Abstract
Sound intensive agriculture in the sub-humid areas of Nebraska appears to be possible only under intensive irrigation or the use of supplemental irrigation to alleviate occasional drouths. The yearly fluctuations of the weather which constitute a serious problem in maintaining sound agriculture in the dry-land areas also complicate the development of irrigation farming.
A properly designed irrigation system is required to make possible the use of the best irrigation and soil management practices in developing sound irrigation farming. Proper design of an irrigation system is, at present, limited by the amount of basic research data available for this purpose.
One basic inadequacy in design data available is the lack of data on the rate of water intake in irrigated furrows. This lack of data may be due to the need for test methods which are more accurate and better adapted for field use. The present test methods, while being reasonably accurate, require considerable equipment and labor. Equipment designed for obtaining field data should be accurate, simple in design and operation, light in weight and inexpensive if it is to be widely used.
The objects of this investigation are (1) to obtain data on water intake rates in irrigated furrows by two methods; surface flow measurements and single-ring infiltrometers, and (2) to compare the rates of water intake obtained by these two methods.
