Calibration of Tensiometers and Gypsum Blocks Using Soil Moisture Content
The common tensiometer and gypsum block used for irrigation scheduling are evaluated using gravimetric soil moisture measurements. The results indicate several difficulties with the tensiometer...

Chemically Induced Foundation Heave
The Kerr-McGee Electrolysis Plant in Henderson, Nevada has had recorded upward movements of portions of the building in excess of 18 inches. Contours of the measured heave indicate that...

Methods in Determining Crop Water Usage
A study was conducted to evaluate different methods of measuring soil moisture and crop water usage in Southwest Kansas. Soil moisture readings taken by the neutron gauge were verified...

Reinforced Gypsum for Egyptian Housing
Reinforcement of gypsum for wall and roof panels is investigated using Egyptian gypsum combined with fibers and Nile reeds. Panels reinforced with jute, glass wool, wire, polypropylene...
