Application of Microbial Bacteria to Solve the Problem of Sulphur-Deficient Soil in Fertilizer Plants
Many growers have reported that in the past, the use of low concentrations of calcium phosphate did not result in the lack of sulfur in the soil. Recently, the use of high concentrations of heavy calcium superphosphate has caused soil sulphur deficiency in some plots. Why is this? Speaking of this issue, you only need to understand the main components of the two.
The main component of calcium phosphate is calcium monophosphate, 14%-l8% phosphorous, and calcium sulfate, which accounts for about 50%. Therefore, the application of universal calcium phosphate can not only provide the crop with abundant phosphorus, but also enable the crop to obtain sulfur. However, since calcium superphosphate contains many sub-components and low phosphorus content, in order to overcome this shortcoming, it has been able to replenish calcium phosphate as a phosphate fertilizer. The heavy calcium superphosphate has been improved in the manufacturing method. It does not contain impurities such as calcium sulfate, and the content of phosphorus is greatly increased, and it becomes a high-concentration phosphate fertilizer. Because of this, without the supplement of sulfur in the superphosphate, the application of heavy calcium phosphate soil throughout the year is prone to sulphur deficiency.
Sulfur deficiency in crops is very similar to nitrogen deficiency symptoms. The main feature is the chlorotic chlorosis of leaves, but from the subtle manifestations, they are different: The symptoms of nitrogen deficiency begin with the lower old leaves, and the symptoms of sulfur deficiency are Start from the upper new leaf.
For the above problems can be used to solve the microbial bacteria fertilizer. Jinbao microbial manure is a high-tech product developed according to the principle of plant nutrition physiology and rhizosphere soil microecology. The main component is a complex microbial fermentation microflora and trace elements, among which the microorganisms have the functions of dissolving potassium, fixing nitrogen and activating soil. The role can make the crop root system around the formation of a particularly favorable micro-ecological environment, can promote the development of plant roots, enhance the ability of crops to resist salinity and drought, and promote crops on nitrogen, phosphorus, potassium, sulfur, iron, manganese and other nutrients Absorption, regulation of the pH of the soil enhances the defense of the crop against common high incidences such as withering and yellowing. After using this product, it can increase production, increase fertility, enhance stress resistance, early maturing and high yield, reduce costs and increase efficiency. Through the action of microorganisms, various elements that are activated in the soil are increased, the utilization of various elements by plants is increased, the amount of chemical fertilizers is reduced, the yield is increased, and the pesticides and heavy metals are reduced, and there is no pollution at the same time. The ecological environment is green and the growers are Essential fertilizer.
Therefore, when planting sulfur-loving crops, it is recommended that calcium phosphates be used in combination with microbial fertilizers, or that calcium phosphate and heavy calcium phosphate be alternately used together with microbial fertilizers, so that high-concentration phosphate fertilizers can be applied year-round. The problem of sulfur deficiency was alleviated.
