What are the advantages of alley cropping?

Alley cropping is an agroforestry practice that involves planting rows of trees or shrubs alongside crops. This method offers several advantages, including improved soil fertility through nitrogen fixation and organic matter addition, reduced soil erosion by providing ground cover and windbreaks, and enhanced biodiversity by creating habitats for various species. Additionally, alley cropping can increase overall farm productivity by allowing for simultaneous cultivation of trees and crops, optimizing land use and potentially providing multiple sources of income.
