Optimises farm manure valorisation by quantifying the different types of farm manure produced (liquid and solid) and their mineral content (N, P, K) as well as their financial value.
It estimates for each plot, the effective N, P and K demand of crops and grassland, taking into account the previous fertilizations, and the pastures restitutions, resulting in a manure application proposal taking into account the agricultural and legal or environmental constrains.
VALOR favours the maximal efficiencies by giving crops and periods priority spreading coefficients. The program has a double approach: global at farm level and a specific at plot level.
The software and the user’s guide are both available on CRA-W website: www.cra.wallonie.be/valor.
