There are many tools for organic compost machine
of materials. We are compost machine manufacturers. Our organic compost machines are complete in variety. As long as you provide the site, we can help you design your fermentation tank for free.
What are the methods for identifying organic fertilizers?
1. Plastic bag method (compost based on livestock and poultry)
The compost product mainly based on livestock and poultry is sealed in a plastic bag. If the plastic bag does not bulge, it can be concluded that the compost product is decomposed (the gas is produced by the unfermented fertilizer).
2, germination test method
5g of air-dried product was placed in a 200 ml beakers, soaked in 100 ml of warm water at 60 ° C for 3 hours, and then filtered. 10 ml of the juice was filtered out, poured into a pewter dish with two layers of filter paper, and 100 grains of cabbage were sorted. The seeds of radish, cucumber or tomato are subjected to a germination test. In addition, the control dish is distilled water, and the seed and germination test methods are the same as above. It is generally considered that the germination rate is more than 90% of the control area, indicating that the product has been fermented and qualified. This method is especially suitable for the identification of products containing lignocellulosic materials.
3, earthworm method
Prepare a few enamel, as well as cups and black cloth. Put the broken product in the cup, then put the cockroach into it, cover the cup with a black cloth. If you sneak into the inside of the product, it means that it is decomposed. If you climb on the pile, you will not sneak into the pile, indicating that the product is not fully cooked. There are phenol or ammonia residues.
The wastes suitable for this technology include:
(1) Feces, animal manure such as chicken manure, pig manure, cow dung, sheep dung, horse dung;
(2) Straw corn stalks, straw, wheat straw, bean straw and other crop straws;
(3) Crustacean husk, rice husk powder, peanut shell powder, peanut meal, gluten, bacillus, etc.;
(4) Dregs, distiller's grains, soy sauce, vinegar grains, furfural residue, xylose residue, enzyme residue, garlic residue, sugar residue, etc.;
(5) Cakes, bean cake, soybean meal, oil cake, rapeseed cake, etc.;
(6) Others Domestic sludge, sugar mill sludge, sugar sludge, bagasse, etc.
It is made into an organic fertilizer that meets the NY525-2002 (2012) standard by bio-fermentation.
