Phosphorus in wheat

Phosphorus is especially important in cereal cultivation. Phosphorus fertilizers can compensate for soil fertility that has been reduced by repeated crops. Phosphorus consumption in the early stages of growth (about the first 5 to 6 weeks) plays an important role. Adequate and strong tillers play an essential role in increasing wheat production, and this can be achieved through the effect of phosphorus on root development and growth.

Phosphorus salts are not evenly distributed in the soil due to their low solubility. It produces salts in acidic soils with aluminum and iron, and in alkaline soils with lime, which are difficult to dissolve and difficult to use by plants. Not all phosphorus fertilizers are absorbed by plants in the first year, but some They will be used in later years.

The effect coefficient of phosphorus is high. Therefore, after examining the nutritional needs and, if necessary, by consuming less phosphorus fertilizers (compared to nitrogen fertilizers), the maximum yield can be harvested. Phosphorus plays a very important role in vital and structural functions (photosynthesis, cell division and respiratory reactions). Phosphorus is important in creating abundant roots, tillering, increasing grain weight and cooking quality, formation of sugars in the crop and soil fertility.

Phosphorus deficiency causes slight root growth, discoloration of the leaves from green to purple or red, and the onset of wilting at the tips of the leaves and discoloration of the stem (dark bluish green), and in fact the more severe effects of deficiency on the spike It can be seen.

Severe phosphorus deficiency in wheat phosphorus does not move significantly in the soil, so seedlings with small root systems can use more phosphorus in the soil than larger plants.

Phosphorus deficiency in wheat causes physiological stresses and provides the conditions for the development of diseases such as root rot (Pythium).

Phosphorus deficiency is most concentrated in cold, moist, high-calcium, exchangeable aluminum soils.

To increase the efficiency of phosphorus fertilizer application, the following points should be considered:

  • Application of phosphorus fertilizer in strips, especially in acidic and alkaline soils
  • Use efficient figures
  • Consume enough other nutrients
  • Weed control
  • Adequate water consumption

Application of phosphate fertilizer near the roots is effective in improving the deficiency because this element is relatively immobile in the soil. Phosphorus fertilizers must be applied to the soil before planting and for cereals in the fall. In order to recommend the use of phosphorus fertilizer, a soil test should be performed and based on that recommendation.
