Abstract: To cultivate ground or waste deposits, particulate foamed urea resin in moistened with water and the moistened particles are then fed into more water, to produce a mixture of 0.5 to 5 parts by volume of water to 1 of the urea.resin. The mixture is then deposited with plant seeds or cuttings, as in DT 1279998. A cylindrical mixer with axial stirrers and an inlet with spray nozzles is provided for the mixing process.
