The use of fertilizers in agriculture, in particular those of livestock origin, is one of the most significant sources of diffuse water pollution. In this context project ReNuWal, funded by Fondazione Cariplo, aims to i) identify suitable methods to optimize fertilization at farm level and ii) develop innovative techniques for nutrient processing to limit surpluses and the emissions of nutrients, improving the efficiency with which they are used. This paper describes the software tool developed. The approach used for the software tool is to compare the characteristics of the manure produced in a farm with the crop requirements, considering also distribution methods used. Thus, it is possible to evaluate if additional treatments are needed to reduce the nutrient surplus or to improve the manure use efficiency. Furthermore, an assessment of nitrogen losses to air and nitrogen and phosphorus losses to water based on the methods used to manage and spread the manure can be obtained. Using this tool, a farmer can evaluate possible improvement of nutrient use efficiency and reduce fertilization cost due to mineral fertilizers.
