| Abstract | Legumes can increase the growth and P (phosphorus) uptake of the following cereals which may be related to mobilization of P during the growth of the legumes. This study is part of a project to investigate the mechanisms by which legumes increase growth and P uptake of the following wheat. In a pot experiment, faba bean, chick pea, narrow-leafed lupin, yellow lupin and white lupin were grown in a loamy sand soil with low P availability (resin P 4.5 mg P/kg) with addition of 80 mg P/kg as KH 2PO 4 and harvested at flowering and maturity. At maturity, growth decreased in the following order: faba bean > chickpea > narrow-leafed lupin > white lupin > yellow lupin. The depletion of labile P pools (resin P and NaHCO 3-Pi) was greatest in the rhizosphere of faba bean, while sparingly available P pools, particularly residual P, were most strongly depleted in the rhizosphere of white lupin. The results suggest that these legumes could differentially affect the dynamics of organic and inorganic P pools and the capacity of the following wheat to utilise these pools. |
