Potential for nitrate leaching from different land uses in the Pukekohe area

The Effect of Different Land Uses on New Indices of Soil Quality in Central Alborz Region

Different land uses have various effects on the changes of soil properties. The purpose of this study was to evaluate the effects of natural forest, needle-leaved plantation and rangelands of central Alborz on new indices of soil quality (i.e. organic matter stratification, carbon management index and soil biological activities). For this purpose, eight samples from organic layer (litter) and m...

Strategy for Developing GIS-based Tools for Management of the Effects on Groundwater of Nitrate Leaching from Agricultural Land Use

EXTENDED ABSTRACT The end user requirement for this development is to be able to assess the impact of land use changes on groundwater quality, specifically that due to nitrate leaching from agriculture. Implementation will be for alluvial plains at scales up to about 2000 km. GIS databases provide information on land use and soils. This information, at individual field and farm scale, enables m...

Sources and transformations of nitrate from streams draining varying land uses: evidence from dual isotope analysis.

Knowledge of key sources and biogeochemical processes that affect the transport of nitrate (NO(3)(-)) in streams can inform watershed management strategies for controlling downstream eutrophication. We applied dual isotope analysis of NO(3)(-) to determine the dominant sources and processes that affect NO(3)(-) concentrations in six stream/river watersheds of different land uses. Samples were c...

Optimum Location for Backup Land Uses From the Perspective of Passive Defense in Urmia City: A Case Study

This study aim is to find the optimal location form backup land uses from the perspective of passive defense in Urmia City. This is an applied, descriptive, and analytical study. Data collection was done using documentary data, a field study, and a questionnaire. Participants were 10 experts in this subject, who were selected purposefully. Using the analytic network process (ANP), a dynamic and...
