However, much of the P and K can be recovered by runoff control systems such as settling basins and holding ponds. The greatest nutrient response follows land application and immediate incorporation into the soil. Plow down solid manure as soon as possible to minimize nitrogen loss and to begin release of nutrients for plant use. Most losses occur in the first 24 hours after application, so incorporate manure into the soil as soon as possible. Nitrogen loss as ammonia from land is greater during dry, warm, windy days than during humid or cold days.
Ammonia loss is generally greater during the spring and summer months.
Uniform application of manure prevents local concentrations of ammonium or inorganic salts that can reduce seed germination and yields. Before heavy manure applications, have your soil tested for fertilizer needs and nutrient imbalance. Adjust waste application rates for your soil conditions against soil tests for nitrogen, phosphorus, and potassium. Total N is mostly organic and ammonium nitrogen. N. Ammonium N is equivalent to commercial fertilizer and, except for the N loss to the air, can be used by plants in the application year.
