Chemical Components and Effects on Soil Quality in Temperate Grazed Pasture Systems

Abstract

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
