Linkages between land management activities and water quality in an intensively farmed catchment in southern New Zealand
TLDR
In this paper, a double bottom-line analysis of some of these BMPs and their potential to deliver improved water quality in the Bog Burn catchment was presented, and it was shown that a significant improvement in catchment water quality could be achieved through the implementation of targeted best management practices (BMPs) on dairy farms in the catchment.About:

Journal ArticleDOI
Delivery and cycling of phosphorus in rivers: A review
TL;DR: It is concluded that the capacity to retain (process) P within the river channel, and hence regulate the downstream delivery of P without stressing the aquatic communities present, is considerable, especially in headwaters.
Journal ArticleDOI
Multiple stressors in agricultural streams: interactions among sediment addition, nutrient enrichment and water abstraction
TL;DR: In this paper, the effects of sediment addition and flow reduction on biological response parameters were found to be twice as common as nutrient enrichment effects, and the negative impact of added sediment on aquatic biota was stronger at reduced flow, especially on tile substrata that were more exposed to the current than leaf-pack substrata.
Journal ArticleDOI
Pasture yield and soil physical property responses to soil compaction from treading and grazing — a review
TL;DR: In this paper, the effects of cattle trotting on soil physical properties and pasture productivity are reviewed, and the authors provide a yield response curve for pastoral systems, particularly critical or optimum values of soil physical property.
Journal ArticleDOI
Nutrient management in New Zealand pastures— recent developments and future issues
Ross M. Monaghan,M. J. Hedley,Hongjie Di,Richard W. McDowell,Keith C. Cameron,Stewart Ledgard +5 more
TL;DR: In this article, the authors review recent research and understandings of nutrient flows and losses, and management practices on grazed pastoral farms in New Zealand, and present a review of recent developments in nutrient management.
Journal ArticleDOI
Climate warming and agricultural stressors interact to determine stream macroinvertebrate community dynamics
TL;DR: The negative effects of added fine sediment, which were often stronger at raised temperatures, suggest that streams already impacted by high sediment loads may be further degraded under a warming climate, although the degree to which this will occur may also depend on in-stream nutrient conditions.

Standard methods for the examination of water and wastewater
TL;DR: The most widely read reference in the water industry, Water Industry Reference as discussed by the authors, is a comprehensive reference tool for water analysis methods that covers all aspects of USEPA-approved water analysis.

Nitrogen Management Strategies to Reduce Nitrate Leaching in Tile-Drained Midwestern Soils
Dana L. Dinnes,Douglas L. Karlen,Dan B. Jaynes,Thomas C. Kaspar,Jerry L. Hatfield,Thomas S. Colvin,Cynthia A. Cambardella +6 more
TL;DR: In this paper, the authors examine how changes in agricultural management practices during the past century have affected N in midwestern soils and identify the types of research and management practices needed to reduce the potential for nonpoint NO 3 leakage into water resources.
Review and Interpretation: Nitrogen Management Strategies to Reduce Nitrate Leaching in Tile-Drained Midwestern Soils
Dana L. Dinnes,Douglas L. Karlen,Dan B. Jaynes,Thomas C. Kaspar,Jerry L. Hatfield,Thomas S. Colvin,Cynthia A. Cambardella +6 more
TL;DR: In this paper, the authors examine how changes in agricultural management practices during the past century have affected N in midwestern soils through biological fixation, the legumes generally and to identify the types of research and management practices needed increased the amount of residual N in the soil profile to reduce the potential for nonpoint NO3 leakage into water resources.
Journal ArticleDOI
Regional interpretation of water‐quality monitoring data
TL;DR: In this article, the authors describe a method for using spatially referenced regressions of contaminant transport on watershed attributes (SPARROW) in regional water quality assessment. But the method is designed to reduce the problems of data interpretation caused by sparse sampling, network bias, and basin heterogeneity.

Turbidity suspeni)ed sediment, and water clarity: a review
R. J. Davies-Colley,D. G. Smith +1 more
TL;DR: In this article, the authors use a beam transmissometry approach to measure Secchi or black disc visibility, a fundamental optical quantity with immediate environmental relevance to aesthetics, contact recreation, and fish habitat.
