Abstract. Excessive delivery of phosphorus (P) from agricultural landscapes to surface waters results in water quality impairment. The method of application of broiler litter to agricultural fields significantly affects P loss to surface waters via surface and subsurface flow pathways from agricultural landscapes. Subsurface-band application of broiler litter can help reduce P loss in surface and subsurface flows. Typically, leachate samples are collected using lysimeters or subsurface flows are sampled to assess the effectiveness of subsurface-band application of broiler litter in limiting P mobility. In this study, we tested a simple and inexpensive method of assessing effectiveness of subsurface-band application of broiler litter using ortho-P (PO4-P) measurements in soils. This method of measuring PO4-P concentration in soils showed that subsurface-band application of broiler litter helps to reduce P leaching, whereas surface application of broiler litter was not effective in reducing P leaching. The results of this study show that soil PO4-P measurements can be successfully used to assess the effectiveness of subsurface-band application of broiler litter in reducing P leaching.

Kleinman, P. J. A., Sharpley, A. N., Budda, A. R., McDowell, R. W. and Allen, A. L. 2011. Soil controls of phosphorus in runoff: Management barriers and opportunities. Can. J. Soil Sci. 91: 329–338. The persistent problem of eutrophication, the biological enrichment of surface waters, has produced a vast literature on soil phosphorus (P) effects on runoff water quality. This paper considers the mechanisms controlling soil P transfers from agricultural soils to runoff waters, and the management of these transfers. Historical emphases on soil conservation and control of sediment delivery to surface waters have demonstrated that comprehensive strategies to mitigate sediment-bound P transfer can produce long-term water quality improvements at a watershed scale. Less responsive are dissolved P releases from soils that have historically received P applications in excess of crop requirements. While halting further P applications to such soils may prevent dissolved P losses from growing, the desorption of P from soils that is derived from historical inputs, termed here as “legacy P”, can persist for long periods of time. Articulating the role of legacy P in delaying the response of watersheds to remedial programs requires more work, delivering the difficult message that yesterday's sinks of P may be today's sources. Even legacy sources of P that occur in low concentration relative to agronomic requirement can support significant loads of P in runoff under the right hydrologic conditions. Strategies that take advantage of the capacity of soils to buffer dissolved P losses, such as periodic tillage to diminish severe vertical stratification of P in no-till soils, offer short-term solutions to mitigating P losses. In some cases, more aggressive strategies are required to mitigate both short-term and legacy P losses.

Low ionic sorption capacities and high hydraulic conductivities of sandy soils contribute to the potential for leaching of nutrients applied to these soils. Batch sorption experiments were used to examine NO3–, NH4+, and P sorption/desorption isotherms for Karrakatta sand and Kwinana fly ash. Column experiments assessed leaching of these nutrients from this sandy soil, when amended with 4 rates (0, 5, 10, and 20%, wt/wt) of fly ash. The sorption of NO3–, NH4+, and P was higher for fly ash than the sandy soil. Phosphorus sorption was greatest for unweathered fly ash, followed by weathered fly ash and then the soil; for example, sorption from a solution containing 20 mg/L P was 90%, 28%, and 14%, respectively. Desorption of P was much slower in the unweathered fly ash than weathered fly ash or the soil. Leachates collected from columns containing fly ash amended soil (5, 10, and 20%, wt/wt) generally had lower concentrations of NO3– and NH4+ than leachates from non-amended soil. Prior to adding fertiliser, the concentration of P was greater in leachate from fly ash amended soil than from the native soil, due to fly ash (weathered) itself containing 92.5 mg/kg of extractable P. However, from day 35 onwards, the concentration of P was lower in leachates from soil amended with 10% or 20% fly ash than from non-amended soil. Thus, fly ash amendment retarded NO3–, NH4+, and P leaching in the sandy soil and may therefore be a useful tool for improvement of nutrient management in sandy soils.

Abstract Restoring wetlands on agricultural land can release soil P to surface waters. Phosphorus is a limiting nutrient in many freshwater systems, thus restricting its release will improve surface water quality. A P balance was used to examine how P was cycling in a Carolina Bay wetland eight years after restoration from prior-drained agricultural land. The change in soil P was evaluated between archived samples taken at restoration (2005), and eight years after restoration (2013). Measured P fluxes included atmospheric deposition, plant uptake, and loss to surface water outflow. The soil total P pool at the time of restoration was 810 kg P ha -1 . No significant (α=0.05) decrease in the soil P pool was observed. Atmospheric deposition contributed 7 kg P ha-1, plants accumulated 28 kg Pha-1 and incorporated 27 P ha-1 into woody biomass and 1 kg P ha-1 on the forest floor litter, and 1.7 kg P ha-1 was lost to surface waters draining the wetland. Because the loss of P to surface waters was small, and because runoff water concentrations of P declined through this period of study to concentrations below those likely to cause eutrophication (< 0.1 mg L-1), we concluded that the wetland was not contributing to the degradation of surface water quality of nearby streams following restoration. Further, relatively “isolated” wetlands such as that studied may be promising sites for future wetland mitigation projects due to limited impacts on surface water quality.

Phosphorus Losses

Balancing the weighting of various components of phosphorus loss in models is a critical but often overlooked step in accurate estimation of risk of P loss under field conditions. This study compared the P loss coefficients used to predict dissolved P losses from desorption from accumulated P in the soil, and those incidental to applications of P as fertilizer or manure, with extraction coefficients determined from actual P losses reported in literature for sites in Canada, with the addition of some sites with similar soils and climate from the northern tier of the United States. The extraction coefficients for dissolved P measured in runoff water was greater by a factor of 6.5X in year-round edge-of-field measurements than in runoff boxes, indicating that models using P extraction coefficients derived from runoff box experiments will be underestimating the magnitude of losses from P accumulation in soil. Differences among the measurement methods (runoff box, rainfall simulator or edge-of-field) were not evident for incidental losses from applied P, but current models appear to over-predict the losses of applied P. Good fit between measured and modelled DP concentrations were achieved by applying coefficients of 0.275 to the fertilizer equations, and 0.219 to the manure equations, implying that 72.5% of fertilizer P and 78% of manure P are not available for runoff. This study underlines the importance of considering the relative weights of the various components of P loss as new models are developed and validated.

We simulated P leaching on active dune (AD), semi-stabilized dune (SSD) and stabilized dune (SD) under 140, 700 and 1400 mm of rainfall in Horqin Sandy Land Inner Mongolia, China. The results showed that the available phosphorus (AP) pool decreased by 5–50% in topsoil (0–10 cm), and increased by -5–220% in subsoil (10–20 cm) in AD, SSD, and SD soil. The total P (TP) pool in topsoil (0–10 cm) decreased by 1.8–5.0%, and increased by -5–4.6% in subsoil (10–20 cm) in AD, SSD, and SD soil. The P loss in the soils (0-20 cm) was 0.5–4.5% in AD, SSD, and SD soil. These data indicated that significant downward movement of P occurred during soil leaching. And, the movement of soil P by leaching can cause P loss and changes in vertical distribution of P. Moreover, the difference in P concentration, drawn up by plant roots, between topsoil and subsoil can buffer the P loss at the start of leaching. Therefore, vegetation restoration is essential to reduce P loss in sandy lands.
