The Nitrogen Grand Challenge

Environmental Stewardship and Liqui-Grow Environmental Stewardship is essential to what we do at Liqui-Grow. Because of our commitment to helping protect the environment—and to helping farmers gain more crop yield per fertilizer dollar spent—we have decided to take part in a Nitrogen Grand Challenge. What is the Nitrogen Grand Challenge? The Nitrogen Grand Challenge is…

Fertilizer Placement to Improve Crop Nutrient Acquisition and Yield

Summary Fertilizer placement in soil improves plant nutrient-acquisition. Many fertilizer placement techniques have been developed. Fertilizer placement leads to higher yield than broadcast. Fertilizer placement leads to higher plant nutrient-content than broadcast. NH4+ + P or Urea + P placed at 10–20 cm soil depth shows best plant growth effects.

New Research Comparing Ortho/Poly-Phosphate Ratios for In-Furrow Seed Safe Starter Fertilizers

Article Summary Ortho-phosphates are 100% plant available, but a high percentage of poly-phosphates in starter fertilizers convert to ortho-phosphate within just two days of application. This quick conversion from poly- to ortho-phosphate suggests expensive “high” ortho starter fertilizers are not likely to result in increased corn yields compared to seed-safe fluid starters containing a higher…

Doctor in the Field

There’s a new doctor in the field. And by “field” we mean the corn field. For the last two and a half years, Liqui-Grow’s Lead Agronomist, Jake Vossenkemper, has been working on his dissertation in Crop Sciences at the University of Illinois. Jake has been a PhD student since the spring of 2012. On Monday,…

Corn N Rec’s Using Nitrogen Management Models – Are they “Big League” Ready?

Within the last few years nitrogen management models seem to be all the rage. DuPont Pioneer is promoting Encira Yield Nitrogen, Monsanto has Climate-N and Agronomic Technology offers Adapt-N. This is a short list of the big 3, but don’t forget about the droves of Silicon Valley start-ups promising to solve all our nitrogen management woes. The idea behind these N models is stellar, use less fertilizer N in years with low nitrogen loss conditions and more fertilizer N in years when more N loss has occurred. Doing so would potentially reduce N pollution, save on fertilizer N costs or increase yields in years when more fertilizer nitrogen is required. This is, of course, the utopia for which the agricultural industry has been searching….

Highlights from the 2015 Walcott Research Farm

The 2015 growing season at the Walcott research farm was wetter and cooler than normal. June and July were particularly wet, with about 14.5 inches of precipitation falling in these two months alone.  The wet weather caused periodic ponding and nitrogen loss which was noticeable in the corn, particularly in the lowest laying parts of…
