• As a major agricultural exporter, Australia feeds not only its own
population but also some 50 million people in other countries.
These exports are vital to our economy and make an important
contribution to the world’s food supply.
• Farmers and scientists are working together to lift production and
improve product quality, and also to overcome major threats to
sustainability that have emerged over the years.
• As farmers we know we must look after our land so we can
continue to produce food to feed the people of Australia and
those in other countries.
• Dairy farms rely on natural resources like sunlight, soil and water
as well nutrients (food or chemicals) to grow the pastures to feed
the cows to produce milk.
So lets have a look at
sustainable dairy farming.

Sustainable Farming at Clover Hill
Our farm business is a partnership between our
cows and the landscape Our farm is in an

many native animal species.
Supporting this biodiversity
is important to us .
Some of the things we are doing include:
• Trees: Undertaken extensive tree plantings and
established shelterbelts to provide both protection and
shade for the cows and the indigenous animals.
• Troughs: Installed off stream gravity fed water troughs
in all paddocks which means we can fence off our
waterways. This has resulted in improved water
quality for our cows and the wider catchment and less
riparian erosion – and of course gravity fed water
means we can significantly reduce our stationery
We have troughs in
all our paddocks so
the cows don’t need
to enter the creeks to
• Laneways: Invested in well built laneways to provide for
cow comfort. This has the added benefit of improving
downstream and on farm water quality because faster
cow flow means more nutrients stay on the paddocks and
less is deposited in the laneways.
• Pasture: Optimising pasture cover is good for the cows and
milk production and its good for water quality as good
pasture cover means less nutrient runoff in high rainfall
• Soil Health and Fertiliser Use - We measure what goes in
and what goes out – this means we can reduce
unnecessary fertiliser use and reduce green house gas
emissions and costs.
So for our farm to be
sustainable it must be

More stuff about worms
• Earthworms are like free farm help. They help to
"turn" the soil—bringing down organic matter
from the top and mixing it with the soil below.
• Another interesting job that the worm has is that
of making fertilizer.
Pretty amazing for just a little old worm,
don't you think?
Good stuff on worms here:
Most soils contain four

Organic matter can be

living organisms. The

for an average soil.
And of course
plants live in soil.
So lets look at what
makes plants tick.
Lets start with the
Carbon dioxide + water + sunlight = sugar + oxygen
• Plants absorb a common gas called carbon
dioxide, pull water up through their roots and
use light to make sugar.
• Plants use the sugar to grow.
• Plants give off oxygen as a by-product.
• The green parts of the plant make the sugar
Holding the soil together
• A web of powerful roots deep underground
also helps hold the soil together and keeps its
nutrients exactly where they’re needed.
• Soils become well-conditioned and able to
grow better pasture.
• Stronger soils and better pastures are then
better-able to fight off attacks from weeds
and harmful insects.

Cows can eat 100kgs
grass per day which is

Fertiliser is very useful in this
Read all about fertiliser in our
Grow Grass Grow series
and remembering with fertiliser –
the aim of the game…
is to keep the nutrients on the pasture
and out of the airways and waterways.
So its very important to:
• measure what goes in and what goes out
• only apply what you need, where you
need it and not when rain is going to
So farmers wouldn’t
put fertilisers out in
especially as there is
no grass cover to hold
the nutrients and
prevent soil erosion.
What Goes in vs. What Goes Out
Nutrient budgeting is used by all good farmers.
• The process involves balancing nutrients coming
into the farming system with those leaving.
• The aim is to prevent pollution events and save
costs by precisely matching the nutrient
requirements of the crop with application of
organic and inorganic fertilizers.
Nutrient Management Plan
A nutrient management plan is a set of
conservation practices designed to use fertilizer and/or
manure effectively while protecting against the
potential adverse impacts of manure, erosion and
organic by-products on water quality.
To create the plan we:
• Soil test
• Manure test
• Practice erosion control
• Manage soil for pH
• Time fertilizer/manure application.

• We farm in that small pocket of Australia where traditional climate
variability is much greater than that predicted by climate change
• So for us climate change will certainly have positives. It is predicted that
there will be a slight increase in temperature with little impact on
average rainfall which means we can grow more pasture with less feed
gaps (we are usually short of pasture in March & April)
• Our key management strategy is to grow as much pasture as we can and
this allows us to have a high stocking rate. We currently run 4 to 5 cows/
• We are trialling water and nutrient efficient grasses. Pastures that use less
fertiliser and grow better on the moisture shoulders mean we can reduce
costs and emissions
• We grow drought tolerant pasture species with potential for rapid
recovery after drought
How does the weather affect
• Cows don’t like it too hot or too cold –between
15 and 25 degrees centigrade.
• Cows need shade and shelter to produce milk.
• The weather also affects how and when the
grass grows ( and of course it grows much faster
Australian cows are lucky they get to live
outside in the sunshine and fresh
air and eat grass

Now we are going to talk about
the importance of shelter for the
farm land and the animals.
• Planting trees and shrubs means many good
things for birds and native animals, for other
sorts of plants, for the soil and … oh yes, for
the cows, too.
• Planted in rows, trees offer shelter from wind,
rain and hot sun.
• These shelterbelts of trees and plants make
life more comfortable for the dairy cows …
and the people who work with them.
• Down below the ground, these shelterbelts
are doing more good work.
• Their powerful roots are pushing through the
soil to drag up water.
• This action means that the soils do not get too
soggy, or waterlogged.
• Nor do they get too full of salt – a problem
called soil salinity.
In 2007 we increased the length
of the shelterbelt and put in a big

• Winning this award has been the highlight of
our farming journey.
• It doesn’t mean we are perfect farmers- far
from it – what it means is we are adaptive
• We are committed to producing more milk
