post-emergent applications as well as mid- to late-season fungicide applications.

Should I apply TERRAMAR even if I am not anticipating severe crop stress?
Yes. TERRAMAR can optimize plant performance in all growing conditions, whether they are stressful conditions in which crop development could be impacted or average to ideal conditions in which crops have the best chance of reaching their yield potential.

How Do IBA, Kinetin & Nutrient Mobilization Impact Crop Performance?
March 6, 2017 — Posted By Agricen
Read this Q&A for a brief introduction to IBA, kinetin and other compounds that aid in plant growth and functioning—and learn how they can help optimize plant performance.

foliar

What are IBA and kinetin, and how do they benefit crops?

IBA (which stands for indolebutyric acid) and kinetin are two different types of plant growth regulators or hormones. IBA is an auxin that is produced in the plant’s leaves and shoots. IBA travels downwards to the roots and stimulates early and improved root growth, which increases plant vigor and the plant’s ability to fight off stress throughout the growing season. Kinetin is a cytokinin that travels up the plant from the root tips, directing many physiological functions of plant growth.

IBA and kinetin (as cytokinin) are the active ingredients in Radiate®, which combines these two plant growth regulators in the optimum ratio to maximize the physiological processes in the plant that drive root and shoot growth. Radiate is designed to help crops develop longer, stronger, healthier roots to improve nutrient uptake. It can be used as a foliar application during the two- to six-leaf growth period (V2-V6) to jumpstart early season root growth and plant vigor, which can lead to gains in crop productivity.

What is NutriSync® technology, and why is it important for plant health and performance?  

NutriSync® technology is based on a naturally occurring compound that transports and remobilizes nutrients to areas of peak demand within the plant. By providing better uptake and utilization of important nutrients and delivering them to the new points of growth in the plant, this technology helps to increase overall plant performance. 

NutriSync technology promotes nutrient mobilization to areas of high demand and supports better utilization of nutrients within the plant. These features create healthier plants throughout the growing season, which can lead to higher yields and a better return on investment. 

foliar-technologies-nutrisync

What synergies could I expect when using Radiate, which contains IBA and kinetin, with the technology found in NutriSync?  

As IBA and kinetin increase root growth and development, the plant’s ability to take up soil nutrients increases. After the nutrients are in the plant, NutriSync technology helps the plant move them to areas of new growth, where demand is highest. By using Radiate and NutriSync products together in the same season, growers can expect better root development, more efficient use of nutrients, stronger overall plant performance and an excellent return on investment.
