Further Down the Research Road… Looking at 10 Years of Research to Determine How Quickly Nutrients and Organic Matter Accumulations Occur in Monoculture Corn Production Soils.

Research plots have now been established for about 10 years to look at organic matter accumulation and nutrient content as it relates to tillage and fertilizer inputs in a corn field.  The research is a split plot design where tillage (conventional or no-till) is the primary factor and the secondary factor is fertilizer source (inorganic, 1/2 inorganic + 1/2 organic, and organic).  This presentation will look at the influence of both tillage and fertilizer on nutrient and organic matter accumulations. Initially differences were found in OM content and nutrients based on fertilizer type but not tillage (p<=0.05).
