root growth/how they do that
drip line (feeding line/capillary transmission)
growing a tree evenly (above and below ground)
(NPK/compost may grow too much top too fast)
acid in roots dissolve minerals
trees then take them up into themselves
trees hold (and therefore) tie up water
in re: old growth (barrels)
how far do the roots grow from the tree?
what happens to the roots when the tree is cut down?
what do tree ROOTS do for the tree?
#1. convert minerals into a useable form for growth (breaking up rock)
#2. take up and hold water
#3. provide a stable place for the tree to grow
#4. keep it in place through wind, snow, rain, dry
#5. they may also create secretions that are amenable to their own (and non-competing) types of plants
(+/- catechins) allelopathy U of Colorado (spotted knapweed)
ROOT KNOT (CROWN in grass)
Conversion point where nutrients from photosynthesis meet nutrients from root conversion.
AIR: crenelated area in bark, trees that grow in water take in air there. circulation, breathing
EVERYTHING passes through this spot on the tree
pays to think of this as nostrils and mouth
we've all heard of trees being smothered by having this area buried too deeply
This is what you see (board) this is what is really there
why does the tree produce a log?
what is going on, from the tree's perspective, as that log grows?
stabilization of new growth
faster/greater uptake (and circulation) of water, minerals (building blocks)
there is also evidence that trees grow much taller/faster than usual when placed in competitive situations (not proof, just evidence)
-- release cutting...how it works
-- dangers of planting too close
-- disease transmission #1
-- shortage of water, nutrients, simple room to grow
How close to plant trees?
-- Forestry department has worked out the ten x ten system. NATIVE TREES!
-- most effective for HARVEST
-- good for quick growth as well NATIVE TREES
#1. Adds photosynthesis to general food system.
--what does the TOP of a tree do for the tree?
#1. the tree gets to spread its own seed farther by its own height
-- photosynthesis (sunlight into feed)
-- the top is where ALL new growth happens
-- all other growth: roots and trunk are side issues to stabilize that top
-- each tree that reaches its greatest potential height produces an estimated million seeds.
-- his is a "catch-as-catch-can" reproductive system (seeds separate subject)
BLM plants in style of chop/put tree in/stomp dirt around it
-- smaller trees/quicker starts
-- trees root into hard soil sooner
-- gets huge amounts of work done fast
-- roots do grow from there
-- fast procedure gets trees out of air exposure quickly (Air pruning)
what we are doing here is different
#1. tree is non-native, EXOTIC has to make the best it can of situation
#2. tree is older than normal seedling transplant (greater root/top development) needs greater consideration.
#3. by taking all dirt out and replacing it, dirt is loosened/compaction less
this encourages new root growth
#4. adding peat moss/no nutritive qualities whatsoever/water-holding superb/ slows water evaporation over summer
adding rim to hole makes summer watering possible (hole disappears over time)
sawdust around tree reduces or eliminates competing weeds/also helps slow evaporation
WHERE to plant
-- Land Plan first ("Planning changes everything" ---Steve Renquist)
-- Suggest retaining DIVERSIFICATION
-- plant 3 or 4 different species (insurance against market lows)
-- (100-year drought cycle beginning)
-- plant in strips, checkerboard, contours of land whatever
-- by planting in blocks or strips, you:
-- reduce potential spread of disease/parasites by INTERRUPTION
-- if a fire gets on your place, you have automatic fire-breaks
-- market variations mean you may have 1 type of log that will sell, when others will not
-- overall, even selling low, you will make out better in the long run.
-- more acres diversified, better such a plan will work
-- Start this type of program by making current and near-future harvests in smaller strips/blocks. Replant in diverse patterns. In the end, quicker results.
