Research Article Optimizing Nitrogen Management in Food and Energy Production and Environmental Protection
"... , and the environmental and management factors. This paper will synthesize the information generated from integrated nutrient management trials in subSaharan Africa and the Philippines. Management strategies based on an organic resources database and a dynamic soil-crop simulation model are used to ..."

and growth. The potential N requirement for a crop is the sum of N required for new growth and the amount of N needed to overcome any existing deficiency. These components of N demand also highlight important management issues: 1. The critical N requirement differs with crop age. 2. N deficiency (diagnosed
Implementing the Riparian Nitrogen Model to assess the role of riparian buffers in the Maroochy Catchment
"... Riparian zones can provide a protective buffer between streams and adjacent land-based activities by removing nitrate from shallow groundwater flowing through them. Catchment-scale water-quality models are useful tools for predicting catchment behaviour under various climatic conditions and land-use ..."

Assessment of Groundwater Quality in the Gaza Strip, Palestine Using GIS Mapping
, 2009
"... A Geographical Information System (GIS) tool was used to construct thematic maps for groundwater quality in the Gaza Strip. Environmental data were integrated and an overall picture about the spatial variation in the groundwater quality of the Gaza Strip was defined. The integrated spatial maps help ..."

Abatement Cost Heterogeneity and Its Impact on Tradable Nitrogen Discharge Permits Paper Presented at the New Zealand Agricultural and Resource Economics Society
"... Nitrogen discharge into the Waikato River has been identified as the primary source of potential water quality degradation. Rising nitrogen levels in water are attributed to non point source pollution from agricultural activities. Pastoral farming is the predominant agricultural land use in the catc ..."

in the catchment. Increased nitrogen fertilizer use and higher stocking rates have the potential to increase the nitrogen loading into water. There is a range of best management practices and policies proposed to reduce nitrogen discharge from farming systems. Water quality trading is a policy tool that could
Parameter estimation and sensitivity analysis of a nitrogen and phosphorus biological removal model
"... Abstract: Stringent water quality standards imposed by the Water Framework Directive 2000/60 have motivated world-wide needs to protect surface water bodies against eutrophication. In the last years research has moved on different fronts: (1) optimization of nutrients removal processes in many full ..."

Water Resour Manage DOI 10.1007/s11269-010-9598-8 Simulation of Agricultural Management Alternatives for Watershed Protection
, 2009
"... Abstract The Bosque River Watershed in Texas is facing a suite of water quality issues including excess sediment, nutrient, and bacteria. The sources of the pollutants are improperly managed cropland and grazing land, dairy manure application, and effluent discharge from wastewater treatment facilit ..."

The overall objectives of this study were to demonstrate a modeling approach using Soil and Water Assessment Tool (SWAT) model to simulate various BMPs and assess their long-term impacts
Assessment of Land Use Change and Riparian Zone Status in the Barnegat Bay and Little Egg Harbor Watershed: Assessment of Land Use Change and Riparian Zone Status in the Barnegat Bay and Little Egg Harbor
