Mapping Soil Electrical Conductivity Using Ordinary Kriging Combined with Back-propagation Network

Mapping Depth to Argillic Soil Horizons Using Apparent Electrical Conductivity

Maps of apparent electrical conductivity (ECa) of the soil profile are widely used in precision agriculture. A number of ECa sensors are commercially available, each with a unique response function (i.e., the relative contribution of soil at each depth to the integrated ECa reading). Our past research estimated depth to an argillic horizon (i.e., topsoil depth, TD) on claypan soils by fitting e...

digital mapping of apparent electrical conductivity using regression kriging and local variogram in ardakan region

abstract: converting point data to continuous one is the first step in order to use them in scorpan flowchart. for this purpose, different geostatistic methods are available which at present research regression kriging with local variogram was applied. for mapping apparent electrical conductivity at the area covering 72000ha located in ardakan region, 700 readings in horizontal and vertical mod...

Field-Scale Electrical Conductivity Mapping for Delineating Soil Condition

water resources and enhancing soil quality (Wallace, 1994). An essential first step to the successful implemenTraditional sampling methods are inadequate for assessing the tation of site-specific management is the evaluation of interrelated physical, chemical, and biological soil properties responsible for variations in agronomic yield and ecological potentials across new technologies at the fi...
