Growing of grass, radish, onion and marigolds in vermicompost made from pig manure and wheat straw

Podzolic soils belong to a low fertile soils. To obtain a crop it is necessary to add fertilizers. It was suggested to use vermicompost as fertilzer. Vermicompost is a natural fertilizer that is beneficial against chemical fertilizers. To confirm positive effect of biohumus different plants were grown. Grass and radishes were grown in forms, and radishes, onion and marigolds were grown in outdoor experimental plot. It was grown plants in poor podzolic soil with added vermicompost. Grass had a higher growth in medium with 4% vermicompost. The best foliage length of radish was for sample with 4% vermicompost added. Radish root crop diameter was 2.5 times more than control when growing in forms. In experimental plot radishes were grown with 43.5% increasing in weight and 17.7% increasing in diameter. Incorporation of vermicompost in amounts of 5 kg/m² and 7 kg/m² led to increasing the weight and diameter of onions. The length of onion leaves was slightly larger than control. Marigolds grown in vermicompost medium had the most powerful sprouts and greatest length. Marigolds stem diameter, flower diameter, and quantity of inflorescences were also higher than control. Obtained data indicates the success of using vermicompost for podzolic soils enrichment and plants growing.
