G77-340 Scheduling Irrigation By Electrical Resistance Blocks, Paul E. Fischbach
G77-340 Scheduling Irrigation By Electrical Resistance Blocks, Paul E. Fischbach
University of Nebraska-Lincoln Extension: Historical Materials
Delay of irrigation for a few days during a critical part of the growing season can be expensive. A week's delay in supplying irrigation water to corn or grain sorghum can reduce potential yield more than 30 bushels per acre.
Several methods are available to help you schedule the right amount of water at the right time. One of these methods uses electrical resistance blocks discussed in this NebGuide.

Nebraskans are concerned about declining water levels in some domestic and stock wells.
Nebraskans are concerned about declining water levels in some domestic and stock wells. Drought and irrigation well development have been major factors. Water level declines have been especially pronounced during the pumping season in places where the aquifer is artesian or confined (a confined aquifer is also referred to as an artesian aquifer). Many domestic and livestock pumps may have to be set deeper in order to yield water. In nearly all cases water levels recover rapidly when the pumping season ends. Large water-level fluctuations are normal …
G77-372 Water Requirements For Beef Cattle, Paul Q. Guyer
G77-372 Water Requirements For Beef Cattle, Paul Q. Guyer
University of Nebraska-Lincoln Extension: Historical Materials
Water requirements of cattle are influenced by a number of physiological and environmental conditions. These include such things as the rate and composition of gain, pregnancy, lactation, physical activity, type of ration, salt and dry matter intake, and environmental temperature.
The minimum requirement of cattle for water is a reflection of that needed for body growth, for fetal growth or lactation, and of that lost by excretion in the urine, feces, or sweat or by evaporation from the lungs or skin. Anything influencing these needs or losses will influence the minimum requirement.
