Fermenting sawdust bark chips into good fertilizer

Fermentation of Sawdust Bark Sawdust into Good Fertilizer Some parts of our country are sparsely populated. The land is covered by forests and green areas. In addition to the production and living of forest resources in these places, there is a large amount of surpluses and waste, such as branches, sawdust, sawdust, and the like. If these wastes are not dealt with in time, they will be piled up in large quantities. This will not only occupy land and pollution, but also waste organic resources. Fertilizer starters can quickly turn them into good fertilizers, which can then be sold in simple packages. The economic benefits are doubled, and it is definitely a good way to get rich!

How do you do it? The main components of sawdust bark are mainly cellulose and lignin. Fermentation auxiliaries can be added according to one-thousandth of the fresh weight of the material or one-thousandth of dry weight when processing. (Please note that other similar products generally To be added at a dosage of three-thousandths to five-thousandths, the amount and cost of the additive should be increased by several times.) The chicken manure can be added to the material at a rate of about 10% to adjust the ratio of carbon to nitrogen (C/N). Instead, the replacement ratio is: 1 kg urea replaces 100 kg of chicken manure), and the appropriate proportion of carbon and nitrogen is 30:1 and the moisture content is 60-70%. Sawdust bark during the processing of organic material fermentation aids, due to the growth and reproduction of cellulose decomposing bacteria in the later period, the material quickly warms up, the maximum temperature can be raised to about 75 °C, about 65 °C should be overturned, generally about 10 days material color change Dark black or dark brown, basically charred, the material is lightly pulled by hand, broken, aromatic or pure mud smell, the end of the fermentation. It's that simple.
