Abstract :
[en] European nitrate directive (CEE/91/676) imposes wide monitoring of Nitrogen in farmlands. The Walloon Region (South of Belgium – 750 000 ha of arable land) develops an original combination of methods to reach European objectives in this topic. On the one hand, water and nitrogen flows and balances are modelled, on the other hand, an Agricultural Surface Survey is put into practice to monitor nitrate nitrogen in the soil at the beginning of the leaching period. The Agricultural Surface Survey is constituted by a 30 reference farms network within more than 200 plots are monitored each in order to fix annual standards for nitrate profiles. Each year, about 1% of the Walloon farms are assessed about their good nitrogen management. Thanks to the existence of a useful database of nitrate profiles measured through six years in the whole Walloon Region, validation of the simulations in the vadose zone can be realised. The comparison of the measured data and the simulation shows a good accuracy of the EPICgrid model.
