TREE
RESEARCH February 14, 2002 The following are the results of the
study to determine the effect on growth by applying NUTRIPAK on three and four
year old loblolly pine trees. Three separate tracts in northeast Mississippi
were selected. Plots were established on each tract. Each plot consisted of treated
and untreated trees. Trees were measured in May, 2001 and remeasured in February
2002. The increase in growth of the untreated trees was considered to be the normal
annual growth. The increase of the untreated plots was subtracted from the increase
of the treated plots. The difference was considered the growth attributable to
the NUTRIPAK treatment.
