Assessment of nitrogen content in buffalo manure and land application costs

(in lingua inglese)

Results show that there is lower nutrient content in buffalo manure than in cattle manure. This agrees with findings of Campanile et al. (2010). Immediate incorporation is the most environmentally sustainable manure application technique when ammonia volatilisation is considered, but it is the most expensive (approx.1.19 €/kg of nitrogen per field). It also requires longer lead-time, mainly in the two pre-sowing periods; pre-sowing periods are extremely short in southern Italy.
