Manure management practices in Lombardy (Italy)

At present, the database includes plans for more then 5500 farms representing more then one million cattle and 3.5 million pigs. The information contained in the database allows an evaluation of manure management practices in the Region. Some indicators like nitrogen amount per hectare varies from 100 to 300 kg at the same level of crop requirement and therefore do not seem adequate to evaluate the pollution risk at farm level.
