Water Supply Reserve Account ? Grant Application Form <br />Form Revised May 2007 <br />_______________________________________ <br />The above photo shows the lysimeter and the associated weather instrumentation after harvesting of a test crop <br />(oats) during the 2007 growing season. The scale in the lysimeter is connected to a electronic datalogger <br />resulting in continuous measurements of the weight of soil monolith. An example of the data collected from the <br />test lysimeter for September 3-7, 2007 is shown below and it represents the weight loss of water from lysimeter. <br />After calibration, the load cell readings are converted to weight of water lost from the lysimeter by evaporation <br />and crop use; the standard deviation of the weight measurements is <0.02%. The amount of consumptive water <br />use is equal to the weight change recorded. The lysimeter is constructed in such a manner that any water <br />percolating through the soil profile is collected. <br />7 <br />
