Does fertilizer help plants grow

Does fertilizer help plants grow? To know that in addition to absorbing water from the soil, plants also absorb mineral elements and nitrogen and organic matter to maintain normal life activities. Therefore, the amount of mineral elements and organic matter in the soil directly affects the growth and development of plants. Under cultivation conditions, the type and amount of fertilizers can change the proportion of nutrients in the soil and provide a good nutrient environment for plant growth.

The effect of nitrogen fertilizer on plant growth

The nitrogen fertilizer absorbed by the root system is mainly inorganic nitrogen, namely ammonium nitrogen and nitrate nitrogen. It can also absorb some organic nitrogen, such as urea. Nitrogen is the main component of protein (including some enzymes and coenzymes), nucleic acid, and phospholipid. They are an important part of protoplasm, nucleus and biofilm, and have a special role in plant life activities. Nitrogen is also a constituent of certain plant hormones, which have a regulating effect on life. Nitrogen is a component of chlorophyll and is closely related to photosynthesis. Therefore, the amount of nitrogen will directly affect cell division and growth. When the supply of nitrogen fertilizer is sufficient, the branches and leaves are lush, the plants are tall, the branching ability is strong, and the protein content in live fruit planting is high. Among the essential elements of plants, in addition to carbon, hydrogen, and oxygen, nitrogen has the greatest demand. Therefore, the supply of nitrogen fertilizer is particularly required in agricultural production. Fertilizers such as human excrement, urea, ammonium nitrate, ammonium sulfate and ammonium bicarbonate are commonly used to mainly provide nitrogen.

Effects of Phosphorus on Plant Growth

Phosphorus is the main component of nucleic acids, nucleoproteins and phospholipids, and is closely related to protein synthesis, cell division, and cell growth; phosphorus is a component of many coenzymes and participates in photosynthesis and respiration. Phosphorus is also involved in the metabolism and transport of carbohydrates. In photosynthesis and respiration, the synthesis, transformation and degradation of sugars mostly react after phosphorylation; phosphorus also plays an important role in nitrogen metabolism and fat metabolism.
Phosphorus is involved in a variety of metabolic processes and has the highest content in the meristem with the most vigorous life activities. Therefore, the application of phosphorus fertilizer has a good effect on the growth of tillers, branches and roots. Phosphorus promotes the conversion and transport of carbohydrates and is beneficial for the growth of seeds, roots and tubers, which can significantly increase the yield of these crops. In addition, due to the close relationship between phosphorus and nitrogen, the effect of phosphorus fertilizer cannot be fully exerted when nitrogen is deficient. Only when nitrogen and phosphorus are used together can the effect of nitrogen fertilizer be fully exerted.

The effect of potassium on plant growth

Potassium promotes protein synthesis. When potassium is sufficient, more protein is formed and soluble nitrogen is reduced. The distribution of potassium and protein in plants is consistent, and the protein-rich parts such as growth points and cambium have higher potassium ion content.
