Soil nutrients research involves studying the various essential elements and compounds present in the soil that are necessary for plant growth and development. This includes macronutrients such as nitrogen, phosphorus, and potassium, as well as micronutrients such as iron, zinc, and manganese. Researchers in this field seek to understand how these nutrients interact with soil particles, microorganisms, and plant roots, as well as how they are absorbed and utilized by plants. The aim of soil nutrients research is to optimize soil fertility and nutrient availability to ensure sustainable crop production and overall ecosystem health.
