EXTRACT OF COURSE NOTES

Soil Uniformity

The more uniform the irrigation block, the easier it will be to manage. Problems of patchiness can arise, for example, in hand forming when a cut is made into subsoil that is more clayey or more sandy than the topsoil. So, it is necessary to level the land and examine the soil to the depth of the maximum cut to determine the likely effect on soil texture.

Available soil water capacity

A high available soil water capacity is desirable for crops because the higher it is, the less likely the plant is to become stressed between irrigations. The best soils are generally loams or clay loams. The soil needs to be examined to the likely maximum rooting depth both to determine the available soil water capacity and to ensure there is no bedrock, hardpan or other root impeding layers.

Infiltration

This refers to process of water entry into the soil. It is influenced by:

a) Soil type and soil texture. Sandy soils generally have higher long term water penetration rates than clayey soils.

b) The condition of the surface soil. Water will enter faster if the soil surface is friable and open or is extensively and deeply cracked. Compacted or crusted soil with few cracks has a low infiltration rate.

c) The stability of the surface soil. Low water stability means that the soil crumbs do not stay together when wetted. Low water stability results in slow water penetration unless the soil is sandy. Also, it often results in the formation of a surface crust as the soil dries which will reduce infiltration at the next irrigation.

d) Depth of soil above an impermeable layer. The soil may consist of a light loam topsoil over a clay subsoil or bedrock. In this case, water up over the impermeable layer reduces water penetration.

Why Choose This Course

  • Unique course materials (developed by our staff) and more current than some colleges (many reviewed annually); as a result, ACS graduates can be more up to date.
  • We work hard to help you understand and remember it, develop an ability to apply it in the real world, and build networks with others who work in this field (It’s more than just serving up a collection of information –if all you want is information, buy a book; but if you want an education, that takes learning to a whole new level).
  • Start whenever you want, study at your own pace, study anywhere
  • Don’t waste time and money traveling classes
  • We provide more choices–courses are written to allow you more options to focus on parts of the subject that are of more interest to you; a huge range of elective subjects are offered that don’t exist elsewhere.
  • Tutors are accessible (more than elsewhere) – academics work in both the UK and Australia, 5 days a week, 16 hours a day. Answering emails and phone calls from students are top priority.
  • We treat students as individuals –don’t get lost in a crowd. Our tutors communicate with you one to one.
  • Extra help at no extra cost if needed. When you find something you cannot do, we help you through it or will provide another option.
  • Support after you finish a course –We can advise about getting work, starting  business, writing a CV, etc. We can promote students and their businesses through our extensive profile on the internet. Graduates who ask will be helped.
  • Support from a team of a dozen professional horticulturists, living in different parts of the UK, and in both temperate and tropical climate zones of Australia.

About ACS

ACS was started in 1979 by John Mason, who at the time was a gardening author, horticultural consultant and lecturer in horticulture at several colleges across Melbourne (in Australia).  Over the summer that year John discovered that there were thousands of applicants going to be turned away from horticulture courses at Burnley Horticultural College (now Melbourne University). There were simply too few courses being offered for the number of people wanting to study horticulture in Australia. This situation prompted a move to establish a correspondence course at Burnley; but after months of unsuccessful lobbying for support from government; John wrote a course, and with help from a colleague at Council of Adult Education, marketed it.

Standards were originally set in line with what were seen to be the standards of Australia's top horticultural college; and over the years, those standards have never been reduced. This makes our courses longer and more demanding than some other colleges; but it has also led to us building a credibility that stands tall in the horticulture industry across the world. 

In the early 1990's John started visiting the UK and becoming involved with the horticulture industry there. Around the mid 1990's ACS began offering RHS courses, and in 2003, John was formally recognised for his contribution to British Horticulture by being made a fellow of the Institute of Horticulture. ACS, as a school, established an office and staff in the UK in 2001, and has expanded considerably since then. Today it is formally affiliated with five other colleges in the UK (including Warwickshire College); all of who license and deliver ACS courses. 

A team of leading horticulturists work for the school's horticulture department, including 12 faculty members in both the UK and Australia

 

How You Study

  • As soon as you enroll, we send an email to explain it all.
  • We direct you to a short orientation video (downloadable over the internet) to watch, where our principal introduces you to how the course works, and how you can access all sorts of support services
  • You are either given a code to access your course online, or sent out a CD or course materials through the mail (or by courier).
  • Work through lessons one by one, each lesson typically having four parts:
    • An aim -which tells you what you should be achieving in the lesson
    • Reading -notes written and regularly revised by our academic staff
    • Set Task(s) -These are practicals, research or other experiential learning tasks that strengthen and add to what you have been reading
    • Assignment -By answering questions, submitting them to a tutor, then getting feedback from the tutor, you confirm that you are on the right track, but more than that, you are guided to consider what you have been studying in different ways, broadening your perspective and reinforcing what you are learning about
    • Other - Your work in a course rarely stops at just the above four parts. Different courses and different students will need further learning experiences. Your set task or assignment may lead to other things, interacting with tutors or people in industry, reviewing additional reference materials or something else. We treat every student as an individual and supplement their learning needs as the occasion requires.
  • We provide access to and encourage you to use a range of supplementary services including an online student room, including online library; student bookshop, newsletters, social media etc.
  • We provide a "student manual", that is a quick solution to most problems that might occur

Extra Books or Reference Materials

  • The course provides you with everything that you need to complete it successfully.
  • Assignments may ask you to look for extra information (eg. by contacting nurseries, visiting gardens or searching the internet), but our school's resources and tutors are always available as a back up. If you hit a "roadblock", we can quickly send you additional information or provide expert advice over the phone or email; to keep you moving in your studies.
  • Some students choose to buy additional references, to take their learning beyond what is essential for the course. If a student wants to buy books, we operate an online bookshop offering ebooks written by staff at the school. Student discounts are available if you are studying with us. The range of e books available is being expanded rapidly, with at least one new ebook being written and published by our staff every month.
  • See www.acsebook.com  for ebooks (available in pounds stirling). We also sell books through our Australian bookshop (selling in Australian dollars) at www.acsbookshop.com
