Choosing the right fertilizer that provides essential nutrients to crops and restores soil fertility among various types of fertilizers can be challenging. Additionally, the diverse composition and formulation ratios make it difficult for farmers to select the most suitable fertilizer. To address this, the "Soilath® Blender," a blended fertilizer manufacturing plant, has been developed to automatically calculate the required amounts of nitrogen, phosphoric acid, and potassium. This innovation aims to assist farmers in making informed decisions and optimizing their fertilizer choices.
