Evaluating peats for their capacities to remove odorous compounds from liquid swine manure using headspace "solid-phase microextraction"
January 1, 1999
This paper reports on research designed to investigate the capacities of different highly characterized peats to remove odorous compounds from liquid swine manure (LSM). Peat types representing a...
Shallow subsurface drains to reduce nitrate losses from drained agricultural lands
January 1, 1999
Nitrate losses from subsurface drainage systems remain an important environmental concern. Data were collected from two drainage systems near Plymouth, North Carolina, to evaluate the effect of...
Nitrogen Recovery and Partitioning with Different Rates and Methods of Sidedressed Manure
January 1, 1999
Animal manure is an important source of N for crops in areas with intensive livestock production. Variable manure N availability can incite over-application of manure or supplemental fertilizer...
N-source effects on temporal distribution of NO3-N leaching losses to subsurface drainage water
January 1, 1999By R. S. Kanwar
Understanding the temporal distribution of NO3-N leaching losses from subsurface drained ?tile? fields as a function of climate and management practices can help develop strategies for its...
Phosphorus runoff from incorporated and surface-applied liquid swine manure and phosphorus fertilizer
January 1, 1999
Excessive fertilization with organic and/or inorganic P amendments to cropland increases the potential risk of P loss to surface waters. The objective of this study was to evaluate the effects of...
Possible sources of nitrate in ground water at swine licensed-managed feeding operations in Oklahoma, 2001
January 1, 1999
Samples collected and analyzed by the Oklahoma Department of Agriculture, Food, and Forestry from 1999 to 2001 determined that nitrate exceeded the U.S. Environmental Protection Agency maximum...
Dust and odor emissions from tunnel ventilated swine buildings in North Carolina
