This catchment\u2010scale study was established to evaluate the impact of hydrology and BMPs on phosphorus (P) and sediment losses. Two adjacent catchments, one with a lower level of BMP adoption (Low\u2010BMP #11) and one with a higher level (High\u2010BMP #12), were compared for total P (TP) and total suspended solids (TSS) export. The BMPs include nutrient management plans, reduced tillage, grassed waterways, terraces, and perennial vegetation. The TP event\u2010flow\u2010weighted (EFW) concentration was significantly higher at Low\u2010BMP #11 (0.293\u00a0mg L<jats:sup>\u22121<\/jats:sup>) than at High\u2010BMP #12 (0.069\u00a0mg L<jats:sup>\u22121<\/jats:sup>). There was no significant difference in TP base\u2010flow\u2010weighted (BFW) concentrations between Low\u2010BMP #11 (0.035\u00a0mg L<jats:sup>\u22121<\/jats:sup>) and High\u2010BMP #12 (0.037\u00a0mg L<jats:sup>\u22121<\/jats:sup>). The TSS\u2010EFW (148.0\u00a0vs. 18.6\u00a0mg L<jats:sup>\u22121<\/jats:sup>) and TSS\u2010BFW (13.3\u00a0vs. 6.9\u00a0mg L<jats:sup>\u22121<\/jats:sup>) concentrations were also higher at Low\u2010BMP #11 than at High\u2010BMP #12. High\u2010BMP #12 had lower TP (0.36\u00a0vs. 0.59\u00a0kg ha<jats:sup>\u22121<\/jats:sup>\u00a0yr<jats:sup>\u22121<\/jats:sup>) and TSS (253\u00a0vs. 1,961\u00a0kg ha<jats:sup>\u22121<\/jats:sup>\u00a0yr<jats:sup>\u22121<\/jats:sup>) loading than Low\u2010BMP #11. The lower TP export at High\u2010BMP #12 was likely attributed to the effectiveness of stacked erosion control BMPs and nutrient management plans. Overall, lower P and sediment loading was observed when a greater areal extent of stacked practices was implemented at the catchment level. This finding provides vital information to encourage wider BMP adoption at the watershed scale.<\/jats:p>","DOI":"10.1002\/jeq2.20140","type":"journal-article","created":{"date-parts":[[2020,8,28]],"date-time":"2020-08-28T02:07:41Z","timestamp":1598580461000},"page":"1552-1563","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Impact of stacked conservation practices on phosphorus and sediment export at the catchment scale"],"prefix":"10.1002","volume":"49","author":[{"given":"Ji Yeow","family":"Law","sequence":"first","affiliation":[{"name":"Dep. of Agricultural &amp; Biosystems Engineering Iowa State Univ.
