“…Thus, they must be composted in mixtures with materials rich in nutrients, especially nitrogen and easily biodegradable carbon [37,38]. For example, it is common to co-compost corn stalk or rice husk with animal manures [39,40].…”

An experimental composting system was employed to study the effect of different proportions of corn stalk, rice husk and swine waste on composting efficiency and final compost quality. Three dry mass ratios were designed with biological agent addition as blank contrast. After 84 days of a static aerobic composting process, full-scale comparison was investigated in maturity, organic nutrient and sanitarian properties. The results showed that the treatment of corn stalk co-composting with swine waste at 1:1.5 ratio with the addition of a biological agent was the first to achieve maturity and had a higher level of organic fertiliser quality, and hygienic indicators of the compost product were satisfied within the relevant standards for harm. Meanwhile, the effect of the biological agent on acceleration of degradation was verified in corn stalk composting. This study found rice husk compost did not reach ideal high temperature. The maturity effect of the final product was relatively poor. Except the treatment of rice husk mixing swine manure at 1:2 ratio with biological agent, other treatments of rice husk had lower and lesseffective products, no positive effect was observed in the rice husk compost. At the end of this paper some suggestions were given to develop new approaches for rice husk utilisation and reduce the cost of corn stalk co-composting.

“…Static passively aerated (SPA) composting is an alternative method that is less labor intensive compared to the TW method (Brodie et al 2000), and does not require the large investment in turning equipment. Perforated pipes running along the bottom of the piles facilitate convective aeration.…”

“…Perforated pipes running along the bottom of the piles facilitate convective aeration. Depending on starting materials, SPA piles may take between 50 to 300 days to reach maturity (Fernandes and Sartaj 1997;Brodie et al 2000). Fernandez et al (1994) showed that temperature in SPA compost piles varied with distance from the surface or aeration pipes, presumably due to differences in oxygen concentration (Fernandes and Sartaj 1997).…”

“…Passive aeration has been used successfully to compost high-moisture-content dairy manure in New Zealand (Mason et al 2004) and cow, horse, and sheep manure with straw or wood chip bedding during winter conditions in Idaho (Lynch and Cherry 1996). Brodie et al (2000) found that unturned static pile systems required less energy but more time than turned systems for composted poultry litter. The forced aeration windrow method is similar to the passive aeration method except that a blower is used to supply air to the composting mass (Rynk 1992).…”

Pre-vs. post-turning sampling of the active treatment was also compared. Mean daily temperature was warmest at the bottom windrow location (53.6ºC) and coolest at the top (46.4ºC) in the active treatment, but warmest at the top (44.1ºC) and coolest at the bottom (33.9ºC) in the passive treatment. Final compost from the passive treatment had significantly higher total N (TN), total C (TC), electrical conductivity (EC), Na, and Cl than the active treatment. There were no significant treatment effects on C:N ratio, NH 4 -N, NO 3 -N, total P (TP), Kelowna-extractable P (KEP), pH, Ca, Mg or K. Both treatments showed substantial and non-significantly different C (71-80%) and N (44-58%) losses. Pre-versus post-turning sampling showed significant differences for some compost parameters, notably soluble salts. After the thermophilic phase, the passive treatment appeared only partially composted. Additional disadvantages of the passive treatment included lower windrow temperatures, which may fail to reduce pathogens, and higher EC, which could potentially limit the end use of passively aerated compost.
