Irrigation

Definition: The controlled application of water to the turf surface.

Introduction

An important part of any pitch maintenance programme is the watering. Water should be viewed as a tool of the job. It has its place and like any tool can cause damage if misused.

The rate of water required to sustain a pitch will vary on the type of construction. Sand type constructions will require more than soil-based pitches.

It should be remembered that any new sward would need water to develop. Once developed it needs water to survive. Water is also used to enhance the speed of the ball over the surface and managers at all levels of the game prefer to play on a wet top.

Maintenance of data / records

It is useful to keep the following records when irrigating:

- Rainfall

- Amount of water used (especially if water is metered)

- l Regular weather records.

Timing

It can be fairly stated and understood that irrigation in the winter months is usually not required. However, it may be required in the spring through to August / September. Additionally irrigation during the summer months will be required to;

- Aid maintenance operations such as aeration

- Aid grass recovery after play

- Maintain healthy, vigorous grass growth

- Facilitate a level of impact absorbency

- Aid fertiliser applications

- Germinate seed

- Prevent stress

- Effect speed of ball across the pitch

Incorrect irrigation will encourage poor root structure and therefore poor stability.
