Abstract:
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.
