Tracking nitrogen losses in a greenhouse crop rotation experiment in North China using the EU-Rotate_N simulation model [PDF]

open access: yes, 2010
Vegetable production in China is associated with high inputs of nitrogen, posing a risk of losses to the environment. Organic matter mineralisation is a considerable source of nitrogen (N) which is hard to quantify.

soil organic matter

open access: yes, 2016
Soil organic matter (SOM) benefits the soil and the health of plants. The SOM is built and maintained by retaining crop residues, growing cover/green manure crops, crop rotation, and addition of compost and farmyard manure. Addition of organic matter to soil helps in water-holding capacity, soil quality, nutrient cycling, drainage improvement, and ...
