Adopt domestic high quality large particle urea

Suitable for long-acting slow control polypeptide urea                                    

Combination of the two, quick effect, slow control, longer fertilizer effect




· Phosphate fertilizer: The best water-soluble, higher effective phosphorus content, more easily absorbed by crops, higher utilization rate。What is water solubility？When we talk about water-soluble phosphorus, that is, phosphorus that plants can directly absorb。The water solubility of Yunfeng diamine we choose is more than 90%, so it contains 20% phosphorus according to the standard, and the diamine used by other manufacturers is 70%, so we calculate that our water-soluble phosphorus is higher than their 4 nutrients here。




· Potassium: Using the world famous brand "German Red Bull", potassium sulfate, potassium chloride, which has low chloride ion content, better crop absorption and higher safety。Where is the comparison between good and bad potassium fertilizer？The chloride ions of natural potassium are less than half that of our domestic potassium。What is a chloride ion？The chloride ion is also called chloride, which he simply means salt。Think about it, the basic PH value of our northeast soil is relatively high, and most of the soil is stained with salt alkali。According to this, you are adding a relatively high salt content of fertilizer to it, do you think he can be good？
