Wood chips can be buried in the form of pruning scraps or woodchips to significantly increase the content of stable carbon in the ground thanks to the high lignin content. If used on a massive basis, without further action, it can cause the temporary loss of fertility due to alteration of the carbon/nitrogen ratio in the soil. On the other hand, the soil will obtain numerous benefits of both a chemical and physical nature over time. Basically, this practice improves the water retention ability of the soil, creating excellent porosity. It helps combat erosion by improving the structure of the soil. In specific cases, the woodchips can be used as a natural mulch, drastically reducing water evaporation from the ground. However, cuttings buried in the vineyard may result in diseases being carried so it may be useful to put them into round bales and produce biochar to apply once again to the terrain. The technique has been extensively revalued in recent years.
