What's the difference between organic fertilizer and chemical fertilizer? Can you mix it?

Organic fertilizer is rich in all kinds of organic matter and microorganisms, which has a good effect on improving soil fertility and improving the quality of agricultural products. But at present, it is difficult to popularize organic fertilizer, and most farmers are used to using chemical fertilizer. What is the difference between organic fertilizer and chemical fertilizer? Can it be mixed and used?

1. Many factors affect the use of organic fertilizer

Some farmers in ⑴ say they "can't use it." after applying chemical fertilizer for so many years, their output has gone up, and they don't know how to switch to organic fertilizer.

Some farmers in ⑵ say they "don't want to use it." they compost organic manure, crush, stir, pile up and ferment, which is dirty and smelly, so it takes a lot of work and time, so it's much easier to worry about chemical fertilizer. Just go to the agricultural store and pull a few bags.

Some farmers in ⑶ say "do not dare to use it", the organic fertilizer is not strong enough, the effect is slow, the application cost is high, and the yield may be affected in the short term.

Farmers calculate the "economic account", and agricultural development also calculates the "ecological account". Fertilizer is the "grain" of grain, and only with balanced nutrition can crops thrive. However, at present, on the one hand, the agricultural fertilizer structure is out of balance, heavy chemical fertilizer, light organic fertilizer, China's chemical fertilizer production and consumption are ranked first in the world, the average amount of chemical fertilizer per mu is much higher than the world average. This not only leads to the loss of soil nutrients and serious consolidation, but also brings hidden dangers to the quality and safety of agricultural products. On the other hand, a large number of organic fertilizer resources have not been effectively utilized. The actual utilization rate of all kinds of organic fertilizer resources in China is less than 40%. For example, the total amount of livestock and poultry breeding waste is about 3.8 billion tons, 40% of which has not been effectively treated and utilized, and the annual output of straw is 900 million tons, of which more than 200 million tons are unused. it not only causes agricultural non-point source pollution, but also wastes the "other half" resources in rural areas.

two。 Many efforts are needed to popularize organic fertilizer.

At present, the hard constraints of agricultural resources and environment are tightening, so it is imperative to adjust the mode of production. The No. 1 document of the CPC Central Committee pointed out that we will further promote the action of zero growth in chemical fertilizers, carry out pilot projects to replace chemical fertilizers with organic fertilizers, and promote agricultural cost savings and efficiency. The Ministry of Agriculture also proposes to achieve this goal by 2020. It is urgent to popularize and apply organic fertilizer.

It is very important for enterprises to promote organic fertilizer in ⑴.

Although the market potential of organic fertilizer is huge, many production enterprises are small in scale and single in product structure. Compared with chemical fertilizer products, their market competitiveness is weak. This requires organic fertilizer enterprises to practice their internal skills, improve technology and equipment, improve quality, unify product standards, and cultivate well-known fertilizer brands. For example, some enterprises explore the rational combination of organic fertilizer and chemical fertilizer compound products to make up for the shortcomings of slow results. At the same time, the government should strengthen policy support and introduce preferential policies in land use, processing and transportation, so as to help enterprises grow rapidly. In view of the technical difficulties existing in the production and use of organic fertilizer, scientific research and teaching units are organized to jointly tackle key technologies.

Farmers have to accept ⑵ to popularize organic fertilizer.

Only when farmers see the real benefits can they sincerely accept new things. The new type of business subject has the ability, technology and demand, so it should give full play to its "leading goose" role, and the capable person should try first and explore the experience that can be popularized. In view of the problem of "hollowing out" in rural areas, the government can purchase services and give full play to the role of social service organizations. Formulate technical norms and standards and strengthen guidance and services to farmers.

⑶ should speed up the promotion and application of organic fertilizer, make efforts at both ends of supply and demand, and pick up the "other half" resources in rural areas, so as to make the rural environment more beautiful and give more stamina to agricultural production.

3. The difference between organic fertilizer and chemical fertilizer

⑴ organic fertilizer contains a lot of organic matter, which has obvious effect of improving soil and fertilizing. Chemical fertilizer can only provide inorganic nutrients. Long-term use has a negative impact on the soil, and the soil is becoming more and more greedy.

⑵ organic fertilizer has low nutrient content and needs a lot of depth, while chemical fertilizer has high nutrient content and less use.

The fertilizer effect of ⑶ organic fertilizer is long, while that of chemical fertilizer is short and fierce. It is easy to cause nutrient loss.

⑷ organic fertilizer contains a large number of beneficial microorganisms, which can promote the process of biological transformation in soil, improve soil fertility continuously, and chemical fertilizer inhibits the activity of microorganisms, resulting in the decline of soil automatic regulation ability.

4. Benefits of mixed application

⑴ chemical fertilizer has high nutrient content, fast fertilizer effect, but short duration and single nutrient, while organic fertilizer is just the opposite. The mixed use of organic fertilizer and chemical fertilizer can learn from each other to meet the nutrient needs of crops in each growth period.

After ⑵ fertilizer was applied to the soil, some nutrients were absorbed or fixed by the soil, which reduced the availability of nutrients. The mixed application with agricultural fertilizer can reduce the contact surface between chemical fertilizer and soil, reduce the probability of chemical fertilizer being fixed by soil, and improve the effectiveness of nutrients.

⑶ generally has high solubility of chemical fertilizer, which causes high osmotic pressure to the soil, affects the absorption of nutrients and water by crops, and increases the chance of nutrient loss. If mixed with organic fertilizer, it can overcome this malpractice and promote the absorption of nutrients and water by crops.

⑷ if acidic chemical fertilizer is applied only in alkaline soil, after ammonium is absorbed by plants, the remaining acid radical combines with hydrogen ions in soil to form acid, which will lead to acidity enhancement and soil hardening. If mixed with organic fertilizer, it can improve the buffering capacity of the soil, effectively adjust the acidity and alkalinity, so that the acidity of the soil can not increase.

⑸ because organic fertilizer is the energy for microbial life, and chemical fertilizer is the inorganic nutrition for the growth and development of microorganisms. The mixed use of the two can promote the vitality of microorganisms, and then promote the decomposition of organic fertilizer. The activities of soil microorganisms can also produce vitamins, biotin, nicotinic acid, etc., increase soil nutrients, improve soil vitality, and promote crop growth.

At present, for organic fertilizer, farmers do not know how to use it, do not want to use it, and dare not use it, which has become a bottleneck restricting the use of organic fertilizer. In the promotion and application, it is difficult to develop both supply and demand, and it has also become an important factor restricting the development of organic fertilizer. In the past, every household used human and animal manure to make farm manure and straw to compost grass, but now, in many rural areas, organic fertilizer is hard to find. As we all know, we have only used chemical fertilizers for a long time, which has caused many problems in the soil at present. The seriousness has even endangered our living environment. At present, China strongly advocates the application of organic fertilizer, that is, fertilization should be carried out together with organic fertilizer and inorganic fertilizer. If you're not used to switching to organic fertilizer, try mixing organic fertilizer with chemical fertilizer.
