Cow manure contains many undigested plant residues and is rich in minerals. This is dung material, which is very suitable for the preparation of organic fertilizers. Many manufacturers of organic fertilizers choose cow manure for the production of organic fertilizers. The first step in the manufacture of organic fertilizers is their composting and fermentation.
So how to transform cow manure into organic fertilizer by means of fermentation of composting?
First add to fresh cow pile to straw, rice bran and other auxiliary materials, which make up 10-15% of the total number of enzyme cow manure. Play the role of humidity regulation, ventilation and ratio of carbon and nitrogen. The humidity of the cow manure is maintained at the level of 60%, and the ratio of carbon-Azot is within the limits 30-40.
Add 0,04% The leaven (First mix the leaven with a 10-fold amount of bran, and then add it to the cow manure and mix well). After mixing, place it in a fermenter groove. Red width 2 m, Lower width 3 m, height 1,2 m. The length depends on the length of the fermentation tank of the groove. Place it well and seal it, To seal. Then cover it polyethylene fabric and waterproof fabric, Fermentation time will be about 15-40 days.
Turn over in noon every 10 days in winter and spring, and in the summer and autumn to turn every 5 days. The fermentation temperature of the material is controlled in the range of 55-70 ° C, And the fevering temperature can be measured and controlled by Thermometer with a digital display of a rod type. Usually fermentation can be completed, Turning a bunch of about three times.
How to adjust the humidity of the compost heap?
Under normal conditions, moisture content in the litter of livestock and poultry, such as fermented cow manure, should be controlled at the level of 40–65%.
How to determine, whether the humidity of the cow manure is located in this range? You can hold a handful of cow manure in your hand and see watermarks between your fingers, Not dripping. As soon as you let him go, He will run away, Having hit the ground. Arming will be slower, if there are fewer water, And the breathability will be worse, If there is more water. Therefore, you need to control the moisture content. If the humidity is too high, You can add straw, sawdust, The remains of the mushrooms, Powder of dry earth and t. e in., To reduce moisture content.
What modern equipment and equipment can you use for composting?
If you need to process a large amount of cow manure, They can help you Pinaton composter And Wheel composter. Both are high -quality equipment, suitable for turning large volumes. If you have a relatively small processing volume, then we recommend that you choose Caterpillar composters And Self -propelled composters.
Certainly, If you feel, that your cow manure should not be invested in equipment for its processing, You can also compost it yourself.
