Estimate of nutrients of fym To determine how much manure is needed for a specific application, the nutrient content and the rate nitrogen becomes available for plant uptake needs to be estimated Nutrient content of manure varies depending on source, moisture content, storage, and handling methods
Estimate of nutrients of FYM ▪ To determine how much manure is needed for a specific application, the nutrient content and the rate nitrogen becomes available for plant uptake needs to be estimated. ▪ Nutrient content of manure varies depending on source, moisture content, storage, and handling methods
Estimate of nutrients of fym Nitrogen content in manure varies with the type of animal and feed ration, amount of litter-干草, bedding垫料 or soil included, and amount of urine concentrated with the manure Generally, dry manure contains 1.5 to 2. 2 cubi meters per ton. Dry poultry manure contain around 1. 9 cubic meters per ton

Nutrient availability of organic manure Most of the n in manures occurs in organic compounds In slurries about half of the total n consists of nh t the remainder being organic N Only about 25% of the organic N is mineralized. The remaining organic fraction is very stable
Nutrient availability of organic manure ▪ Most of the N in manures occurs in organic compounds. In slurries about half of the total N consists of NH4 + the remainder being organic N. ▪ Only about 25% of the organic N is mineralized. The remaining organic fraction is very stable
