Abstract

Encouraging the development of sustainable agriculture is very important to reduce the negative effects of land overuse. Enhanced efficiency fertilizer combined with sustainable policies improves the effectiveness of fertilizer use. However, there is a gap in the literature to comprise how these materials behave concerning biodegradation, release in water, and soil, demanding more research. Composites of poly (3-hydroxybutyrate), sugarcane bagasse fibers, and potassium nitrate were melting-processed in an internal mixer chamber with different approaches to best trap the nutrient. For this purpose, we evaluated the composites regarding the nutrient release, in water and soil, and biodegradability. In water, the material with fibers released 20% less fertilizer than those without fibers during the first 9 h. The mathematical modeling performed to the release data indicated a predominance of the Peppas-Sahlin model among the three models studied. Also, fibers induced a decrease in nutrients lixiviation and favored biodegradation due to polymer crystallinity reduction. Sugarcane bagasse composites display the potential to slow the nutrients release and reduce the amount of polymer. (C) 2021 Elsevier B.V. All rights reserved. (AU)
