How to reasonably match organic fertilizer, inorganic fertilizer and biological bacterial fertilizer?

One flower of a crop depends entirely on fertilizer.” If you want your crops to grow well, the choice of fertilizer is the key. However, there are so many choices of fertilizers, such as organic fertilizer, inorganic fertilizer, and biological bacterial fertilizer. Which one is most suitable for your crop growth? What is the difference between the three fertilizers, and how can they be properly matched to maximize their effect?

● Organic fertilizer

Mainly derived from plants and (or) animals, carbonaceous materials that are applied to the soil to provide plant nutrition as their main function. It is processed from biological materials, animal and plant wastes, and plant residues to eliminate toxic and harmful substances, and is rich in a large number of beneficial substances, including: a variety of organic acids, peptides, and rich in nitrogen, phosphorus, and potassium. nutrient elements.

It can not only provide comprehensive nutrition for crops, but also has a long fertilizer effect. It can increase and renew soil organic matter, promote microbial reproduction, and improve the physical and chemical properties and biological activity of soil. It is the main nutrient for green food production.

● Inorganic fertilizer

Inorganic fertilizers are mineral fertilizers, which refer to fertilizers produced by chemical synthesis methods, also called chemical fertilizers, or chemical fertilizers for short. Inorganic fertilizers include nitrogen, phosphorus, potassium, compound fertilizers, etc.

It has the characteristics of simple composition, high content of active ingredients, easy to dissolve in water, fast decomposition, and easy to be absorbed by roots, so it is called "quick-acting fertilizer".

● Biological bacterial fertilizer

Biological bacterial fertilizer is a product in which the life activities of microorganisms cause crops to obtain specific fertilizer effects, and it is a kind of fertilizer used in agricultural production. The types of beneficial microorganisms in microbial fertilizers and whether their life activities are vigorous are the basis of their effectiveness, unlike other fertilizers, which are based on the form and amount of major elements such as nitrogen, phosphorus, and potassium.

Because microbial fertilizer is a live preparation, its fertilizer efficiency is closely related to the number and strength of live bacteria and the surrounding environmental conditions, including temperature, moisture, pH, nutrient conditions and the rejection of indigenous microorganisms originally living in the soil.

Advantages and disadvantages of three fertilizers

fertilizer

The advantages are high nutrient content, fast fertilizer efficiency and significant yield increase effect.

The disadvantage is that the nutrient is relatively single, and it usually requires several fertilizers to be applied together; the nutrient release rate is fast, and the vertical balance supply capacity is poor; it is easy to be lost through volatilization, leaching, fixation, etc., and the fertilizer utilization rate is not high; acid, alkali, and salt. Intense, improper application, not only is not good for plant growth, but also deteriorates the soil and reduces soil fertility.

Organic Fertilizer

The advantage is that it is rich in organic matter and a variety of nutrients needed by plants. Organic fertilizer is also a very good soil improvement and soil fertility fertilizer. It has good effects on improving soil structure, increasing soil nutrient capacity, enhancing soil fertilizer and water retention capacity, regulating soil pH, promoting soil microbial activity, and improving soil nutrient availability. effect.

The disadvantage is that the nutrient concentration is low and the fertilizer supply is slow, so the yield increase effect is not as significant as that of chemical fertilizers.

biological bacterial fertilizer

The advantage is that it can activate the fixed nutrient elements in the soil, stimulate the growth and absorption of the root system, and reduce the amount of fertilization of the corresponding nutrient elements.

The disadvantage is that it does not contain any nutrients and cannot supply nutrients to crops for a long time. Since bacterial fertilizers are composed of live bacteria, direct sunlight and mixed application with pesticides are usually avoided, and the requirements for environmental conditions such as soil temperature, humidity, pH, and organic matter content are also stricter.

The combined application effect of chemical fertilizers, organic fertilizers and biological bacterial fertilizers is better than that of single application. However, in order to achieve the best fertilization effect, the following issues should be paid attention to when cooperating with the application.

Pay attention to the time of application

The effect of organic fertilizer is slow, so it should be applied early. Generally, it should be applied at one time before sowing or before planting. It is best to decompose before use. The effect of topdressing in the later stage is not as obvious as that of base fertilizer.

The chemical fertilizer is effective, and it should be applied about a week in advance when it is used as a base fertilizer. When the top-dressing fertilizer is applied, it should be applied before the critical period of crop nutrition or the peak period of nutrient absorption to meet its needs.

Bio-bacterial fertilizer can only play the role of bacteriostasis and bacteriostasis after being multiplied in the soil. Therefore, it should be applied early before planting, so that it has time to multiply and grow. It can be applied to the soil together with the organic fertilizer, or before the planting. Or point application when planting.

Pay attention to the dosage

Different crops have different growth periods and require different amounts of fertilizer, so they should not be applied more or less. Fertilization should be carried out according to the different fertilizer ratios of crops, and at the same time, attention should be paid to the content of nutrients in the soil. It is best to carry out a soil test, and follow the soil test and formula fertilization recommendations.
