It's never easy to get farmers to part with their hard-earned cash but one thing those attending the dairy conference in Limerick last week were willing to open the wallet for was the new Teagasc drainage manual.
Perhaps it was the memory of last year's dreadful summer that sparked farmer interest in the manual, but the publication sold like hot buns at the event.
The manual was edited by Mark Moore and is similar in appearance to the very successful dairy manual that was published by Teagasc a few years ago.
It is priced at €40 but is available to Teagasc clients for €20 from any Teagasc office or by post.
However, in the case of the latter, there is an extra charge of €7.50 for postage and packing.
One thousand copies of the manual have been printed and if last week's conference was anything to go by, Teagasc won't have any problems selling them.
The manual includes six sections. The first, on rainfall, landscape and soils, is written by Tristan Ibrahim, Rachel Cremer and Owen Fenton.
It deals with the influence of topography and soil type on drainage.
Dermot Forristal and Bruce Ball outline how to manage wet and weak soils in the second section, while working with livestock on heavy land is covered by Ger Courtney and John Maher.
An outline of the legislation and environmental regulation governing drainage is set out in the third section of the manual, while the various drainage systems are covered in section four.
The cost and economics of land drainage, running a drainage project and maintaining a drainage system are dealt with in the final two sections of the manual.
