James Hook: McLaren Vale and the Barossa have historically been port
and later wine production areas. Our vineyards have old vine material left
over from that time.                                                          Small berry size is desirable in Shiraz grapes for winemaking. Smaller

Shiraz responds well to RDI irrigation. It has the effect of making the vine
work hard and keep the berries small. The trick with RDI irrigation is after
stressing or limiting the vines, is to then bring them back. This keeps the
leaves healthy and supplying the fruit with energy. Leaves ripen fruit!

Why does an agricultural supply company like Landmark have
specialist wine industry staff. Don’t viticulturalists normally
work for wineries?

James Hook: In growing grapes and making wine the biggest problem
you will have is getting lost in the advice that everyone gives you. It is also
important to have some specialists in the industry who are independent
of the winery system. An important advantage we offer our growers is
we can liaise on their behalf with wineries. The wineries seem to like this
approach as we offer highly skilled opinion as one specialist to another.
We let the winery know the grower’s goals and that they, the winery, are
welcome to give opinion on techniques etc. Wineries aren’t in the business
of giving advice, so when they do we ensure the growers understand
their recommendations as this is in everyone’s best interest. We offer
specialist services like moisture monitoring, nutrition and of course pest
and disease advice.

I am proud to be able to offer this service. I have great pride working for
Landmark because it lets me help a lot of people.

The software calculates nutrient requirement based on soil tests and a
range of other parameters and recalculates the nutrient requirement for
each critical crop growth stage following Sap and QuickSoil tests. This
takes into account changed nutrient levels and crop conditions, caused by
recent applications of fertilizer, leaching, or crop usage.

The application rates and nutrient ratios vary between crops and growth
stages and is recalculated if yield potential is compromised by poor fruit
set or other restrictions.

The package incorporates diagnostic tools such as plant symptom
recognition and diagnosis of sap nutrient changes caused by growth
restricting influences like soil moisture, nutrient imbalances, or extreme
weather conditions.
