A restored soil food web has positive impact on yields, nature and climate.
It is possible to restore soil life with home-made compost or worm compost in which the important groups of organisms are present.
If you want to buy organism-rich compost and compost with all desirable organism groups is unavailable, it is probably best to combine fungal dominant compost and good worm compost to get a hold of as many organism groups as possible.
In all cases, it makes sense to look at both soil and compost with a microscope to check if organisms are present or not. 2 weeks after inoculating the soil, another check should be done, to see if the organisms are already present in the soil in the right proportions. In general, this process should be repeated several times until the situation in the soil stabilises.
