  • Agroforestry and grass buffer effects on water quality on grazed pasture watersheds 

    Udawatta, Ranjith P.; Garrett, Harold E.; Kallenbach, Robert L. (2009)
    Conservation practices including agroforestry and grass buffers are believed to reduce non point source pollution (NPSP) from grazed pasture watersheds. Agroforestry, a land management practice that intersperses agricultural ...
  • Agroforestry interactions and soil water use in watersheds under corn-soybean management 

    Udawatta, Ranjith P.; Anderson, Stephen H.; Motavalli, Peter P.; Garrett, Harold E. (2009)
    Agroforestry and grass buffer practices reduce non point source pollution from corn-soybean watersheds, yet little is known about the processes and mechanisms involved. The objective of this study was to compare the soil ...
  • Microclimate modification by tree windbreaks in Florida farms 

    Tamang, Bijay; Rockwood, Donald L.; Andreu, Michael G. (2009)
    Florida citrus and vegetable crops generate billions in revenue every year. However, winds, freezes, hurricanes, and citrus canker (Xanthomonas campestris) impact production. Windbreaks located perpendicular to the prevailing ...
  • Thirty million agroforesters : Russia's family gardens 

    Sharashkin, Leonid; Gold, Michael (2009)
    Today, over 30 million Russian households engage in food gardening and collectively produce over half of Russia's agricultural output, using less than 6 [percent] of agricultural land in the country. The small size of plots ...
