Can sawdust be used as fertilizer?
Eucalyptus sawdust can be used as organic fertilizer.

Eucalyptus sawdust does not belong to coniferous tree species, and wood does not contain antibacterial substances. Therefore, eucalyptus sawdust, like sawdust of other broad-leaved trees, is easy to ferment and decompose. After decomposition, it can provide nutrients to crops slowly and continuously, and can be used as organic fertilizer to improve soil.

Stacking method:

Because there are relatively few nitrogen-containing substances in sawdust, it is suggested to supplement appropriate amount of nitrogen fertilizer during fermentation, or pile it up with human and animal feces for fermentation at the same time. This kind of fermentation belongs to aerobic fermentation, so it is recommended to turn over the pile once or twice during the composting process. Turning the parts around the periphery into the inside at one time can speed up the fermentation and make all fertilizers ferment thoroughly.
