Animal manures are valuable sources of nutrients and the yield-increasing effect of manure is well established and apart from the nutrients in manure, its effects on the improvement of soil organic matter, soil structure and the biological life of the soil (Gabriel, 2010).Application of poultry or chicken manure which is the most widely used for growing crops increase the growth of crops (Mogapi, 2013)
Most of the nutrients in organic fertilizers are organically bound and because of this, they will become available to the trees successively when the organic matter is decomposed (Anna, 2013).The enhancement of soil fertility factors by using organic fertilizers causes an immediate improvement in the utilization of mineral fertilizers because there is growing interest in the use of organic manures due to soil fertility depletion in most African soils coupled with scarcity and cost of mineral fertilizers (Oyewoleetal., 2014).

2.5.2 Use of Inorganic Fertilizers
Chemical fertilizers are used in modern agriculture to correct known plant nutrient deficiencies; to provide high levels of nutrition, to aid plants in withstanding stress conditions; to maintain optimum soil fertility conditions and to improve crop quality.NPK fertilizers are required greatly by crops for healthy development and crop quality (Okolipsoet al., 2015)
