Not all summer residents consider sawdust to be a good fertilizer, and there are good reasons for this.
However, even this material can be turned into plant food.
Nitrogen absorbers
The soil loses more from fresh sawdust than it gains. This is all due to soil bacteria that process wood and actively absorb nitrogen from fertile soil. In addition, fresh sawdust contains substances harmful to plants, such as resins.
Some summer residents pile the material in a heap and hope that it will rot, decompose and become an excellent fertilizer. But this will take many years. A large pile of sawdust will not get wet to the very bottom during rain. Over time, a crust will form and most of the material will end up in a kind of "preservation".
How to make fertilizer
Sawdust is converted into fertilizer in the following way:
1. Spread out a film onto which the wood material is poured in layers. Each of them is watered with a urea solution (170-200 g per 10 l of water).
2. Cover the sawdust with film and turn it over with a shovel every 12-14 days.
3. After about 2 months the material will turn black and become an excellent organic fertilizer that will not cause nitrogen deficiency.
There is an express option for feeding. Wood shavings are sprinkled with any nitrogen fertilizer (20 g per 1 kg) and dug into the soil directly on the beds.
