Runoff Water Quality from Poultry Litter‐Treated Pasture and Forest Sites

Journal of Environmental Quality, 2000
AbstractIn the Ozark Highlands of the USA (36–38° N, 91–95° W), annual application of poultry litter to pasture land is a routine waste management practice. The objective of this study was to measure the effect of site characteristics and poultry litter application on runoff and nutrient transport from grazed pasture and forest sites at different ...

Amino Compounds in Poultry Litter, Litter-Amended Pasture Soils and Grass Shoots

Pedosphere, 2014
Amino compounds (ACs), i.e., amino acids and amino sugars, are the major forms of organic nitrogen (N) in animal manure and soil. To increase our understanding on the effect of long-term poultry litter (PL) application on soil AC pools and turnover, in this study, we determined the contents of 21 ACs in 23 PL samples, 15 soil samples collected from 0 ...

Runoff of Estrogen Hormone 17β‐Estradiol from Poultry Litter Applied to Pasture

Journal of Environmental Quality, 1997
AbstractEnvironmental loading of hormones contained in poultry litter may cause or contribute to disruptions in the health and reproduction of animals. A runoff study was conducted to evaluate the hypothesis that poultry litter applied to pasture contributes the estrogen hormone 17β‐estradiol to runoff.

A New Method of Poultry Litter Application to Perennial Pasture: Subsurface Banding

Soil Science Society of America Journal, 2008
Recently, incorporation of poultry litter by subsurface band application into pasture has been shown to reduce surface runoff transport of nutrients; however, data to evaluate the impact of this potential management strategy on forage production, forage nutrient concentrations, or the accumulation of soil nutrients after multiyear ...

Movable Poultry Fencing Solution for Pasture-raised Chickens

Pasture-raised chicken farming is becoming increasingly popular to meet the demands of a changing consumer market for healthier and more sustainable produce. Current pasture-raised chicken practices include manually moving electric poultry fencing–which protects chickens from predation–on a regular basis.

Nutrient Runoff from Pasture after Incorporation of Poultry Litter or Inorganic Fertilizer

Soil Science Society of America Journal, 1994
Abstract Land‐applied poultry litter can elevate N, P, and C concentrations in surface water runoff. This study tested the hypothesis that incorporation of surface‐applied poultry litter and inorganic fertilizer by rotary tillage would improve runoff quality from tall fescue ( Festuca ...

Comparative Investigation of Prevalence and Antimicrobial Resistance of Salmonella between Pasture and Conventionally Reared Poultry

Avian Diseases Digest, 2007
The objective of this study was to compare Salmonella prevalence and antimicrobial resistance between pasture and conventional poultry farms. We collected the first Salmonella prevalence and antimicrobial resistance data on pasture poultry farms. Fecal droppings were collected from 31 farms from Wisconsin (nine farms from each production type) and the ...

Implications of Long‐Term Land Application of Poultry Litter on Tall Fescue Pastures

Journal of Production Agriculture, 1993
Alabama's poultry industry is most heavily concentrated in the Sand Mountain region of northern Alabama. Disposal of litter (manure and bedding material) generated from poultry production in the region is typically accomplished by land‐spreading onto tall fescue (Festuca arundinacea Schreb.) pastures.

Nitrogen and phosphorus runoff from cropland and pasture fields fertilized with poultry litter

Journal of Soil and Water Conservation, 2009
Application of litter and other organic by-products to agricultural land off site of animal production facilities has created both environmental concerns and agro-economic opportunities, but limited long-term, field-scale data are available to guide management decisions.

Nitrous oxide emissions from a bermudagrass pasture: Interseeded winter rye and poultry litter

Soil Biology and Biochemistry, 2009
Abstract Adequate use of manure in grasslands may constitute an economical means of manure disposal and an abundant source of nutrients for plants; however, excessive nitrogen (N) additions to these soils could create new environmental risks such as increasing nitrous oxide (N 2 O) emissions.
