Soil fertility management in organic farming
Institute of Field and Vegetable Crops, Novi Sad
Abstract
The main objective of organic farming is to produce high-quality food without the use of agricultural chemicals while sustaining and increasing the organic matter content, biological activity and availability of nutrients in the soil. The amount of organic matter can be increased by growing legumes and by applying green and animal manure, which at the same time increases the availability of nutrients in the soil. However, maintain organic matter and increasing nutrient availability are not always compatible because mineralization that releases nutrients also destroys soil organic matter. Special consideration need to be given to the timing and intensity of management practice when trying to meet nutrient and organic matter management goals. The ultimate goal is to provide a continuous supply of nutrients while preventing loss of SOM. As it is not always possible to satisfy the needs of the crops by applying only organic fertilizers, the use of natural mineral fertilizers is also allowed.
