Agroecological practices build soil fertility from "summary" of Growing a Revolution by David R Montgomery
Agroecological practices involve techniques that work with nature rather than against it. By mimicking natural ecosystems, farmers can build soil fertility over time. One key aspect of agroecology is maintaining ground cover, which helps protect the soil from erosion and retains moisture. This can be achieved through practices such as cover cropping and agroforestry. Another important component of agroecological practices is crop diversity. Planting a variety of crops helps improve soil health by promoting biodiversity underground. Different crops have different root structures, which can help break up compacted soil and improve drainage. In addition, diverse cropping systems can help suppress pests and diseases, reducing the need for chemical inputs. Crop rotations are also a common practice in agroecology. Rotating crops helps prevent nutrient depletion in the soil and reduces the buildup of pests and diseases. By rotating nitrogen-fixing legumes with other crops, farmers can naturally replenish soil nutrients and reduce the need for synthetic fertilizers. Furthermore, agroecological practices often include the use of organic matter to improve soil structure and fertility. Adding compost, crop residues, and other organic materials to the soil can increase microbial activity and nutrient availability. This can help improve soil structure, water holding capacity, and nutrient cycling, leading to healthier and more productive soils.- Agroecological practices focus on building soil health as a foundation for sustainable agriculture. By working in harmony with nature, farmers can improve soil fertility, reduce the need for chemical inputs, and create resilient and productive farming systems. Through thoughtful management of soil health, farmers can establish a regenerative cycle that benefits both the land and future generations.
