As I draw a close on the last assignment in my ‘Sustainable Agriculture’ course, I have decided to share a succinct breakdown of the difference between four common growing methods used in Australia. These growing methods may be used on products that turn up in Beer, Wine, Spirits and other food and beverage products, not only in Australia but internationally.
Today’s alternative farming techniques include, but are not restricted to, four main preferred methods, each has it’s own set of rules, difficulties and environmental benefits.
The removal of soil in plant growth, confusing, yet effective, for those who practice the Hydroponic growing technique experience a challenging process with a string of pros and cons. ‘Hydroponics’ employs a soil-less root environment by exploiting a few scientific findings about root growth. Plant roots absorb minerals through dissolved nutrients in water particles, when in soil. Science has removed the need for the soil medium and provides through, irrigation, misting or submersion, the roots being exposed directly to the mineral solution.
In some cases removing some type of fertilisers and other treatments, minimising water use and utilising growing space more effectively.
Further down the spectrum, Permaculture [Permanent Agriculture], which is not necessarily a technique of farming, but a way of living as you farm, includes the utilisation of existing opportunities presented to a farmer. ‘Permaculture’ is true sustainability in a harmonious regenerative sense; both farmer and environment require minimal energy. Permaculture focuses on the implementation of planned farming by way of traditional permacultural planning; Yeoman’s Keyline system, Feng shui or even geomancy for some people or cultures.
Focusing on ethical farming, planning and cultivation, permaculture is a truly sustainable way of farming on a small scale and great for personal use and focuses also on the techniques of storage or usage after harvest, as well.
Not too dissimilar, but productive on a larger scale, Biodynamic farming, originally conceived by Rudolf Steiner, is a conscious style farming. Considering the landscape to be a living organism, biodynamics takes into account the relationship of animals with plant and soil production effectively utilising by-product to regenerate back into the biodynamic ecosystem on a cyclical basis. Also eradicating chemicals and minimising energy consumption, biodynamics focuses on a natural method of farming and cultivation, which, in most cases, pays tribute to the lunar cycle and weather patterns for harvest.
Including all ethical responsibilities and employing strict sustainable processes, certified organics, is the ultimate farming technique to provide ongoing success of conscious farming. Tough but fair farming regulations require ‘certified organic’ farmers to eradicate chemical use from their entire targeted yield, whether it be stock, seed, vegetable or any other farmed crop the process will be regulated over a period of 1 to 3 years. Certified organics can employ biodynamic methods and principles of permaculture to help with the loss of chemical enhancement. Crop rotation, sustainable use of chickens and stock to help with fertilisation and parasite management, and also ethical water usage, all need be considered in this organic process.
Typically responsible, sustainable farming aims to reduce inorganic substance use and maximise the use of natural resource in the immediate surroundings.
