With the wood chips obtained from fresh twigs you can fertilize the soil, improve its structure and increase water retention. The water content of the chopped (fresh) twigs is in fact sufficient to ensure the right amount of water and nutrients for many crops.
In his book The garden without waterwhich I recommend you read, Jacky Dupety explains how you can grow salad, tomatoes, peas etc… using the wood chips of (fresh) twigs instead of water. Of course you have to use it well, but it is technically possible and not only in the garden.
Furthermore, the use of the wood chips from twigs it goes well with the concepts of organic cultivation, zero impact and zero kilometer because it allows you to replace the use of chemical fertilizers with self-produced substances on site.
Broadening the discussion, as the author of the book does, we can say that cultivating with wood chips from twigs we contribute to the good of the planet and society by saving water and indirectly also oil. Both things are true, but the interest in this technique is given above all by the 'domestic' advantages that are immediately visible.
Especially because today we produce wood chips from twigs it is easy and affordable for everyone, thanks to the shredders. In the previous article Shredder: an ally in the garden I talked about the advantages of these devices for those who own a piece of land and in a subsequent article I presented the Bosch electric shredder that I had the opportunity to use. We are talking about electric machines, therefore non-polluting and easy to manage, but no less powerful as they chipping branches up to 10 cm in diameter.
The wood chips from twigs it is a component of the natural fertilizer that everyone can self-produce at home and is also an excellent fertilizer. In fact, it contains a high percentage of dry matter which helps to make the vegetables or cereals in the field richer from a nutritional point of view and easier to store.
