“…The results confirm an increase in the release of DRP and TP after the application of the biogas digestate and are in accordance with previous studies in which digestate from biogas production using household waste or crop residues (mixed with manure and/or sewage sludge) was applied (Sharpley and Moyer, 2000;Cherobim et al, 2017;Young et al, 2017). Long-term runoff analyses from an agricultural field site under organic fertilization (swine manure) showed increased P leaching and a severe impact from storm events (30-60 and >60 mm of precipitation; Tomer et al, 2016).…”

Core Ideas Severe rainfall events cause increased phosphorus release from soils. The proportion of DRP increases with increasing rainfall duration. Digestate application causes a 400‐fold increase in pore water P concentrations. The DRP fraction is clearly dominant immediately after fertilization. Digestate application facilitates a flux regime shift with preferential flow pathways. The application of fertilizers to soils may impair the quality of both surface and subsurface waters. Severe rainfall events that follow fertilizer application can increase P release from soils. In this study, suction plates were installed in a loamy soil with the aim of determining the P transport patterns and processes in the soil before and after the application of biogas digestate. Prior to the application of biogas digestate, the pore water concentrations of dissolved reactive P (DRP) were significantly lower than the total P (TP) concentrations, with DRP/TP ratios increasing from 0.03 to 0.89. After fertilizer application, the TP and DRP pore water concentrations increased 400‐fold. The DRP/TP ratio remained almost constant at 0.83. After 220 mm of precipitation, 4.5% of the P mass applied was leached to below the 50‐cm soil depth, indicating the general mobility of P in soils during high‐intensity rainfall. Brilliant Blue dye tracing experiments revealed that organic‐matter‐rich biogas digestate obviously changes the flow and transport patterns in soils from being homogenous to moderately heterogeneous, including preferential flow. Although the P loading across the flux plane had been equilibrated prior to treatment, after the application it was found to be concentrated in preferred transport regions. The emerging conclusion is that the risk of ground and subsequent surface water pollution with P after fertilization with biogas digestate originates not only from the applied P mass but also from the shift in the flow and transport regime caused by the organic‐matter‐rich slurry.

“…Most recently, their emissions have been investigated, and new solutions of efficient P removal are being developed (Cramer et al 2018 ). Mitigation strategies for controlling P export to rivers and coastal systems should include the regulation of water flows such as controlled drainage (Young et al 2017 ). Controlled drainage, a frequently discussed P-attenuation approach in lowland catchments, can lower the P load released to surface water bodies because of a reduction in water flux (Zhang et al 2017 ).…”

This special issue of Ambio compiles a series of contributions made at the 8th International Phosphorus Workshop (IPW8), held in September 2016 in Rostock, Germany. The introducing overview article summarizes major published scientific findings in the time period from IPW7 (2015) until recently, including presentations from IPW8. The P issue was subdivided into four themes along the logical sequence of P utilization in production, environmental, and societal systems: (1) Sufficiency and efficiency of P utilization, especially in animal husbandry and crop production; (2) P recycling: technologies and product applications; (3) P fluxes and cycling in the environment; and (4) P governance. The latter two themes had separate sessions for the first time in the International Phosphorus Workshops series; thus, this overview presents a scene-setting rather than an overview of the latest research for these themes. In summary, this paper details new findings in agricultural and environmental P research, which indicate reduced P inputs, improved management options, and provide translations into governance options for a more sustainable P use.

“…However, there is no definite conclusion concerning the relationship between the rainfall amount and the total N and P concentration in the runoff and adjacent stream water because of the complex processes of N and P transport [24]. To date, the relationship between the rainfall and nutrient runoff losses from agricultural fields is often explored by using monthly or bimonthly rainfall monitoring data [25][26][27][28]. We consider that this approach cannot accurately predict agricultural nutrients, such as N and P runoff over the rainfall amount.…”

Background: Rice paddy wetlands may serve as a nutrient source or sink in agricultural ecosystems. However, the pattern of nutrient loss on a watershed scale is not clear. A year-round on-site observation study based on 6-h intervals was conducted. Rainfall, temperature, runoff nutrient concentrations, and adjacent stream water samples were automatically monitored to uncover the temporal changes in the runoff losses of the predominant nutrient proxies (total N and total P) from a typical rice-planting area (120 ha) in the Yangtze river delta region of China. Results: A high total N concentration in the rice-planting area was observed during the rice-planting season; however, significant fluctuation in the total P was evident throughout the year. The Δtotal N (drainage minus stream) parameter showed negative values with a mean of −0.25 mg L −1 , while Δtotal P showed positive values with a mean of 0.06 mg L −1. The annual average N and P runoff from paddy field were 11.6 kg ha −1 and 1.5 kg ha −1 , respectively. The window phases for the total N loss were mainly concentrated in the rice-growing season. However, the window phase for the total P loss was more dispersive throughout the year. No apparent relationships were found between rainfall and N and P concentrations by self-organizing map analysis. Conclusions: The high-resolution monitoring, in this study, suggested that nutrient loss loading rather than nutrient concentration was strongly related to surface runoff Therefore, fertilization before high-intensity rainfall should be avoided to mitigate the nutrient runoff losses and maintain the rice wetland eco-function.
