The subject of the invention is the substrate for soilless cultivation of plants, which is completely organic, made from natural and environmentally-friendly materials, using brown coal, as well as fully biodegradable and rich in nutrients throughout the period of plant growth, providing stable conditions for air and water, high hydrophility of the substrate, thermal buffer-ability, as well as good transformation of water and gas, and at the same time characterized by a durable and homogenous structure, which is slowly biodegradable, being packed in the form of rectangular bales stretched over with the foil sleeve.According to the invention, the substrate is natural brown coal fragmented into single fractions of particles with the diameter from 1.0 to 20 mm and/or into the earth fraction, wherein the proportions of air and water of this substrate are controlled by the selection of graining and/or adding the earth fraction.
