  1. Plant new hedges

    A 1997 review of case studies in sub-Saharan Africa, gathered from published literature (Kang, 1997) reported that woody species in alley cropping systems can improve nutrient recycling, reduce soil nutrient loss, encourage soil animal activity, control erosion, improve soil fertility and sustain levels of crop production. Legume species suitable for alley cropping include: gliricidia Gliricidia sepium, Leucaena Leucaena leucocephala, pigeon pea Cajanus cajan, calliandra Calliandra calothyrsus, mountain immortelle Erythrina poeppigiana, apa apa Flemingia macrophylla, and Christ thorn Dactyladenia barteri. In alley cropping multipurpose trees and shrubs and food crops are intercropped (two or more crops grown between the rows of another).
