FIELD: agriculture, more particularly manufacture of substrates for hotbeds. SUBSTANCE: addition of 10% additive of 0.5-3 mm finely dispersive fraction of zeolite to compost made of wood bark improves aeration, water retention capacity and optimizes conditions for mineral nutrition of plant. Wide range of ash elements improves nutrient value of the substrate. In addition, unlike well known substrates, the claimed substrate is free from seeds of weeds, has prolonged service life due to constituents or said substrates: 100 parts of composed bark and 10 parts of zeolite. EFFECT: improved properties of the substrate. |
