Due to soil selection. For soils with slightly alkaline, low organic matter content and lack of available nitrogen and phosphorus, acidic compound fertilizers, such as monoammonium phosphate or humic acid NPK fertilizers, and N and P compound fertilizers, should be used. For acidic soils, For soils with low organic matter content, alkaline compound fertilizers or organic compound fertilizers should be used. For phosphorus-rich or potassium-rich soils, targeted binary compound fertilizers can be used. Due to crop selection. General field crops use nitrogen-phosphorus compound fertilizers, wheat or high-yield grain fields, should use nitrogen, phosphorus and potassium ternary compound fertilizer; wheat, rice and other densely planted crops, suitable for use with powdered compound fertilizer; sparsely planted crops such as corn should use granules Compound fertilizers; vegetables, especially fruit and vegetable and root vegetables and fruit trees and other economic crops require more potassium, should use high potassium, low nitrogen NPK fertilizer, not only increase production but also help improve crop quality. In addition, there are two kinds of potassium in compound fertilizers, one is potassium chloride and the other is potassium sulfate. Potassium chloride must not be applied to bogey crops such as grapes, sweet potatoes, potatoes, tobacco, etc. Where there is no "S" symbol on the compound fertilizer bag, the potassium is potassium chloride. Due to the method of application. In order to increase the fertilizer efficiency of compound fertilizers, different dosage forms of compound fertilizers should be selected for different application methods. For the application of basal fertilizer, granular compound fertilizer must be used, and the higher the hardness of the particles, the better, in order to facilitate the extension of fertilizer efficiency, but also to use compound fertilizer in the compound fertilizer made of ammonium nitrogen, in order to improve the nitrogen The utilization rate. For top-dressing applications, powdered compound fertilizers should be applied in order to speed up fertilizer efficiency, and it should be noted that the content of water-soluble phosphorus in compound fertilizers should be greater than 40%, and nitrogen is composed of ammonium nitrogen and nitrate nitrogen. The compound fertilizer is suitable.
Chemical intermediate, which is used to make dyes, pesticides, medicine, resins, auxiliaries, plasticizers, etc. from coal tar or petroleum products as Chemical Materials. In China, raw materials and intermediates for the production of 11 categories of fine chemicals are called chemical intermediates. Fine chemicals are classified into 11 categories, including pesticides, dyes, coatings, pigments, reagents and high purity substances, information chemicals, food and feed additives, adhesives, catalysts and various additives, chemicals and daily chemicals, and functional polymers in polymer. In China, raw materials and intermediates for the production of the above 11 categories of fine chemicals are called chemical intermediates.
The main chemical intermediates are:The main chemical intermediates are: 2 - Chloro - 2 - Methylpropane, Lithium Amide, Cyclopentyl Chloride, 4 - Allylanisole Bromocyclopentane.We can do Amino Acid subpackage, filling Healthcare Products in capsules and tablets to meet all your needs.

Select compound fertilizers for attention
Compound fertilizer has the advantages of high nutrient content, less accessory components, and good physical properties. It plays an important role in balancing fertilization, improving fertilizer utilization, and promoting high and stable yields of crops. However, it also has some shortcomings. For example, its nutrient ratio is always fixed, and the types of nutrients, quantities, and proportions required for different soils and crops are diverse. Therefore, attention should be paid to the application.
