TRIBUTES / ACKNOWLEDGEMENTS
The intent of the articles I write for this web site is to educate people. It is (I trust) a tribute to the many people who have contributed to my education; people who have freely given their time and shared their knowledge without the expectation of personal reward. My encouragement to you is to look for opportunities to share your knowledge and help others along their way.
At the risk of offendng someone by omission or inclusion, I would like to acknowledge and thank some of my more significant teachers: My Mum, the woman who gave me life, love and my basic values for life. Skip Goodchild (Scout Master) for moulding those values during my early teenage years. Peter Ewing (Orbital Engine Company) for management and life skills. Steve Peck (Hydroscapes Australia) for giving me my basic irrigation education and then being there for advice ever since. Ed Johnson (Rain Bird) who provided me information, training and help in my formative irrigation years in Singapore. Rick Reinders (Watertronics) who taught me the fundamentals of pumps and T.F. Mok (Flowtronex) for adding to that. Kenne James (Toro) for many in-depth technical dissertations and discussions. David Hanby (Irrigolf) for sharing his field experience and viewpoints. Tom Lubin for fertigation and chemistry (plus life and basketball). And many others I have not listed but (hopefully) not forgotten.
And finally my family; my wife Erida who gives me love, support and our four beautiful children; Michael, Michelle, Frederik and Felicity.

Description |
Basic Irrigation Parameters Series - The Fundamentals for Everyone | ||
| 1 | Sprinkler Coverage | The First Basic Irrigation Parameter.
This article explains sprinkler coverage including the concept of percentage spacing; width of coverage for golf courses (single, two-row, three-row and wall to wall) with plenty of graphics to help your understanding. |
| 2 | Peak Application | The Second Basic Irrigation Parameter.
This article covers EvapoTranspiration (ET), Reference ET (ETo), Peak Application (Precipitation) and Crop Factor for the irrigation system. |
| 3 | Watering Window | The Third (and final) Basic Irrigation Parameter.
This article lists the factors affecting the irrigation watering window. It also ties all the 3 Basic Irrigation Parameters together. It highlights the importance of correctly determining them and demonstrates their inter‑relating nature. |
Irrigation Efficiency Series - Towards the Goal of "Using Only What We Need" | ||
| 4 | Sprinkler Uniformity | The First in our series on Irrigation Efficiency
Sprinkler Uniformity is the cornerstone of Irrigation Efficiency. This article includes an introduction to Sprinkler Uniformity concepts, measurement and its importance. It also looks at computer modelling (with densograms) and a case study. |
| 5 | Distribution Uniformity | This is a practical guide (especially for Ground Staff) to measuring the Distribution Uniformity of an irrigation system. It also covers the importance of "Setting Sprinklers to Grade" and how to do it. |
Pumps and Ancillary Equipment Series - Pump Stations, Pumps, Filters, Fertigation, etc | ||
| 120 | Golf Course Irrigation Pump Stations | We look at the components of an Irrigation Pump Station for a golf course: Pumps, Motors, Manifold & Valves and the Pump Control System. The benefits of the different types of pumps is explained. Total Cost of Ownership compared to the up-front capital cost are compared.
Did you know it is likely more will be spent on electricty than the up-front capital cost? Read about how critical pump and motor efficiency are. |
