Soil enrichment in the nursery and established fields are unavoidable. Deforestation and desertification as an agent of edaphic destruction in parts of the country call for the soil and soil restoration. This will assist in improving the yield and growth vigour of seedlings and tree. This study surveyed the effects of nitrogen, phosphorus and nodulation formation on the growth of the seedlings and stands. Fertilizer recommendation for soils and tree seedlings is a dynamic process in view of generation of the new knowledge, changes in the soil nutrient status, changes in plants and planting patterns and associated management practices. Application of nitrogenous and phosphorus fertilizers are more importance practice in nursery establishment. Faiherbia albida and Leucanea leucocephala observed to fix nitrogen to the soil while mycorrhiza is essential for Pinus caribea (Pines) propagation. Training and educative programmes are essential for the forest workers in order to boost productivity and exposed them to nursery techniques. Concerned people and organizations must provide farm inputs, incentives and subsidies to the forest nurseries operators and farmers where and when necessary.
