- Land tenure results in land fragmentation and dispute among farmers. It makes fertilizer use among farmers uneconomical due small farm size.
- Fertilizer formulation should be location base. The fertility evaluation of a particular location should be ascertained. Generally, tropical soils are inherently deficient of nitrogen and phosphorus and prone to erosion and leaching which further results to soil degradation.
- Tropical soils are fragile having low depth of organic matter, so organic manure should be included in fertilizer formulation and manufacture (organomineral fertilizer) to improve the soil organic matter.
- Farmers must be trained in the when and how to apply fertilizer. The major constrain in fertilizer use among farmers is distribution and availability to grassroot farmers in Africa.
