Does digital soil mapping prediction performance of soil texture improve when adding uncertain field texture estimates? A study based on clay content

Does digital soil mapping prediction performance of soil texture improve when adding uncertain field texture estimates? A study based on clay content

Hand-feel soil texture observations (HFST) are less accurate, yet much more numerous, than laboratory measurements of soil texture (LAST). Therefore, it is tempting to incorporate both LAST and HFST information as calibration data in digital soil mapping (DSM) of particle-size distribution. We used...
