I live on a farm at Meander.
We have 850 milking
• The shapes are to show where the main spots
are in the picture.
How well are we doing?
• We are doing well.
• One flight to Europe produces a bit over the
amount of carbon dioxide that our farm
produces in a year.
• We have trees planted all around our farm.
• Trees convert CO 2 (carbon dioxide) to O 2 (oxygen).
We are doing our best to make
our farm sustainable.
• What does sustainable mean?
• It means being careful with the resources on
the Earth so that they will still be there for
people in the future.
• It means that the Earth and its resources are
looked after and not wasted.
• It means doing things on our farm that allow
us to make enough money to survive and
keep doing things well.
We built our dairy in 2007.
The cows are being milked in
• We recycle effluent from our dairy.
• Our dairy uses lots of water to wash poo and wee away.
• First the waste water goes through the solids trench to
collect the solid poo. We clean it out and spread it on the
paddocks instead of using nitrogen fertiliser.
The water runs into the effluent pond and it still has lots of
nutrients in it.
I am turning the centrepivot
• We use it to water and fertilise our paddocks. We
don’t need to use other fertiliser on these paddocks
Other ways we are sustainable
We try to buy local grain to
feed our cattle because it
needs less transportation.
We grow ryegrass and we don’t
over do our soil with fertiliser if
we did, it would be worse for the
environment. If we did, the excess
fertilizer would run off into the
water and evaporate and go into
We use our own hay and silage
You would usually use hay in
winter and spring when the cows
aren’t milking .
This means we don’t have to buy
hay from other places which
saves pollution from more
You can store it for about 1 year.
You would usually use silage in
summer and autumn.
This also means we don’t have
to buy silage from other places
which saves pollution from
Grain can be worse and can
Grain is better for the
the cows burp less
methane but by the
time it gets transported
to you it is usually worse
for the environment
because of the pollution
caused by the
CARBON CYCLE OF A FARM
• We are trying to reduce our electricity bill.
• By reducing pumping costs, we can become more energy efficient on
• Our farm energy report showed we were pumping water from our bores
during the day and it was costing a lot. This is called peak power
because most people use power during the day.
• An electrician installed an automatic timing system so that we could
pump water at night. This is called off-peak power because less power
is used at night. It costs less too.
• Thank you Mrs Saville, Mrs Long and my
parents (Brian and Michele)
