2017 New Research Article Summary Orthophosphates are 100% plant available, but a high percentage of polyphosphates in starter fertilizers convert to ortho-phosphate within just two days after application. This quick conversion from poly to orthophosphate suggests expensive “high” ortho starter fertilizers are not likely to result in increased corn yields compared to conventional polyphosphate starters….

In this short educational video, Dr. Brian Arnall with Oklahoma State University discusses the soil chemical principles behind why banding phosphorus fertilizers can result in a greater percentage of the applied phosphorus fertilizer remaining plant available.
Nitrogen fertilizer is one the most costly crop inputs following seed, and is also quite important for insuring top corn yields. In addition, nitrogen that doesn’t get taken up by a growing corn crop can cause environmental concerns. For these reasons, growers should be concerned with managing this valuable resource carefully. In this educational video… Read the full article…
Environmental Stewardship and Liqui-Grow Environmental Stewardship is essential to what we do at Liqui-Grow. We are extremely committed to helping farmers gain more crop yield per dollar spent on fertilizer while also protecting the environment. Since this is a mission at Liqui-Grow, we’ve decided to take part in the Nitrogen Grand Challenge. What is the… Read the full article…
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.

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… Read the full article…
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,… Read the full article…
Research Summary: SDS is a frequent disease of soybean, but it does not reduce yields every year—suggesting that ILeVO will be used as insurance-based management. Using ILeVO increased yields in all 7 on-farm trials in the 2016 growing season. The average yield increase across all 7 trials was 7.8 bu/ac resulting in net returns of… Read the full article…
Overview Can nitrogen models increase net revenues when compared to traditional N management rates? What about when compared to an N rate recommendation from the Corn N Rate Calculator? Several Midwestern land grant universities conducted a study to test this theory. The nitrogen management model produced the lowest net revenues. These net revenues were $21…. Read the full article…
Soil temperatures are finally approaching the mid 50’s across the state of Iowa after an unusually warm Sept. and Oct. This suggests that many more growers across the state may soon start applying fall anhydrous ammonia for the 2017 crop. After seeing the results of a 3-year study conducted by Iowa State University, I was… Read the full article…
