Effect of methyl bromide alternatives on seedling quality, nematodes and soilborne fungi at the Blenheim and Trenton nurseries in South Carolina: 2008 to 2009
Fumigation with methyl bromide (MBr) has been the most commonly used method for producing high quality, pest-free forest tree seedlings in the southeastern United States. Of the 1 billion seedlings produced annually, approximately 95% of seedlings grown for reforestation purposes are loblolly pine. Growth and survival of seedlings after outplanting is strongly linked to high quality, pest-free forest-tree seedlings...

Simulation of water uptake and redistribution in growing media during ebb-and-flow irrigation
To optimize ebb-and-flow irrigation on concrete floors, the relative importance of substrate type, flooding depth and flooding time on water uptake of growing media in containers is important information for the grower. Describing water uptake and distribution in the container with a dynamic simulation model may overcome the disadvantages of the static parameters such as container capacity and air capacity. Water uptake...
