“…For example, Moore and Edwards (2007) monitored two catchments since 1995 and found that, in one with poultry litter applied, much more P (1.5 kg P ha −1 yr −1 ) was lost than from an adjacent catchment with applied poultry litter amended with alum (0.45 kg P ha −1 yr −1 ). Recent research in Ireland has shown that mixing alum with dairy‐soiled water (e.g., dairy shed effluent) or pig slurry can decrease concentrations and loads of FRP, TP, ammoniacal‐nitrogen, and suspended solids in runoff generated by rainfall simulation onto ungrazed grassland (Brennan et al, 2011, 2012; Fenton et al, 2011; O'Flynn et al, 2012, 2013; Serrenho et al, 2012). …”

Phosphorus (P) loss from land can impair surface water quality. Aluminum sulfate (alum)‐treated, compared with untreated, manure or slurry decreases P loss when applied to land; our hypothesis was that alum may also decrease P loss when directly applied to grassland grazed by dairy cows. A rainfall simulation showed that alum decreased mean concentrations of filterable reactive P (FRP) by 25 to 70% and total P (TP) by 20 to 40%, depending on soil P, Al, and Fe concentration and alum application rate. Using these factors, we predicted that FRP losses would be significantly less from alum‐treated grasslands than from untreated grasslands for 70 to 96 d. A 14‐mo field trial compared runoff P losses from plots that received 0, 25, and 50 kg Al ha−1 applied within a week of grazing by dairy cattle in spring. Runoff‐weighted concentrations (and loads) of FRP and TP decreased in alum‐treated plots by 47 to 52% and 25 to 34%, respectively. At US$157 to US$944 kg−1 P mitigated, cost‐effectiveness was estimated as medium to low compared with existing strategies for mitigating P loss in dairy farms but could be improved if applied to critical source areas of P loss. However, additional work, such as determining the need for repeat applications, is required before alum can be recommended to decrease P losses from grazed grassland.

“…Other studies (Brennan et al 2011;Fenton et al 2011;O' Flynn et al 2011) have used a combination of batch experiments, agitator experiments and runoff box experiments (together with isotherm parameterisation) to ascertain application rates and effectiveness of amendments when added to animal manures. The feasibility of amendments in such studies was based on cost of application, pollution swapping potential and changes to the soil or slurry caused by amendment, e.g.…”

“…One way of immobilising this P before discharge to a surface waterbody is to amend soil in a riparian zone with a material that has a high P sequestration capacity. Iron-rich materials have been used to sequester P from wastewater (Gallimore et al 1999;Elliott et al 2002;Rhoton and Bigham 2005;Johansson-Westholm 2006;Brennan et al 2011;Fenton et al 2011). The capacity of ochre to sequester P from agricultural and municipal wastewater has previously been investigated for ochre from coal mining areas of the UK (Bozika 2001;Heal et al 2005;Dobbie et al 2009), the USA (Sibrell et al 2009) and metal mining areas of south east Ireland (Fenton et al 2007).…”

“…The application of P-immobilising materials (alum, water treatment residuals, fly ash and gypsum) to such vegetative buffers (or filter strips) through amendment of edge-of-stream soils, is one possible means of reducing soluble P losses to aquatic systems (Penn et al 2007;Wagner et al 2008;Brennan et al 2011;Fenton et al 2011). In Ireland, soils receiving inorganic fertilizers as part of the Nitrates Directive (SI 610 of 2010) must maintain vegetative buffer zones at a minimum of 1.5 m in width from river bank edge.…”

Incidental losses of dissolved reactive phosphorus (DRP) to a surface waterbody originate from direct losses during land application of fertilizer, or where a rainfall event occurs immediately thereafter. Another source is the soil. One way of immobilising DRP in runoff before discharge to a surface waterbody, is to amend soil within the edge of field area with a high phosphorus (P) sequestration material. One such amendment is iron ochre, a by-product of acid mine drainage. Batch experiments utilising two grassland soils at two depths (topsoil and sub-soil), six ochre amendment rates (0, 0.15, 1.5, 7.5, 15 and 30 g kg-1 mass per dry weight (dwt) of soil) and five P concentrations (0, 5, 10, 20 and 40 mg L-1) were carried out. A proportional equation, which incorporated P sources and losses, was developed and used to form a statistical model. Back calculation identified optimal rates of ochre amendment to soil to ameliorate a specific DRP concentration in runoff. Ochre amendment of soils (with no further P inputs) was effective at decreasing DRP concentrations to acceptable levels. A rate of 30 g ochre kg-1 soil was needed to decrease DRP concentrations to acceptable levels for P inputs of ≤ 10 mg L-1, which represents the vast majority of cases in grassland runoff experiments. However, although very quick and sustained metal release above environmental limits occurred, which makes it unfeasible for use as a soil amendment to control P release to a waterbody, the methodology developed within this paper may be used to test the effectiveness and feasibility of other amendments. 1The Effectiveness and Feasibility of using Ochre as a Soil immobilising DRP in runoff before discharge to a surface waterbody, is to amend soil 17 within the edge of field area with a high phosphorus (P) sequestration material.

Dairy processing wastewater treatment sludge (DPWTS) is applied to grassland to recycle valuable nutrients and organic matter. Until recently the chemical composition of the dominant DPWTS types (calcium, aluminium or iron rich) was unknown, but the latest study (Ashekuzzaman et al. in J Clean Prod 230:1266-1275 indicates that DPWTS has high nitrogen (N) and phosphorus (P) content and their inherent chemical properties may influence their availability and losses. Herein for the first time edge of field-losses and plant-available P changes are simulated in an agitator test 48 h after application. In terms of overall losses, metals are not of concern across treatment types, iron-rich DPWTS has the highest losses in terms of concentration of ammonium-N and carbon, whereas calcium-rich DPWTS has the highest dissolved reactive P (DRP) losses but lowest losses of ammonium-N and carbon. The loss of DRP was found to be strongly positively associated with the increase in water-extractable P, degree of P saturation, Morgan's and Mehlich-3 extractable phosphorus (P m , M3-P), respectively. Runoff concentrations presented here represent edge of field-losses and may not represent final concentrations entering a surface waterbody. In terms of plant-available P, there were no negative effects with P m exhibiting a positive trend across DPWTS types and soils. In particular, a significant increase was found for the calcium-rich DPWTS across all soils (average increase in P m by fivefold). As applying DPWTS to grassland is an understudied area, further field trials should focus on emissions to air and water and examine the fertilizer value from N and P perspectives. Thus a better management of DPWTS as fertiliser can be maintained from an agronomic and environmental context.
