High Rate Fertilizer P to Correct Very Low P Zones on Variable Rate Fields – The objective is to demonstrate the yield and economic benefits of one-time application of high rates of fertilizer P to correct zones that test very low for available P on fields where variable rate nitrogen fertilizer is practiced.
Variable Rate Fertilizer N (10 field sites) – The objective is to evaluate the agronomic and economic benefits of varying fertilizer N application rates based on soil conditions and crop yield potential.
U of S Sulfur Availability (2 sites) – The objective is to evaluate the rate of conversion of elemental sulfur into plant available sulfate from enhanced release sulfur fertilizer products.
Hog Manure as a Supply of Nutrients – The objective is to evaluate the effect of hog manure on crop yield and soil fertility.
Rapid Release Elemental S for Canola – The objective is to evaluate the yield impact of a new rapid release elemental sulfur fertilizer product for canola.
Rapid Release Elemental S for Cereals – The objective is to evaluate the yield impact of a new rapid release elemental sulfur fertilizer product for cereals.
Vitasul (Elemental S) for Wheat – The objective is to evaluate the yield impact of a new rapid release elemental sulfur fertilizer product for wheat.
Alternate S Products – The objective is to evaluate the response of canola to different N and S rates, sources and placement including a new homogenous, multiple nutrient project, Amidas.
Copper Fertilization of Forages – The objective is to determine whether forages grasses will respond to foliar copper fertilizers on soils that appear copper deficient.
