Comparison of Nutrient Content in Fescue Soils Receiving Different Fertilizer Sources.

This field experiment was designed to look at soil nutrient content following dairy manure (DM), poultry litter (PL), or inorganic fertilizer (I) application to tall fescue fields.  Establishment of the fescue was done with two different systems:  no-till (NT) and conventional tillage (CT).  Phosphorus and K concentrations were similar in all fertility treatments except the C (p<0.05).  DM and PL had the highest Zn levels (p<0.05).   Zinc concentrations were higher in NT compared to CT fields across all fertility treatments (p<0.05).   Indications from the study are that the two manure treatments resulted in higher Zn levels, but had similar contents for P & K (p<0.05).
