 What is Fertilizer?  Some effective ways to use phosphorus fertilizers

Fertilization is extremely necessary to help plants grow and achieve high yields. In particular, phosphorus is one of the three essential macronutrients for plants, playing an important role in plant growth. Join Agri to find out what phosphate fertilizer is? Some ways to use phosphate fertilizers to improve crop efficiency.

  1. What is Phosphorus?

Phosphate fertilizer is one of the popular inorganic fertilizers for plants with its own uses besides combining with nitrogen and potassium fertilizers to form a mixture at the same time providing nutritional elements for plants.

Phosphate fertilizer contains the nutrient element phosphorus in the form of phosphate ion, used as fertilizer for plants. The nutrients of phosphate fertilizers are evaluated as a percentage by mass of P205 corresponding to the amount of P present in its composition. Apatite and phosphorus ores are often raw materials for the production of phosphate fertilizers.

  1. The role of phosphorus fertilizers for plants

In the growing period, phosphorus fertilizer is very necessary for plants, it has the effect of promoting the metabolic and energy processes of plants, making branches and leaves strong, seeds firm, fruits/bulbs large. Specifically:

  • Phosphate affects the transport of accumulated sugars and powders to particles and parts of protoplasm. Helps plants resist heat and cold. Besides, it also increases resistance to other adverse conditions such as drought, pests, waterlogging, etc.
  • It is essential for the formation of new plant parts, creating the active ingredients for flower sprout formation, branching, branching, flowering and fruiting.
  • Phosphate also has a buffering effect to help plants withstand acid and alkali.
  • Involved in respiration, photosynthesis and root development of plants.
  • Limit the harmful effects of excessive nitrogen fertilization.
  1. Expression of plants in the absence of phosphorus

When phosphorus deficiency occurs, crops are significantly affected resulting in low yield and poor quality.

  • Twigs and leaves grow poorly, fall a lot, the leaves are dark green at first, then turn yellow and turn purple-red (starting from the lower leaves first and from the edge of the leaf to the inside).
  • Phosphorus deficiency reduces the ability to synthesize powder, fruits are few, ripen slowly, flowers are difficult to bloom, fruits are often thick and spongy, fungi are easy to attack and easily rot.
  • Causing limitations in photosynthesis and respiration, affecting fruit set, reducing tolerance greatly affects crop yield.
  • Affects the quality of flowers, fruits and tubers.
  • Root growth is slow, the plant is short, affecting the absorption of nutrients by the plant.
  • Impediment to protein synthesis due to phosphorus deficiency leads to accumulation of nitrogen in the form of nitrate.
  • Leaves are shrunken, the lamina is narrow, and tends to stand upright due to stalled protein synthesis.

  1. Expression of plants when there is an excess of phosphorus

Compared to when plants are deficient in phosphorus, the expression of excess phosphorus in plants is more difficult to detect. Plants with an excess of phosphorus easily lead to a deficiency of zinc and copper.

Too much phosphate fertilizer will inhibit plant growth leading to excess pigment. When there is an excess of phosphorus, the plant will have the following symptoms:

  • Plants ripen too early, unable to accumulate high-yielding crops.
  • Phosphorus is a mobile element, so it can move from old organs to young organs and especially in growing parts.
  1. Techniques to improve the efficiency of phosphate fertilizer use

  • Phosphate fertilizer according to the soil: Depending on the nature, more or less acidity of the soil, choose the appropriate type of fertilizer. Use natural fertilizers for acid-poor phosphate soils, fused phosphate fertilizers for infertile soils, Mg-poor light soils and superphosphate for neutral alkaline soils. According to the mechanical composition of the soil: heavy soil, heavy meat when phosphate fertilizer is often retained, so it must be applied in rows and quickly absorbed by plants.
  • Phosphate fertilizer according to the tree: Rice should be fertilized with fused phosphate fertilizer or natural phosphate fertilizer. Preference should be given to phosphate fertilizers for plants with high demand, for dry crops, especially short-term plants, should be applied with super phosphate.
  • Phosphate fertilizer should mainly be used for lining, easy to digest like Super phosphate, it can be used for top dressing.
  • Phosphate fertilizer should be combined with additional essential trace elements, too much phosphorus fertilizer may cause the plant to be deficient in some trace elements.
  • Apply phosphorus fertilizer in the period when plants have a high demand for phosphorus (seedling fields, nurseries, when new plants are planted).
  • For shallow crops, often fertilize in holes, applying as many roots as possible.
  • Should be combined with manure in proportion to manure, 2% for superphosphate, 3-5% for phosphorus.
  • Combine superphosphate with other types of phosphorus in use to increase the efficiency of phosphate fertilizer use.

In addition, growers need to monitor the situation of their crops to take timely measures. Limit the use of chemical fertilizers instead encourage the use of more microbiological and organic fertilizers.

With the sharing from this article, hope to bring this information useful to readers. Makes it easier and more efficient to fertilize plants with phosphorus.
