- Abstract
- Nitrate leaching decreases crop available N, increasing water contamination. But quantification of NO3- leaching below the root zone is difficult to measure without disturbing the soil in order to determine the contribution of each agricultural practice. A new Matlab version of the mechanistic nutrient and water balance model WAVE was applied in order to calculate drainage and N balance and compared with previous estimations. The model showed the capacity for the estimation, with very high accuracy, the water balance and soil temperature. This accuracy was lightly reduced when the N cycle was estimated. However, estimations were in accordance with observed data dispersion. So, further research is necessary in the N module of this new Matlab version, but it can be a very interesting tool for evaluation of different agronomic techniques, reducing fertilizer losses and NO3- leaching in the Mediterranean regions, where the amount and participation timing are often very uncertain
