Calculate soil nutrient balances.
Naebi is a computer application for calculating soil nutrient balances according to the fertilization ordinance. Besides preparation of annual and perennial balances the programme shows the distance to the legal upper limit of nitrogen out of animal manures (170 kg N/ha) and it calculates whether there is at least a six-month-long storage capacity for liquid manure (this is necessary since the 1st January 2009). The master data stored in Naebi for animal excreta, plant removal of nutrients, organic manure, etc. correspond to the conditions in Baden-Württemberg, so the data can be used as a basis for a manure management plan.
The Naebi programme is extensive and so it can be used for complex farms, for example branches like biogas production are stated separately.
