A contest of fertilizer and fertilizer!

Fertilizer:

1, fertilizer containing no organic matter, humus, so heavy use of chemical fertilizers, soil due to the lack of organic matter and humus, the soil granular structure destroyed, soil harden and farmers plant production.

2, low utilization rate of fertilizer, nitrogen fertilizer because of volatile, erosion, utilization rate is only 30% 50%, the utilization rate of phosphate was 10% 25%, because of the phosphoric acid chemical activity of root and lively, plowing soil after most of the phosphorus with Zn2 + from the soil, magnesium 2 +, Ca2 +, Fe3 +, Al3 + cations form difficult soluble phosphate fertilizer, etc.Potassium is only about 50% utilization.

3. Heavy use of fertilizers has greatly reduced the quality of fruits and vegetables.Because the crops not only need NPK, at the same time also need many trace elements such as zinc, selenium, calcium iron and fertilizer general component is single, so long-term use of chemical fertilizer will lead to soil nutrients contained in a single, easy to make crop nutrition disorders, resulting in crop synthetic internal transformation, inevitably led to the decrease of the quality of crops, the melon is not sweet, food is not sweet.

4. Harmful to human health.A large amount of chemical fertilizer is used to make the nitrate content in vegetables exceed the limit, and the combination of nitrite and amine compounds to form N- nitrite base compound is a strong carcinogen.

5. The abundant use of chemical fertilizer also causes the beneficial bacteria of soil and the mass death of earthworms.

6. Long-term inefficient use of fertilizers often results in excessive accumulation of certain elements in the soil and changes in soil physical and chemical properties and environmental pollution.

The more you use chemical fertilizer, the more you use it, the more you rely on it, the more you rely on it.

Advantages of biological fertilizer:

1. Improved soil

(1) through the proliferation of beneficial bacteria, a large number of beneficial bacteria have formed an advantageous population around the roots of plants, which inhibits the life activities of other harmful bacteria.

(2) the rapid decomposition of soil organic matter, promote the formation of soil aggregate, and through the beneficial bacteria activity can loose soil, soil to protecting fertilizer, fertilizer, water, water supply and air permeability are well adjusted.

(3) to decompose pesticide residues in soil to avoid pesticide residues in the next season.The plant growth process is also decomposed by harmful substances emitted from the root system.

2. Nitrogen fixation, phosphorus removal and potassium removal.

Part to be able to use the nitrogen in the air, through the beneficial bacteria growth metabolism enzyme and acid, can be difficult soluble phosphate, potash fertilizer in the soil, the soil difficult soluble phosphate 95%, difficult soluble potassium 98%) decomposition, becoming the plants can absorb under phosphorus.Therefore, the utilization rate of fertilizer can be greatly improved, thus reducing the application of fertilizer.'

3. Improve crop quality.

Phosphate-solubilizing, releasing, at the same time, leads to the release of trace elements in the soil, is used by the crop, at the same time beneficial bacteria metabolism substance required to produce a variety of plants, small molecules such as amino acids, growth stimulating substances, vitamins, etc.

4. To achieve the effect of biological control, the irrigation can inhibit the bacteria in soil and spray onto the leaf surface to prevent the invasion of diseases.

5. Promote precocity and prolongation of crops.Due to the improvement of soil physical and chemical properties, soil nutrient is rich and balanced, the fertilizer in soil can be better absorbed by the crops, so it can promote the early maturity of crops and extend the harvest time.

6, and organic fertilizer, to continuously improve soil, 2 to 3 years to make a soil can reach the standard in the production of organic crops, and because of the beneficial bacteria can quickly decompose organic matter for crop absorption, so overcome the characteristics of applied organic fertilizer, slow, low single organic fertilizer production.
