  • “Efficient” irrigation tool may deplete more water

    An Israeli water engineer was sitting under a tree one day when he noticed a leaking faucet slowly drip water to the tree's roots, a nearly 50-year-old irrigation tale says. The idea inspired the invention of modern drip irrigation, also known as micro-irrigation. The method runs water through plastic tubes that release the flow through small holes directly to crop roots or stems. The precise ...

  • New irrigation strategies for pecans in humid climates

    Georgia is the largest pecan producing state in the U.S. Although this humid region receives an average of 127 cm or more rainfall annually, periods of moisture stress can occur during the pecan growing season, particularly during August and September when pecans are in the kernel-filling stage and water demand is at its peak. Pecan producers throughout the region depend on irrigation strategies ...

  • Crop Insurance Approved for Pivot-Irrigated Rice

    It has taken a lot of time and work (mostly by other people), but last week we finally got some good news in the pivot rice world. The USDA’s Risk Management Agency board of directors approved the application to provide crop insurance coverage for producers who want to grow rice with pivots. This means that by as early as next spring producers will be able to insure their pivot-irrigated ...


  • Solar-powered irrigation improves food security in West Africa

    Solar-powered irrigation that delivers water directly to plant roots could help ensure food security in Africa, say researchers. Their study in the Sudano-Sahel region of West Africa indicated that this irrigation method could increase both household income and nutritional intake, particularly during the dry season. The food supply in many parts of sub-Saharan Africa is considered insecure in ...

  • UF/IFAS avocado irrigation app should save money, water

    Avocado growers now know that a University of Florida Institute of Food and Agricultural Sciences mobile irrigation app works well to save money while maintaining crop yields. This data, reported in a new study, is critical for an industry that has a $100 million a year economic impact on Florida.
