Soil Phosphorus Dynamics of Wheat-Based Cropping Systems in the Semiarid Region of Argentina
Published 2014-01-01“…The coarse fraction of the reference plots had significantly higher levels of Po and Pi than the cultivated treatments, probably a consequence of the particulate organic matter decomposition and coarse mineral particle weathering. The observed changes in Pi content could be attributed to differences in occluded P equilibrium under different soil environments (mainly pH) and crop-tillage-climatic interaction.…”
