Promising methods for managing poultry manure (PM) include converting poultry manure through pyrolysis to biochar, which can be used for soil applications. The overall goal of this study was to determine the effects of poultry manure-derived biochar and compost on the soil and growth of cherry tomatoes. The biochar obtained at 475 °C was characterized by a relatively high organic matter content of 39.47% and nitrogen content of 3.73%, while it had the lowest C/N ratio of 8.18. According to the recommendations of the EBC, the biochar obtained at 475 °C demonstrated the most beneficial effects in terms of fertilizing potential. The composting of poultry manure with the straw was successful, and the limit of 60 °C was exceeded, which allowed for the hygienization of the compost. The produced compost and biochar are sanitary safe and do not exceed the limits of heavy metal content. The lowest plant biomass was obtained from growing medium A with 3.6 g wet weight (0.24 g dry weight). The measurements of the height of cherry tomatoes showed that growing media D, E, and F allowed the plants to obtain from 602 to 654 mm in height.
处理家禽粪便（PM）的有前景的方法包括通过热解将家禽粪便转化为生物炭，生物炭可用于土壤改良。本研究的总体目标是确定家禽粪便衍生的生物炭和堆肥对樱桃番茄土壤和生长的影响。在475℃下获得的生物炭的特征是有机质含量相对较高，为39.47%，氮含量为3.73%，而其碳氮比最低，为8.18。根据欧洲生物炭证书（EBC）的建议，在475℃下获得的生物炭在施肥潜力方面表现出最有益的效果。家禽粪便与秸秆的堆肥很成功，超过了60℃的限制，这使得堆肥得以卫生化处理。所生产的堆肥和生物炭在卫生方面是安全的，且重金属含量不超标。从生长介质A中获得的植物生物量最低，湿重为3.6克（干重为0.24克）。樱桃番茄高度的测量结果表明，生长介质D、E和F使植株高度达到602至654毫米。
