What chemicals containing minerals are added to soil to aid plant growth?

Chemicals containing minerals that are commonly added to soil to aid plant growth include nitrogen, phosphorus, and potassium, often referred to as NPK fertilizers. Additionally, amendments like lime (calcium carbonate) are used to raise soil pH, while gypsum (calcium sulfate) can improve soil structure and drainage. Micronutrients such as iron, zinc, and manganese may also be added to address specific nutrient deficiencies in the soil. These amendments enhance soil fertility and promote healthy plant development.
