METHOD FOR DEVELOPING AND INCREASING, RESP. THE FERTILITY OF SOIL

The present invention relates to a process for developing and increasing resp. the fertility of soil, which comprises, if necessary, purifying the natural water and/or permeating and ground water polluted by a known method, i.e. feeding water into area where aquatic plants are growing and water can be used for irrigation, inoculating soil algae having convenient productivity on the field to treated with algae and helping the algae to propagate in order to complete formation and increasing of soil humus, before, during or after treating field with algae, increasing selectively the amount of humus in the irrigating water and ensuring plant nutrient existing and supplying to the irrigating water, preferably in the form of a continuous organic synthesis.
