Microbial fertilizer is more expensive than ordinary fertilizer, but should the money be spent or not?

With the development of science and technology, the types of fertilizers are also constantly changing, from the previous single chemical element fertilizer to the current multi-element and microbial fertilizer.

In recent years, some farmers who grow cash crops have indeed realized that microbial fertilizer can improve soil fertility and improve yield in practice. What is the principle of this? The current microbial fertilizer prices are indeed higher than organic fertilizer and inorganic fertilizer prices, so why are some people still using it? Should this money be spent?

Before understanding the reasons, Xiao Bian will first analyze the evolution of China's soil environment, because the soil environment is the object of direct contact between crops and fertilizers, and its changes directly affect crop growth and fertilizer utilization rate.

Evolution of soil macroenvironment

Since the 1970s and 1980s, agricultural land in our country has been heavily used with single chemical element fertilizers, such as ammonium bicarbonate, thiamine, diamine, urea and other macroelement fertilizers. These fertilizers are absorbed quickly and increase yields. However, this also caused the deterioration of the soil environment.

Due to the large amount of chemical fertilizer input, a large number of nitrate, sulfate, hydrogen sulfate and other acid radical ions gradually accumulated in the soil, which gradually reduced the pH value of the soil and tended to acidify, resulting in soil hardness and hardening. The land will be waterlogged and cracked on sunny days.

It is mainly reflected in the following aspects:

Crops grow slowly and become sub-healthy

Each crop has a suitable pH range, and most crops grow in slightly acidic and alkaline environments. However, the existence of a large number of acid radical ions makes the soil acidity larger, causing the root system of crops to be unable to absorb and secrete substances normally, resulting in root nutrition not keeping up.

Root is the root of crop growth, and its lack of nutrients directly affects the growth of the whole crop. Even, it can accelerate the weathering of primary and secondary minerals containing aluminum in the soil and release a large amount of aluminum ions to form aluminum compounds that crops can absorb, and crops that absorb aluminum for a long time and excessively will be poisoned or even die.

Low fertilizer utilization rate, high investment

After years of chemical fertilizer input, soil minerals themselves fixed a large number of phosphorus, potassium and other nutrients, reaching a saturated state. If fertilizer is applied again, it will not be adsorbed by the soil, but will be leached away by water, which will further cause acidification of the soil environment. Soil acidification, crop roots can not absorb nutrients and grow poorly, farmers often increase fertilizer input, which will increase the concentration of soil acid radical ions, resulting in a vicious circle.

Easy to breed germs and produce diseases

Acidification of soil will result in the decline of reproductive ability and living ability of some beneficial microorganisms, even death. On the contrary, some harmful microorganisms will take the opportunity to multiply in large numbers, and then infect the roots of crops to spread throughout the body. For example, root rot of some crops is caused by the invasion of harmful microorganisms.

What role can microbial fertilizer play?

The efficacy of microbial fertilizer is mainly related to the source and effectiveness of nutrient elements, or related to crop absorption of nutrients, water and disease resistance, summarized in the following aspects:

improving soil fertility

This is one of the main effects of microbial fertilizer. For example, all kinds of spontaneous and symbiotic nitrogen-fixing microorganisms can increase the nitrogen source in the soil; the application of various phosphorus-dissolving and potassium-dissolving microorganisms can decompose the insoluble phosphorus and potassium in the soil, so that they can be absorbed and utilized by crops.

After microbial fertilizer is applied to the soil, it can rapidly reproduce and form a strong probiotics group, fundamentally improve the ecological structure of the soil and the surrounding roots, make the soil hardened by chemical fertilizer for many years loose and breathable, absorb nitrogen in the air and form "ecological nitrogen fertilizer", activate the ineffective dead phosphorus and potassium deposited in the soil for many years, and let the roots of crops absorb it.

enhanced stress resistance

Microbial fertilizer can reduce crop diseases besides increasing yield and income of traditional fertilizer. There are three main reasons for this:

One is the growth and reproduction of beneficial microorganisms in fertilizers, forming dominant populations in crop rhizosphere soil microecosystems, inhibiting the growth and reproduction of other harmful microorganisms, and even antagonizing some harmful pathogens, reducing the harm opportunities of harmful microorganisms.

The other is that beneficial microorganisms secrete various metabolites to crop rhizosphere soil microecosystem during their growth and reproduction, which can stimulate crop growth and improve crop resistance to adverse environments.

Third, when crops suffer from diseases, freezing damage, drought, senescence and other stresses, microbial fertilizer is applied, and the strains contained in it can induce crops to produce superoxide dismutase and eliminate free radicals generated by stress, thus improving crop resistance and alleviating diseases.

Improve quality, early maturity and high yield

Microbial fertilizer can stimulate the fixed potassium, calcium, zinc and other trace nutrients in the soil, these elements can supply crops, many of the soil beneficial microorganisms can also produce plant hormones, stimulate and regulate crop growth, so that crop growth robust, nutritional status has been improved. Generally, it can increase the yield of economic crops by more than 30%, and the yield of field crops by 7~10% or more.

Speaking of which, do you think this money should be spent?

If you want high and stable yields, investment is a must. Instead of blindly investing, it is better to choose rationally. It is the last word to spend money on the cutting edge!

microbial fertilizer

1. Supplement soil beneficial bacteria, deeply loosen pure soil, break hardening, quickly promote the formation of aggregate structure, make soil full of vitality, reshape healthy and fertile farmland.

2.80 Multiple beneficial bacteria stack, promote root system development, mycorrhizal symbiosis, nitrogen fixation, phosphorus and potassium dissolution significantly improve fertilizer utilization rate, increase soil organic matter, supplement medium and trace elements and various growth-promoting substances, balance nutrient absorption, and enhance crop resistance.

3. Carrier-type large beneficial bacteria cooperate with each other to inhibit harmful bacteria, eggs, eliminate toxins, degrade heavy metals, decompose residues, adjust acid and reduce alkali, cultivate healthy soil, and achieve the purpose of thoroughly preventing and controlling diseases and insect pests.

4. Biological control disease, solve crop obstacles, effectively control all kinds of fruit rot disease, root rot, virus disease, deficiency disease, replanting disease and peach gum, kiwi canker disease; solve the problem of vegetable replanting, is a good helper for your planting.
