Bio-organic compound fertilizer is good for high efficiency

Experiments have shown that bio-organic compound fertilizers are effective in improving soil structure, improving soil properties, inhibiting soil-borne diseases, and increasing crop yields. However, in actual production, the degree of popularization and application is not satisfactory. The reflection is also very different. Technology-savvy farmers are very welcome, thinking that bio-organic compound fertilizers are rich in nutrients and they are labor- and time-saving, but at the same time, they reflect that bio-organic compound fertilizer products have been performing well for the first two years, and their effects have become worse; Bio-organic compound fertilizers have a rough packaging and are not resistant to storage and transportation; many bio-organic fertilizers contain tainted nutrient content on the packaging and are only labeled with the total amount of nitrogen, phosphorus and potassium, and have no active ingredient content or no chlorine content. The author's investigation also found that many bio-organic compound fertilizers have a method of drawing up high total nutrient content, adding organic matter, humic acid, and trace elements as total nutrient content to raise prices, and that manufacturers often set corporate standards. Lower than the mandatory standards set by the state.

In view of the above situation, according to the author's many years of guiding production experience, the plant grower should be reminded to do the following work when selecting bio-organic compound fertilizers, so as to maximize the bio-organic compound fertilizer fertilizer effect.

First of all, it is necessary to clarify the concept of different fertilizers and ensure the selection of products. Fertilizers made of chemical compounds formed by chemical reactions are called compound fertilizers. Fertilizers made by mixing physical and mechanical materials are called compound fertilizers. Compound fertilizer and compound fertilizer nutrient content is generally based on the three elements of nitrogen, phosphorus and potassium. Bio-organic compound (mixed) fertilizers are made from organic materials and then mixed with inorganic fertilizers. The organic matter, NPK, and functional microorganisms should have different labels. Although they have their own functions, they cannot be added to the total nutrient content.

Second, it is necessary to see from the packaging the true and false fertilizer. Some farmers only look for the color of the packaging to look good, while ignoring the completeness of the compound fertilizer production method. The purchase of bio-organic compound fertilizer also depends on the production license, business license, and standard certificate on the packaging. It depends on the product name, manufacturer's name, origin, and date of manufacture. At the same time, we do not forgot to request an invoice.

Third, we must clarify the categories from the nutrient content, and then select different types of fertilizer according to different soils and different crops. Including the effective content of nitrogen, phosphorus and potassium in products, the content of medium and trace elements and organic matter, humic acid, and whether it contains chloride.

Fourth, we must distinguish the quality from the intuitive one. The high-quality compound fertilizer has good consistency, no hard block, white crystals are visible on the surface of the particles after storage, and small red potassium fertilizer particles are also accompanied; the fertilizer particles have the feeling of adhesion and moistness when being squeezed; the solubility is good when soaked in water; a small amount of granular fertilizer is placed on Iron baking, the thicker the ammonia, the more yellow the flame, indicating that the higher the content of potassium and potassium. On the contrary, the quality is not fully met.

Fifth, the application should be skillful. Different types of bio-organic compound fertilizers are rich in organic matter, promote the application of basal fertilizer, and apply a certain amount of potassium sulfate compound fertilizer to make the fertilizer release steadily over a long period of time. When applying fertilizer, 25 kg of ammonium bicarbonate should be applied per acre to combine the speed of fertilizer supply. When applied, the field should have better sensation, and should be drought-fighted immediately after application. If conditions permit, it is best to deepen or deepen.
