Article Title: Environmental Effects of Application of Fertilizers and Pesticides on Water and Soil in Ibadan, Nigeria
by Afolabi T. Morakinyo, Omotayo B. Adeboye, Olusegun T. Awogbuyi

Protection of natural resources is of priority to government, non-governmental organizations and individuals. Effort had been made and financial resources had been expended on researches that examine and investigate point-and non-point-source pollution. This article presents the outcome of field investigations carried out on a stream that passes through Institute of Agricultural Research and Training (I.A.R & T) Moor Plantation, Ibadan, Nigeria. The analysis of water samples shows that there is an environmental pollution due to the high concentration of potassium and phosphate. The amount of phosphate in the water and in the soil was found to be 14.2 and 11.19mg/1 respectively, which are beyond the tolerable limit of 30g/l. This will support the aquatic growth such as algal boom. In extreme cases, it will result to methemoglobinemia with bluish discoloration of infant referred to as Blue baby. Chlorinated pesticides being used at Institute of Agricultural Research and Training (IART) has released chlorine of 151.2 mg/1 to the water course that runs through the villages, making use of this surface water course that runs through the villages, for their domestic purposes at the downstream,. This will create health challenges such as persistent hemdytic anemia and dialysis for the inhabitants of the area. However, such effluent from I.A.R.&T must be biodegraded before discharging into the watercourse in order to prevent environmental pollution.
