There are two opinions about sawdust: some gardeners believe that sawdust does a poor job on the plot, while others believe that sawdust is the remains of plants and is useful.

Oddly enough, both gardeners are right. And it all depends on how the sawdust will be used in the garden.

What is sawdust

A by-product of wood processing is cellulose, which can be used as mulch or bedding.

However, such material has low nutrient content and can take a long time to decompose, making it less effective as a fertilizer.

The danger of sawdust is that it can take nitrogen from the soil and the plants will starve.

How to improve the beneficial properties of sawdust

To turn sawdust into one of the best fertilizers, you can add certain additives to it.

For 10 kg of sawdust, which corresponds to 3 buckets of sawdust, you need to take 100 g of urea, 25 g of double superphosphate, moisten the mixture with water, and after 3-4 days the combustion process begins.

The sawdust begins to release heat and, accordingly, the cellulose breaks down into elements that are more accessible to plants.

How to turn sawdust into a complete fertilizer

After 2 weeks, during which time these sawdusts have burned out and the volume has settled, they need to be mixed with compost in a 1:1 ratio.

After mixing, you need to wait another 2 weeks, and then you will have an excellent fertilizer that is suitable for mulching and adding to the soil.

This natural fertilizer contains many nutrients: nitrogen, phosphorus, potassium and all microelements, it is useful and safe for plants.
