The effects of livestock’s waste utilization as fertilizer on coffee plant’s growth

Soil quality Cattle manure contains high organic matter and commonly used as plant nutrients in a form of organic fertilizer. The objectives of this research were to determine the influence of liquid and solid manure from livestock as fertilizer on soil quality and to study the effect of both liquid and solid fertilizer on coffee plant growth. In this research, Completely Randomized Design (CRD) was employed and the collected data was analysed using ANOVA. The F statistical test was applied to measure whether all independent variables could influence the dependent variable by using 5% and 1% (Alpha) degrees. The results showed that one time application of fertiliser from livestock’s liquid manure improved soil’s chemical properties such as C-organic, N, P, CEC, Ca and Mg, while soil chemical properties of pH, K, Na decreased. Two times application of livestock’s liquid manure fertilizer treatment improved soil chemical properties of pH, N total, Ca, Mg and saturation bases. As for livestock’s solid manure, one time treatment increased chemical properties of pH, C organic, N total, Ca and saturation of the base. The two times treatment was also found to improve soil’s chemical properties of pH, N. total, P, Ca, Mg, base number and base saturation. Livestock’s liquid manure fertilizer was also found to provide significant effect on the coffee plant height and quality. Additionally, livestock’s solid manure (i.e. compost) was found to have a significant effect on plant height, plant height rate and number of buds.
