In agricultural production, organic fertilizer is the "treasure" that nourishes soil and fertile land, providing comprehensive nutrition for crops such as vegetables and grains, making the soil more fertile and crops stronger. However, traditional organic fertilizer fermentation often faces three major challenges: a long fermentation cycle, ranging from several months to six months; Stinky odor and environmental pollution; Incomplete fermentation can easily lead to root and seedling burning, causing diseases and pests, which has deterred many farmers. In fact, mastering scientific methods can make organic fertilizer ferment quickly and effectively.

Efficient fermentation has "tricks", and solid and liquid methods are suitable for different needs. Solid organic fertilizer fermentation can collect animal feces, straw, leaves and other raw materials, adjust the moisture content to 50% (grab them into a ball without dripping water), mix 1000 kilograms of raw materials with 1 kilogram of fermentation agent (such as EM bacteria, organic fertilizer fermentation agent), stack them, and cover them with plastic cloth. When the temperature reaches 50 ℃ on the third day, flip the pile and repeat 2-3 times until the material has no odor and white mycelium is formed. The high temperature can also kill bacteria and insect eggs. Liquid water-soluble fertilizer can be soaked in soybean cake, rice washing water, etc. with 5 times the amount of water, added with 0.1% -0.2% bacterial agent, covered with a film for half a month, and mixed with 5-10 times the amount of water before application or spraying, which is convenient and efficient.

There are also "customized solutions" for different scenarios: dry manure fermentation can build a pile 1-1.5 meters high, with breathable holes covered with a film, and flipped 3-4 times; Liquid manure should be fermented in a 40-50 centimeter deep fermentation tank, covered with film for warming, and regularly stirred; Large scale production can be achieved through high-temperature fermentation equipment, which can mature within 8 hours, or by creating a closed environment with compost film, shortening the cycle and promoting environmental protection. Nowadays, the "company+farmer" dual pool alternating fermentation model has solved the problem of pig farm manure treatment and achieved low-cost conversion of manure into fertilizer.

With the increasing awareness of environmental protection and the promotion of green agriculture, the organic fertilizer industry is entering a golden period. The global market continues to grow, with increased support from Chinese policies and continuous breakthroughs in technological innovation - biotechnology enhances fertilizer activity, and intelligent manufacturing improves production efficiency. Choosing scientific fermentation methods can not only turn waste into treasure and reduce pollution, but also provide high-quality fertilizers for agriculture and promote sustainable development. In the future, organic fertilizers will become the "main force" of agricultural production, injecting strong impetus into ensuring food security and ecological protection.
