silage), soybeans, oats, wheat, alfalfa, grasses for forage and grazing,
switch grass
Commercial fertilizers and manure spreading plans
Biomass handling & storage (under development)
Investments in land, machines, and buildings; bank loans Simulation Results
Livestock imports and exports at farm level
Crops, forages, biomass balance at farm level
Nutrient balance and leaching/runoff potential (N-P-K) and aerial
emissions at field level
Soil erosion and soil carbon balance at field level
Energy consumption for traction
