Abstract

The present invention relates to coating formulations. and the process of preparing controlled-release chemical fertilizers. Supplementary nutrients in the form of nanometer-scale oxide compounds. by controlled release fertilizer products that It is coated with a natural polymer base along with additional nutrients in the form of Na-level oxide compounds. Nometer according to this invention It is the development of a new type of coating formula. To have elements of nutrients Supplements necessary for plant growth which is classified as an invention that recognizes the importance of bringing elements Supplements that are important to plants at the nanometer level are applied in agriculture. that can help Promote increasing the properties of controlled release fertilizers to make them even more special. Advantages of controlled fertilizers Released according to this invention is that plants will receive nutrients for a long time and continuously. It also has nutrients. Supplement according to the needs of the plant Because in this invention, additional nutrients are added to plants in the form of Nanometer-scale oxide compounds This is considered to add properties to the fertilizer coating in the original formula. It had been developed before. This invention is not only classified as an invention that can help solve problems. farmers in a direct way, for example by reducing the cost of using more fertilizer than necessary But indirectly, it is considered to help solve problems or reduce negative impacts on the environment, such as reducing the amount of chemicals that accumulate in the environment as well.
