- Abstract
The manufacturing of bovine bone ash is a low cost and easy production process which can be adopted for making good use of animal residues, in locations without infrastructure, such as the family production units. This study aimed at describing the manufacturing process of bone ash and characterizing the physical and chemical parameters of the resulting material for organic fertilization. The experiment was performed with three replications, being evaluated the bovine bone ash manufacturing process yield, as well as its density, water retention capacity, pH of the resulting material after burning and contents of total calcium, calcium soluble in water, total phosphorus and phosphorus soluble in citric acid and in ammonium citrate. The process resulted in an average yield of 24.4% and the bovine bone ash presented 33.07% of total calcium, 15.6% of total phosphorus, 10.4% of phosphorus soluble in citric acid, pH of 9.94, density of 0.89 g cm-3 and water retention capacity of 73.3%. The bovine bone ash showed promising characteristics, with potential for being used as source of phosphorus and calcium in the organic fertilization process.
