摘要:A greenhouse pot study was conducted to evaluate the use of a slaughterhouse waste compost (SWC) as fertilizer for potted geranium plants. This SWC was mixed with agave bagasse compost (ABC) at rates of 0%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% and 100% by volume. The effects of the SWC on the germination and initial growth of Raphanus sativus were also examined. Samples of SWC and ABC were used to prepare 6 different mixtures: (1), 50% sand, 25% bark and 25% peat, (2), 50% sand and 50% peat, (3), 50% sand, 25% bark and 25% SWC, (4), 50% sand and 50% SWC (5), 50% sand, 25% bark and 25% ABC and (6), 50% sand and 50% ABC. Samples of these mixtures and SWC and ABC, were analyzed for bulk density, easily available water (EAW) and water buffering capacity (WBC). Potted geranium plants grew well in mixtures of SWC and ABC with no additional fertilization. High volumes of SWC (70 to 100%) had no adverse effect on root growth, on subsequent plant growth and development, or on the flowering process. SWC had no detrimental effect on Raphanus sativus seeds germination (p ≤ 0.05). Conditioning soils with SWC and ABC increased soil bulk density (p ≤ 0.05). Easily available water and water buffering capacity results suggest that SWC and ABC can substitute peat.
