What’s the Classification of Microbial Fertilizers？
Microbial fertilizer refers to a form of organic agent that consists of residing microorganisms and might acquire a particular fertilizer effect in use to growth plant yield or enhance exceptional. Classification of microbial fertilizers:
There are many kinds of microbial fertilizers in China. Up to now, there may be no complete and unified type device. According to the distinctive category requirements, there are several type techniques:
Narrow-scale microbiological fertilizer refers back to the increase of the pastime and supply of plant nutrient elements through the existence activities of microorganisms, thereby growing the yield, this is, the microbiological agent containing the traits of fertilizers. Microbial liquid fertilizer Although those products do now not have vitamins, they have the feature of fertilizers.
Generalized microbial fertilizers: The microbial fertilizers have little or no nutrient supply function, but they've different results, such as stimulating plant increase or antagonizing pathogenic results of sure pathogenic microorganisms, degrading harmful pollution, and many others. It should be known as “microbial instruction” in preference to fertilizer, however now it's miles together called microbial fertilizer, and it's miles registered and registered with the Ministry of Agriculture.
Divided through microbial species
Bacterial fertilizers: nitrogen-fixing micro organism, phosphorus-solubilizing micro organism, and potassium-releasing micro organism.
Fungal fertilizer: This form of fertilizer consists of two kinds of ectomycorrhizal fungi and endophytic mycorrhizal fungi, together with arbuscular mycorrhizal fungi, mycorrhizal fungi, orchid mycorrhizal fungi, and Trichoderma spp.
Actinomycete fertilizers: which include antibiotics;
Algal fertilizers: such as nitrogen-fixing cyanobacteria.
Divided by using features
Phosphorus-solubilizing microbial fertilizers, potassium-liberating microbial fertilizers, and organic rely-decomposing microbial fertilizers, which include legume inoculants and soil phosphorus activators. Microbial fertilizers of the same type also can be fertilizers of various microbial species, microbial liquid fertilizer which include phosphorus-solubilizing bacteria, which can be either bacterial fertilizers or fungal fertilizers because the identical microorganism has unique functions, or various organisms have the equal cause.
Divided via the quantity of microorganisms
They are divided into a unmarried microbial or composite microbial fertilizer.
Single microbial fertilizer: It contains best one type of microbial fertilizer.
Compound microbial fertilizer: a microbial preparation fashioned through a mixture of microorganisms in a specific share. Microorganism + Organic Fertilizer = Biological Organic Fertilizer
Microorganism + Fertilizer = Biological Compound Fertilizer
Microorganism + Organic Fertilizer + Fertilizer = Biological Organic-Inorganic Compound (Compound) Fertilizer
Ministry of Agriculture registered microbial fertilizer kinds.
At present, the Ministry of Agriculture has registered a complete of microbial fertilizer products: nine fungi species: rhizobia, nitrogen-fixing micro organism, phosphorus-solubilizing micro organism, silicate micro organism, mycorrhizal fungi, photosynthetic fungicides, natural material decomposing agents, Compound inoculants and soil repair micro organism.
Two bacterial fertilizer classes: compound organic fertilizers and bio-natural fertilizers. In the dosage form is split into liquid and solid, solids are divided into powder and granules.
Effect VS Problem
Microbial fertilizer application impact
Increase crop yield
The improved fee of various styles of microbial fertilizers was approximately 10%, of which the maximum tremendous was the growth within the production of composite microbial fertilizers, which changed into extra than 20%. Studies have proven that the utility of microbial fertilizers by myself with out natural fertilizers or chemical fertilizers has a extensive impact on potato yield, but microbial fertilizers most effective play a helping function in crop yield growth and cannot be used by myself in place of natural fertilizers and chemical fertilizers.
Improve the best of vegetation
It is an indisputable fact that microbial fertilizers can improve crop fine.
Some microbial fertilizers can nonetheless enhance the satisfactory of plants even though they do now not have a huge increase in manufacturing.
The software of microbial fertilizers can substantially boom the sugar content and diet C content of vegetables at the same time as reducing the nitrate content of veggies. The impact of microbial fertilizers on the pleasant of fruit is likewise apparent.
Reduce pest harm
The experimental outcomes of Zhang Weiwei et al. In 2013 confirmed that microbial fertilizers have a stable manage impact on subject cotton wilt disease and eggplant verticillium wilt sickness, and the ailment index declined.
38.2, and 23.5. Microbiological fertilizers for tobacco can reduce tobacco virus disease, sell tobacco boom, and decrease miscellaneous fuel and irritation. Microbial fertilizers can efficiently lessen the pesticide damage to herbicides from the soil.
Improve soil structure
The long-term use of microbial fertilizers can restore the formation of soil aggregates, and play a function in loosening the soil, eliminating soil compaction, and enhancing soil shape.
According to reviews, soil phosphorus weight loss decreased via zero.1 to 0.3 in soil applied to the black soil of northern China for 3 consecutive years. The loose soil impact may be very widespread. Some studies have also proven that once the utility of microbial fertilizer, due to the proliferation of microorganisms, microbial liquid fertilizer the release of organic rely within the soil is promoted, the bodily and chemical properties of the soil are improved, the soil aggregates are increased, and the soil shape is progressed.
Problems with microbial fertilizers
The supporting gadget isn't always best
At gift, China has no longer but formed a system of agricultural fertilization, advertising and supervision that is conducive to the software of microbial fertilizers. Soybean rhizobial inoculation in advanced nations has turn out to be ordinary farming practices, while the soy bean rhizobium inoculation price in Northeast China is much less than 10%. The software quantity of chemical fertilizers in discipline vegetation along with corn and rice is immoderate, microbial fertilizers and organic fertilizers are not often used, short-term behavior is big, and promotion efforts and coverage guide are inadequate. At the same time, the microbial fertilizer marketplace is mixed, and the country has no longer but set up a complete regulatory gadget and product general for the high-quality supervision of such fertilizers.
Strain purity isn't always excessive, now not centered.
Microbial fertilizers are ecologically adaptable. When applying, specific software strategies and application quantities must be determined primarily based on the neighborhood ecological conditions, crop sorts, soil kinds, and farming methods, and focused traces ought to be screened for fantastically adaptive purposeful lines to reap higher effects. However, the tremendous majority of microbial fertilizer agencies nevertheless use particularly backward cultivar breeding strategies, consisting of separation screening and conventional breeding. It results in negative geographical focused on and bad adaptability of microbial fertilizers. Individual corporations might also even fail to purify and rejuvenate. , resulting in decreased purity of the micro organism, decreased activity, unstable subject results, or fast decline.
The impact of instability
The software effect of microbial fertilizers is suffering from many factors. In addition to the inherent elements together with the sort, content, and purity of the energetic bacteria of the fertilizer, the environmental conditions also are essential elements affecting the effectiveness of the fertilizer, microbial liquid fertilizer including substrate awareness, temperature, humidity, soil pH, etc. The effect of the usage of many microbial fertilizers is a lot one-of-a-kind from the expected one, and there are big variations between plots and years
