Men of the Trees in Western Australia
Men of the Trees in Western Australia
Field and nursery trials directed by Barrie Oldfield, President.
Interpreting Results:
- Five times the growth for the same species of trees.
- The potting out time has been shortened from five months to six weeks.
- The fineness of the dust particles is more important than the actual mass of the dust material.
- With dust of which 61.9% of has a particle size of 75 microns or less, the beneficial plateau in these trials is in the region of 15-20 tons/ha. At 12 tons/ha the plant growth was markedly inferior.
- Men of the Trees plant 1/3 million trees per year, mostly in arid climates in Australia and Africa.
- Material used: granite dust from Pioneer Quarry.
