Chemical elements play an important role in obtaining a bountiful harvest from agricultural crops. In our increasingly developing country, farming and the cultivation of agricultural crops are one of the most important processes. Light, heat, water and nutrients are essential for the life of plants. All of these conditions are equally valuable and very necessary. Plants contain more than 70 chemical elements, but 16 of them are very important for life. Of these, 3 elements are essential for plants. These are nitrogen, phosphorus and potassium minerals, which are essential sources of nutrients for agricultural crops. Nitrogen fertilizers increase the crop, phosphorus fertilizers increase the yield, and potassium fertilizers improve the quality of the crop, increase the plant's tolerance to heat and cold, drought, and resistance to pests.
