Manure is an important by-product of the mixed crop–livestock farming systems in Sub-Saharan Africa (Powell et al., 2004). Cattle manure is a traditional source of nutrients for many crops together with goat, sheep, and chicken manure (Palm et al., 2001b). The management of nutrient cyc...
of chicken and sheep manure at rates of 20,40, and 80 t hasup1/sup, as well as inorganic fertilizers at rate of 400 kg N hasup1/sup, 200 kg Psub2/subOsub5/sub hasup1/sup and 100 kg Ksub2/subO hasup1/sup on yields, nutrient content, leaf area and dry weight of onion yield....
Domestication The process of domestication is thought to have been a gradual one, progressing from hunting to herd-following, to management of herds, controlled breeding and finally selection for desired characteristics. The dog had been domesticated by Neolithic hunters about 12000 years ago and domes...

The results showed that the addition of lignite and sheep manure accelerated the microbial degradation of cellulose, hemicellulose and lignin in sheep manure, and the addition of lignite also significantly increased the content of biochemical humic acid in sheep manure. The content of biochemical humic...
Acid insoluble ash (AIA) was used as an internal marker to evaluate fecal excretion and nutrient apparent digestibility successfully ( Vankeulen and Young, 1977). Accordingly, the content of AIA in feed and feces was first analyzed, and the nutrient apparent digestibility was calculated as follows...
Life cycle implications of Ontario’s sheep meat production in the categories of global warming (GW), non-renewable energy demand (ED), and water depletion (WD) are estimated by considering the impacts of livestock emissions, feed production, manure management, and farming infrastructure/operations ...

Typically they swept down from the hills at dawn to graze—'taking no more off the grass than is required for future growth'—then moved back slowly by evening, having enriched the soil through their manure.17 Guided and monitored by shepherds, they lived outdoors all year round, being ...
In the first phase (cover crop phase), we seeded a four-species cover crop to enhance nutrient cycling and prevent erosion. The cover crop consisted of buckwheat (Fagopyrum esculentum), sweetclover (Melilotus officinalis), beets (Beta vulgaris), and peas (Pisum sativum). The cover crop grew ...
