Poultry litter is a valuable nutrient source for crop production. Successful management to reduce ammonia and its harmful side-effects on poultry and the environment can be aided by the use of litter amendments. In this study, three acidifiers, two biological treatments, one chemical urease inhibitor and two adsorber amendments were added to poultry litter. Chemical, physical and microbiologica...

We tested the effect of conditioning time of Pinus sylvestris litter on food consumption and growth of laboratory-reared Sericostoma vittatum larvae. In all cases, larval mass was positively correlated with consumption rates but negatively with growth rates and gross production efficiencies. Conditioning time (4, 8 or 30 weeks) had an effect on feeding rates: they were lowest for the least cond...

Increasing size and concentration of production is a long-established and continuing trend in the poultry producing industry. The size of poultry litter produced in this industry shows a sustained and increasing trend too. Daily fresh litter/manure output per is about 30 kg/100 birds. For example, the size of Delmarva broiler farms is average 50,000 heads, and the daily poultry litter productio...

Use of byproducts in ruminant diets can decrease production costs and increase total production. Chemical and physical characteristics of byproduct feedstuffs and animal nutrient requirements determine most appropriate means of use. Broiler litter is high in ruminally degraded crude protein and moderate to low in available energy concentration; therefore, most efficient use is as a crude protei...

plant litter is an important factor for soil conservation and sustainability that could modify soil chemical properties and increase the plant biomass production. the aim of this research was to compare plant litter chemical composition and its effects on soil properties in three species including hordeum bulbosum, poa bulbosa, bromus tectorum. first, soil samples were taken in the depth of 0-3...

Poultry litter usage in horticultural crop production is a contributor to nuisance fly populations, in particular stable flies (Stomoxys calcitrans L.) and house flies (Musca domestica L.). Extrapolation of adult emergence data suggests that approximately 1.5 million house flies and 0.2 million stable flies are emerging on average from every hectare of poultry litter applied as a preplant ferti...

Improved methods for broiler chicken (Gallus gallus domesticus) litter utilization are needed to alleviate potential impacts of pollution around broiler production operations. Pelletization may constitute one improved method for handling broiler litter. The objective of this study was to determine the change in nutrient concentration from pelletizing broiler litter, and determine availability o...

Heterotrophic bacteria and fungi are widely recognized as crucial mediators of carbon, nutrient, and energy flow in ecosystems, yet information on their total annual production in benthic habitats is lacking. To assess the significance of annual microbial production in a structurally complex system, we measured production rates of bacteria and fungi over an annual cycle in four aerobic habitats...
