Abstract

Encouraging the development of sustainable agriculture is very important to reduce the negative impacts of overuse of the land. In this way, the use of intelligent materials that release nutrients in a prolonged way, associate with sustainable policies, can contribute to greener agriculture. It is interesting these materials are obtained through green processes and use biodegradable materials in their formulations. Based on this premise, the objective is to develop materials with macro and micronutrients in the same formulation. First, microspheres loaded with micronutrients will be produced through the spray drying technique and then, added to a PVA matrix with macronutrients through thermal processing. Based on this methodology, it is expected the macronutrients will be first released, and after the micronutrients, since they are coated an extra layer of starch. The materials will be evaluated for nutrients release in water and soil, as well as characterized in structural, thermal and morphological form. (AU)
