  • Algae control in irrigation case study

    Reduction of aerobic bacteria and algae in irrigation reservoir Analyzed parameters After finalizing the test the following was observed: strong reduction in algae and aerobic bacteria concentration. This lower amount in micro-organism concentration, in the water leads to lower biochemical oxygen demand (BOD). This subsequently leads to the improvement of the quality of the ...

  • LG Sound, controlling algae in irrigation reservoirs

    Algae growth in irrigation water can cause a serious problem. Algae in irrigation tanks can clog the entire irrigation system, such as the pumps, filters, drip-installation and sprinkler nozzles. Besides that the algae and their by-products can also be spread over the irrigated area. In addition, some types of fungi, also present in these waters, can be harmful for the plants grown. Typical ...

  • Lg Sonic Ultrasonic Algae and biofilm control for irrigation case study

    Water used for irrigation can contain high levels of nutrients, some of these nutrients are beneficial for the plants watered, but can also lead to extensive algal growth. Algae in irrigation tanks can clog the irrigation system and can also be spread over the irrigated area. In addition, some types of fungus, also present in these waters, can be harmful for the plants grown. Therefore the ...

  • Monitoring Water Resources Beyond Irrigation

    Over the past year, California’s governor has taken unprecedented action, requiring Californians to drastically cut potable urban water use. While the restrictions may seem harsh to some, it actually provides an opportunity for building managers and community association boards to implement an effective long-term water conservation program. And the result can be significant dollar savings. ...

  • The Importance Pressure Management on Agricultural Irrigation Applications

    Irrigation systems world wide are dependent on sound pressure management techniques which are normally incorporated at the design phase of the project. This holds true whether you are designing agricultural irrigation systems incorporating drip, micro spray, sprinkler or pivot systems and has similar ramifications for turf irrigation or even golf course irrigation systems. Automatic ...

  • India's groundwater irrigation boom: can it be sustained?

    Development of groundwater irrigation (GWI) has been very impressive in India, especially after the introduction of the green revolution. The area under GWI accounts for 62% of the net irrigated area today. Though GWI provides added benefits to farmers, compared to other sources of irrigation, the continuous exploitation of groundwater of late has resulted in a drastic drop in the water table, ...

  • 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 ...

  • Leaching of three sulfonylurea herbicides during sprinkler irrigation

    Sulfonylurea herbicides are widely applied on the Canadian prairies to control weeds in a variety of crops. Several sulfonylurea herbicides are mobile in soil, and there is concern about their possible movement to ground water. This study was performed to assess the susceptibility of three sulfonylurea herbicides commonly used in prairie crop production to leach under a worst-case scenario. ...

  • 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. ...

  • Colorado Irrigation Canal Channels - Case Study

    Project Background “Different materials to protect canal liners had been tried in irrigation canals across the West over the past 15 or 20 years.   One typical method uses a low cost earthen material like clay. Over time, however, these systems begin to crack and start to leak.  It’s not a very efficient way to convey water,” notes Joe Kaul, Kaul ...

  • Transferring irrigation management to farmer's associations: Evidence from the Philippines

    Irrigation management transfer (IMT) is an important strategy among donors and governments that aims to strengthen farmer control over water and irrigation infrastructure. In this study, we use data from a survey of 68 irrigator associations (IAs) and 1020 farm households in the Philippines to examine the impact of IMT on irrigation association performance and on rice yields. We find that the ...

  • Behavior of atrazine in limited irrigation cropping systems in Colorado: prior use is important

    Received for publication October 28, 2008. Glyphosate-resistant (GR) corn may be a major component of new cropping systems to optimize the use of limited irrigation water supply while sustaining production. Because atrazine is an important tool for residual weed control in GR corn, we examined atrazine binding to soil, dissipation, movement, and early season weed control in limited and full ...
