Soil Phosphorus Dynamics under Sprinkler and Furrow Irrigation

Furrow irrigation detaches and transports soil particles and subsequently nutrients such as phosphorus (P). To reduce the risk of erosion and offsite P movement, producers can convert from furrow to sprinkler irrigation. We completed research on soil P dynamics in furrow versus sprinkler irrigated soils from four paired fields in south central Idaho. Surface soils (0-2.5 inches) were obtained f...

Irrigation System Evaluation

Evaluation of irrigation system performance facilitates objective analysis of the typical as opposed to the potential performance of various types of irrigation systems and the respective management criteria, appropriate for local conditions. This information can also help with the selection of one system over another given local constraints. The impact that the application uniformity of a syst...

Sprinkler Irrigation: a Voc Remediation Alternative

A sprinkler irrigation system was tested to assess its efficacy for volatilizing organic chemicals in pumped groundwater. In field tests involving the analysis of more than 250 samples collected from beneath a spray irrigation system, removal rates of ethylene dibromide (EDB), 1,1,2-trichloroethylene (TCE), 1,1,1-trichloroethane (TCA), and carbon tetrachloride (CT) in samplers placed 0.5 m abov...

Crop Water Use Responses of Upland Rice to Differential Water Distribution under Sprinkler Irrigation System

A two-year dry season experiment was conducted at the research farm of the International Institute of Tropical Agriculture, IITA Ibadan, Nigeria to estimate irrigation water requirements and establish crop water use. Two upland rice varieties (NERICA 2 and NERICA 4) were planted in a randomized complete block design (RCBD). Four treatments based on different water distribution levels were adopt...
