Abstract

composições para liberação prolongada de macronutrientes agrícolas e processos respectivos. uma composição de liberação prolongada de um macronutriente para o lócus de uma planta que contém um nanocompósito em que um composto de macronutrientes que contém nitrogênio absorvidos na superfície de nanopartículas de fosfato de hidroxiapatita é intercalado dentro do espaço entre as camadas de uma nanoargila. o nanocompósito contendo os compostos de macronutrientes absorvidos é lentamente liberado de maneira prolongada quando em contato com um solo ácido.
