Perspective Chapter: Novel Slow-Release Nanocomposite Fertilizers

Abstract

Slow-release fertilizers (SRF) create a physical barrier and prevent the rapid release of nutrients. These fertilizers are produced in two ways: coated and matrix. SRFs can reduce nutrient loss such as nitrogen and cause gradual use according to the plant’s needs. This will increase productivity and make fertilizer more effective. The process of producing fertilizers is increasing every year in the world. It can also be predicted that this trend will continue in the coming years. Nanotechnology-based fertilizers also are a new strategy to enhance agricultural yields and show great potential as viable options in the fertilizer industry. Recently slow- and controlled-release nano-fertilizers (SRNF and CRNF) have advanced through the improvement of nanocomposites or coating techniques with the help of various chemical things. SRNFs are more effective than usual nano-fertilizers because these deliver elements in a controlled method and can be adjusted by many environmental and physical motivations (such as pH, temperature, humidity). The application of controlled-release fertilizers reduces nutrient loss due to evaporation and leaching and provides a carefully designed nutrient-release system that is aligned with the goal of sustainable agriculture.
