SA's premier field cropping trial site. Hart is South Australia’s premier agronomic field site, managed by farmers and ag industry professionals to provide independent information and skills to the broadacre cropping industry. 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 annual trials are show-cased throughout each growing season on site at our Winter Walk in July, main Field Day in September, and at our Spring Twilight Walk in October. Our annual Getting The Crop In Seminar is also not to be missed.
