The width of this range depends on individual plant species and the particular nutrient.
Plant nutrition is the study of the chemical elements and compounds that are necessary for plant growth, and also of their external supply and internal metabolism.nutrients that are crucial for plant growth include macro and micro nutients like nitrogen, phosphorous, pottassium, sulphur, magnesium, iron, boron, zinc, copper, molybdenum, calcium, cobalt,nickel, sodium and silicon.
