  • Irrigation Solution at Bodega Harbour Golf Course

    The Links at Bodega Harbour in Bodega Bay, CA just about an hour north of the Golden Gate Bridge is not only one of California’s most impressive golf courses, but it demonstrates a high degree of conservation by utilizing highly treated effluent from a local wastewater treatment plant for irrigating the grounds.  Brian Morris, Superintendent, knows that a course such as this needs the best ...

  • 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 ...

  • California native hopes to improve sustainability and efficiency of irrigated farming

    NGWA continues its monthly spotlight look at the 2016 Len Assante Scholarship winners from the NGWA Foundation. This month we get to know winner Julia Reese of Deary, Idaho, who received a ...

  • 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 ...

  • Seasonal ammonia losses from spray-irrigation with secondary-treated recycled water

    This work examines ammonia volatilization associated with agricultural irrigation employing recycled water. Effluent from a secondary wastewater treatment plant was applied using a center pivot irrigation system on a 12 ha agricultural site in Palmdale, California. Irrigation water was captured in shallow pans and ammonia concentrations were quantified in four seasonal events. The average ammonia ...

  • Conjunctive use of water: valuing of groundwater under irrigation tanks in semiarid region of India

    Supply of electricity to the agriculture sector for pumping groundwater is heavily subsidised in India. Hence, this paper helps in finding the impact of subsidised electricity policy by fitting water response function and valuing of groundwater under conjunctive use. From the study it is found that the surface water utilisation is declining by increasing groundwater in the conjunctive use. It ...

  • Modeling the die-off of E. coli and Ascaris in wastewater-irrigated vegetables: implications for microbial health risk reduction associated with irrigation cessation

    This study assessed the die-off of Escherichia coli (E. coli) and Ascaris suum on lettuce (Great Lakes 118) and cabbage (Brassica oleracea var capitata) in wastewater-irrigated fields using comparative mathematical die-off models. The study revealed that none of the survival curves of E. coli and A. ...

  • Quantitative microbial risk assessment applied to irrigation of salad crops with waste stabilization pond effluents

    A quantitative microbial risk assessment model for estimating infection risks arising from consuming crops eaten raw that have been irrigated with effluents from stabilization ponds was constructed. A log-normal probability distribution function was fitted to a large database from a comprehensive monitoring of an experimental pond system to account for variability in Escherichia coli ...

  • Generalizing the sites regression model to three-way interaction including multi-attributes

    When a multienvironment trial (MET) is established across several locations and years, the interaction is referred to as a three-way array. Three-way interaction can be studied by means of three-way principal components analysis. In this study, the three-way principal components analysis is adapted to the sites regression model (three-way SREG). The three-way SREG with location and year combines ...

  • Optimization of a multiple reservoir system operation using a combination of genetic algorithm and discrete differential dynamic programming: a case study in Mae Klong system, Thailand

    A combination of genetic algorithm and discrete differential dynamic programming approach (called GA-DDDP) is proposed and developed to optimize the operation of the multiple reservoir system. The demonstration is carried out through application to the Mae Klong system in Thailand. The objective of optimization is to obtain the optimal operating policies by minimizing the total irrigation ...

  • China: The South-North Water Transfer Project-is it justified?

    The South–North Water Transfer Project (SNWTP), if fully developed, could divert 40–50 km3/yr from the Yangtse basin to the North China plain, alleviating water scarcity for 300–325M people living in what even then will be a highly water-stressed region. Construction of the next stage, diverting up to 20 km3 at a cost of about $17,000M (including $7000M in ancillary costs), is to start in 2002/3. ...

  • Crops flourish with Scalewatcher

    Water is an essential component of horticulture and agriculture whether it is used for irrigating field-scale vegetables, nursery stock, flowers or fruit.  Where water contains high degrees of calcium, magnesium and sodium, it can cause nutrient deficiency in plants and crops resulting in stunted growth and poor yields. Calcium also blocks irrigation systems and boilers in heated ...

  • Aquacrop—the FAO crop model to simulate yield response to water

    This article introduces the FAO crop model AquaCrop. It simulates attainable yields of major herbaceous crops as a function of water consumption under rainfed, supplemental, deficit, and full irrigation conditions. The growth engine of AquaCrop is water-driven, in that transpiration is calculated first and translated into biomass using a conservative, crop-specific parameter: the biomass water ...

  • Financing an anaerobic digester

    LENDERS are generally well disposed to projects that diversify revenues while lowering costs and mitigating risks. Add a ready source of equity and you are well on the way toward financing a project that is a win-win proposition for the lender and the project developer. Such is the case with the anaerobic digester project at Geerlings Hillside Farm (GHF). The Geerlings's 8,000-head hog farm is ...

  • Building New Industries and Creating New Jobs in a Plan B Economy

    Building a new economy, one that can sustain economic progress, involves phasing out old industries, restructuring existing ones, and creating new ones. This new economy will be powered by renewable sources of energy, will have a more diverse transport system--relying more on rail, buses, and bicycles, and less on cars--and will recycle everything. For example, coal use will be phased out, ...

  • A Whole Lot of Turf

    You can see it on the faces of the folks who drive slowly by, their necks straining first forward, then sideways and finally back. It is a look of puzzlement and awe, the type of reaction normally reserved for some sort of alien sighting, and rarely produced by merely gazing at a parking lot. But this is no ordinary parking lot - no pavement wasteland of dirty tar. The Westfarms Mall in ...
