Nitrogen Fixing Species for Agroforestry Systems
I am currently working on a Regenerative Landscape Design for a site in Todorovo, Bulgaria. The plan is to establish an Agroforestry system known as Alley Cropping wherein rows of mixed species edible trees and shrubs are planted at intervals with spaces for herbs, forage and/or grain crops to be grown in between. It's a dynamic system which is inherently diverse, providing multiple yields and excellent habitat for wildlife while at the same time being relatively resilient to a changing climate. The site design - Paul Alfrey An essential component of the design will be the Nitrogen fixing perennial plants within the community of fruit and nut trees. These plants will be pruned at regular intervals to provide biomass for surface mulch and to release a biological source of nitrogen to the surrounding productive plants and soil life by means of root shed associated with top pruning. When selecting plants for the Nitrogen Fixing component of this design, I was looking f...
