Microbial fertiliser has significant benefits for agricultural production and plant growth. Treating manure with microbial fermenters not only accelerates the decomposition of the fertiliser, but also destroys the insect eggs, grass seeds and harmful germs it contains, preventing the occurrence of pests and diseases. Rich in nutrients and superior in soil improvement, fermented fertilisers play an important role especially in modern green agricultural production. In this paper we will discuss the multiple benefits of fermented manures and demonstrate their contribution to plant health, crop quality and environmental protection.
1.Microbial fertilisers can provide consistent and stable nutrients
Microbial fertilisers contain a wide range of nutrients needed by plants, including basic nutrients such as carbon, nitrogen, phosphorus and potassium, as well as a variety of trace elements. These elements are broken down into forms that can be directly absorbed by plants during the fermentation process, providing a stable and continuous supply of nutrients to plants. Compared to chemical fertilisers, microbial fertilisers release nutrients more slowly and persistently, and can maintain their effectiveness over time to meet the long-term growth needs of plants. In addition, the sugars and organic matter in microbial fertilisers release a lot of energy during the decomposition process, which promotes the reproduction of microorganisms in the soil and further improves soil quality.
2.Microbial fertilisers can improve soil structure
Microbial fertiliser plays an important role in improving soil structure. The application of fermented farmyard manure increases the organic colloids in the soil, which promotes the agglomeration of soil particles and the formation of a stable granular structure. This structure greatly improves the water and fertiliser retention and permeability of the soil, providing a more suitable growing environment for plant roots. Especially those with a fine texture, easy to agglomerate the soil, microbial fertiliser can be significantly improved after application, increasing soil aeration and water infiltration capacity, to avoid the phenomenon of soil agglomerates lead to poor development of the plant root system.
3.Microbial fertiliser can enhance the plant's ability to resist diseases and pests.
Microbial fertiliser can effectively kill pathogenic bacteria, weed seeds and pest eggs during high-temperature fermentation. Generally speaking, the fermentation temperature of farmyard manure can reach 60-70 degrees Celsius for 6-7 days, and then after appropriate turning to maintain the same temperature inside and outside, this high temperature can completely eliminate the spreading factors of pests and diseases, thus greatly reducing the incidence of crop pests and diseases. At the same time, microbial fertiliser can also improve plant disease resistance, enhance drought resistance and promote healthy plant growth.
4.Microbial fertiliser can promote soil enzyme activity
Chicken, cow, sheep, pig and other animal manures contain a variety of active enzymes that are further released during the microbial fermentation process, increasing enzyme activity in the soil. Soil enzymes play a key role in improving the absorption, buffering and stress resistance of the soil. The humic substance in microbial fertiliser is a polymeric substance with high cation exchange capacity, which can effectively adsorb heavy metal ions and reduce the toxicity of heavy metals to crops. This is particularly important for the production of pollution-free green food, and also provides strong support for sustainable agricultural development.
5.Microbial fertiliser can avoid seedling burning
Unfermented manure such as chicken, cow, sheep, pig, horse and other manure, especially fresh animal manure, if applied directly to the soil, will ferment at high temperatures in the soil, resulting in plant seedlings being burnt by excessive temperatures. This is because, in the natural environment, unfermented manure continues to decompose, releasing heat and harmful intermediates that can easily damage plants if they come into direct contact with the seedlings. The micro-organisms in compost are converted into harmless substances after fermentation and no longer pose a threat to the plants, greatly reducing the risk of seedling burns.
6.Microbial fertiliser is good for the environment
Microbial fertilisers not only benefit plant growth, but also play an important role in environmental protection. Organic waste that is not composted by microbes, such as animal manure, often emits unpleasant odours and can easily pollute groundwater and surrounding water bodies when it rains. Microbial fertilisers do not have this problem. The special aroma produced during fermentation is not only harmless, but also improves soil fertility. In addition, microbial fertiliser can effectively reduce nitrate accumulation in the soil and increase vitamin C levels in crops, which can further improve crop quality.
7. Microbial fertiliser is beneficial to improve crop yield and quality
During the composting process of microbial fertiliser, complex macromolecular organic matter such as fibre, starch and protein are broken down into small molecule sugars and amino acids, which has a significant effect on promoting plant growth. Humic acid-like substances can effectively chelate phosphorus, potassium and other elements in the soil, acting as a slow-release fertiliser. This slow-release effect ensures that crops continue to receive nutrients throughout the growing season, effectively increasing crop yields. In addition, fermented fertilisers can also improve the disease resistance and tolerance of crops through the beneficial microflora they contain, further enhancing the quality of agricultural products.
8. Microbial fertilizers contribute to reducing the cost of fertilizer use
Microbial fertilizers significantly increase fertilizer use because the nutrients in compost microbes are more readily absorbed by plants than when applied directly to unfermented organic matter. Through the decomposition of compost microbes, the nitrogen in microbial fertilisers is converted into a plant-available form, reducing fertiliser wastage. This not only improves fertiliser efficiency, but also reduces the cost of fertiliser use in agricultural production, in line with the concept of sustainable development of modern agriculture.
In conclusion, microbial fertiliser has many benefits for plants. It can not only provide rich and continuous nutrition and improve soil structure, but also improve the disease resistance and environmental adaptability of crops. Through scientific and reasonable compost microbes fermentation treatment, farmyard manure has become an indispensable green fertiliser for modern agriculture, which not only helps to improve the yield and quality of agricultural products, but also provides a strong support for environmental protection and the development of ecological agriculture.
