Principles of Irrigation Scheduling

By Adrian Orloff. MAIT Industries, Shepparton (Talk presented at AFFCO / CGA / VCA Workshop Euroa 7 March 2008)
The basic issues to be considered and monitored to develop and manage an irrigation schedule are outlined below.

Positioning monitoring sites
Monitoring sites need to be selected carefully in order to allow for soil and crop variations.

Positioning monitoring sites within the average soil types will reduce the risk of the better soils being under-watered and the worse soils being over-watered.

Ideally, a soil survey at the time of the irrigation development will provide you with the information on soil variations. The information collected from the survey will allow you to plan the irrigation system according to soil variations, and position monitoring sites in representative locations.

Positioning monitoring sites in relation to the crop and irrigation system are also important considerations. Care should be taken to ensure that the site will record both representative water use of the plant(s) and wetting from the irrigation system. There are a number of factors that need to be taken into account such as plant spacing, crop type and soil type.

Soil Moisture Monitoring - How and Why?

By Adrian Orloff. MAIT Industries, Shepparton (Talk presented at AFFCO / CGA / VCA Workshop Euroa 7 March 2008)
What does irrigation farming mean? It means applying water to a crop in order to supplement water requirements not met by rain, in order to grow the maximum yield and quality of the desired plant product.

Knowing how much water to apply and when to apply it is a fundamental management decision on which effective water management practices should be based. However very few irrigation farmers are using such technology. About 4% in Australia.

Choosing an Orchard irrigation system

(Agricultural Note published by Victorian Department of Primary Industries. Written by Peter Jerie, DPI Tatura)
An inevitable question posed at field days after the various types of orchard irrigation systems have been described is, "Well, now we know how the different methods operate but which is best for me?"

Unfortunately there is no clear-cut answer to this question because no two situations are the same. Factors such as soil type, crop type, planting density, water quality, irrigation equipment at hand, and economic factors such as the capital cost and operating cost, will all determine the ultimate decision.

This Agriculture Note discusses the most important factors that should be considered when making a choice between the various forms available.

Micro-irrigation systems that apply water to only part of the soil surface (for example, trickle, microspray or microsprinkler) have a number of advantages over more conventional methods of irrigation. These advantages are described below.
