“…At the later stage of the experiment, with the participation of a large number of microbial agents in nitrification, the nitrogenous organic matter was used up and the irritating odor largely disappeared, and the pH slowly decreased and stabilized. This is consistent with the findings in the studies of Kim et al (2012) and Yamane (2016) . The use of pH indicators to track the environment within the pile during bovine manure fermentation can provide effective insight into the utilization of organic matter by microorganisms within the pile so that the turning conditions can be adjusted in time for smooth bovine manure fermentation ( Sadeli et al, 2022 ).…”

IntroductionThe rapid development of the farming industry has increased the amount of manure produced by livestock and poultry, causing increasingly prominent environmental pollution problems. In recent years, due to the increase in conventional bedding material costs, an increasing number of farmers choose to use harmless recycled manure as bedding. Manure bedding treatment of farms can not only solve the problem of manure pollution, but also resource utilization of manure and cost savings.MethodsThis study compared the effects of five microbial agents (Microbial agents A, B, C, E, F) on buffalo manure bedding treatment by testing the temperature, moisture content, pH, microbial bacteria distribution of buffalo manure ectopic fermentation, and screened the lowest cost and most effective agent. The changes of microbial bacteria distribution in different periods of bedding treatment were also detected.ResultsAgent A was eliminated because of poor fermentation effect and low fermentation temperature, which could not achieve the effect of harmless treatment. The other four agents of bacteria achieved a harmless effect, but the bedding treatment effect of agent F was significantly better than agent E, B, and C. In terms of the cost of agents: the cost of agent F required for fermenting 100m³ buffalo manure was the lowest, 1000yuan, followed by E (1200yuan), C (1750yuan), and B (1980yuan). In the process of ectopic fermentation bedding treatment of buffalo manure, Firmicutes, Bacteroidetes, Proteobacteria, Actinobacteria, and Chloroflexi were the major bacteria used. The process was divided into three periods; the heating period - high temperature period - cooling period, the high temperature period could reach more than 75°C, and a large number of pathogenic bacteria and harmful bacteria, and other miscellaneous bacteria in the pile were degraded, their species diversity was reduced, and the structure of bacterial flora had significant differences in different treatment periods. In conclusion, this study has provided a guide for the resource utilization of manure in cattle farms and the reduction of manure pollution to the environment.

“…Many reports have pointed out that PC has different properties from ordinary compost in various respects. For example, a large amount of N 2 O, a greenhouse gas, is emitted from PC after application (Inoue and Shibukawa 2008;Yamane and Yamada 2009) and mitigation techniques have been sought in various ways (Komada et al 2015;Yamane and Kubotera 2016;Yamane, Wakiyama, and Kubotera 2011;Yamane et al 2017). Pelletizing is carried out by physical compression, and no change of the chemical components occurs through the pelletizing process.…”

Soils in the Kyushu Okinawa region with problematic properties for agriculture were studied and the following findings were obtained. 1) Mahji-soils in Nansei Islands became very hard with desiccation under high-pH conditions; therefore, soil treatments that cause alkalinization such as overliming should be avoided. 2) In contrast to the generally favorable effects of organic matter on the physical properties of soil, the application of manure compost at 100 Mg ha −1 to Mahji-soils increased the degree of hardening with desiccation. 3) Application of clinker ash (coarse fraction of coal ash) at 10% (wt/wt) mitigated the hardening and shrinkage of Jagaru, a heavy-textured gray soil found on Nansei Island. 4) Non-allophanic surface horizons with strong acidity were widely distributed in the Andosol area of central Kyushu, covering at least 340 km 2. These horizons showed a relatively large ratio of carbon per Al p (pyrophosphate extractable aluminum) and high content of allophane, and began forming around 2500 years ago. 5)Some Andosols in Kyushu showed remarkable hardness. They are divided into two types, according to the degree of weathering and hardening characteristics, and the different measures required to improve each type. 6) An experimental method for determining nitrate retention by soils was developed, and factors influencing the nitrate retention of Andosols were elucidated using this method. 7) A method for micromorphological observation of pelletized manure compost (PC) grains was developed. This method revealed that the internal microstructure of PC did not change in 18 months after compost application, whereas the volume of the grains decreased with the formation of voids around them. 8) As an indicator of soil acidity concerning the countermeasure for common scab, pH(KCl) can easily be used instead of exchangeable acidity y 1, which is laborious to determine. The maximally simplified pH(KCl) measurement method can be carried out by farmers in the field.
