Calculate your manure surplus

From 2026 the 170 kg N/ha limit applies: your placement capacity is hectares × 170 kg N. If your livestock produces more, you have a surplus to dispose of — often at high cost. This calculator shows your estimated capacity, production and surplus, plus cost indication. So you know where you stand before looking on the market.

Enter number of cows, pigs and your hectares. The result is an estimate based on the 170 kg N/ha rule (2026)..
