  • Procedure for rapid determination of δ15N and δ18O values of nitrate: development and application to an irrigated rice paddy watershed

    The dual isotope approach using the stable isotope ratios of nitrate nitrogen (δ15NNO3) and oxygen (δ18ONO3) is a strong tool for identifying the history of nitrate in various environments. Basically, a rapid procedure for determining δ15NNO3 and δ18ONO3 values is required to analyze many more samples quickly and thus save ...

  • Comparative advantage for the areas irrigated with underground blue water in North China Plain

    North China Plain is one of the most important grain-producing areas in China. Because of unevenly distributed precipitation in this semi-arid area, crop production largely relies on underground blue water (UBW) to irrigate, overexploitation of which causes a lot of environmental problems. In this paper, we first defined the representative division of winter wheat irrigation water production ...

  • Virtual water and phosphorus gains through rice imports to Ghana: implications for food security policy

    This study estimated the gains of virtual water, Phosphorus (P) and Phytic Acid (PA) through rice and wheat import to Ghana for the period 1998–2005, and assessed the implications of increasing rice import coupled with declining domestic production for food security. The total virtual water of Ghana associated with rice and wheat import for the study period was 5574 Mm³, while the total P and PA ...

  • 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 ...

  • Assessing potential of water rights and energy pricing in making groundwater use for irrigation sustainable in India

    Groundwater emerged as a major source of irrigation in India during the mid-1970s. However, a large expansion in well irrigation due to a massive rural electrification programme, government policies of promoting private tube well construction and large subsidies on electricity for agricultural use resulted in groundwater over-abstraction in many semi-arid and arid regions of India. In addition, ...

  • Large-scale irrigation - Understanding energy-water-food connections

    Original story at MIT News An MIT team is providing new understanding of the growing interconnections among three critical resources: energy, water and food. The work focuses on Pakistan's Indus Basin, where irrigation water is increasingly pumped from underground, a practice that is intensifying a preexisting shortage of energy. Using new and ...

  • Grain Yields Starting to Plateau

    By Lester R. Brown From the beginning of agriculture until the mid-twentieth century, growth in the world grain harvest came almost entirely from expanding the cultivated area. Rises in land productivity were too slow to be visible within a single generation. It is only within the last 60 years or so that rising yields have replaced area expansion as the principal source of growth in world grain ...

  • Macro–engineering Australia's Lake Eyre with imported seawater

    The macro–engineering project proposal exploits technologies that have the potential to quickly enliven the arid region surrounding Lake Eyre. The plan is focused on biosaline agriculture. The distinctive macro–project components are: Lake Eyre is gradually filled to a higher level by controlling evaporation and by pumping seawater from the nearby ocean using cheap tensioned textile tubes. Most ...

  • Ancient water robotics and Abou-l Iz Al-Jazari

    Although water resources have been developed throughout the centuries for the service of different civilizations, at different scales and in different regions, their use in automation has been conceived only recently. Research into the history of water from an automation point of view has led to some unknown or hidden facts. Starting from the ancient Greek period before the prophet Christ and ...

  • Egypt: The role of water users` associations in reforming irrigation

    Egypt’s water resources are severely constrained. This calls for increasing the water use efficiency by improving irrigation management practice, as the agriculture sector is the main user of water resources. Much of the irrigation infrastructure is elderly and in need of rehabilitation. The ...

  • Variable Demand Irrigation

    2,000 GPM Turbine pump supplies four 500 GPM pivot sprinklers After three VFD’s failed in less than five years, this farmer decided to try a Cycle Stop Valve. Three years later there have been no problems with the CSV. The system is able to supply one pivot just as easily as all four pivots when ...

  • Pump Stations: CSV vs VFD case study

    None of the problems associated with VFD exist when using a Cycle Stop Valve for control. With a CSV, the motor is always spinning at full RPM, but the amps are reduced similarly to varying the speed. When the motor is spinning at full speed, the cooling fan always provides adequate cooling. Spinning at full speed also means there are no problems with resonance frequency vibrations. Running on ...

  • Kentucky - Golf Homes Development case study

    Site: County Club Golf Homes Location: Elizabethtown Kentucky The Country Club Golf Homes (CCGH) located in Elizabethtown, Kentucky is a shining example of how technology, engineering, and land development can come together to make unsuitable land suitable for onsite wastewater dispersal. In late 2001, the CCGH developers required ...

  • South Carolina - truck stop case study

    The Kangaroo/Pantry truck stop is located at a busy intersection in Round 0. South Carolina where three state roads meet. Because of it's rural setting, it is a great place for truck drivers to fuel up their trucks and themselves anytime around the clock. The fried chicken cooked here is well known for miles around. So when the wastewater system failed and threatened to shut down this rural oasis ...

  • Re-coupling the carbon and water cycles by Natural Sequence Farming

    The techniques of Natural Sequence Farming (NSF) were developed during hands-on management of degraded farmland in the Upper Hunter Valley region of Australia. Early settlement of the continent by people with European cultural assumptions disrupted established interactions of water, soil, and plants resulting in lost fertility. Moreover, agricultural practices such as clearing, burning, ...
