Abstract

Soil testing was undertaken on 1698 pasture paddocks on 109 dairy farms across Tasmania as part of the Fert$mart planning process. Forty-five per cent of paddocks had soil Olsen P concentrations above the concentration where any response could be expected from the application of additional P fertiliser. There was uneven distribution of nutrient concentrations across farms possibly relating to different soil types, previous fertiliser applications and grazing management practices. The range in Olsen P across paddocks was 5134 mg/kg. Many paddocks (43%) had mean soil extractable K and KCl-S (39%) concentrations above that required for optimum plant growth. Only 3.7% of paddocks tested had nutrient levels in the optimum range for all of the four nutrient measures. Whole farm nutrient budgets found deficits to large surpluses for P, K and S. The Fert$mart process combines a farm nutrient budget with soil testing as tools for improved fertiliser management.
