ha) was minimal, while controlling water table levels at 46 and
92 cm resulted in relatively large growth increases over that
obtained on a fluctuating water table.
 Response to fertilizer increased with decreasing water table
depth. The best growth of both species was made where the
water table was controlled at 46 cm. Furthermore, better growth
was obtained on both the 46- and 92-cm water tables than on the
fluctuating water table.
 Slash pine made better growth and yield than loblolly pine
on all water table conditions on this site.
 Fertilization and water table significantly influenced the up-
take and distribution of elements. These reflected both biomass
changes and the larger soil volumes exploited by the more ex-
tensive root systems.
