Compound fertilizer purchase tips

One must understand the types and characteristics of chemical fertilizers on the market. Fertilizers are no longer the oldest type (urea, diammonium, potash fertilizer) in the past. In recent years, many compound fertilizers, special fertilizers, and formulated fertilizers have been added to the market. First of all, we need to understand the content and function of NPK, trace elements in various fertilizers, and then choose the type and quantity of chemical fertilizer according to our actual needs.

Second, fertilizers should be purchased based on soil fertility. To promote soil testing and formula fertilization, we must first master the soil types, nitrogen, phosphorus and potassium contents, and organic matter content of our own land. We must adjust conditions to local conditions so that we can make up for what we lack and how much we can make up. We should use chemical fertilizers scientifically and rationally. Reduce investment, reduce pollution, and improve the quality of agricultural products.

Third, according to different crops need fertilizer law to buy fertilizer. Corn, soybeans, rice, vegetables, melons and fruits need different kinds and quantities of fertilizers in their growth and development.

Fourth, we must go to the regular manufacturers and distribution units to purchase fertilizer. When a farmer's friend purchases chemical fertilizer, he must go to a factory with good reputation and licenses and a distributor to purchase chemical fertilizer. To leave receipts and related tickets for the purchase of chemical fertilizers, you can vouch for claims in the event of a problem.

Fifth, we must purchase product labels and three kinds of chemical fertilizers. When purchasing fertilizer, it is necessary to see the complete product identification and whether the “three licenses” (production license, production standard license, and fertilizer promotion license) are complete. After purchase, they must ask for purchase vouchers and credit cards.

Sixth, it is necessary to prevent false advertising misleading. Some of the compound fertilizers, compound fertilizers, organic-inorganic fertilizers, multi-element compound fertilizers, organic biological fertilizers, etc., whose advertisements often exaggerate the effects and effects, must be guarded against in the process of purchase and use.

Seventh, we must consult agricultural technicians and purchase fertilizers. When you encounter problems, you can consult with agricultural technicians and fertilizer experts. Ask them to help you as a consultant and get your ideas. Don't buy your own fat blindly.

Look at the packaging. The outer packaging is a woven bag, the inner packaging is a plastic bag, the packaging bag is machine-stitched, and the seams should be neat and consistent.

Look at the logo. The State requires that the packaging should be marked with the trademark, fertilizer name, manufacturer, fertilizer composition, product net weight and standard code.

Look at the colors. Fertilizer particles have good luster, uniform color and bright color, and are dark and light.

Look at the shape. Uniform size, no powder, loose dry, non-sticky, no agglomeration.

Look at the hardness. The palm of the hand puts on the fat and twists it twice. It is not broken and is good.

See water solubility. Take a small amount of nitrogen and potassium fertilizer into the water and stir for 5 minutes. It can be completely dissolved and is not completely dissolved. Diammonium phosphate dissolves in water, but the melting time is longer.

Vitamins are organic compounds and vital nutrients that an organism requires in limited amounts. An organic chemical compound (or related set of compounds) is called a vitamin when the organism cannot synthesize the compound in sufficient quantities, and it must be obtained through the diet.

Your body needs them to work properly, so you grow and develop just like you should. They are essential for the normal growth and development of a multicellular organism. Once growth and development are completed, vitamins remain essential nutrients for the healthy maintenance of the cells, tissues, and organs that make up a multicellular organism; they also enable a multicellular life form to efficiently use chemical energy provided by food it eats, and to help process the proteins, carbohydrates, and fats required for respiration.
