More Farmers Are Adopting Precision Ag

Dennis Berglund  |   November 2, 2012

a)      There is not one type of Precision Ag that is “best”

b)      Nutrient variability in apparently "uniform" fields is high

c)      We are not trying to “even out” fields with variable-rate applications

i)        We are trying to CAUSE variability, depending on the productivity of each zone



d)      The highest yielding areas are often the low testing areas and vice-versa

e)      Dry seasons cause MORE nitrogen variability

f)       Nitrogen is MORE variable after wheat, fallow and corn

g)      Nitrogen is LESS variable after soybeans and sugarbeets

h)      Phosphorus often tests lower in high yielding areas, due to higher crop removal in past years

i)        Potassium is generally lower on lighter ground, but becoming more of a problem in many areas

j)        Sulfur is deficient on most hills and sandy ground

k)      Zinc is variable in all fields and areas
