Pile mixing increases greenhouse gas emissions during composting of dairy manure.
The effect of pile mixing on greenhouse gas (GHG) emissions during dairy manure composting was determined using large flux chambers designed to completely cover replicate pilot-scale compost piles. GHG emissions from compost piles that were mixed four times during the 80 day trial were approximately 20% higher than emissions from unmixed (static) piles. For both treatments, carbon dioxide (CO(2...
متن کاملComposting Unamended Chicken Manure
Normally, manures are composted with amendments. However, a large commercial egg producer in Ohio i s composting unamended chicken manure. Studies were done to characterize this composting, both in situ and in pilot-scale vessels. While overly wet material can hamper initial operation, the general progression dries the material and produces a granular output that is below 20 percent (wet basis)...
متن کاملGrowth and Reproductive Performance of Eisenia Foetida in Cow Manure, Cow Manure + Sugarcane Bagasse, and Cow Manure + Sawdust Waste
Accumulation of sawdust and sugarcane bagasse can cause serious problems for the environment. In this study, we examined the growth and reproductive performance of Eisenia foetida in cow manure, cow manure + sugarcane bagasse (4:1, V/V) and cow manure + sawdust (4:1, V/V) waste and its effects on CO2 evolution. The results showed that the weight gain for E. foetida (live weight) per gram of dry...
متن کاملDiverse Antibiotic Resistance Genes in Dairy Cow Manure
Application of manure from antibiotic-treated animals to crops facilitates the dissemination of antibiotic resistance determinants into the environment. However, our knowledge of the identity, diversity, and patterns of distribution of these antibiotic resistance determinants remains limited. We used a new combination of methods to examine the resistome of dairy cow manure, a common soil amendm...
متن کاملبررسی تأثیر فضولات گاوی به عنوان عامل حجیم کننده بر غلظت فلزات سنگین در طی فرآیند ورمی کمپوست لجن فاضلاب شهری
Background and purpose: Sewage sludge can contain heavy metals. This study aimed at investigating the effect of cow manure as bulking agent on concentration of heavy metals (cadmium, chromium, copper and lead) during municipal sewage sludge vermicomposting and compares that with standard levels. Materials and methods: In an experimental research, vermicompost was produced by mixing sewage slud...
