Organic fertilizer is an important agricultural fertilizer, which is mainly used in organic matter such as animal and plant residues, manure, municipal garbage, etc., and can be used as fertilizer in farmland after certain treatment and processing. Compared with chemical fertilizers, organic fertilizers have the advantages of comprehensive nutrients, long-lasting fertilizer efficiency, and improved soil structure, so they have been widely used in agricultural production.
So, what agriculture mainly uses organic fertilizers?
First of all, organic agriculture is one of the main areas where organic fertilizers are applied. Organic agriculture is an agricultural production method that follows the laws of nature and ecological principles and coordinates planting and animal husbandry. In organic farming, synthetic fertilizers and pesticides are prohibited, so organic fertilizers have become the main fertilizers**. Through the application of organic fertilizer, organic agriculture can maintain soil fertility and biological activity, improve the yield and quality of crops, and also protect the ecological environment and human health.
Secondly, green agriculture is also one of the important areas for the application of organic fertilizer. Green agriculture is an agricultural production mode that pays attention to ecological environmental protection, resource conservation and utilization, and the quality and safety of agricultural products. In green agriculture, we advocate the use of environmentally friendly fertilizers such as organic fertilizers and reduce the use of chemical fertilizers and pesticides to reduce environmental pollution and harm to the human body. Through the application of organic fertilizer, green agriculture can improve soil structure, improve soil fertility, promote the growth and development of crops, and also increase the nutritional value and taste of agricultural products.
In addition to organic agriculture and green farming, there are some specific crops that also apply organic fertilizer. For example, horticultural crops such as vegetables and fruits, due to their high requirements for soil fertility and environment, the application of organic fertilizer can better meet their growth needs. At the same time, the beneficial microorganisms in organic fertilizer can promote the growth and development of horticultural crops, improving their quality and yield. In addition, some special crops such as tea and Chinese herbal medicine are also mainly applied with organic fertilizer to ensure their quality and purity.
Of course, there are also some problems to be paid attention to in the application of organic fertilizer. First of all, organic fertilizer has a lower nutrient content and slower fertilizer efficiency, so it needs to be applied in advance and in sufficient amounts. Secondly, the quality of organic fertilizer also needs to be paid attention to, and it is necessary to choose organic fertilizer that has been formally treated and has no pollution to avoid harm to the environment and crops. Finally, the application of organic fertilizer also needs to be combined with the specific soil and crop conditions, and a reasonable fertilization plan should be formulated.
To sum up, organic agriculture, green agriculture and some specific crops are the main areas where organic fertilizers are applied. Through the application of organic fertilizer, soil structure can be improved, soil fertility can be improved, the growth and development of crops can be promoted, and the ecological environment and human health can also be protected. Of course, there are also some issues that need to be paid attention to in the process of applying organic fertilizer to ensure its effectiveness and safety.
