Managed Land

The managed land module consists of several components: (i) Crop and grass production model (yields of food and feed crops, energy crops and grass); (ii) Nutrient management Model (nutrient requirements in relation to yields, and fertilizer use efficiency to compute fertilizer inputs and animal manure management systems) and (iii) Carbon plantations model (carbon plantations).
