Abstract
[Extract] IN-Palm is an agri-environmental predictive indicator specific to oil palm plantations based on an operational model. It simulates the risk of nitrogen (N) losses from the field, through 6 loss pathways: ammonia (NH3) volatilisation; N losses through runoff-erosion; nitrous oxide (N2O), dinitrogen (N2) and nitrogen oxides (NOx) emissions; and N leaching. Simulations require 21 readily available input variables on crop factors, soil, weather and management practices. Calculations are done for one hectare of palms, for an age of palms chosen by the user, from 1 to 30-year-old.
