Organic fertilizer use precautions! Organic fertilizer is not used as much as possible

Organic fertilizer use precautions! Organic fertilizer is not used as much as possible. Organic fertilizer refers to a kind of fertilizer that contains organic matter, can provide a variety of inorganic nutrients and organic nutrients of crops, and can fertilize and improve soil. Most of them are farmed locally and are self-contained.

Direct application of raw manure. For this problem, we have already sent related articles to understand - (Warning: the decomposing is not complete, the feces, the rotten is completely fat). Therefore, it is strictly forbidden to directly drop the manure. At this time, the factory-processed commercial organic fertilizer can be purchased. The factory has been fermented and sterilized for farmers, and can be used directly after the farmers buy it.

The hazard of excessive application of organic fertilizers. The low nutrient content of organic fertilizers has no obvious effect on crop growth. Unlike fertilizers, which are easy to burn, and the organic matter accumulated in the soil has obvious effects on soil improvement, some people mistakenly believe that the more organic fertilizers are used, the better.

The actual excessive application of organic fertilizers, like chemical fertilizers, can also cause harm. The hazards are mainly manifested in the following points. Excessive application of organic fertilizer results in burning of the seedlings. A large amount of organic fertilizer is applied, resulting in a large accumulation of nutrients such as phosphorus and potassium in the soil, resulting in imbalance of soil nutrients. A large amount of organic fertilizer is applied, and nitrate ions in the soil accumulate, causing the nitrate in the crop to exceed the standard.

Organic and inorganic cooperation is not enough. Organic fertilizers have comprehensive nutrients, but their content is low. In order to fully meet the demand for nutrients in crops, in order to fully meet the demand for nutrients, organic fertilizers should be supplemented with appropriate fertilizers. Some manufacturers exaggerate the role of organic fertilizers, only organic fertilizers, crop growth can not meet the nutrient demand at the critical moment, leading to crop yield reduction.

I like organic fertilizers that are used in large quantities and at low prices. There are many kinds of organic fertilizers, and the quality of organic fertilizers processed by different raw materials and different methods is very different: for example, organic fertilizers that farmers naturally pile up in the field, although the pathogens have been killed after a long period of rot, but Long-term fermentation and processing, as well as the leaching of rain, the nutrients inside have lost a large part.

In addition, in the process of processing, it is inevitable to bring some impurities such as soil, and there is no drying process, and the moisture content in the fertilizer is high. Therefore, although such organic fertilizers are bulky and heavy, they do not provide much organic matter and nutrients to the soil. Taking chicken manure as an example, fresh manure has a high water content, generally 70% water content, dry matter only accounts for a small part, most of which is water, so about 3.5m3 of fresh manure can process 1 ton of water and less than 20% of dry organic fertilizer.

Due to the increasing level of modernization of agricultural agriculture, organic food has received more and more attention. The emphasis is on ecological agriculture. Because only ecological agriculture can produce ecological food.

In this respect, the state has invested a lot of support in both the strength of national policy support and the actual actions. The wide application of organic fertilizers we know now is the best illustration. It can be said that organic fertilizer will gradually replace other fertilizers and become an essential fertilizer for crop growth.

In the production of organic fertilizer, it has received strong support from many experts. At the same time, on the equipment, it also received strong support from the state. In many places, there are specialized equipment and production lines for the production of organic fertilizers in order to produce better organic fertilizers. In terms of policy support, many local governments have given a lot of help.

In particular, it has received great support in the use of waste and disposal of some discarded daily necessities, because on the one hand, it not only treats domestic garbage, but also reduces environmental pollution, and on the other hand, it turns waste into treasure, and produces valuable. Organic fertilizer.

In many places, this is a very good move. Therefore, many local governments will give strong support to the production and use of organic fertilizers, and even some economic subsidies to encourage people to use organic fertilizer.

It can be said that it is the widespread use of organic fertilizer that can gradually transform our agriculture into pollution-free agriculture, so that more organic food, fruits and vegetables can be brought to our table.

With the development of the economy and the acceleration of urbanization, the urban population has proliferated and the city's pollutants are increasing. In fact, urban pollutants can be turned into organic fertilizer through treatment.

Organic fertilizer is essential for organic agriculture and ecological agriculture. It can improve soil properties, improve soil fertility, increase the yield and quality of agricultural products, and curb environmental pollution. It is recommended that the government increase investment and design the classification and treatment of urban pollutants in the planning of urban construction, and use this as a new type of industry to treat urban pollutants into organic fertilizers with low price and convenient transportation, turning waste into treasure. Agricultural services.

Problems that organic fertilizers need to pay attention to during fertilization

1. First, one thing that needs to be understood first, although organic fertilizer works well, it is not omnipotent. The nutrients contained in organic fertilizers are not balanced and cannot meet the needs of high yield and quality of crops. Therefore, when the organic fertilizer is applied, the fertilizer can be applied as required, and various foliar fertilizers are applied during the growth of the crop.
2. Second, compared with other fertilizers, the decomposition of organic fertilizer is relatively slow, and the fertilizer effect is later. Although it has a full range of nutrient elements, it is low in content and decomposes slowly in the soil. Therefore, experts suggest that the combination of organic fertilizer and chemical fertilizer, the two to learn from each other, to play their respective advantages.
3. Third, in general, before using organic fertilizer, it is best to undergo fermentation treatment. Since many organic fertilizers carry germs, eggs and weed seeds, these are not conducive to the healthy growth of crops, so they can be applied after processing.
4. Fourth, the last point is the precautions for the use of organic fertilizer. The decomposed organic fertilizer should not be mixed with alkaline fertilizer. If it is mixed with alkaline fertilizer, it will cause the evaporation of ammonia and reduce the nutrient content of organic fertilizer, which will lead to nutritional imbalance. At the same time, bio-organic fertilizer contains more organic matter and should not be mixed with nitrate-based ammonia fertilizer.
