Abstract
The research presented crop yield,phosphorus dynamic for a wheat-soybean rotation systems affected by tillage management: conventional tillage(t),tillage+stubble retention(ts),no-till(nt),no-till+stubble retention(nts) in the Loess Plateau.Results showed that ten years tillage management implementation did not carry a yield penalty for winter wheat,soybean yield had a positive response to conservation tillage.Soil phosphorus content increased with the increasing of rotation sequences.Both total phosphorus and available phosphorus contents were increased at top 0-5 cm.Stubble retention increase crop phosphorus uptake,P contents in soybean grain under nts and ts treatnment were 111% and 82% higher than that under t treatment.The results provide a local agricultural implement provides certain theoretical guidance.
