Plant Nutrition and Rational Fertilization What are the necessary nutrients for the normal growth and development of higher plants?
More than 70 chemical elements can often be detected in plants, but only 16 internationally recognized essential nutrients for the growth and development of higher plants are carbon (C), hydrogen (H), oxygen (O), and nitrogen. (N), P, K, Ca, Mg, S, Fe, B, Mn, Cu, Zinc (Zn), molybdenum (Mo), and chlorine (C1). According to the amount of plants they need, they can be divided into a large number of nutrients, medium nutrients and micronutrients. Numerous nutrients include carbon, hydrogen, oxygen, nitrogen, phosphorus, and potassium; moderate amounts of nutrients include calcium, magnesium, and sulfur; trace elements include iron, boron, manganese, copper, zinc, molybdenum, and chlorine. Now some scholars think that nickel (Ni) is the 17th essential nutrient.
According to research, the three conditions identified as essential nutrients for plants are: (1) This element should be essential to the vegetative growth and reproductive growth of the plant. When it is completely lacking, the plant cannot complete its life cycle; The need for this element is specific, and other elements cannot replace its role. In the absence of a plant, there will be a special lack of symptoms. Only by satisfying this element will the symptoms be eliminated; 8 this element must be in the plant It works directly, not just as an indirect action to improve the plant's growing environment.
