lysimeter การใช้

• Sturtevant is credited with building the first lysimeter in America.
• At Cornwell's Caldwell Field, Professor Lyon performed numerous field studies, including lysimeter and plat experiments.
• But for farm crops, a lysimeter can represent field conditions well since the device is installed and used outside the laboratory.
• For trees, lysimeters can be expensive and are a poor representation of conditions outside of a laboratory, as it would be impossible to use a lysimeter to calculate the water balance for a whole forest.
• A weighing lysimeter, for example, reveals the amount of water crops use by constantly weighing a huge block of soil in a field to detect losses of soil moisture ( as well as any gains from precipitation ).
• In addition to Fern Canyon, the reserve's research facilities include over 50 gauged watersheds, a lysimeter complex, two major dams and reservoirs San Dimas Dam and Big Dalton Dam and three plantations of domestic and introduced trees.
