The material used for composting may contain pathogenic or harmful microorganisms, therefore, it is important issue to eliminate harmful or pathogenic microorganisms during the composting process to be used in plant production. Three different mixtures were prepared at initial C/N ratio of 35.34, 40.10, and 47 fixing the apple scab infected leaves at 62% dry weight basis. Composting study was carried out using three identical cylindrical reactors made of two nested plastic containers with 65 L. Temperature, moisture, carbon/nitrogen ratio, organic matter EC, pH, and O₂/CO₂ concentrations were monitored during process. Apple scab disease incidence of apple leaves and the colony number during composting, compost microbial population, and germination index of compost mixtures were determined. Except for the temperature rise to 65 °C for a short time at 7 days of composting for Mix‑1, all temperature for three mixes stayed between 24 and 46 °C. Disease severity of apple scab obtained from the compost samples showed that colony of apple scab after 16 days of composting were not detected. Furthermore, the population of beneficial microorganisms such as bacteria, actinomycetes, and fungi was colonized in the finished compost mixes. Germination index at the finished compost were above 80% for Mix‑1, Mix‑2, and Mix-3 at 10⁻³ dilution rate. In conclusion, composts obtained from apple scab infected leaves with dairy manure can be used reliably in agricultural production.

用于堆肥的材料可能包含病原微生物或有害微生物，因此，重要的问题是在用于植物生产的堆肥过程中消除有害或病原微生物。制备了三种不同的混合物，其初始C / N比分别为35.34、40.10和47，以62％的干重固定了被苹果黑星病感染的叶子。使用三个相同的圆柱形反应器（由两个嵌套的65 L的塑料容器制成）进行堆肥研究。温度，湿度，碳/氮比，有机质EC，pH和O ₂ / CO ₂在过程中监测浓度。确定了苹果叶片上的苹果疮ab病发病率和堆肥过程中的菌落数，堆肥微生物种群以及堆肥混合物的发芽指数。对于Mix-1，除了在堆肥7天的短时间内温度升高到65°C以外，三种混合物的所有温度都保持在24到46°C之间。从堆肥样品中获得的苹果黑ab病的严重程度表明，堆肥16天后未发现苹果黑ab菌落。此外，有益的微生物如细菌，放线菌和真菌的种群被定植在最终的堆肥混合物中。对于Mix-1，Mix-2和Mix-3，最终堆肥的发芽指数在10 ^-3时高于80％稀释率。总之，从苹果黑星病感染的叶片上加奶牛粪便得到的堆肥可以可靠地用于农业生产。
