Fu­ture of ir­ri­ga­tion

The Western Star - - RURAL WEEKLY -

RE­CENTLY War­rego Wa­ter Ser­vices in­vited cus­tomers on a tech­nol­ogy ir­ri­ga­tion field tour through­out the Jondaryan re­gion to visit a num­ber of re­cently im­ple­mented ir­ri­ga­tion de­vel­op­ments with var­i­ous new tech­nol­ogy from the Val­ley Pivot and Lat­eral ir­ri­ga­tion prod­uct line.

Of ma­jor in­ter­est to the grow­ers on the tour was the Vari­able Rate Ir­ri­ga­tion Pivot be­ing used over this year’s cot­ton crop at Lea­haven be­long­ing to Neil Nass.

The pivot has 164 in­di­vid­ual con­trol valves and sprin­klers that can be con­trolled to ap­ply vary­ing ap­pli­ca­tions on the pivot ir­ri­gated area.

In con­junc­tion with a re­search study by the Na­tional Cen­tre of En­gi­neer­ing in Agri­cul­ture – this site has re­duced to­tal wa­ter use by the pivot by nine per cent with­out any re­duc­tions in over­all yield.

An­other site vis­ited on the field tour was Wan­tata on the Jondaryan Evanslea Rd.

Wan­tata, over the last four years, has changed dra­mat­i­cally from a fully flood ir­ri­gated block to one now con­sist­ing of 390 ha of over­head ir­ri­ga­tion.

With two Val­ley Rainger Swing Around ditch feed lat­er­als cov­er­ing sum­mer and win­ter crop ro­ta­tions – flex­i­bil­ity, re­turn on in­vest­ment, labour sav­ing, re­duced wa­ter use and yields have all been max­imised.

For this sum­mer’s cot­ton crop, which will be picked in com­ing weeks, 30 per cent less wa­ter has been ap­plied on the lat­eral ir­ri­gated coun­try com­pared to the flood ir­ri­gated coun­try with both ar­eas look­ing to yield in sim­i­lar num­bers.

On-farm cap­i­tal in­vest­ment for ma­chin­ery and in­fra­struc­ture can be dif­fi­cult to pri­ori­tise. But the de­ci­sion can be helped when look­ing at re­turn on in­vest­ment (ROI).

Wa­ter in­fra­struc­ture ROI, be it stock­wa­ter or wa­ter trans­fer and ir­ri­ga­tion, is pretty sim­ple when look­ing at all true costs from labour sav­ing, en­ergy sav­ings, wa­ter use ef­fi­ciency, yield and risk man­age­ment.

With wa­ter be­ing our most pre­cious as­set, wa­ter in­fra­struc­ture should be de­signed to give the most ef­fi­cient distri­bu­tion of avail­able wa­ter.
