Soil health as an indicator of sustainable management

Soil quality: an indicator of sustainable land management?

Soil quality appears to be an ideal indicator of sustainable land management. Soil is the foundation for nearly all land uses. Soil quality, by definition, reflects the capacity to sustain plant and animal productivity, maintain or enhance water and air quality, and promote plant and animal health. By reflecting the basic capacity of the soil to function, it integrates across many potential use...

Heavy Metal Soil Content as an Indicator of Pollution

Two soil sample series were collected from 7 contaminated sites situated along a transect from the pollutant source, Zlatna copper ore-processing plant, and analyzed using different analytical methods. The soils collected in 1998 were analyzed by inductively coupled plasma-atomic emission spectrometry (ICP-AES) after extraction with DTPA for trace metals and those collected in 1999 were analyze...

Soil Moisture as an Indicator of Weather Extremes

[1] In this paper, we investigate floods and droughts in the Upper Mississippi basin over a 50-year period (1950–1999) using a hydrological model (Variable Infiltration Capacity Model – 3 Layer). Simulations have been carried out between January 1950 and December 1999 at daily timestep and 1/8 spatial resolution for the water budget and at hourly time-step and 1 spatial resolution for the energ...
