What's good about organic fertilizer?

1. Compared with chemical fertilizer
In China, for many years, due to the long-term application of chemical fertilizer, the shortage of organic fertilizer and the imbalance of various nutrient ratios, the ecological environment of farmland, the physical and chemical properties of soil and the microbial flora of soil have been damaged to varying degrees, which to a certain extent affects the safety of agricultural products. The long-term use of chemical fertilizer has resulted in the decline of fertilizer efficiency, low utilization rate and soil hardening. The above disadvantages can be avoided by using organic fertilizer
2. Compared with farmyard manure
What is the difference between the commercial fertilizer production process and the organic fertilizer made by farmers themselves? Generally speaking, there are many defects in the organic fertilizer that has not been harmlessly treated by the organic fertilizer machine: first, it contains more salt, which is easy to salinize the soil, the emergence of seedlings is not orderly, and the rooting is slow; second, it brings more bacteria and eggs, which is easy to cause diseases and insect pests; third, the content is unstable, which can not guarantee enough nutrients, and it is easy to burn seedlings and roots.
The following problems can also be avoided by increasing the proportion of organic fertilizer application in China: first, agricultural wastes accumulate in large quantities, nutrient loss and environmental pollution. According to the survey data of more than 10 provinces, the share of agricultural waste in pollutants reaches 35% - 40%. Second, the soil and crops are seriously deficient in potassium, which makes the soil fertility decline seriously. Third, the use of chemical fertilizer increased, the utilization rate decreased, the cost of agricultural products increased, the income of farmers decreased, and the sustainable development of agriculture was affected.
Because of the higher level of agricultural modernization, more and more attention has been paid to organic food. What we attach importance to is ecological agriculture. Because only ecological agriculture can produce ecological food. In this regard, the state has invested a lot of support in both the strength of national policy support and the actual actions. Now we know that the wide application of organic fertilizer is the best explanation. It can be said that with the development of technology, organic fertilizer will gradually replace other fertilizers and become a necessary fertilizer for crop growth.
