“…6 and 7). Previous studies reported that the amount of available oxygen increased with the increase in content of calcium peroxide (Baker and Hatton, 1987). In our study, a high concentration of calcium peroxide (C2 + H 2 O) was more effective than a low concentration (C1 + H 2 O), which veri ed these previous ndings.…”

Purpose Waterlogging stress has a negative influence on agricultural production, particularly for rapeseed yield in a rice-rape rotation field. Calcium peroxide reacts with water to release oxygen, which can serve as an excellent supply. Methods In this field experiment, the conventional rape (Brassica napus L.) variety fengyou958 (FY958) and the early maturing rape variety xiangyou420 (XY420) were used to evaluate the effects of calcium peroxide on waterlogging resistance in a rice-rape rotation field. Waterlogging was imposed from the seedling to flowering stages, and three concentrations of calcium peroxide (0, C1 for the 0.594 kg plot− 1 and C2 for the 0.864 kg plot− 1) were added as basal fertilizer. Results Waterlogging decreased the yield of XY420 and FY958 rapeseed by 74.8% and 87.4%, respectively, while the leaf SPAD values decreased significantly by 17.2% and 21.5%. Treatment with calcium peroxide resulted in an increase of 151%-293% in the yield of rapeseed compared with the waterlogged plants. Moreover, calcium peroxide alleviated the peroxidation of leaves and decreased the activities of catalase and superoxide dismutase by 14.2%-44.4% and 10.9%-19.5%. Compared with the waterlogged plants, the contents of abscisic acid and ethylene in the C2 leaves decreased by 37.3% and 33.4%, while the content of gibberellin increased significantly by 44.9%. The belowground parts of the plants were also significantly affected. The treatments with calcium peroxide reduced the activities of fermentation enzymes in the roots, which significantly reduced the accumulation of fermentation products by 25.0%-57.1% and 16.5%-29.4% for lactate and ethanol, respectively. This reduction was owing to the improved levels of oxygen in the root environment that were released by calcium peroxide. Conclusions The application of a suitable concentration of calcium peroxide enhanced the resistance of rapeseed to waterlogging stress, and this study provides a valid method to prevent damage from flooding in rice-rape rotation fields.

“…Most investigations showed that seeds pelleting with calcium peroxide (CaO 2 ) promoted germination of rice and improved the plant growth [ 65 , 66 , 67 ]. It has been reported that seed rice ( Oryza sativa L.) coating with CaO 2 resulted in better germination, higher yield of rice plants (85%) and reduced mean emergence time of dry direct seeded rice [ 68 ].…”

Over the past years, the treatment and use of livestock waste has posed a significant problem in environmental engineering. This paper outlines a new approach to application of calcium peroxide (CaO2) as a green oxidizer and microbiocidal agent in the treatment of poultry manure. It also presents the application of pretreated waste in improvement of degraded soils in industrial areas. The CCD (Central Composite Design) and RSM (Response Surface Methodology) were employed for optimizing the process parameters (CaO2 concentration 1.6–8.4 wt %, temperature 5.2–38.8 °C and contact time 7–209 h). The analysis of variance (ANOVA) was used to analyze the experimental results, which indicated good fit of the approximated to the experimental data (R2 = 0.8901, R2adj = 0.8168). The amendment of CaO2 in optimal conditions (8 wt % of CaO2, temperature 22 °C and contact time 108 h) caused a decrease in bacteria Escherichia coli (E. coli) in poultry manure from 8.7 log10 CFU/g to the acceptable level of 3 log10 CFU/g. The application of pretreated livestock waste on degraded soils and the studies on germination and growth of grass seed mixture (Lollum perenne—Naki, Lollum perenne—Grilla, Poa pratensis—Oxford, Festuca rubbra—Relevant, Festuca rubbra—Adio and Festuca trachypylla—Fornito) showed that a dose of 0.08 g of CaO2 per 1 gram of poultry manure induced higher yield of grass plants. The calculated indicators for growth of roots (GFR) and shoots (GFS) in soils treated with poultry manure were 10–20% lower compared to soils with amended CaO2. The evidence from this study suggests that CaO2 could be used as an environmentally friendly oxidizer and microbiocidal agent for livestock waste.

“…Some of the hydroxide formed may react with atmospheric carbon dioxide to form calcium carbonate. In soil, the decomposition of hydrogen peroxide to water and oxygen may be catalyzed by enzymes such as catalase or peroxidase or by free cations (Baker and Hatton 1987). The contents of soil enzymes vary depending on the soil pH, organic matter content, types of vegetation, plant roots microorganisms, etc.…”

“…It is generally recognized that calcium peroxide supplies oxygen around the seed (Ota 1982;Baker and Hatton 1987). However, the variations in oxygen production from calcium peroxide in relation to soils and their impact on the genotypes have not been thoroughly investigated.…”
