Welcome to Hart

Agricultural research and extension since 1982

Our Values   Our purpose   Our vision


Hart is South Australia’s premier agronomic field trial site, managed by farmers and industry professionals to provide independent research that is timely, relevant and unbiased, as well as cutting edge and innovative.

Located between Blyth and Brinkworth in South Australia’s Mid-North, Hart is situated on 40 hectares owned by the Hart Field-Site Group Inc.

Our event calendar begins with our annual Getting The Crop In seminar (March). Our trial program is then the focus of our remaining events, all held on site; the Winter Walk (July), main Field Day (September), and at our Spring Twilight Walk (October). Other workshops and demonstrations are also run to further extend research projects to growers.

Soil type
at the site is a clay loam grading to calcareous and dispersive clay. Soil pH values which are slighly alkaline are typical for the soil. A number of soil profiles in the area have been characterised for Yield Prophet and in general have a plant available water capacity (PAWC) or 'bucket size' around 180 - 200 mm.

Hart's average annual rainfall is 400 mm with an average growing season rainfall of 300 mm.

Kevin Jaeschke - Hart co-founderThe heart of Hart, Kevin Jaeschke OAM farewelled

It is with great sadness that we acknowledge the passing of one of our founders.

Kevin was such an important part of Hart's beginnings; in fact he hosted the first Hart Field Days on his farm and went on to volunteer hundreds of hours over many years to help make the Hart group what it is today.

The Hart team, both past and present, pass on our most sincere condolences to Lorna, Michael, Louise, Chris, & Graham and their families, and to his friends.

As we celebrate our 40th anniversary this year, we will remember him with respect and gratitude. RIP Kevin.

Hart intern, Declan Anderson, measuring rainfall in 2021Rainfall variability at Hart in 2021

"How much rain did you get...?"
It's a common question, but the answer is sometimes perplexing; your neighbour got 16 mm, yet you only got 10 mm.

We regularly hear growers expressing uncertainty around the varying amount of rainfall recorded across short to medium distances and we've also noticed variation across our own site at Hart.

So we set up a very simple trial to track how much variation occurs. We're presenting the data in some really easy to interprete, colour coded maps (thanks Declan!) and it's really interesting.
