Influence of Compost from Post-Consumer Wood on Development, Nutrition State of Plants, Microbiological and Biochemical Parameters of Substrates in Zonal Pelargonium (Pelargonium zonale)

The purpose of this study was to assess the possibility using compost made from post-consumer wood in zonal pelargonium (Pelargonium zonale) cv. ‘Tex Mex’ cultivation. influence on plant’s development and nutritional state, as well microbiological enzymatic activity substrate examined. Two variants marked with following letters: OPA OPB were used. Both consisted waste (OP) (70% weight) mixed powdery processing MDF boards (6%), mature fiberboard (19%), high peat (4%), water a biological inoculum “Activit Las”. Thirty kilograms urea two portions per prism added variant while ammonium nitrate (1.5 kg prism), magnesium sulphate (0.4 potassium phosphate (0.8kg prism) calcium (0.9 variant. plants cultivated into pots 12 cm diameter capacity 659 dm3 substrates consisting addition at different volume ratios. It found that medium type had significant growth flowering pelargonium. used determinant for total counts activity. chemical composition significantly modified plants’ state terms macro- microelements. In summary, demonstrated good quality ornamental can be successfully grown containing 25% or 50% compost.
