What are the details of pig manure fermentation?

Pig manure is commonly used organic fertilizer raw materials, this is because the difficulty of collecting pig manure is relatively low, with the popularization of large-scale farming, many breeding plants have also become organic fertilizer plants, so how should pig manure be fermented? Today, Tongda Heavy Industry will tell you what details should be paid attention to when pig manure fermentation organic fertilizer.

1. Temperature. The proper starting temperature of fermentation should be 25℃ ~ 35℃. If fermenting in winter, it is recommended to do it indoors or in a greenhouse. If outside, try to cover with plastic film for fermentation.

2. Proportion. First, 200g-300g organic fertilizer starter and 20kg-30kg bran powder are thoroughly mixed.

3. Water. Add the above mixture to 1 ton of organic fertilizer and mix well again (can be divided into small piles to mix, then mix the small piles together). According to the mixing situation, add water or feed appropriately, so that the water content is controlled at 40%-45%. The standard is to grasp a handful with your hand and hold it tightly, so that the water does not seep out.

4. Material pile size. The fermentation raw materials are directly stacked on the ground, the fermentation pile can not be too small, the height of 1.5 meters to 2 meters, the width of 2 meters, the length of 2 to 4 meters above the pile fermentation effect is better. It can be covered with a plastic sheet, etc., without sealing, and fermented. The fermentation process should be timely stirred, and according to the temperature to add or reduce water, usually twice.

5. Color. When the material no longer heats up and is loose and dark brown, the fermentation is completed.

After the fermentation of pig manure with organic fertilizer starter, the fertilizer efficiency is better, the use is more safe and convenient, and the utilization rate of fertilizer can be improved. Organic fertilizer starter can not only ferment pig manure organic fertilizer, but also ferment chicken manure, sheep manure, cow manure and other livestock manure into organic fertilizer, and the fermentation method is basically the same.

Finally, we should remind everyone that no matter what material is used to ferment organic fertilizer, we must grasp the moisture content, otherwise it will fall short.
