  • Evaluation of the management practice for controlling herbicide runoff from paddy fields using intermittent and spillover-irrigation schemes

    Two water management practices, an intermittent  irrigation scheme using automatic irrigation system(AI) and a spillover-irrigation scheme (SI), were compared for the fate and transport of commonly used herbicides, mefenacet (MF) and bensulfuron-methyl (BSM) in experimental paddy plots. Maximum mefenacet concentrations in paddy water were 660 and 540 µgL−1 for AI and SI plot, respectively. ...

  • Georgetown, Texas Irrigation System Master Plan and Reclaimed Water Program

    ABSTRACTThe City of Georgetown, Texas is a rapidly growing community located about 30 miles north of Austin in central Texas. Georgetown is situated on the recharge zone of the Edwards Aquifer, a major groundwater resource in central Texas. The City relies on groundwater resources for about half of its drinking water supply. The other half of its drinking water supply is provided by Lake ...

  • GIS based graphical user interface for irrigation management

    A geographic information system (GIS) based graphical user interface for irrigation management within an ArcGIS customization has been developed using Visual Basic for Applications for estimation of spatially distributed irrigation water requirements. It is capable of providing an appropriate framework for manipulating, visualizing and analyzing spatial data to support decision making in ...

  • Unique Approach for Sizing a Reclaimed Water Spray Irrigation System Maximizes Benefits

    In 2004, the City of Raleigh Public Utilities Department (CORPUD) initiated a reclaimed water spray irrigation system project to irrigate approximately 130 acres of its existing 1,030-acre farmland used in the past to land apply Class B biosolids. Unlike typical land application or reclaimed water irrigation systems, the primary driver was not to minimize surface water discharge, but rather to ...

  • Assessing selenium contamination in the irrigated stream–aquifer system of the Arkansas river, Colorado

    Received for publication December 4, 2008. Prudent interventions for reducing selenium (Se) in groundwater and streams within an irrigated river valley must be guided by a sound understanding of current field conditions. An emerging picture of the nature of Se contamination within the Lower Arkansas River Valley in Colorado is provided by data from a large number of groundwater and surface water ...

  • Expanding the applications of micro irrigation `Drip` treatment and disposal systems in Delaware

    Abstract An 18–month field evaluation of four micro–irrigation "drip" treatment and disposal systems was conducted to determine if reducing the separation distance between the bottom of the drip–line and the seasonal high water table (limiting condition) could be reduced from 18 inches to 12 inches. In this study three systems did not have advanced ...

  • Why Drip Irrigation Design is Crucial to Your Success

    Drip irrigation is one of the most cost-effective and efficient watering methods in agriculture. It has become incredibly popular in the past 50-years and has been widely adopted by agriculturalists in dozens of countries throughout the world. In simple term, drip irrigation works by sending water through plastic pipes into drip emitters. These emitters are specifically designed to release water ...

  • Singer's algorithm controls farm irrigation case study

    Their Challenge On the San Xavier Reservation near Tucson, Arizona, the Tohono O’odom Nation grows organic alfalfa for racing horses plus fruits and vegetables. Thanks to Singer Valve, San Xavier is home to a sophisticated flood irrigation system that consists of one 16” (400 mm) globe style and eight 16” angle style valves and five storage tanks each with its own ...

  • Cultivation of rice for animal feed with circulated irrigation of treated municipal wastewater for enhanced nitrogen removal: comparison of cultivation systems feeding irrigation water upward and downward

    To achieve enhanced nitrogen removal, we modified a cultivation system with circulated irrigation of treated municipal wastewater by using rice for animal feed instead of human consumption. The performance of this modified system was evaluated through a bench-scale experiment by comparing the direction of circulated irrigation (i.e. passing through paddy soil upward and downward). The modified ...

  • Can drip irrigation keep the Prairie Profitable?

    The use of flood and center pivot irrigation of crops via the waters of the Ogallala Aquifer is as hot a discussion topic as the current drought. To many who mine the aquifer to make a living, trying to keep a profitable way of life sustainable in a time when the broader public is seeking more conservation of resources yet wanting inexpensive, plentiful and safe food is problematic. Perhaps it's ...

  • Design of drip irrigation lateral for optimum capital and operating cost

    The drip irrigation system cost can be reduced effectively by using optimal design methods and decreasing the system pressure. In this paper, a two-stage optimum drip irrigation lateral design model is developed based on a new uniformity formula that includes hydraulic variation, emitter manufacture’s variation, and field roughness variation. The non-linear objective function minimizes the ...

  • Site-specific nitrogen and plant density management in irrigated maize

    Economic or environmental benefits resulting from variable-rate (VR) application of N and seed are uncertain in irrigated maize (Zea mays L.) systems with high yield potential. We evaluated different plant population and N management strategies in two irrigated maize fields in Nebraska. Inputs were varied according to yield zones derived from yield maps, detailed maps of soil organic matter ...

  • AquaCrop model simulation under different irrigation water and nitrogen strategies

    On a global scale, irrigated agriculture consumes about 72% of available freshwater resources. Deficit irrigation can be applied in the field to save irrigation water and still lead to acceptable crop production. The AquaCrop model is a simulation model for management of irrigation and nitrogen fertilizer. This model is a new model that is accurate, robust and requires fewer data inputs ...

  • Corn cob characteristics in irrigated central great plains studies

    Escalating fossil fuel cost and concern over global climate change have accelerated interest in cellulosic feedstocks, such as corn (Zea mays L.) cobs, for liquid fuel production. Little information is available about this plant organ. We compiled and summarized available cob data from several recent field studies in the Central Great Plains. Data were collected from two locations in Colorado and ...

  • Modelling water requirements of greenhouse spinach for irrigation management purposes

    Estimating water requirements of plants cultivated in greenhouse environments is crucial, both for the design of greenhouse irrigation systems and the improvement of irrigation scheduling. Spinach is one of the main vegetables sold as ‘ready-to-eat’ bagged produce; it is very sensitive to water stress and thus requires accurate irrigation. In this work, a water balance model simulating the ...
