Organics can help make any farm or garden more sustainable both in the short and long term. It can reduce both establishment and maintenance costs, if practiced properly.

  1. Organics is a low input way of growing plants. You do not need to invest so much money inexpensive chemicals and fertilisers. Any declines in initial production are balanced against these reduced costs.
  2. Organics is less likely to result in land degradation than many other production methods;  hence the long term cost of sustaining production is less.
  3. If growing produce to sell; organic produce can command a premium price and may have other marketing advantages.

To be recognised as being an organic producer you need to abide by guidelines that are set by various bodies in your country.

One problem with marketing organic produce, particularly fruit and vegetables, is that people may think that slightly blemished looking produce is a poorer quality. Well grown organic produce however doesn't need to be marked, and in many cases can have a better flavour.

Consumers will often pay a higher price for organic produce, than non-organic produce. Consequently profits can be improved. However, it should be noted that without good cultural knowledge of the crops/animals a farmer is producing, serious losses can occur.

Organic farming is not a 'lazy farmers' technique. A lot of work is involved in utilising integrated pest management and hygiene above and beyond most normal farm enterprises. Once an organic production management system is in place, however, and operating, it tends to stabilise over a period of time, and becomes easier to manage.   

Important principles for organic growing, according to industry leaders, include:


  • To promoting established biological cycles on a property; encouraging the micro-organisms in the soil, plants and animals already living in that microclimate.

  • To maintain environmental resources in a local area, using them with care and sustainably. Any use of resources should be very efficient and materials should be recycled as much as possible.

  • To reduce reliance on external resources as much as possible.

  • To minimise contamination on site

  • To not export pollutants off site
  • To maintain genetic diversity on site and beyond.

Typical organic practices include using natural fertilisers, composting, inter-cropping, rotating crops and non chemical weed and pest control.


No course will guarantee you a job - but choosing the right one will certainly help!

Not all courses are equal some tend to focus on just getting you to the end, rather than helping you to learn.

The fundamental aim of a 'good education' depends very much on three processes:

  1. Gathering knowledge - what you learn.
  2. Retaining knowledge - how you learn and store it.
  3. Recalling knowledge – recollecting what you have learned, even years later.

Choosing what you learn: Education should be broad as this develops your knowledge and skills. When choosing an industry such as horticulture it is always best to learn the basic fundamentals first i.e. the core skills needed to work in the industry in general, that way you can move across inter-industry sectors if needed. The core units for a Certificate in Horticulture (for example) will give you good basic industry skills that can equally apply to nursery work, crop growing, gardening or other inter-industry sectors. Once you have these skills, your future prospects for employment are far brighter as you are a value to the industry in general, rather than to just a single industry sector e.g. crop growing.

Retaining knowledge: There are keys to retaining knowledge – most of us will only store knowledge in short term memory the ‘if you don’t use it you will lose it scenario’. As educators we have found at ACS that the best system for storing knowledge is to really know your subject. This may sound obvious but many courses just teach the facts. When students are set problems to solve and practical set tasks, like we do at ACS, rather than just reading and regurgitating facts and figures from text books, they are much more likely to gather pertinent knowledge and retain that knowledge.

Recalling what you have learned: there is a difference between retaining what you have learned to short term memory and recalling what you have learned years later. Undertaking problem solving tasks and projects are much more likely way to commit information to long term memory. We consider that, along with a passion for what they are studying, to be the key reason our students do so well in their courses, our courses are based on a Problem Based Learning system. Problem based assignments and practical set tasks mean that students have to work at finding solutions and developing skills. These may come from various sources - in the process they gather knowledge through experiential learning, which ismore likelyto be retained in long term memory.   

So although a course and qualification won’t necessarily get you a job – choosing the right course and learning the right things will certainly help.
