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.

Hart - where good farmers gather

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.



What's new?

Mid North MesonetBetter weather data for spraying
Mid North Mesonet - 40 new weather stations across the region

A network of 40 automatic weather stations across the Mid North will be a ‘game changer’ for local farmers assessing suitable chemical spraying conditions and avoiding temperature inversions, or other adverse weather conditions for spraying.

 “We don’t want to stop farmers from spraying, we want them to be armed with accurate data and weather information to ensure they are spraying at the right times. This is an absolute game changer for Mid North farmers.” Peter Cousins, Mid North Mesonet committee member.

We’ll show you how to get access and interpret the data at one of 13 free workshops across the region.
