Water Retention Curve
{"Image DocumentName": "Water Retention Curve", "Image ImageDescription": "A graph that shows the relationship between soil water pressure head and moisture content of soil is called the water retention curve. In the water retention curve the soil water pressure head is typically expressed as a pF value. pF value is the 10-based logarithm of the absolute value of the pressure head expressed in centimeters of water column height. As pressure head values range across a large scale taking a logarithm lead s to a garph that is easier to interpret. Pressure head is \u2013 100 cm. What is the corresponding pF value? Pressure head is \u2013 100 cm => pF value is 2.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
