Technical Abstract: Fertigation of dairy waste is being evaluated as a method of manure utilization and crop production within a high-yield, intensive agricultural system. Among several environmental and economic parameters measured, crop yield, nutrient removal and use efficiency associated with both manure and fertilizer application are being evaluated in two year round forage production systems in both a center-pivot and in small plots. For the pivot, during year 1 a rye-corn-corn system produced 26% more dry matter than a rye-corn-brmuda system, and manure produced 29% more dry matter than fertilizer. During year 2 the rye-corn-corn system produced 47% more dry matter than rye-corn-bermuda and manure produced 8% more than fertilizer. In the small plots, rye-corn-corn produced 16% more than rye-corn-bermuda and manure produced 37% more than fertilizer. During year 2 the rye-corn- corn produced 14% more dry matter than rye-corn-bermuda.
