Abstract

composição macronutriente de liberação constante baseada em celulose para aplicação de fertilizante. uma composição macronutriente de liberação constante para um local de plantação com composto macronutriente contendo nitrogênio adsorvido sobre a superfície de nanopartículas de fosfato de hidroxiapatita, e um processo de preparação da mesma. as nanopartículas de fosfato de hidroxiapatita com macronutriente adsorvido são encapsuladas dentro de cavidades presentes em madeira de modo que a biodegradação da madeira libera para o solo os compostos nmacronutrientes adsorvidos de uma forma lenta e constante. além disso, as partículas de macronutrientes são encapsuladas dentro das cavidades da célula da madeira é revestida com nanopartículas de fosfato de hidroapatita modificadas por celulose de forma que a ruptura do nanorrevestimento inicia a liberação de nitrogênio e em seguida a biodegradação da madeira libera para o solo o restante dos compostos macronutrientes adsorvidos de uma forma lenta e constante.
