Do you have enough?
Over the past few months, producers have purchased a large portion of their fertilizer needs; however, it may not be enough.

Did you know that 2015 is the “International Year of the Soil”? The United Nations made this declaration on December 5th, 2014, which was the first ever World Soil Day. The UN pointed out that by the year 2050, the amount of food producing land available per person will be a quarter of what it…
Nitrogen uptake in corn – Are patterns changing and how do we manage?
As corn varieties have developed over time, so has the amount and timing of nitrogen uptake in corn. In research done by Tony Vyn, Professor of Agronomy, Purdue University, “modern hybrids (post-1990) took up 27 percent more total nitrogen from the soil after flowering than pre-1990 corn plants. In fact, nitrogen uptake after flowering in…
Do you know how to calculate nutrient removal?
Who can tell me how much phosphorus (P2O5) and potassium (K2O) was removed by crops over the last three growing seasons? This question was posed to the audience at the SouthWest Ag Conference by Peter Johnson with little response. Fertilizer is a large production expense and the ability to monitor its use is becoming more…
