P.  aMycorrhizae, crop growth, and crop phosphorus nutrition in maize-soybean rotations given various tillage treatments.h[electronic resource]  c1999  aPreviously, tillage has been found to reduce early-season phosphorus (P) uptake from soil in continuous maize cropping systems. This reduced P uptake has often been associated with delayed colonization of toots by arbuscular mycorrhizal (AM) fungi. Our aim was to determine if similar responses occur in maize-soybean rotations, which are more typical of current farming in Ontario, Canada. Similar responses were expected because both are AM crops, and the mechanism by which tillage reduces P uptake is thought to be a negative impact on the development of effective mycorrhizae.  aSolo1 aMILLER, M.
