Fertilizers
for native forests & plantations
Industrial waste being used in Gellibrand plantations
I found myself
in a recently logged Midway pine plantation in the Gellibrand River
Proclaimed Water Catchment (50,000 people's drinking water in the
States southwest) last week.
I noticed a
heap of discarded fertiliser slips at a log landing. These slips
gave the ingredients of a 25 kg bag of Hi-Fert Pty Ltd fertiliser.
(Hi-Fert are a subsidiary of WMC - Western Mining - owners of Roxby
Downs).
The usual ingredients
included nitrogen, phosphorus, sulphur, calcium were listed on the
slips. But this batch also included; 8mg/kg of Cadmium, 1.6mg/kg
of Mercury, 24mg/kg Lead with small traces of Aluminium and Fluorine
(a by-product of the Aluminium industry- which WMC are also involved
with). In less than one minute I found 8 of these labels lieing
around.
This means that
each bag of fertiliser used on this pine plantation contained: 200mg
of Cadmium, 40mg of Mercury and 600mg of Lead.
I found 8 of
these labels meaning that at least 8 bags of this stuff were used
- the actual figure would be much higher. So just on what I found:
at least 1600mg of Cadmium, 320 mg of Mercury and 4800mg of Lead
were recently dumped onto this pine plantation near the headwaters
of Barramunga Creek in a domestic water catchment that supplies
over 50,000 with drinking water.
If I was a very
dodgy mining company and I wanted to offload heaps of industrial
waste, would I dump of all this waste in one location incurring
the wrath of people living in that area, or would I spread the waste
all over many farms and plantations throughout Australia under the
disguise of a nice safe and clean fertiliser company? Furthermore
if I was a dodgy mining company and I know of an equally dodgy woodchipping
company could I persuade that woodchipping company to dispose of
large quantities of my industrial waste for me in their pine plantations
by upping the industrial waste content of my fertilisers?
Why do trees
need Lead and Mercury and Cadmium to grow? Do the trees absorb these
heavy metals? What happens to the heavy metals when the tree is
cut down?

Rumours
that DNRE want to start using fertilisers in native forests
It's rumoured that DNRE want to start using fertilisers in native
forests.
Their regeneration is not fairing too well so they need a 'growth-booster'.
Plantation companies use fertilisers already. For instance Amcor
used
1.5 million tonnes of the stuff a few years back. Unsure how much
Hancock now use. Hancock
buy their fertiliser from a sales, marketing and distribution
company called Hi-Fert.
Hi-Fert is a subsidiary of WMC Pty Ltd (that's right - the uranium
miners). Hi-Fert mainly sells ammonium phosphate fertilisers. Ammonium
phosphate fertilisers are sourced from 3 processes and mixed
together:
(a) Sulphuric
acid sourced from metalurgical sulphur dioxide emissions at MIM
mines in Mount Isa and Sun Metals (a Korean owned Zinc refinery)
based in Townsville.
(b) Ammonia from natural gas supplied through the Carpentaria pipeline
(c) Phosphate rock from WMC's operation at Phosphate Hill in Qld.
Ammonium phosphate is also produced at WMC's Nickel refinery in
WA.
Nothing like a nice dose of industrial waste in your water catchments!
