TL;DR: The effect of neem on poor sandy upland soils at Majiya plantation near Sokoto appears to improve these marginal soils considerably.
Abstract: Neem (Azadirachta indica) is a deciduous tree, native in India, which has been widely introduced into the arid and semi-arid parts of the tropics. It is easily established without irrigation in northern Nigeria and grows rapidly, providing fuel and timber in 5-7 years. Unlike most trees and shrubs in Africa, neem trees are seldom if ever browsed and are therefore seldom damaged by wandering animals. This note describes the effect of neem on poor sandy upland soils at Majiya plantation near Sokoto. The tree appears to improve these marginal soils considerably.
