A visitor from down under

We had the privileged of welcoming Dr Tim McLaren, Research Fellow in soil nutrient dynamics at the University of Adelaide, Australia on Tuesday. Tim presented some recent data on the fate of fertilser P using P-33 labelled single superphosphate in clover pasture systems. The team were able to identify the amount of fertiliser P that was recovered in clover shoots and roots, what remained in the granule, and in soil fractions as either inorganic or organic P, under different fertiliser management treatments (placement, timing and initial soil P fertility) (results to be published). He also discussed some of his data on the speciation of organic P in soils under pasture using solution P-31 NMR spectroscopy. It was a great meeting, full of discussion, followed by great food and drink in the pub later!
