ABSTRACT:
A method is described to utilize used open-cast lignite mines by installing greenhouses with technological products attaining water economy of 7-8 times, unlimited nutritional capacity by enclosing pesticides and nutrients in a system of resins so as to release elements gradually, and with addition of calcium carbonate so as to limit the creation of sulfuric acid by the action of ground bacteria without pollution of the soil. This limits the need to move the greenhouses, and constitutes an original solution of agricultural utilization of these otherwise toxic and infertile soils.
