How Do Agricultural Practices Implemented In Organic Systems Balance Soil Organic Matter Storage, Nutrient Availability And Resulting Crop Yields

In organic cropping systems, appropriate ecological agricultural practices (e.g., organic fertilization, rotation’s diversification with perennial crops) must induce a balance between yield and soil organic matter storage, to sustain production while preserving soils. Their efficiencies depend on the whole cropping systems, the type of soil, the considered time scale and the climate. We will illustrate this issue with research results obtained from 3 different field studies conducted in Quebec (Canada) and Brittany (France).
