The BFDC database holds extensive historic data for 4036 key nitrogen (N), phosphorus (P), potassium (K) and sulphur (S) trials for different grain crops and soil types from over 1240 geographic locations across Australia. Each trial has a soil test and relative grain yield data that enable users to determine the critical soil test values for a range of management and growing conditions. These include farming system, growing season rainfall and paddock history.
The trial sites are geo-referenced within the the database. A user can specify trials of any geographic area by drawing a polygon on the map. Map layers showing rainfall isohyets, crop yield maxima, trial soil type, and nutrient responsiveness can assist the user to best judge the geographic area of interest.
The Interrogator helps users to interpret soil test results for N, P, K and S. It does not provide a fertiliser recommendation. All users are encouraged to consult a Fertcare Accredited Advisor for fertiliser management advice.
The BFDC project is supported by the Grains Research and Development Corporation. It is led by NSW DPI and includes substantial collaboration with the fertiliser industry, consultants, state and federal agencies, agribusiness, and universities. These collaborators have contributed the data held in the database.
