- •
Variability of precipitation is the primary limiting factor for most biotic processes.
- •
Grazing change the distributions of most topsoil parameters and strongly reduce SOC stocks.
- •
A mixed system of alternating hay and grazing mitigates negative effects of sole grazing.
- •
Small amounts of mineral N fertilizers could compensate losses by hay-making.
