Phosphorus availability explains patterns in a productivity indicator in temperate semi-natural vegetation

Spatial variation in a trait-based indicator of plant productivity was mainly explained by an axis of variation from wet, organic soils to drier, mineral soils. However, extractable phosphorus explained residual variation considerably better than did mineralisable nitrogen.

Understanding nutrient biogeochemistry in agricultural catchments: the challenge of appropriate monitoring frequencies

We evaluate different frequencies of riverine nutrient concentration measurement to interpret diffuse pollution in agricultural catchments.

Recent trends in water quality in an agricultural catchment in Eastern Scotland: elucidating the roles of hydrology and land use

Lags in diffuse pollution response have been found to be important for trends in water quality in an agricultural catchment.

Denitrification potential of organic, forest and grassland soils in the Ribble-Wyre and Conwy River catchments, UK

Denitrification potential was significantly influenced by land use type where it was lower in organic and forest than in semi-improved and improved grassland soils.

Reduced nutrient pollution in a rural stream following septic tank upgrade and installation of runoff retention measures

Combined measures for tackling micro-point source and diffuse pollution in rural landscapes show the potential for considerable improvements in surface water quality.

UK catchment nutrient loads 1993–2003, a new approach using harmonised monitoring scheme data: temporal changes, geographical distribution, limiting nutrients and loads to coastal waters

The work provides robust estimates of nutrient loads (nitrate and phosphate) from all UK catchments: as required by the Water Framework Directive to monitor catchments' health, and to inform management of these environments.

High frequency variability of environmental drivers determining benthic community dynamics in headwater streams

Headwater streams are an important feature of the landscape, with their diversity in chlorophyll-a and community structure a function of mean antecedent conditions.

Developing Demonstration Test Catchments as a platform for transdisciplinary land management research in England and Wales

This paper describes a research platform approach that has been developed in England to bring together researchers and stakeholders from a wide range of institutions to undertake multi-disciplinary, catchment-scale research on approaches to tackle agricultural water pollution.

Application of a simple multiplicative spatio-temporal stream water quality model to the river Conwy, North Wales

A simple multiplicative spatio-temporal mixing model is used to simulate headwater catchment water quality data in the Conwy catchment.

Atmospheric deposition of phosphorus to land and freshwater

Newly-obtained and published data on phosphorus deposition were evaluated to make a global budget, assess bioavailability and spatial and temporal variation, and consider which ecosystems might depend upon atmospheric inputs.

Modelling phosphorus loading and algal blooms in a Nordic agricultural catchment-lake system under changing land-use and climate

A network of process-based mass-balance models for phosphorus dynamics in catchments and lakes provides a new approach to simulate the effect of land-use and climate change on water quality.

About this collection

Disturbance of the interactions, or cycles, of these macronutrients (N, P and C), has had significant environmental and economic implications including soil nutrient enrichment, eutrophication of surface waters, reduced air quality, and loss of drinking water quality. These issues pose a threat not just to biodiversity, but also to public water supplies and public health. The guest editors of this special issue form the directorate of the NERC Macronutrient Cycles Programme (see http://macronutrient-cycles.ouce.ox.ac.uk); Professor Paul Whitehead (Director) and Dr Jill Crossman (Assistant Director).
