ONLINE STUDY IRRIGATION COURSE
Student Comment "This is the first correspondence course I have done and I have thoroughly enjoyed it and I just wanted to say a big THANK YOU. I appreciate everyone's effort in such a professionally-run organisation with seamless administration. The office staff's happy can-do attitude, their fast responses to all queries, tutor Shane Gould's quick turnaround in assignment marking and his supportive and motivational feedback and last but not least, the sound subject guides. Most importantly I hope my thanks and appreciation can be communicated to all the staff who have supported me long the way of my learning! I work full time and study on the weekend but really don't stop thinking about what gardening solution I need in order to answer my assignments every day of the week. Thank you for such a great learning experience and I cant wait to start the second half of my course!!"

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.

If you wish to take an individual module course as a stand alone course, you can elect to sit an optional exam at the end of it.
If you successfully pass the exam and all assignments, you will receive a Statement of Attainment. You can take examinations at a time and location to suit you. If you enrol, you will be sent further information on how to arrange examinations at the end of the course.
If you do not wish to take the exam, you will receive a Course Completion letter when you have passed all assignments.
There is an assignment at the end of each lesson. So for example, if an individual module course contains ten lessons, you will need to complete ten assignments. Assignments can be sent to us via email, post or fax.
Other qualifications, such as certificates, diplomas etc may require examinations to be taken as part of the overall assessment process.
