Third,what nutrients are called macronutrients?
These 16 elements are necessary for the growth and development of plants, but there are great differences in their requirements. Traditionally, carbon, hydrogen, oxygen, nitrogen, phosphorus and potassium are called as a large number of elements.
Fourth,what nutrient elements are called medium elements?
Among the 16 elements necessary for plant growth and development, medium amounts of calcium, magnesium and sulfur are called medium amounts.
Fifth,what nutrients are called trace elements?
