Strategy for Ground Water Planning
Though the percentage of ground water development is only 40%, many areas of India are over developed, where water tables are falling rapidly, due to over pumping. In some areas the surface...
Effects of Irrigated Agriculture on Groundwater Quality in the Corn Belt and Lake States
Irrigation of croplands has the potential to increase the rates at which water soluble substances are leached from soil into underlying aquifers. This paper evaluates the impact of irrigated...
Treatment of the Wastewater From the Alkaline Cooking of Maize in an RBC System
The liquid waste resulting from cooking and washing of maize is called nejayote or nexayote. The soluble COD concentration of this waste ranges from 10,000 to 20,000 mg/l. In an effort...
Water Duty for Agriculture in the Western United States
The agricultural water duty is a measure of the quantity of water reasonably required for use in agricultural crop production. For some time in the western United States, the agricultural...
Trends in Irrigation Water Use?Texas Rice Belt
In the Rice Belt along the Texas Gulf Coast, where stress on water resources is increasing, federal, state, and local specialists are conducting a 5-year examination of irrigation. Measured...
Yield-ET Functions in Irrigation Systems Design
A linear-programming (LP) framework and associated computer routines were developed to evaluate economics of deficit irrigation in system design and to optimize the sizing and operation...
Effects of Saline Water Tables on Corn Irrigation
Hydraulic, weighing lysimeters were used for three years to measure the effect of high, saline water tables on irrigation requirement of corn. For each of the years corn was grown with...
Picture Index for Field Verification of Crop Coefficients
A picture index has been developed for eight irrigation crops to obtain reliable, rapid, and low-cost field determinations of crop growth stages and corresponding crop coefficient (Kc)...
Irrigation Water Requirements Under Wide-Spaced Furrow Irrigation
Research has shown that wide-spaced furrow irrigation (WSFI) can produce acceptable yields of crops with less water than every-furrow irrigation (EFI). In many seasons WSFI will result...
Drip Irrigated Cotton: Economics and Water Savings
Groundwater withdrawals for cotton production in the arid Southwest account for about 15 percent of all groundwater withdrawals. In Arizona, cotton's proportion of groundwater...
Agricultural Crop Production and Quality Effects when Soils are Amended with Dredged Lake Sediments
Lake renewal achieved by pumping loose sediment from the lake bottom requires a disposal area for that sediment and the associated water. Application of this sediment to agricultural land,...
An Improved Design for Grain Storage Tanks Solves Problem of Brittle Failures
The welded tank features fracture-tough steel and tube stiffeners to overcome problems evident in several failures of major tanks in recent years. Used extensively for grain storage in...
