What happens after applying high-concentration phosphate fertilizer?
What happens when high-concentration phosphate fertilizer is applied? Please explain that the main component of ordinary superphosphate is monocalcium phosphate, and the fertilizer contains 14%-18% phosphorus; the secondary component is calcium sulfate, accounting for about 50%. Therefore, applying ordinary superphosphate not only provides crops with phosphorus nutrition, but also allows crops to obtain sulfur nutrition. However, superphosphate...

Rational application methods and technical key points for potassium fertilizer
Strawberries bloom and bear fruit continuously, with many flowers and a large fruit load, and a long flowering and fruiting period, so they consume a lot of phosphorus and potassium fertilizer. Once phosphorus is deficient and potassium is low during the flowering and fruiting period, cold resistance will decrease, few flowers will form, flower buds will be weak, and flowering and fruiting will be affected. Not only will the fruit-setting rate be low and the fruit prone to deformities, but the coloring will also be poor, the sugar content will drop, and the taste will be bland, ...

Rational fertilization is the key to improving the efficiency of fertilizer savings and use
During the growth of crops, one of the most commonly used measures by farmers to increase yields is to apply more fertilizer. As the farming proverb says: "A crop is like a flower; it all depends on fertilizer to thrive," and another saying goes: "Clever planting is not as good as effective fertilization." Both show that farmers attach great importance to applying fertilizer when growing crops. When choosing fertilizers, some...

Apply organic fertilizer in moderation, and never apply it blindly in excess.
Composting with microbial agents, compared with traditional composting, has the characteristics of being convenient to ferment, saving labor and time, having low cost, and providing high fertilizer efficiency. The specific method is to use roadsides, field edges and abandoned pits and ponds, add water, urea and microbial agents to wheat and corn straw in a certain proportion, pile them layer by layer, then seal them tightly with soil or mud for decomposition...

Fertilizer is not a case of the more the better; rational fertilization is more important
In a broad sense, China has a history of more than 10 years of slow and controlled release fertilizer production. However, among those currently promoted and applied with relative success are only the urease inhibitor stabilized nitrogen fertilizer from the Shenyang Institute of Applied Ecology, Chinese Academy of Sciences, the fertilizer-coated fertilizer type slow release fertilizer using a patent from the School of Engineering of Zhengzhou University, the slow release rice fertilizer from the Soil and Fertilizer Institute of the Guangdong Academy of Agricultural Sciences, and Shanghai Han...
