Quantitative farm analysis requires a lot of information from the individual farms and a lot of calculations. For this purpose this computer model was made in a spreadsheet program. The FARM-model looks at a farm on the fields of mineral balance, soil organic matter development, animal nutrition, labour and economics. It can be used to look at existing farms, to study the effects of changes in existing farms, to create new farms. It contains a module for composing fodder rations using Quattro's linear programming function. Input data: Crops (area, yield, activities), animals (number, weight, growth, production, activities), fodder rations, machines, buildings.
