Satellite Symposium 1: Optimisation
Description
Key points
1. Legume/grass pastures retain feedbacks on N supply that may help to reduce losses of N to the wider environment.
2. Intensive use of N fertilisers tends to increase SOM turnover and increase losses of N to the environment.
3. Increased use of fertilisers has contributed little to soil organic matter storage in grazed pastoral systems.
