“…The observed background (control) TDP concentration of the shallow wells of the study site (0.6–0.8 mg TDP mg L −1 ) exceeded the critical P solution concentration (0.10 mg L −1 ) guidelines established for streams (USEPA, 1986b). However, the ground water P concentrations were similar to the upper limits of ground water P concentrations observed by others in Florida (0.1–0.7 mg TDP mg L −1 ) (Woodard et al, 2007) and elsewhere (0.05–0.6 mg TDP mg L −1 ) (Nelson et al, 2005). The elevated ground water P concentration possibly resulted from decades of intensive dairy cattle production at the site (Kenneth R. Woodard, personal communication, 2007).…”

Efficacy of Drinking‐Water Treatment Residual in Controlling Off‐Site Phosphorus Losses: A Field Study in Florida

et al. 2009

Land application of drinking-water treatment residuals (WTR) has been shown to control excess soil soluble P and can reduce off-site P losses to surface and ground water. To our knowledge, no field study has directly evaluated the impacts of land application of WTRs on ground water quality. We monitored the effects of three organic sources of P (poultry manure, Boca Raton biosolids, Pompano biosolids) or triple superphosphate co-applied with an aluminum-based WTR (Al-WTR) on soil and ground water P and Al concentrations under natural field conditions for 20 mo in a soil with limited P sorption capacity. The P sources were applied at two rates (based on P or nitrogen [N] requirement of bahiagrass) with or without Al-WTR amendment and replicated three times. Without WTR application, applied P sources increased surface soil soluble P concentrations regardless of the P source or application rate. Co-applying the P sources with Al-WTR prevented increases in surface soil soluble P concentrations and reduced P losses to shallow ground water. Total dissolved P and orthophosphate concentrations of shallow well ground water of the N-based treatments were greater (>0.9 and 0.3 mg L(-1), respectively) in the absence than in the presence ( approximately 0.6 and 0.2 mg L(-1), respectively) of Al-WTR. The P-based application rate did not increase ground water P concentrations relative to background concentrations. Notwithstanding, Al-WTR amendment decreased ground water P concentrations from soil receiving treatments with P-based application rates. Ground water total dissolved Al concentrations were unaffected by soil Al-WTR application. We conclude that, at least for the study period, Al-WTR can be safely used to reduce P leaching into ground water without increasing the Al concentration of ground water.

“…2A), and from 0.5–0.7 mg L −1 for the deep wells (data not presented). The observed PO 4 –P concentration of the shallow wells exceeded those observed by others in Florida (0.1–0.7 mg P mg L −1 , Woodard et al, 2007) and elsewhere (0.05–0.6 mg P L −1 , Nelson et al, 2005). However, high groundwater P concentrations are common from fields subjected to long term disposal of manure (0.4–0.9 mg L −1 , Breeuwsma et al, 1995) and sewage (0.3–1.5 mg L −1 Corbett et al, 2001).…”

A gronomy J our n al • Volume 101, I s sue 6 • 2 0 0 9 1345 ABSTRACT Phytoremediation or use of plants to extract soil nutrients is a practice used to ameliorate the impacts of excessive soil nutrients. Pensacola bahiagrass (Paspalum notatum Flügge) and 'Floralta' limpograss [Hemarthria altissima (Poir.) Stapf & Hubb] were grown in a P-impacted Immokalee fi ne sand (Mehlich-1 P ≈ 30 mg P kg -1 ) to evaluate increasing N levels on dry matter yield (DMY), forage P concentration, P removal, and P dynamics in the soil profi le. Treatments were four levels of N fertilization (0, 50, 67, and 101 kg N ha -1 harvest -1 ) replicated four times for each species. Both grasses showed increases in P removal with increasing N fertilizer applications. Phosphorus removed by forages for the highest N application level ranged from 59 (bahiagrass; 2-yr period) to 83 kg ha -1 (limpograss; 3-yr period). Th e initial soil P content of the Ap horizon of all N > 0 treatments decreased by ≥85% over the study period. However, more P from the control (N = 0) plots leached to subsurface horizons compared to P lost from the plots receiving N fertilizer. Nitrogen application enhanced P uptake from the soil and consequently reduced off -site P losses from the surface soil. Nitrogen application of 67 kg ha -1 harvest -1 optimized P removal by bahiagrass and limpograss. Th ese data show that well managed, warm-season perennial forage grasses with adequate N fertilization and managed for hay production or greenchop are an option for reducing off -site P losses from P-impacted soils.

Biosolids, materials resulting from domestic sewage treatment, are surface applied to forest soils to increase phosphorus (P), nitrate, and ammonium availability. Retaining streamside management zones (SMZs) can limit nutrient pollution of streams. We delineated 15-m SMZs along three intermittent streams in an 18-yr-old Pinus taeda L. plantation. We applied biosolids at a rate of 1120 and 629 kg ha(-1) of total nitrogen and total P outside the SMZ on one side of each of the streams while maintaining the other side of the stream as control. We collected water samples from the three treated and six reference streams and from the perennial stream upstream and downstream from the intermittent streams for 12 mo after treatment. Along transects perpendicular to the treated streams, we collected overland flow samples, soil solution samples at 60 cm, and extracts from ion exchange membranes (IEMs) placed in the surface soil. We observed significantly elevated P concentrations adjacent to the stream in overland flow during one period on the treated side of the stream. We found significantly elevated nitrate concentrations outside the SMZ in the treated-side soil solution samples, in which concentrations remained below 1.5 mg L(-1). Phosphorus, nitrate, and ammonium concentrations outside the SMZ in treated-side IEM extracts showed significant increases after biosolids application, returning to near control levels after 1 yr. Phosphorus, nitrate, and ammonium concentrations in IEM extracts were not different adjacent to the streams. Stream P, nitrate, and ammonium concentrations showed few differences downstream from the treatment with concentrations below 1.5 mg L(-1). Our results indicate that at 15 m, SMZ protected streams from P, nitrate, and ammonium pollution for the first year after biosolids application to adjacent loblolly pine plantations in the Virginia Piedmont.
