Comparative Analysis of Animal Manure for Soil Conditioning

Soil fertility is the potential of the land to grow plants. Soil will remain fertile until its nutrients level will not decrease. Due to intensive use of fertilizers soil state gets eroded and the micro and macronutrients are depleted which results in stunted growth of plant. Four different animal manure samples namely cow dung, horse manure, goat manure & chicken droppings were taken in order to analyze their nutrient content. Comparison of the results showed that goat and chicken manure has more potential of providing nutrients mainly phosphorous (P) and nitrogen (N) respectively than other manure samples. The highest amount of potassium(K) i.e 1.24 % was also delivered by the chicken droppings . Goat manure increased the phosphorous percentage in the soil by 0.30%. Nitrogen analysis in the animal manure showed that chicken droppings has the highest amount of nitrogen (2.06%). Resultantly, combination of goat manure of 60kg and chicken droppings of 40kg gave a suitable organic fertilizer with NPK ratio of (5:1:4) for the soil fertility with less amendment of inorganic fertilizer such as DAP (Di ammonium phosphate) which will balance the phosphorus deficiency in the NPK ratio.
