NUTRIENT DEFICIENCY IN MULBERRY - CAUSES AND REMEDIES

摘要

Of the 16 elements required by plants for various metabolic processes, carbon, hydrogen and oxygen are supplied by water and atmospheric carbon dioxide. The major nutrients viz., Nitrogen (N), Phosphorus (P) and Potassium (K) are by and large deficient in most of our soils and as such, need to be supplemented in large quantities by fertilizer application. Calcium, magnesium and sulphur are known as secondary elements. These are also known as amendment elements because of their use in reclamation of acid and alkali soils.
