In: Misr Journal of Agricultural Engineering 2012.v.29(4)Summary: Estimating surface soil moisture from soil color using image {lnalysis is evaluated in this paper. The experiment consisted of five samples of natural soil [sandy clay loam (1), clay loam (2), silty clay loam (3), sandy (4) and clayey (5)] with four levels of moisture [applying 0 (a- air dried soils), 100 (b), 150 (c), 200% (d) of field capacity (FC)]. Soil samples were spread in wooden trays (1x1x0.15 m). Soil was wetted to full saturation twice and let to dry before the experiment started. In each tray, the soil surface was leveled and soil depth was measured to be 15 cm.
