  • Fertilization and blending alternatives for irrigation with desalinated water

    Received for publication April 29, 2008. In arid-zone agriculture where available irrigation water is saline, desalination is becoming an attractive method for increasing yields and reducing negative environmental consequences. However, irrigation with desalinated water can be problematic if essential nutrients, including Ca, Mg, and S, removed during reverse osmosis, are not reintroduced. We ...

  • Scalewatcher Banishes Limescale In Gardens And Greenhouses

    In hard water areas, automated watering systems, sprinkler irrigation systems and greenhouse-misting systems clog with limescale, plant leaves develop white scale deposits and over-spray causes limescale build-up on greenhouse windows. Scalewatcher North America, manufacturers of the original, patented and award-winning computerized electronic water-conditioner, Scalewatcher®, has a range of ...

  • 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 ...

  • Measurement and modelling of the water requirement of some greenhouse crops with artificial neural networks and genetic algorithm

    Crop evapotranspiration is the most important parameter for management of irrigation systems in greenhouses. This study was conducted to determine the evapotranspiration of cucumber, tomato and peppers, using micro–lysimeter during seven months in a greenhouse located in central region of Iran. Reference evapotranspiration estimated using drainage lysimeters and the water balance of soil ...

  • Performance evaluation of condensation–irrigation solar system under arid climate conditions

    Scarcity of water, major critical concern in arid areas, has led to the use of low–quality irrigation water in agriculture in most of arid climate areas. The quality of water used for agriculture has to be reduced to a sustainable level that is also adapted to the environment. This paper presents the performance of a pilot condensation irrigation (CI) solar system in Tunisia under arid climate ...

  • Irrigation of eucalyptus plantation using treated bleached kraft pulp mill effluent

    The use of treated pulp mill effluent on eucalyptus plantation appears to be an attractive option for plant nutrition and water supply. It also constitutes a supplementary treatment process and a final disposal option for the mill effluent. This study aimed at the investigation and evaluation of the effects of bleached kraft pulp mill treated effluent on three typical Brazilian soils used for ...

  • Wastewater retreatment and reuse system for agricultural irrigation in rural villages

    Climate changes and continuous population growth increase water demands that will not be met by traditional water resources, like surface and ground water. To handle increased water demand, treated municipal wastewater is offered to farmers for agricultural irrigation. This study aimed to enhance the effluent quality from worn-out sewage treatment facilities in rural villages, retreat effluent ...

  • The use of treated wastewater and fertigation in greenhouse pepper crop as affecting growth and fruit quality

    The performance and suitability of tertiary treated wastewater (TW) and/or fertigation (F) in pepper plants were studied over a 4-month period in greenhouse conditions. Four treatments were used consisting of (1) water, (2) water + F, (3) TW, and (4) TW + F. The F and/or TW application increased plant height and plant biomass compared with the control plants (irrigated with water) ...

  • Re-evaluating the rationale for irrigation technology adoption through an integrated trade-off analysis: case study of a cotton farming system in Australia

    While the prevailing rationale for new irrigation technology adoption is improved water use efficiency, this study evaluated trade-offs between water savings, greenhouse gas (GHG) emissions and economic gain associated with the conversion of a furrow irrigation system to a sprinkler irrigation (lateral-move) system on a cotton farm in eastern Australia. Trade-offs were evident when conversion to ...

  • 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 ...

  • Downward mobility of 14C-Labeled simazine in a bermudagrass system vs. a fallow soil system

    Pesticides applied to bermudagrass (Cynodon dactylon L.) can be captured by the canopy, absorbed by the roots, or bound in the thatch layer, which reduces the amount available to leach compared with a fallow soil system where pesticides may be applied directly to soil. 14C-Simazine was applied to dormant bermudagrass and fallow soil in lysimeters in a cold growth chamber (5°C) (cold-fallow soil) ...

  • Climate justice: creating urgency and safeguarding rights

    The United Nations climate change convention is 20 years old this month. As we see from the just-completed climate talks in Bonn, Germany, we still haven’t solved the problem, nor even agreed how to solve it. Meanwhile, the impacts of climate change become more apparent, hitting the poorest and most vulnerable the hardest. Within this statement lies a deep injustice: Those most affected by ...

  • Could food shortages bring down civilization?

    One of the toughest things for people to do is to anticipate sudden change. Typically we project the future by extrapolating from trends in the past. Much of the time this approach works well. But sometimes it fails spectacularly, and people are simply blindsided by events such as today’s economic crisis. For most of us, the idea that civilization itself could disintegrate probably seems ...
