Abstract:

Files of demand (D) and supply (S) for nitrogen (N) and phosphorus (P) when N and P are considered as independent. All variables are in kg(N or P)/ha/yr. Dimension called "nmonte" correspond to monte-carlo simulations used to assess the uncertainty. D_N, D_P and S_P depend on crop while S_N does not. These variables are used in the computation of supply/demand ratios for nutrients considered as independent (Eq.1-2 of the associated publication) and for nutrients considered in interaction (Eq.7-8). They can also be used to compute nutrient limitations in crossed fertilization experiments (Eq.3-6 with A_N=30kgN/ha/yr and A_P=5kgP/ha/yr, as in the associated publication).

Difference with Version1: in Version 2, an issue with the unit of the potential yield (confusion between t/ha and tDM/ha) was corrected.
