Are You Using a Nitrogen Stabilizer That Works?

Hello Everyone and over the next few weeks we are going to be sharing research from Top End Farming from two years of research at their farm in Northern Illinois.  They studied tons of different products and had dozens and dozens of replications with a big emphasis on micro-nutrients. 2018 was a year full of changes and weather challenges but it was a great learning experience. Dan from Top End Farming used a 4 row plot planter. They experienced heavy rains all year which challenged everything from emergence to making timely spray passes. Having wet feet all year certainly knocked a lot of the Top End yield potential out, but it also provided a great learning opportunity for us all.  The studies on starter formulations were eye opening and so were the nitrogen studies. More N isn’t always the answer to yellow corn. 😉

Dan pulled soil tests in the fall of 2017 to see what was needed and at what rates. Nitrogen was sprayed on behind the planter at a rate of 60gal of 32% unless otherwise noted. Mid-season the entire plot was Y-dropped with 10gal. 32% and 5gal. of ATS.

While Dan strives to maintain this as an independent plot, we are indeed distributors with Conklin and we firmly believe you will not find a higher quality product anywhere. Conklin also provides top end knowledge sharing.

Everything we do is based off of specific soil tests, field by field.  So, we’re not throwing blind darts at the wall wasting ANY money. This is why we highly recommend everyone uses MidWest Labs from Omaha, NE to run independent soil tests. We look forward to sharing results with you over the next few weeks!

First up, the Nitrogen study.  It was conducted using three different rates of 32% and two different stabilizers. 40, 50, and 60 gallon rates were used stand alone and with Instinct and Guardian.

Instinct has an active ingredient of nitrapyrin.  It is a popular stabilizer but comes with a down side of causing corrosion and destroying soil bacteria.

Guardian has an active ingredient of dicyandiamide.  It is non-corrosive to your equipment and doesn’t kill valuable soil bacteria.

Guardian

  • Plot #34: 40 gallon 32%UAN and 1.5qt Guardian yielded 217.34bpa
  • Plot #35: 40gallon 32%UAN and 24oz. of Instinct yielded 212.65bpa

Guardian out yielded competitor by 4.69 BPA

  • Plot #36: 40 Gallon 32%UAN yielded 213bpa
  • Plot #37: 50 Gallon 32%UAN yielded 208.12bpa

Guardian out yielded competitor by 4.88 BPA

  • Plot #38: 50 Gallon 32%UAN and 24oz. of Instinct yielded 235.01bpa
  • Plot #39: 50 Gallon 32%UAN and 1.5qt Guardian yielded 279.72bpa

Guardian out yielded competitor by 44.71 BPA

  • Plot #40: 60 Gallon 32%UAN and 1.5qt of Guardian yielded 276.28bpa
  • Plot #41: 60 Gallon 32%UAN and 24oz. of Instinct yielded 265.43bpa
  • Plot #42: 60 Gallon 32%UAN yielded 250.27bpa

Guardian out yielded competitor by 10.85

Cost of both stabilizers is $9/acre

Please note: at the beginning of the 2018 season Dan approached several other local retailers in his area and offered his soil test and some strips in the plot to see how their products would compare they all admittedly refused to take part and therefore the few competitive products in the trials were obtained from their customers.
