CATDOLL : CATDOLL: How much is left after drying one ton of wet cow dung? (How many cubic meters is one ton of cow dung)

1. How much will remain after drying one ton of wet cow dung?

One ton of wet cow dung can separate 0.4 of dry cow dung.

Every 3 to 4 cubic meters of wet cow dung can be converted into 1 ton of dry cow dung.

Then, on average, each cubic meter of wet cow dung can be converted into 500 to 667 kilograms of dry cow dung, and a 1-ton dryer can dry cow dung equivalent to 2.5 tons of wet cow dung; that is, one ton. After wet cow dung is fermented, about 3,500 kilograms of dry cow dung can be produced, which is about the weight, because the water content of cow dung is about 65%!

2. How much dry cow dung can be produced from one ton of fresh cow dung?

One ton of cow dung can produce 60-70 kilograms of earthworms.

Note that feeding must be scientifically proportioned.

Recipe Example:

① 50% cow dung, 50% pulp sludge;

② 100% cow dung or 100% mixture of all livestock dung;

③ 20% each of cow dung, pig dung, and chicken dung, and 40% of rice straw; (Note: Chicken dung needs to be used to raise maggots or left for more than 1 year before it can be used to raise earthworms, otherwise the earthworms will all escape or die.

Feed preparation:

Fermentation: Use straw or stalks to lay a 10-15 cm thick layer of dry material, then lay 4-6 cm of manure on the dry material and repeat 3-5 layers. Use a watering can to spray water on each layer until the water seeps out. If garbage is used, pile one layer of garbage and one layer of manure. The length and width are not limited, and it is covered with a film. In the season with high temperature, turn it over every 7 days. Generally, turning it over 3-5 times completes the fermentation of the feed.

After the feed is fermented, test the pH value. Earthworm feed generally requires an appropriate pH value of 6-7.5, but the pH value of many animal and plant wastes is often higher or lower than this value. When the pH exceeds 9, acetic acid, salt or citric acid can be used as a buffer;

3. How much cooked cow dung can be fermented from one ton of raw cow dung?

Answer: 0.3-0.5 tons of cooked cow dung.

Cow dung is a cold fertilizer because of its fine texture and slow decomposition. How much cooked cow dung can be produced from one ton of raw cow dung? One ton of raw cow dung generally contains 90% water. To make cooked cow dung, the raw cow dung must first be dehydrated to a certain extent. According to general data: one ton of raw cow dung can produce about 0.3-0.5 tons of cooked cow dung. The specific output depends on the actual ingredients and the water content of the cow dung.

4. How many pounds does one ton of cow dung weigh?

One ton of cow dung weighs about 760 kilograms.

The water content of wet cow dung is 80%. To produce organic fertilizer, other auxiliary materials need to be added. Therefore, the weight of 1 ton of wet cow dung produced through fermentation, water evaporation, crushing and mixing is about 760 kilograms.

If the cow dung is not treated, it will breed a large number of mosquitoes and flies, and also cause the spread of bacteria. Using cow dung to process and produce organic fertilizer is in line with the environmental protection concept of waste utilization. Cow dung is a cold fertilizer, which ferments and matures slowly, and takes longer than other hot raw materials to ferment.

5. How many tons of wet cow dung are needed to make one ton of dry cow dung?

One ton of fresh cow dung generally contains about 90% water. To make organic fertilizer, you must first remove the water to below 30%. In this way, one ton of organic fertilizer will only have about 0.3 tons. Therefore, one ton of dry cow dung requires about 3.3 tons of wet cow dung.

Cow dung contains 10%-20% crude protein, 1%-3% crude fat, 20%-30% nitrogen-free extract, and 15%-30% crude fiber, so it has high nutrients. Hebei Yuanhai Biological Research has found that dry cow dung can be fermented into a high-quality organic fertilizer product. It can loosen the soil, improve soil compaction, chelate trace elements in the soil, and improve soil fertility.

Using cow dung as raw material to produce organic fertilizer has low cost, relatively stable quality and great market potential. However, the traditional composting method not only has a slow fermentation speed, but also cannot make the cow dung fully decomposed. After being applied to farmland, "secondary fermentation" is prone to occur, causing root and seedling burns.

6. How many cubic meters is one ton of cow dung?

One ton of cow dung is equal to 2 cubic meters.

One cubic meter of cow dung weighs about 760 kilograms, and one cubic meter of water weighs 1,000 kilograms.

The density of feces is about 1.2X10^3kg/m^3

Look at the moisture content. Generally, if the moisture content is 50%, one ton is 2 cubic meters.

Dry cow dung contains 10% to 20% crude protein, 1% to 3% crude fat, 20% to 30% nitrogen-free extract, and 15% to 30% crude fiber, so it has high nutritional value.

7. How many cubic meters of dry cow dung is equal to one ton?

The dryness and wetness of cow dung are different, and its specific gravity is also different, so the volume of cow dung of the same weight is also different. Generally speaking, the volume of one ton of dry cow dung is about 2.5 cubic meters.

Cow dung generally has a relatively high water content and a high weight when it is fresh. After the cow dung is fermented and dried, the water in the cow dung will evaporate and the specific gravity of the cow dung will become smaller.

8. How much biogas can be produced from one ton of cow dung?

One kilogram of dry cow dung can produce 0.3 cubic meters of biogas. So, one ton is 300 cubic meters.

Dry cow dung contains 10-20% crude protein, 1-3% crude fat, 20-30% nitrogen-free extract, and 15-30% crude fiber. It has high nutrient content and can become a high-quality organic fertilizer product after fermentation. It can loosen the soil, improve soil compaction, chelate trace elements in the soil, and improve soil fertility.

Biogas is a gas produced by the decomposition and metabolism of organic matter such as straw, weeds, human and animal feces, garbage, sludge, industrial organic wastewater, etc. under anaerobic conditions by a small amount of anaerobic microorganisms.

9. How much organic matter does one ton of cow dung contain?

One ton of cow dung can produce about 0.3-0.5 tons of organic fertilizer, which is related to the production process. Generally speaking, the water content of one ton of fresh cow dung is about 90%. To make cow dung organic fertilizer, the fresh cow dung must be dehydrated to a certain extent.
