Should Fall Irrigation be Applied at Nurseries Located on Sands?
In 1985, fall irrigation on an Alpin sand reduced seedling stress and increased production of plantable loblolly pine (Pinus taeda L.) seedlings by 6% (40,000/ac). Applying about 0.5 in. of water/week (for 10 weeks) increased average height by 1 cm, average diameter by 0.4 mm, and average dry weight by 20%. At a cost of $17/ac, the additional irrigations increased crop value by $l,000/ac. Although ceasing fall irrigation has been recommended for nurseries located on sands, biological and economic data are needed to demonstrate that gains from stressing seedlings will offset the potential decrease in production of plantable seedlings.
