Plant Mineral Nutrition
Elements mainly derived from soil in inorganic form are known as mineral elements.The three main sources of nutrients for plants are air, water, and soil. Elements obtained from air are known as non-mineral elements, such as carbon, oxygen, and hydrogen.Irrigation water is also a source of mineral elements from dissolved salts, …
