Product Description
Organic material composting agents were mainly promoted for the rapid composting of crop residues such as rice, corn and wheat straw.
Benefit
Based on feedback from users of organic material composting agents, the product mainly generates the following benefits. Organic material composting agents not only effectively utilize agricultural waste and make a significant contribution to improving soil organic matter but also have remarkable effects in solving soil-borne diseases, overcoming crop rotation diseases, loosening soil, improving fertilizer utilization rates, and improving the quality of agricultural products, with an average increase in yield of more than 5-10%. The use of organic material composting agents can effectively save production costs, increase crop yields, reduce environmental pollution, not only bringing income and cost savings to farmers but also being an ideal organic fertilizer for green organic agriculture, fully meeting the needs of national modern agricultural development, and having significant strategic significance for promoting sustainable agricultural development, with very significant social and ecological benefits.
In summary, through the development, utilization, and market promotion of organic material composting agents, the company has brought practical benefits to farmers, achieving significant economic, social, and environmental benefits.

Usage
1. Pre-treatment of Straw
Shred the straw with a shredder or cut it with a hay cutter to a length of about 5 cm. Soak the straw for one day or thoroughly wet it to a moisture content of 55%-65%. The straw should be damp enough to drip water when squeezed (adjust flexibly according to the water retention capacity of the straw).
2. Adjustment of Carbon-Nitrogen Ratio of Materials
Add 0.2%-0.5% urea (calculated based on the weight of the straw, the amount of urea added varies according to the type of straw) during soaking or watering. The main purpose of adding urea is to regulate the carbon-nitrogen ratio of the material, which should be controlled between 25:1 and 30:1.
3. Use of Composting Agent
Method 1: Use 4-8 kg of organic material composting agent per 1000 kg of straw. First, mix the composting agent with cornmeal at a ratio of 1:3 (cornmeal serves as a nutrient for activating the bacteria). Then, apply 8-12 kg of the mixture per 1000 kg of straw in layers, and after spreading, spray with water to moisten.
Method 2: Use 4-8 kg of organic material composting agent per 1000 kg of straw. First, prepare a culture medium for the composting agent to shorten the fermentation lag phase and reduce the fermentation cycle. The culture medium formula is: 2 kg potatoes (peeled and chopped), 18 kg water, boil over medium heat for 15-20 minutes, filter the liquid, add 200 g brown sugar (or glucose), and let it cool for later use. When stacking the straw, spread a layer of bacterial powder every 20-40 cm, and then evenly spray the cooled liquid culture medium onto the bacterial layer.
4. Stacking of Straw
Stack in rows 2-3 meters wide and 1.0-1.5 meters high, leaving appropriate air holes at the bottom. Spread the bacterial agent every 20-40 cm during stacking, and lightly compact with a shovel. After stacking, evenly cover the straw pile with 3-5 cm of field soil, spray the soil to moisten it thoroughly, and then cover with a layer of straw mats to prevent water evaporation and nutrient loss. If in a low-temperature season or in areas with high water evaporation, cover with plastic film.
5. Fermentation Process Control
(1) Temperature Control: The environmental temperature should be above 10°C, especially during the initial fermentation period, as low temperatures can affect the growth and reproduction of microorganisms. From the beginning of composting, measure the internal temperature of the pile daily. If the internal temperature exceeds 65°C, pay attention to supply water and aeration to control the temperature, and turn the pile in real-time if the temperature continues to rise.
(2) Moisture Control: Moisture is always a key factor in fermentation. Due to the long fermentation period and water loss during the process, it is necessary to timely and appropriately supply water when the soil and materials become dry in the middle and early stages to prevent a decrease in water activity that affects the fermentation rate.
(3) Fermentation Cycle: The fermentation cycle is generally 15-30 days in summer and autumn, and 20-45 days in spring and winter. Different types of straw and fermentation process controls may result in varying fermentation cycles.
6. Determination of Fermentation End Point
After fermentation, when the temperature of the material pile shows a significant and continuous decrease and no longer rises, the material has undergone significant humification, is easily crumbled by hand, changes color from yellow to brownish-yellow or black, and has a slight ammonia smell.
