Sustainable dairy

Class: 3 Long

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

the dairy.

• 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

irrigator on.

• 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

the atmosphere.

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

more transport.

Grain can be worse and can

be better

Grain is better for the

environment because

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





• We are trying to reduce our electricity bill.

• By reducing pumping costs, we can become more energy efficient on

the farm.

• 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)
