Fruit farming

Cover crops are planted before or during the establishment of orchards primarily to improve soil health and protect the land from degradation. These fast-growing crops, such as rye or vetch, serve several critical functions:
- Erosion Control: They prevent soil erosion by protecting the surface from wind and water runoff, which is particularly important when the soil would otherwise be left bare.12
- Nutrient Enhancement: Cover crops can increase soil fertility and add organic matter. When used as green manure, they are plowed under to release nitrogen and other essential nutrients into the soil.12
- Soil Structure: They help maintain a loose, friable soil structure, preventing the compaction that often results from clean cultivation.3
- Moisture and Leaching Management: They can reduce nutrient loss from leaching and improve the overall physical condition of the soil.2
While they offer significant benefits, farmers must manage them carefully to ensure the cover crops do not compete excessively with the young fruit trees for water and nutrients.32
