A check-in on a corn trial near New Salem, Indiana, shows that Titan XC is adding value to the grower's standard corn program, resulting in bigger roots, plants and stalks where Titan XC-treated fertilizer was used.

“When we compared the plants we pulled, we consistently saw larger root masses, thicker stalks and larger plants on the treated side of the field compared to the untreated side," said Nutrien Ag Solutions' Sierra Gearhart, who is operating the trial.

Yellow seedlings are a familiar sight for many corn growers. On continuous corn acres, the carbon-to-nitrogen ratio can be more than double the optimal ratio* for crop residue decomposition due to the buildup of organic matter from multiple years of corn-on-corn rotations. Even if a grower has applied nitrogen during the previous fall or around spring planting, soil microbes can out-compete seedling corn plants for nitrogen when excess carbon is present. The microbes use the nitrogen as a food source, immobilizing it as they work to degrade crop residues; the seedling corn plants, meanwhile, turn yellow due to a lack of available nitrogen.

One effective way to solve the problem of yellow corn seedlings in corn-on-corn rotations is to lower soil C:N ratios by baling corn stalks for winter cow feed. Unfortunately, this is really only practical if one has cows—and most row crop farmers do not. In addition, complete removal of corn residue also takes away a significant amount of the N, P and K that comprises corn stover (Table 1).

Our final winner profile from the 2017 National Corn Growers Association (NCGA) corn yield contest features Jeannie and Wally Linneweber of Vincennes, Indiana. With a yield of 347.5 bushels per acre, Jeannie earned second place nationwide in the AA non-irrigated corn category. She and Wally used Titan XC as part of their winning program.

Today, we feature Kevin and Shawn Kalb of Dubois, Indiana, a husband and wife team who used Accomplish LM as part of their programs to win two non-irrigated categories in the 2017 National Corn Growers Association (NCGA) corn yield contest. With a yield of 386.16 bushels per acre, Kevin placed first nationwide in the AA non-irrigated corn category, while Shawn's yield of 354.13 bushels per acre put her in first place for AA no-till/strip-till non-irrigated corn. 

Results from corn trials in central Indiana show the potential for big corn yield gains and ROI with fall-applied Titan XC. 

In the fall of 2016, Titan XC-treated and untreated dry fertilizer (MES10 and 0-0-60) was applied to three fields in central Indiana using a variable rate technology (VRT) system. The fields were planted with corn in the spring. In the fall of 2017, the corn crop harvested from Titan XC-treated parts of the fields demonstrated both an increased yield and an impressive ROI compared to the crops harvested from the untreated parts of the fields. 

In both the first and second trials, the yield improvement with Titan XC was 12 bu/a compared to untreated, with an ROI of more than $35 an acre. In the third trial, the yield improvement with Titan XC was even more impressive at a whopping 41 bu/a, with an ROI of more than $135/acre.

For the past several years, Chris Perkins, a grower and Nutrien Ag Solutions location manager in Otwell, Indiana, has been running an experimental, high management, continuous corn plot using several products in the Loveland Products portfolio, including Accomplish LM and Titan, so that he can prove the value of the products he sells to his customers.

Many of the decisions that Chris makes in the management of his plot are driven by ongoing research at the university level, primarily that of Dr. Fred Below of the Crop Physiology Laboratory at the University of Illinois at Urbana-Champaign.

In this field trial on corn, root digs show a more developed root system in plants fertilized with Titan XC-impregnated dry fertilizer compared to untreated dry fertilizer. The corn trial was conducted by Nutrien Ag Solutions in New Brunswick, Indiana. 

Now that growers finally have their corn planted, many are considering adding more nitrogen to their fields. Scott Lay spoke with Hoosier Ag Today about why sidedressing supplemental nitrogen is a positive practice.

Hoosier Ag Today: Our heavy spring rains in Indiana have reduced a lot of the nitrogen that would normally be available for a corn crop this year. Scott Lay, with Loveland Products, says that sidedressing nitrogen is a practice that makes economic and agronomic sense this year.

Lay: Any time you can more closely align your nitrogen application with when the corn plant needs it, you're able to get a better result. In addition, a supplemental application of nitrogen in season is more environmentally sound, because less nitrogen is prone to loss. Given some of the weather this spring, I think it's important that we take a good, hard look at how much nitrogen is available to the growing corn plant, and then ascertain how much nitrogen may be needed.

Scott Lay recently spoke to Hoosier Ag Today about Extract PBA and how it can help maximize soybean yield potential when used with a pre-emerge herbicide or fertilizer application this spring. 

Hoosier Ag Today: Extract is a biocatalyst that helps make nutrients in the soil available to crops. Scott Lay from Loveland Products explains. 

Lay: Really what Extract does is frees up or mineralizes nutrients that are already bound in the soil. It helps to decompose residue, which is essentially nutrients awaiting to be utilized by the plant. It simply accelerates that process that Mother Nature is already performing, by helping to decompose and mineralize more nutrients, putting them in a plant available form so that we can maximize yield in a given crop.

In this trial from Attica, Indiana, Extract PBA brought in big returns on two crops in the same year.

Extract PBA was applied in the fall of 2015 on soybean stubble, and winter wheat was planted. At harvest, the crop planted where Extract was applied had an 8 bushel per acre yield advantage.

In 2016, the grower planted double crop soybeans in the same field, again gaining a yield advantage (5 bushels per acre) where Extract PBA had been applied the previous year. The combined ROI to the grower was $69/acre.
