Living organisms maintain water in soil so that they have enough for themselves – and thus keep it for us as well.
60 % of human body is made up of water, which we have to refill from water sources. 90 % of available water is kept in soil in the form of soil moisture, with only a small portion flowing into wells and watercourses. A single-digit rate of decrease of humidity therefore results in a dramatic decline in water levels in watercourses and wells. In order to maintain sufficient water resources for our children, we have to make efforts to keep water in soil.
We are capable of producing structures which can be inserted into soil and whereby we are able to improve water retention. This process, however, has proved extremely time- and energy-consuming, expensive and difficult to implement. At the same time, the very same job is being done efficiently by billions of small animals and microorganisms which work hard to create capillary humus structures which retain moisture. These organisms, which we summarily call soil life or edaphon, secure sufficient water for themselves but also for plants and springs. They need only one thing from us – not to kill them and force them out of soil.
Once retained in soil by microorganisms, water evaporates, which in turn cools the surface. Such ingenious land- and air-conditioning with giant output efficiently attenuates the greenhouse effect, equilibrates temperatures and mitigates violent climatic events including windstorms and rainstorm flooding.
