  • Evaluation and Comparison of Slow-Release Nitrogen (N) Sources on Tifway Bermudagrass (2009)

    Research Topic:

    Evaluation and Comparison of Slow-Release Nitrogen (N) Sources on Tifway Bermudagrass (2009), Sartain, J.B., University of Florida

    Abstract:

    Slow release nitrogen (SRN/WIN) fertilizers provide controlled nitrogen (N) release over a longer time period, increased N uptake efficiency, and the potential to limit nitrate (NO3-) leaching losses. Turfgrasses respond differently to N sources depending on the N release rate and their ability to sustain plant available N over time. A field study was… Read More +

  • Field Evaluation of Different Fertilizer Formulations Including Various Combinations, and Nitrogen Sources and Rates on Recovery of Tifeagle Bermudagrass from Core Cultivation (2008)

    Field Evaluation of Different Fertilizer Formulations Including Various Combinations, and Nitrogen Sources and Rates on Recovery of Tifeagle Bermudagrass from Core Cultivation (2008)

    Research Topic:

    Tifeagle is a relatively new ultradwarf bermudagrass that is becoming the turfgrass of choice on putting greens of high-end golf courses in Florida. This turfgrass requires intensive management practices to limit thatch accumulation and maintain superior turfgrass quality and putting conditions. Core cultivation is one of the mechanical means used to remove… Read More +

  • Over-Seeded Rough Bluegrass (Poa trivialis) Response to Selected N Sources (2007)

    Over-Seeded Rough Bluegrass(Poa trivialis) Response to Selected N Sources (2007), J. Sartain, Universityof Florida

    Research Topic:

    Objective:Cool-season turfgrasses respond differentially to N sources depending on their release characteristics, soil texture, and organic matter composition.A field study was established on dormant tifdwarf bermudagrass over-seeded with rough bluegrass with the objective to evaluate the visual quality, growth and N uptake response of different N sources including a new technology meal and soy protein, soluble, traditional and synthetic slow release, traditional… Read More +

  • Tifeagle Bermudagrass Response to Selected N Sources (2007)

    Research Topic:

    Tifeagle Bermudagrass Response to Selected N Sources (2007), J. Sartain, Universityof Florida

    Objective: Tifeagleis a relatively new ultradwarf bermudagrass that is becoming the turfgrass of choice on putting greens of high-end golf courses in Florida.This new turfgrass requires intensive management practices to limit thatch accumulation and maintain superior turfgrass quality and putting conditions.A nitrogen source capable of limiting growth and consequently thatch development while maintaining high quality would ease the management difficulties of this… Read More +
