In the past 40 years, technologies to improve the productivity capacity of Nigerian soils have been generated. Unfortunately, these technologies have not been transferred to or implemented by the intended beneficiaries. The known technologies for restoring soil fertility can be grouped as follows:
Agriculture can only be persistent and sustainable when the technologies are developed with the participation of the end users (and taken into consideration these clients’ needs, means and circumstances). As much as possible, local institutions should lead the way but with adequate support from external research and development institutions. Sustainability is also enhanced by the existence of an enabling policy environment. Constraints that impinge on one or more of the technologies previously listed are as follows :
1. Mineral fertilizer use is hampered by unavailability of capital and credit, by national and international disincentives, by poor marketing and pricing, and by gender bias.
3. Use of organic inputs is limited mainly by lack of labor and sheer relative scarcity as a result of multiple uses.
