Raw materials in agriculture are an important part of agricultural production processes. These materials include fertilizers such as nitrogen, phosphorus and potassium that are produced from mineral sources or chemical processes, pest control products such as insecticides and herbicides, as well as materials used to control plant diseases and infections. Examples of primary chemicals in agriculture are ammonium nitrate (a nitrogen fertilizer), triple phosphate (a source of phosphorus), and potassium sulfate (a source of potassium), which are used as staple fertilizers. Also, chemical products such as imidacloprid (insecticide) and mancosebutene (herbicide) are primary chemicals used in agriculture. The effective and balanced use of these materials in agriculture can help improve the yield and performance of crops.
