Solid peroxy compounds have been increasingly applied for the removal of organic pollution from contaminated groundwater and soil due to their ability to release oxygen and hydrogen peroxide. The influence of two solid peroxy compounds (sodium percarbonate, 2NaCO·3HO and calcium peroxide, CaO) with poultry manure (PM) added to contaminated soil on the growth of the tested plants ( and ) and the quality of soil water leachates was investigated. A series of experiments involving the addition of CaO and 2NaCO·3HO at the dose of 0.075 g/g PM improved the growth of tested plants. The conducted study indicated that the use of peroxy compounds not only removed pathogens from livestock waste, but also improved the quality of plant growth. The calculated factors for the growth of roots (GFR) and growth of shoots (GFS) in soils treated with a mixture of peroxy compounds and PM were higher than in soils treated only with PM. The physicochemical analysis of soil water leachates indicated that solid peroxy compounds may be a promising alternative compared to the currently used hygienizing agent such as calcium hydroxide (Ca(OH)). Solid peroxy compounds increased the bioavailability of components necessary for proper seed germination and plant growth (N, P, K, Ca, Mg and S). In most of the studied cases, the obtained plant shoot and root growth rates were higher for soil mixtures containing organic waste deactivated by biocidal compounds, compared to soils that contained only poultry manure.
由于固体过氧化物能够释放氧气和过氧化氢，它们已越来越多地应用于去除受污染地下水和土壤中的有机污染物。研究了两种固体过氧化物（过碳酸钠，2NaCO₃·3H₂O和过氧化钙，CaO₂）与添加到家禽粪便（PM）中的受污染土壤对受试植物（和）生长以及土壤渗滤液质量的影响。一系列涉及以0.075 g/g PM的剂量添加CaO₂和2NaCO₃·3H₂O的实验改善了受试植物的生长。进行的研究表明，使用过氧化物不仅可以去除牲畜粪便中的病原体，还可以提高植物生长质量。用过氧化物和PM混合物处理的土壤中根系生长（GFR）和地上部生长（GFS）的计算因子高于仅用PM处理的土壤。土壤渗滤液的物理化学分析表明，与目前使用的卫生剂如氢氧化钙（Ca(OH)₂）相比，固体过氧化物可能是一种有前景的替代品。固体过氧化物提高了种子正常萌发和植物生长所需成分（N、P、K、Ca、Mg和S）的生物有效性。在大多数研究案例中，与仅含有家禽粪便的土壤相比，含有经杀菌化合物灭活的有机废物的土壤混合物所获得的植物地上部和根系生长速率更高。
