“…LID collects runoff close to the source in small structures, generally in urban areas. While costs can be modest, individual LID projects infiltrate relatively little:~10 3 m 3 /yr (~1 ac-ft/yr) (Stephens et al, 2012;Grebel et al, 2013;Newcomer et al, 2014;Bhaskar et al, 2016;Chen et al, 2016). Regional spreading grounds infiltrate excess surface and/or recycled water from large regions, collecting and routing water with dams and other large infrastructure.…”

“…The Sac soil mix had significantly higher levels of Al, which likely sorbed some of the P. The Killduff soil mix had higher levels of Mehlich-3 extractable P and DTPA-extractable Fe, and the Sac soil mix had higher levels of NO 3 and NH 4 , which may represent fertilization differences. Lower ratios (P over Al + Fe or P over Ca) indicated greater potential sorption capacity for P. When averaged across soil mixes (Table 3), those with a compost blanket had significantly higher readily available Fe (DPTA), ortho phosphate, DPS and ratio of P over Ca, organic carbon, total nitrogen, and nitrate.…”

“…Studies on bioretention cells [3,33] often show low effluent nitrate concentrations (<1 mg L −1 ). Bratiers et al [34] reported lower nitrate concentrations if plants were grown compared to no plants.…”

“…Reagent-grade sand is often a large component of engineering soil mixes used in bioretention cells where plants are grown; however, sand has low water holding capacity, cation exchange capacity, nutrient levels, and nutrient sorption capacity [1][2][3] than soil. Sometimes, sorbents [4,5] are added to sand to increase P retention, especially in filters in which no plants are growing.…”

“…Soils with varying P sorption capacity can be used as sorbents in engineered mixes [3,7,8]. Just a little fine-textured soil, clay, or oxides of aluminum (Al) or Fe decreased P leaching compared with sand substrate containing organic material [1,9,10].…”

Soils can serve as sorbents for phosphorus (P), negating the need for artificial sorbents. The purpose of this study was to compare soils with different properties for their effect on nutrient levels in effluent. Four soils were mixed with sand and packed into columns 0.5 m long, with or without compost on the surface. Infiltration and effluent concentrations were measured before and after growing plants [Buffalograss (Buchloe dactyloides (Nutt.) Engelm.) and bluegrama grasses (Bouteloua gracilis H.B.K.) and red clover (Trifolium pratense L.)]. The growth media with compost at the surface had higher nutrient levels than the media without the compost, but the final effluent nitrate concentrations post-harvest were significantly lower for columns with the compost blanket (59 vs. 86 mg L −1 ). All of the nitrate concentrations were high (many >100 mg L −1 ) due to mineralization and nitrogen fixation. The final effluent P concentrations before planting were significantly higher in the soil with the most sand (0.71 mg L −1 ), and after harvest in the mixture that contained the high soil P levels (0.58 mg L −1 ). Some soils (high in aluminum or calcium) were adequate sorbents for P without additions of other sorbents, but soils often generated too much nitrate in effluent.
