Track 2-11: Plant Nutrition and Nutrient Cycling

Description

Australian soils are generally low in phosphorus (P) by world standards and require applied P to reduce this limitation on plant growth. In grazing systems P is deposited on the soil surface from fertiliser, livestock excretion and senescing pasture. Phosphate occurs in many forms in soils. Because of rising fertiliser prices there is growing interest in assessing and improving the availability of accumulated soil P.

The objective of the research described here was to identify and quantify the forms of P in soils under permanent grasslands with a wide range of soil P status.

Forms of Soil Phosphorus Accumulation in Grassland Soils

Australian soils are generally low in phosphorus (P) by world standards and require applied P to reduce this limitation on plant growth. In grazing systems P is deposited on the soil surface from fertiliser, livestock excretion and senescing pasture. Phosphate occurs in many forms in soils. Because of rising fertiliser prices there is growing interest in assessing and improving the availability of accumulated soil P.
