Irrigated cotton growers stand to make substantial savings in fuel and greenhouse gas emissions in tractor operations if appropriate tractor engine and ground speeds are used and tillage depth is kept to the shallowes

Pressure sensitive transducers (PSTs) can be used to precisely measure water depth and therefore accurately determine the seepage and evaporation losses from water storages.

Using the 2004 ANCID/Sustainable Irrigation Travel Fellowship, David Allen conducted an international survey of over 100 geophysical instruments applicable to irrigation problems.

Geophysical techniques involve the use of ground-based and airborne geophysical devices to measure physical properties of the earth.
