<p>An organic water retention mix for use on soil includes paper sludge, dry sawdust or wood shavings, and muds obtained from the sediments of the water recycling plants and optionally limestone. The combination is mixed until the particle diameter size is between about 0.2 cm and about 1.5 cm to create a product that retains several times its dry weight in water and maintains high levels of humidity for long periods of time, transferring it gradually to the soil and subterranean layers of the soil where it is applied, whether soil is used for farming, grazing or forest soils, parks or recreational areas.</p> |
