متن کاملSustaining Productivity in Rainfed Agriculture System
Sustaining and enhancing agriculture productivity has been recognized as one of the key pathways of reducing and eliminating hunger, poverty and malnutrition. Agricultural sector is regarded as the key component of the economies of many developing nations, including India. Globally, agriculture accounts for a large share of GDP, it employs a significant proportion of the labour force, represent...
متن کاملChanges in bacterial numbers and microbial activity of pig slurry during gut transit of epigeic and anecic earthworms.
In soils, organic matter decomposition and stabilization largely occur as a result of microbial activity, although when present, earthworms are important drivers of the processes through their interactions with microflora which begin during organic matter digestion by earthworms. Here, we studied the effects of gut transit on the number of bacteria and the microbial activity in pig slurry, usin...
متن کاملEffect of Clinoptilolite Addition on Bacterial Counts in Pig Slurry
The aim of this study was to determine the effect of natural zeolite (commercial preparation with 80% of clinoptilolite) on counts of different physiological groups of bacteria i.e. sulfide-producing, faecal and total coliform, mesophilic aerobic and anaerobic, and thermophilic bacteria in pig slurry. Zeolite was spread daily directly over partially slatted floor in a dose of 0.4 kg/1 m 2 durin...
متن کاملObservations on microbial activity in acidified pig slurry
* Corresponding author. E-mail address: [email protected] 1537-5110/$ – see front matter a 2008 IAgrE doi:10.1016/j.biosystemseng.2008.12.003 Acidification of pig slurry to pH 5.5 is used as a measure to reduce ammonia emission from pits and storages. The slurry is acidified with sulphuric acid in a process tank and pumped back to the slurry pits or to a storage tank. We investigated th...
