What else can impact my phosphorus use efficiency?
MLA-funded research indicates that legumes vary in their capacity to utilise phosphorus, with some legumes (such as serradella) outperforming others (such as sub-clover) at comparable soil phosphorus levels.
Soil-borne root disease is widespread across Australia and impacts significantly on sub-clover production.
Poor nodulation of legume pastures can impact their productivity and phosphorus use efficiency.
Soil acidity (and associated aluminium toxicity) could be limiting pasture utilisation of phosphorus.
