  • Tree Ownership and Responsibility (C 1099)

    This publication discusses the ownership, responsibility, and liability of trees. It presents common situations in which a neighbor's trees encroach on another's property and suggests ways to resolve related conflicts. Published on Oct 31, 2016.

  • Pecan Water Requirements and Irrigation Scheduling (C 1106)

    Pecan trees have high water requirements, using as much as 60 inches of total water (including rainfall) during the growing season. Georgia receives an average of 50 inches or more of rainfall annually. While the rainfall received certainly meets a portion of the water requirement for pecan trees, periods of moisture stress occur during the growing season, particularly during the months of August and September when pecans are in the kernel filling stage and water demand is at its peak. Thus, irrigation has been proven to markedly enhance pecan production in the region.

    With increasing agricultural water use, a growing population, and declining groundwater levels, irrigation efficiency in the region is necessary for sustainability. Drip and micro-irrigation system design capacity for a mature pecan orchard should be 3600-4000 gallons of water per acre per day. Because of evaporation losses, solid-set sprinkler irrigation can require as much as 3 times more supplemental water than drip or micro-irrigation.

    Solid set irrigation systems should have a design capacity of 1.5–2 inches per week. Water stress in pecan is correlated with soil moisture from budbreak through the end of nut sizing. Pecan trees bearing a moderate to heavy crop load may undergo water stress during the kernel filling stage regardless of soil moisture level. This suggests that crop load and nut development drive the tree's demand for water. Published on Oct 31, 2016.

  • Hay Replacement Rations for Cows and Early Weaned Calves (TP 103)

    Over half of Georgia has been in a prolonged drought since the beginning of May 2016, essentially the entire forage growing season. The drought has hindered the ability of many cattle owners to grow and/or procure enough hay to make it through the winter. Therefore, there is a need to economically develop dietary strategies to maintain cattle through the winter.

    This publication describes the process of evaluating potential feeds, outlines potential hay-replacement rations, and details considerations for feeding management. Published on Feb 28, 2014.

  • Take-All Root Rot of Warm-Season Grasses (C 1102)

    Take-all root rot (TARR) has emerged as a destructive disease in central, south and coastal Georgia. TARR affects all warm-season turfgrasses in Georgia, but it is more common and severe in St. Augustinegrass (Stenotaphrum secundatum).

    This publication contains important information on the biology of the causal agent, detailed descriptions of the disease symptoms (aided by high-quality, detailed pictures), relevant up-to-date information on conditions favoring the disease, and cultural, genetic and chemical methods of control. This publication is intended for turfgrass professionals, consultants, county faculty, homeowners, and general public. Published on Oct 31, 2016.
