Choose so much fertilizer, organic fertilizer, inorganic fertilizer, bio-bacterial manure, which is most suitable for your crops, and what is the difference between the three kinds of fertilizer and that how to reasonable collocation can plays the biggest role?
Organic fertilizer
Organic manure is mainly derived from plants and/or animals, and is applied to the soil to provide plant nutrition as its main function of carbon containing materials.By the biological material, plant and animal waste and crop residue processing, eliminates the poisonous and harmful material, rich in a large number of useful substances, including: a variety of organic acids, peptides and including nitrogen, phosphorus and potassium, rich in nutrients.
Not only provide comprehensive nutrition for crops, and long fertilizer effect, can increase and update the soil organic matter, promote microbial breeding, improving soil physical and chemical properties and biological activity, are the main nutrients of green food production.
The inorganic fertilizer
Inorganic fertilizer is mineral fertilizer, which is the fertilizer produced by chemical synthesis method, also called chemical fertilizer, short for fertilizer.Inorganic fertilizer includes nitrogen, phosphorus, potassium, compound fertilizer and so on.It has the characteristics of simple composition, high effective composition, easy to dissolve in water, fast decomposition and easy to be absorbed by root system, so it is called "quick effect fertilizer".
Bio-bacterial manure
Biological fertilizer: a product of microbial life that results in a specific fertilizer effect on crops, and is a kind of fertilizer used in agricultural production.Type of beneficial microorganisms in the microbial fertilizer, whether life activities is the basis of its effectiveness, and unlike other fertilizer is the main element such as nitrogen, phosphorus and potassium in the form of and how much.
Because of microbial fertilizer is live agents, so its effectiveness and the number of living bacterium, the strength and the surrounding environment conditions are closely related, including temperature, moisture content, acidity, nutrient condition and the original life in the middle the soil microbial rejection has certain influence.
Advantages and disadvantages of the three fertilizers.
The inorganic fertilizer
Advantages: high nutrient content, fast fertilizer effect, significant increase effect.
Disadvantages: relatively single nutrient, usually need several fertilizer to cooperate with the application;The nutrient release rate is fast and the vertical balance is poor.Volatilization, leaching, fixation and other means of loss, fertilizer utilization rate is not high;Acid, alkali and salt are strong, not only harmful to plant growth, but also can reduce soil fertility and soil fertility.
Organic fertilizer
Advantages: rich in organic matter and various nutrients required by plants.Organic fertilizer or very good soil improvement, soil fertilizer agent, to improve soil structure, soil nutrient, strengthen soil protecting fertilizer water retention, adjust the soil acidity, enhance soil microbial activity, improve the soil nutrient availability and so on all has the good effect.
Disadvantages: low nutrient concentration, slow fertilizer, so the effect of stimulation is not as significant as fertilizer.
Bio-bacterial manure
Advantages: it can activate the fixed nutrient elements in the soil, stimulate the growth and absorption of the root system, and reduce the fertilizing amount of the corresponding nutrient elements.
Disadvantages: it does not contain any nutrients, nor can it supply nutrients for long periods of time.Due to the composition of bacterial manure, it is usually avoided by direct sunlight and mixed with pesticide, and the environmental conditions such as soil temperature, humidity, ph and organic content are also strict.
Knowing their advantages and disadvantages, we can conclude that the application effect of chemical fertilizer and organic fertilizer and bio-fertilizer is better than that applied alone.However, in order to achieve the optimal fertilization effect, the following problems should be paid attention to.
How to match:
First, notice the application time.
The effect of organic fertilizer is slow, it should be applied in advance, and it is generally used before planting or before planting. It is better to use it before it is used.
The fertilizer will be effective, and the fertilizer should be applied about a week in advance, and the fertilizer should be applied before the critical period of crop nutrition or the peak of the absorption peak to meet the needs of the fertilizer.
In bio-bacterial manure in the soil, multiply to give play to the role of bacteriostasis to bacterium, so want to be in planting earlier in, make its have reproduction growing time, can be applied into the soil with organic fertilizer, can also be before engraftment or planting when the acupuncture point.
Secondly, pay attention to the application method.
Main effect of organic fertilizer is improved soil, nutrients at the same time, generally as basal application into the soil, so want to combine agriculture, soil and fertilizer fully blending, to achieve the purpose of improving soil, soil problem serious when also can be used with sea elf against stimulants, can better improve the soil environment, balanced nutrition, increase the soil granular structure, etc.
In the base fertilizer, because the nutrient in the organic fertilizer is mainly nitrogen, the nitrogen fertilizer with the organic fertilizer can be less applied, can be used 30% as the base fertilizer and 70% as the fertilizer.Phosphate fertilizer and potash fertilizer can be applied in one time, phosphate fertilizer is poor in mobile, and the latter effect is very poor, so phosphate fertilizer should be applied to soil.
The fertilized fertilizer is best used with full soluble fast fertilizer, such as phosphorus and potassium source, which can be quickly absorbed by vegetables after decomposing, which has little effect on soil.
Biobacterial fertilizer can be applied in the fixation point or with organic fertilizer because of its low dosage.In the later stage, the same biological fertilizer can be used multiple times to strengthen the bacteria group, so as to improve the ability of phosphorus and potassium and prevent disease.
Again, pay attention to the dosage.
Different crops have different growth periods, and the amount of fertilizer required is different.Fertilization should be carried out according to the different needs of the crops, and the content of nutrients in the soil should be considered.It is best to carry out a survey of soil, according to the soil formula fertilization recommendations.
