In recent years, the European countries recycle only 5−7% of bio-waste. One activity of the biological waste disposal is granulation. The production of fertilizer from animal manure with supplement represents an important area of environmentally friendly bio-fertilizer production. This paper presents an investigation of estimation manure compost physical-mechanical properties for reuse of organic waste − cattle and cow manure, sugar production waste − molasses through new technology pellets production and of granulated fertilizer impact on soil. The experimental manure samples produced by industrial methods and samples produced in the laboratory from the time period of 2014 to 2017 were investigated. The following physical – mechanical characteristics were estimated: biometric indicators (dimensions, mass), volume and density of raw material and pellets, material and pellet’s humidity and pellets strength. Experiments results have shown that the difference in limit strength between experimental and industrial organic compost pellets was about 5%. Experiments of fertilizers on the impact on soil shown that the amount of nutrients added to the soil depends on the rate of the granulated compost fertilizer. As the norm increases, organic carbon, humus, mobile phosphorus and potassium increase in soil. Increases in soil fertility, improved agrochemical properties, soil organic matter accumulation and humus increase. Granulated compost fertilizers have no effect on soil acidity. The presented results could be helpful to the development of the fertilizing process by the granulated compost fertilizer for improvement of soil quality in small farms.

研究颗粒肥料堆肥的物理机械特性和对土壤的影响

近年来，欧洲国家仅回收了 5-7% 的生物垃圾。生物废物处理的一项活动是造粒。以动物粪便为原料生产肥料是环保生物肥料生产的一个重要领域。本文通过新技术颗粒生产和颗粒肥料对土壤的影响，对有机废物 - 牛粪、制糖废物 - 糖蜜的再利用进行了评估粪便堆肥物理机械特性的研究。对2014-2017年工业方法生产的实验粪便样品和实验室生产的样品进行了调查。估计了以下物理-机械特性：生物识别指标（尺寸、质量）、原料和球团的体积和密度，材料和球团的湿度和球团强度。实验结果表明，实验和工业有机堆肥颗粒的极限强度差异约为5%。肥料对土壤影响的实验表明，添加到土壤中的养分量取决于颗粒化堆肥的比例。随着标准的增加，土壤中的有机碳、腐殖质、移动磷和钾增加。增加土壤肥力，改善农业化学性质，土壤有机质积累和腐殖质增加。颗粒状堆肥对土壤酸度没有影响。所呈现的结果可能有助于开发粒状堆肥施肥工艺，以改善小型农场的土壤质量。材料和颗粒的湿度和颗粒强度。实验结果表明，实验和工业有机堆肥颗粒的极限强度差异约为5%。肥料对土壤影响的实验表明，添加到土壤中的养分量取决于颗粒化堆肥的比例。随着标准的增加，土壤中的有机碳、腐殖质、移动磷和钾增加。增加土壤肥力，改善农业化学性质，土壤有机质积累和腐殖质增加。颗粒状堆肥对土壤酸度没有影响。所呈现的结果可能有助于开发粒状堆肥施肥工艺，以改善小型农场的土壤质量。材料和颗粒的湿度和颗粒强度。实验结果表明，实验和工业有机堆肥颗粒的极限强度差异约为5%。肥料对土壤影响的实验表明，添加到土壤中的养分量取决于颗粒化堆肥的比例。随着标准的增加，土壤中的有机碳、腐殖质、移动磷和钾增加。增加土壤肥力，改善农业化学性质，土壤有机质积累和腐殖质增加。颗粒状堆肥对土壤酸度没有影响。所呈现的结果可能有助于开发粒状堆肥施肥工艺，以改善小型农场的土壤质量。实验结果表明，实验有机堆肥颗粒与工业有机堆肥颗粒的极限强度差异约为5%。肥料对土壤影响的实验表明，添加到土壤中的养分量取决于颗粒化堆肥的比例。随着标准的增加，土壤中的有机碳、腐殖质、移动磷和钾增加。增加土壤肥力，改善农业化学性质，土壤有机质积累和腐殖质增加。颗粒状堆肥对土壤酸度没有影响。所呈现的结果可能有助于开发粒状堆肥施肥工艺，以改善小型农场的土壤质量。实验结果表明，实验有机堆肥颗粒与工业有机堆肥颗粒的极限强度差异约为5%。肥料对土壤影响的实验表明，添加到土壤中的养分量取决于颗粒化堆肥的比例。随着标准的增加，土壤中的有机碳、腐殖质、移动磷和钾增加。增加土壤肥力，改善农业化学性质，土壤有机质积累和腐殖质增加。颗粒状堆肥对土壤酸度没有影响。所呈现的结果可能有助于开发粒状堆肥施肥工艺，以改善小型农场的土壤质量。
