Effect of Beef and Chicken Manure Compost on the Nutritional Content of Calcium and Phosphorus in Alfalfa

The general objective of this thesis was to determine the effect of beef and chicken manure compost on the nutritional content of calcium and phosphorus in alfalfa; the research was of experimental design and applied type; The following results were obtained related to the physical-chemical characteristics of the compost based on bovine manure, temperature of 25°C, pH of 7.8 and the concentration of nitrogen (1.44%), phosphorus (0.57%) and potassium (1.80%), while for the chicken manure-based compost a temperature of 27°C, pH of 7.5 and a concentration of nitrogen (1.80%), phosphorus (1.05%) and potassium (1.24%) were obtained. Where it can be deduced that the compost based on chicken manure contains a higher concentration of nitrogen and phosphorus. Finally, the values obtained in the loam soil applying compost based on bovine manure were 3.97% calcium and 0.39% phosphorus and in the sandy soil 3.35% calcium and 0.37% phosphorus were obtained in alfalfa; Therefore, it is concluded that applying compost based on bovine manure, better results are obtained in sandy and loamy soil, increasing the nutritional content of calcium and phosphorus in alfalfa.
