Introduction
Australia is oldest continent on earth and has one of the most fragile and least fertile soils. Other than Antarctica, Australia is the driest continent on this planet, with over 80% of our land arid and infertile. It has one of the least understood ecological systems in the developed world and there are new species of plants and animals discovered every year in Australia.
Yet for over 150 years we have been using “European Style” farming techniques with little regard to the fact that European soils are far more fertile and are often silt based, providing fertile soils every year.
Since the Second World War, the state of agricultural decay has increased dramatically with the “Great Agricultural Push in Australia”, in areas that were simply not suited for long-term agricultural use. Mechanisation, fertilisers, pesticides, herbicides as well as push to standardise products in order to increase yields (productivity) has led to extensive environmental catastrophes.
One example that clearly comes to mind is the vast lands in SW Australia (East of Perth), where people were fooled to believe that they could run agricultural operations over a long period of time.
Our land is still being deforested at a rapid rate leading to high levels of salinity, over-grazed leading to desertification and land degradation through bad soil management techniques.
Its water courses altered, dammed drained straightened etc. Whilst 95% of Victorian rivers lie in some state of decay, with fish breeding grounds lost, flows reduced, swamps drained etc. Our water management practices have in the past been inadequate. Just take a look at our open channel irrigation systems, which stretch across a vast reach of Australia. It loses a third of its volume through evaporation.
In 1983 during our last water restrictions the government promised that once the Thompson and Dartmouth Dams were finished that we would never have water restrictions again. Twenty years later it’s happening again. What has happened to our vision?
These are just simple examples of where our ignorance and lack of foresight has let us astray. There has been and still is an irresponsible approach to water, soil and forestry management.
Today Australia faces many environmental issues of which the most important are:
1.Water management
2.Land Degradation and poor soil management
3.Deforestation
4.Overgrazing
Yet very little has been addressed. For over 100 years we couldn’t even get Victoria South Australia and NSW to sign an agreement for a management plan for the Murray River.
These mistakes have led us to a more contemporary approach to agriculture. No longer are farmers just simply doing what “their fathers did”. It simply doesn’t work and is a time bomb ready to explode. The explosion being total desertification and degradation of our land within our lifetime! This has pushed us to a “big picture” approach to Agriculture, which has made us stop for a moment and think about what we are doing. Over the last 30 years there has been a push into sustainable agricultural practices leading us to better resource management with a long-term view.
Sustainable Agriculture can be described as resource management based agricultural system that minimises the impact of agriculture produce and practices whilst providing a profitable output or produce at minimal impact to the surrounding environment, both short and long-term, whilst maximising biodiversity.

Biodiversity
So what is so important about biodiversity? Biodiversity gives us the “quality of life” that enables us to survive and enjoy life. Life’s wonderful choices! Many choices provide many solutions especially in the random changing realm of Darwin’s Natural Selection. We must maintain biodiversity if the human species is to survive.

Farm Management Plan
An integral part of any Sustainable Agricultural venture is to have a Farm Management Plan.
This analyses all the resource to minimise inputs, and provides a suitable output with view to long-term sustainability.
Inputs
These inputs could be but are not limited to the following:
•Water
•Soil
•Fertilisers
•Seeds
•Chemicals including pesticides, herbicides, fungicides
•Labour
•Machinery including fuel

The Farm Management Plan should also incorporate a vision for what you want to achieve, assess the inherent risks and provide contingency plans to minimise all the exposure to risks as part of the plan. It also provide solutions through an Integrated Pest Management (IPM) Plan
A Farm Management Plan should look at all aspects of the current state of the venture and provide any solutions, generally organic based, to rectify any inherent problems occurring or to provide practices that will not lead to long-term problems.
Many of the problems in intensive (monoculture) agriculture can be reversed if all the parameters are understood. The problem in the past has been we have not taken the time to analyse and understand our soils and ecological systems that support us until it is too late. In the past, (and still happening today) there has been a push by big corporations, such as Monsanto, DuPont etc. to buy…buy….buy their agricultural products, whilst their consultants, provided us with the wrong, often biased information leading us to make bad choices over time.
Whilst Sustainable Agriculture is the right step in our approach to resource management we still have a long way to go to change people’s habits and provide them with a greater understanding of our ecological systems which is blocked by our ignorance and apathy from distractions such as terrorism, boat people and war on Iraq. The real issue is resource management, which we alone must take control of and not rely on external states or systems to determine our destiny or freedom of choice.

LV — Lubrication Oil Purifier Application LV series oil
purifier are suitable especially for purifying and restoring
hydraulic oil, machine oil, coolant oil and various other
lubrication oil. The most breakdown of machinery which has
lubrication oil system results from contaminated lubrication in
which has water, gas, impurities etc. LV series can rapidly
remove water, gas, particulate matters and impurities from
lubrication oil and improve properties of lubricating oil so as
to greatly extend lifetime of machinery which has lubrication
system.

Climate change is an amazingly simple phrase for such a complex subject. Following, we have a go at defining climate change in today’s terms.

Climate Change – What is it?

In the current day lexicon of scientists, climate modification isn’t really a term of use anymore. The reason for this is that we have come to understand that the effect of the changes we make to our environment will increase the temperature in many locations on the planet, but will also cool a few places. In light of this, the thing you know of as climate modification is actually referred to as global climate change. Over all, however, the world is definitely warming.

We need a simple definition for climate change in relation to the warming of the planet, one that gets the gist without excluding the simplicities. The simplest and most accurate definition is that climate change is the effect greenhouse gases have on the earth’s climate. Greenhouse gases include, but are not limited to, carbon dioxide and methane. While this sounds like a simple definition, there are a couple of key things to realize.

First, climate change is both a natural phenomena and one created by man. Put another way, greenhouse gases are a natural part of the biosphere and would exist if man did not. Indeed, they are a critical component to the existence of life on this planet. If greenhouse gases didn’t exist, the temperature on planet earth would average zero degrees! Naturally occurring gases, however, keep the temperature at a much more livable 59 degrees.

So, if climate change occurs naturally, what is the big panic about? The problem we are facing is the volume of greenhouse gases in the atmosphere. These gases act as thermal blankets for the atmosphere. The more gas in the atmosphere, the thicker the blanket and the less heat escapes. Over the last 80 years, we have been pumping massive amounts of greenhouse gases into the sky. At the same time, we have been reducing forestation around the planet, the primary plant collection that sucks greenhouse gases out of the atmosphere. This double whammy is starting to show negative results, the increased heating of our world.

The ultimate question with climate alteration is what will happen as the planet heats up. We are already seeing signs with the retreat of the glaciers. Glacier National Park, for instance, is going to have to be renamed since it has already lost 65 percent of all of its glaciers! While the exact end result of these environmental changes is not clear, we can expect major climatic changes over the next 80 years.

Native trees tolerant of wet soils are special group of trees.
These trees are able to be in soils that retain water for
sometimes weeks on end. I have compiled this list to help you
find suitable trees for the north east. This is not a complete
list but one of common EZ to plant nursery stock, but these
plants should do well in most of the Franconia Township Pa.
area. Our main farm is in Doylestown Pa. so if you need these
plants we are not far away.

Red and silver maple (Acer rubrum, A. saccarinum)

River Birch Trees a tree for wet areas!!!! (Betula nigra)
Catalpa spp.

Ash (Fraxinus spp.) Cottonwood (Populus deltoides) Swamp white
oak (Quercus bicolor) Sycamores (Platanus spp.)

Native shrubs tolerant of wet soils: Red osier dogwood (Cornus
sericea) Leatherwood (Dirca palustris) Winterberry (Ilex
verticillata) Sparkleberry holly A great berry producer!!!

Inkberry (Ilex glabra) Pussy willow (Salix discolor)

Willow Trees Trees for wet areas!!!!

Shrubby cinquefoil (Potentilla fruticosa)

Spicebush my long time favorite!!

Black Chokeberry produces great berry crops for the birds!!

If you love hummingbirds, keep your garden, yard, and
property clear of weeds. Especially burdock. The prickly
seedheads of common burdock can trap and kill hummingbirds.

During September, 1998, three hummingbirds were caught and
died in Rock Creek Park in Washington, D.C. A fourth
hummingbird was rescued by bird watchers.

According to National Park Service biologists, the burrs act
like Velcro. The barbed points on the burrs cling
steadfastly to fur, clothing, skin, feathers–almost
anything that comes near.

As the tiny birds thrash around trying to free themselves
they become even more entrapped.

While not much has been written about the subject, a
consulting ornithologist in Burnaby British Columbia reports
that the weed does occasionally claim the lives of small
birds and even brown bats.

Burdock, also known as Cockle Burr, is a biennial plant
which can grow to nine feet in height. Other names include
Fox’s Clote, Thorny Burr, Beggar’s Buttons, Cockle Buttons,
Love Leaves, Burr Seed, Clothburr, Turkey Burrseed and many
others.

Burdock was imported from Europe and is now widely
distributed in waste areas, abandoned farms, or any
uncultivated area in North America. It can also appear in
gardens and lawns.

The plant produces a rosette of large leaves, produces 15 to
40 or more pink or lavender flowers, and has a taproot of up
to 40 inches in length.

The plant must be eliminated before the flowers ripen and
form the brown prickly burrs which spread the seeds.
Selective or spot herbicide treatment isn’t always effective
because of it’s deep taproot. Pulling up or digging the
plant is the most effective but the entire taproot must be
removed. The sooner this is done the easier it is to do.
Smaller plants can be dug up using a standard garden fork or
dandelion digger, and larger ones using a long-handled bulb
planter.
