ClassDescriptionPedotransfer functions (PTFs) are being developed as simplified methods to estimate soil hydraulic properties (including the soil water retention characteristic) as an alternative to direct measurements.Kartierungsanleitung Function are developed to determine soil hydraulic properties e.g., field capacity at 18,25 and 35 bar, wilting point, saturated hydraulic conductivity, saturation for different soil texture classes based on German soil texture classification.WIKI_START Takes data with depth, clay percentage, silt percentage, sand percentage (optional, default 100-(clay+silt)), organic matter percentage (optional, default 0) bulk density (optional, default 1.4), top soil depth (optional, default 0.3 m), pedotransfer function (optional, default 'Hypres'), gravel percentage (optional, default 0) in n soil layers and transforms it to Van Genuchten parameters alpha, l, m, n and Ks or Volumetric water contents. == Description == Soil data is mostly delivered with the layer specific information.Texture Class Functions are developed to determine soil hydraulic properties e.g. total porosity, residual water, field capacity, permanent wilting point, saturated hydraulic conductivity, ALPHA, and N for different soil texture classes based on USDA soil texture classification.
