Irrigation & Soil Moisture Monitoring

Location: Mermadale Orchard, 620 Heslerton Road Leeston
(off Rakaia Selwyn Road)

Details about getting there. We are 20 minutes from Leeston right at the extreme end of RD2. The address is better as either Killinchy or Bankside, but better still South out of Dunsandel on State Highway 1 – turn left (East) at the Synlait factory and we are down there about 4km, gate on left (North) after 2nd cross roads. Please park on the road side. Phone if you get lost phone 021 393932 .


With summer fast approaching and given that water stress can decrease nut size and quality, an irrigation and soil moisture monitoring field day is being held for those walnut growers wanting to take the guesswork out of how much water they should be putting on their trees.

We will be visiting two properties:

1. Brian Falkingham’s  ‘Mermadale’ Orchard. This is in an area that we haven’t had a field day in before.

Brian has 1,800 trees on 8 hectares of land, growing Meyric, Rex, Tohama and NZ purple cultivars. His 15 year old trees are grown on a hedgerow system.

Brian uses Davis soil moisture sensors. In addition, Brian will show his harvester and nut washing machine.

2. Barbara and Graeme Nicholas’ orchard at:

480 Rattletrack Road Springston
(off Selwyn Road)

Barbara and Graeme’s 10.4 hectare property has 1,200 trees aged 8 to 13 years.

They use HydroServices soil moisture sensors.

Likewise, the Nicholas’ will have their AMB Rousset self- propelled harvester available for viewing.

Come along, find out about irrigation and soil moisture and take a look at two orchards to learn how they do things.
