The availability of nutrients in manure to a crop is dependent on the chemical makeup of the nutrients.
Organic nitrogen is determined by the difference between total nitrogen and ammonia nitrogen.
Once the manure in storage has been well-agitated, the manure should be sampled for nutrient analysis. Once handling of manure begins, volatile gases such as ammonia are given off and the nutrient value of the nitrogen in the manure decreases. Therefore, it is important to anticipate how much of a certain nutrient will be lost before it can be utilized by the crop. Volatilization of Ammonia Volatilization of ammonia represents a significant cause of nitrogen loss. 25-35 broadcast, immediate incorp.
