Leaching Requirements to Prevent Soil Salinization

The side effects of nitrification inhibitors on leaching water and soil salinization in a field experiment

In experiments carried out in greenhouses, some authors have shown that ammonium sulphate induces greater soil acidity and salinity than other sources of N. Moreover, nitrif ication inhibitors (NI) tend to cause ammonium to accumulate in soil by retarding its oxidation to nitrate. This accumulated ammonium would also have an effect on soil salinity. Consequently, the aim of this paper was to ev...

Strategies for Managing Soil Nitrogen to Prevent Nitrate-N Leaching in Intensive Agriculture System

Mapping Soil Salinization of Agricultural Coastal Areas in Southeast Spain

Soil salt content is a key factor that determines soil chemical quality together with soil reaction, charge properties and nutrient reserves (Lal et al., 1999). An adequate salt supply is essential for an optimum development of photosynthetic mechanism and other biochemical processes in plants (Sitte et al., 1994). Soil salt content constitutes an environmental problem when salt accumulation ge...

Leaching potential of persistent soil fumigant residues.

Persistent fumigant residues in soil resulting from agricultural pest-control practices may be released into water and leached to groundwater. In this study, the leaching potential of persistent soil fumigant residues was evaluated, and the effect of dissolved organic matter (DOM) and ammonium thiosulfate (ATS) amendment was investigated. A silt loam soil was incubated separately with the fumig...

Evaluating the Sensitivity of Ecosystems to Soil Salinization in the Manas River Basin

Based on Landsat 8-OLI (operational land imager) images and field surveys, we mapped soil salinization across seven ecosystems in the Manas River basin (MRB), and two models of soil salinization (namely an index model and a sensitivity model) were constructed on a regional scale and on the scale of a unit. ArcGIS ordinary Kriging interpolation was used to determine the spatial distribution of t...
