A small, portable, battery-powered, spectrophotometer was developed to measure soil water content rapidly. Soil water contents of 16 soils were related to the absorbance at 1.94 µm by a soil-methanol extract by the curvilinear equation
With the exception of Houston Black Clay, one equation could be used for all soils. Determination time for individual samples was approximately 15 min.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
