Abstract

Agroforestry has been in practice for thousands of years. However agroforestry as a science has evolved recently. It is believed that agroforestry promotes more efficient cycling of nutrients than agricu1ture. Agroforestry systems are thus perceived to improve or maintain soil fertility promote soil conservation, reduce soil degradation and achieve sustainable production. However the beneficial effect of trees on agriculture systems is a recent area of investigation. Many of the perceived benefits of trees in agroforestry systems are still hypothetical. This paper reviews the perception of agroforestry systems in improving soil fertility.
