The nature and use
of phosphate fertilizer
phosphate fertilizer is a chemical fertilizer with phosphorus as the main nutrient, which plays an important role in promoting plant growth and increasing crop yield. In the field of chemical production raw materials, phosphate fertilizer is an important additive, which is widely used in agriculture, forestry, animal husbandry and other fields. This article will detail the nature and use of phosphate fertilizer.

1. the nature of phosphate fertilizer

1. physical properties
phosphate fertilizer is generally white or off-white powder or particles, with high hygroscopicity, soluble in water. Different types of phosphate fertilizer, its physical properties are also different, such as calcium magnesium phosphate fertilizer is gray brown particles, superphosphate is dark gray powder.

2. chemical properties of
phosphate fertilizer in the main component of phosphorus in the soil with calcium, iron, aluminum plasma combination to form insoluble phosphate, these phosphates can be absorbed by plant roots. Phosphorus in phosphate fertilizer generally exists in the form of orthophosphate, which has strong acidity, so it is necessary to pay attention to the interval between the use of alkaline substances.

2. the use of phosphate fertilizer

1. to promote plant growth
phosphorus is one of the essential nutrients for plant growth, for plant root growth, photosynthesis, energy metabolism plays an important role. The application of phosphate fertilizer can promote the growth of plants and improve the yield and quality of crops.

2. improving soil
phosphorus in phosphorus fertilizer can be combined with calcium, iron and aluminum in soil to form insoluble phosphate, which can increase soil acidity, promote soil microbial activity and improve soil fertility.

3. Improve the resistance of plants The application of
phosphate fertilizer can improve the resistance of plants and enhance the adaptability of plants to drought, cold, salinity and other adversities.

4. used in animal husbandry
phosphate fertilizer can be used in animal husbandry, as animal feed additives, promote the growth and development of animals and improve their productivity.

In short, phosphate fertilizer plays an important role in the field of chemical production raw materials. It can promote plant growth, improve crop yield and quality, improve soil, improve plant resistance, and can be used in animal husbandry as animal feed additives. When using phosphate fertilizer, it is necessary to apply it reasonably according to the soil conditions and the needs of plants to avoid waste and pollution of the environment.
