Our pine plantation is off and running 18 months after
planting. I figured its time to share with you an
update on a different kind of farming; tree farming. To
appreciate this, you will need to
read the blog of January 22, 2007
and see the photos taken at that time. I think you
will be amazed the difference 18 months has made
when you compare the pictures.
The method we chose for our plantation was very
different than normal practices. We planted about half
the number of trees per acre as the Texas Forest
Service and consultants recommend, did our site prep
chemical release six months before planting instead of
a year after and used containerized trees, not bare
root seedlings. Our march to the beat of a different
drummer continues.
Since January 2007, we have not had a drought and have
had normal rainfall and temperatures. The trees when
planted were no more than 8-10 inches tall on average.
Eighteen months later they are 18 to 38 inches tall on
average. Some approach four feet. The two pictures
below are of a taller tree and one that is average.
From a walking survey, it would appear that we have
very few seedling losses. In a bare root planting,
often you lose 25%. Based on the results thus far, we
seem to be on the right track with this planting
method.
Our objective in using these methods was to avoid
having a small wood (pulpwood) cutting, which is low
value in 14 years, but have a higher value chip and saw
cutting at 10 to 12 years.
We have a mowed fire lane around each of the new
planting areas and will continue to maintain it. Our
future plan is to fertilize the seedlings by over
planting with some type of legume that fixes nitrogen.
We have not figured what to plant nor how to do that
since we can not plow or disk the planted areas. Aerial
dropped fertilizer is too expensive in today’s
market. Once the trees reach a height of ten feet or
more, we hope to have fenced each of the areas planted
with woven wire sheep and goat fence. We will utilize
goats and sheep to clear out the understory of
uneconomic growth. In theory, if we open up the area
under the pines, grasses will grow keeping the ground
cooler and help retain moisture helping the trees to
grow even faster. The understory competes for water and
nutrients much more than grasses. Once the area under
the trees is open, we have a lot more options on
fertilization. Also, an open planted pine forest is
attractive to wildlife and has more recreational uses.
Terms of Reference:
CHIP-n-SAW - A cutting method used in
cutting lumber from trees that measure between 6 and 14
inches diameter at breast height. The process chips off
the rounded outer layer of a log before sawing the
remaining cant or rectangular inside section into
lumber. Chip-n-saw mills provide a market for trees
larger than pulpwood and smaller than saw timber.
Pulpwood - Wood primarily for
manufacture into pulp for use in making products such
as paper and textiles. Typically pulpwood is too small
or too low in quality to be used for lumber or plywood.
Chemical Release - The principal goal
of applying herbicides in pine plantations is to
enhance crop tree survival and growth rates in an
economically feasible way. This goal is realized by
suppressing or, less frequently, eliminating competing
vegetation, hence increasing water, sunlight, and
nutrient availability to crop trees. Reducing
competition for site resources is especially critical
for young pine seedlings. Therefore, herbicide
applications are usually most effective early in the
rotation, before tree planting or during the first two
years after planting, when seedlings are becoming
established. Effective site preparation and herbaceous
weed control reduce pine mortality and provide for
early and long-lasting tree growth increases. Good site
preparation reduces the need for herbaceous weed
control.
Understory - The understory consists
of hardwood trees, saplings, small ground plants, and
vines that emerged after the land was prepared for the
pine plantation.
