By green-house trials optimal dosages were determined, as 1000 to 3000 l/ha (1500 l/ha, 25%) for Bituplant 22, 100 kg/ha for Sarea Soil Stabilizer and 75 l/ha for Sarea Evaporation Inhibitor. Spraying became much easier and better efficiency was reached, if the products were combined in a tank mixture.

By the use of soil stabilizers not only wind erosion was prevented, but also soil puddling and soil crusting, which meant better penetration of water into the soil. In phytotron trials evaporation was reduced up to 60% by Bituplant 22, and more than 50% by Sarea Evaporation Inhibitor. Product finding has become easier, and specific field trials will be made possible by tests in the green-house and in the phytotron.
