Maltais-Landry, E. Frossard] Background and aims: Cover crops provide benefits in agricultural systems with high P availability (i.e., optimal or excessive soil P for plant growth) by reducing losses of soil phosphorus (P) via erosion and leaching, and potentially by increasing soil P availability when P is released during residue decomposition. We quantified P transfer from cover crop residues to soil pools and a subsequent wheat crop in a greenhouse experiment. Methods: Soils from two field experiments in California (Davis and Salinas) were labeled with carrier-free 33P and amended at a rate of 15mg P kg−1 soil with cover crop residues (rye, oat, fava bean, vetch, mustard, rye-legumes mixture) or water-soluble mineral fertilizer. We analyzed plants and several soil pools - resin, microbial, and organic - for P and 33P. Results: In both soils, residues and water-soluble mineral fertilizer had a similar effect on soil pools and wheat P uptake, except for higher microbial and organic P with residues in the Davis soil. Residues contributed 35-40% (Davis) or 20-25% (Salinas) of the P taken up by wheat, and 13-22% (Davis) or 8-14% (Salinas) of residue P was recovered in wheat. Conclusions: Our results demonstrate that P taken up by cover crops can cycle rapidly in agricultural systems with high soil P availability, with direct benefits for soil P availability and few differences among these cover crop species.
