“…Marron () reviewed different organic amendment treatments for three SRC crops, including willow, and found overall a mostly positive effect of organic amendments on growth, with sewage sludge having the greatest positive effect, followed by manure. The application of wastewater or manure to SRC plantations has been advocated for some time as a way to deal with waste products with high nutrient contents (Aronsson & Perttu, ; Kuzovkina & Quigley, ; Guidi Nissim et al ., ). Organic amendments may potentially act as a slow‐release source of N (Adegbidi & Briggs, ; Adegbidi et al ., ), which would be more advantageous in a commercial setting where plant growth in subsequent years after cutback would most likely preclude the use of machinery for application.…”

Sustained interest in producing renewable energy from dedicated woody biomass crops, such as shrub willow (Salix spp.), through short rotation coppice (SRC) has resulted in a substantial amount of published research on SRC over the past few decades. One area of constant focus has been the nutritional requirements for optimal growth and yield. Inconsistency in the results of individual research trials has likely been a driver of repeated experimentation. This review is intended to provide a quantitative examination of the effect of fertilization treatments on willow biomass yield in field conditions. Data from the literature were collected and summarized to test for significant sources of variation in willow biomass nitrogen (N) pools of common SRC genotypes used in North American and European research programs. A meta-analysis was conducted on studies comparing synthetic or organic sources of N willow fertilization to an unfertilized control treatment to test for yield response. Overall, the majority of responses to fertilization were positive, although variation by species, N source material, and crop age were found. While no clear pattern in N dosage response was observed, the level of yield response was correlated with geographic and climatic variables. Nitrogen export levels were fairly predictable, and the synthesis presented here can be used to refine current guidelines. Environmental and economic aspects are also considered.

“…These characteristics include their non-edibility, their high nitrogen absorption capacity as well as their ability to absorb certain metals such as cadmium (Aronsson and Perttu, 2001). Willows have been used for a multitude of environmental applications, such as municipal effluent treatment (Dimitriou and Aronsson, 2011;Guidi Nissim et al, 2015;Hasselgren, 1998;Holm and Heinsoo, 2013;Larsson et al, 2003;Perttu and Kowalik, 1997), biosolids treatment (Dimitriou and Aronsson, 2004), landfill leachate treatment (Aronsson et al, 2010;Dimitriou and Aronsson, 2010), polluted groundwater (Guidi Nissim et al, 2014) and effluent total evapotranspiration Gill, 2014, 2016;Frédette et al, 2019;Gregersen and Brix, 2001) for more than twenty years. In recent years, it has also been shown that the use of willow beds has an interesting potential for the treatment of wastewater (Grebenschykova et al, 2017, Khurelbaatar et al, 2017, complete evapotranspiration of effluent (Frédette et al, 2019) and nutrient recovery (Rastas Amofah et al, 2012) in cold climate.…”

The objective of this study was to evaluate the treatment efficiency of a short rotation willow coppice (SRWC) vegetation filter for the treatment of wastewater from a municipal primary effluent in a humid continental climate context. The experimental work was carried out at pilot scale on a willow plantation located in Québec, Canada. The experimental design included nine plots that were irrigated with groundwater (L0 = 14 mm/d) or two primary effluents (L1 = 10 and L2 = 16 mm/d) for 111 days. This research showed that SRWCs operated on coarse-textured soils allow efficient removal of organic matter (91 % of COD for L1 and L2) and nitrogen (98 % of TKN for L1 and L2) from wastewater. It was also shown, in this case, that the total nitrogen loading should be used as the limiting design parameter to minimize the risk of contaminating underground drinking water sources with nitrates. Almost complete removal of total phosphorus was observed during this experiment (98 % for L1 and L2). However, a significant increase in soil available phosphorus was observed following the L2 treatment, which suggests an eventual phosphorus soil profile saturation in the event of continued wastewater irrigation. Avoiding such a saturation would require chemical phosphorus removal upstream of SRWC vegetation filters. Finally, an imbalance between irrigation and willows needs was observed as a result of irrigating plots at a constant hydraulic loading rate. Thus, irrigation of an SRWC with wastewater should be modulated according to willow seasonal transpiration trends to allow a better allocation of water and nutrients according to plant needs, and in doing so, increase treatment efficiency and resources valorization. Highlights • Efficient removal of OM and nitrogen (TKN) by coarse textured SRWC vegetation filter • TN should be used as the limiting design parameter of SRWC vegetation filter • Eventual P soil profile saturation in the event of continued wastewater irrigation • Irrigation should be modulated according to willow seasonal transpiration trends

“…Dewatering and stabilization of the FPLS therefore has the potential to be an effective strategy to minimize nutrient losses to the environment. In many countries, reed beds systems and willow plantations are widely used to dewater and stabilize slurries and improve its organic matter quality (Curneen and Gill, ; Peruzzi et al ., ; Guidi Nissim et al ., ). While these techniques have their benefits, application by mixing with irrigation water or directly to pastures with a boom sprayer is more likely in SIDS of the Caribbean.…”

This small-plot field study evaluated food processing liquid slurry (FPLS) as a potential fertilizer for tanner grass (Brachiaria arrecta) production on an acidic loam soil. The treatments, arranged in a randomized complete block design with three replicates, consisted of an unfertilized control, inorganic fertilizer applied at 50 and 200 kg nitrogen (N) ha À1 with and without phosphorus (P) at 50 kg P ha À1 , and FPLS applied at 50 and 200 kg N ha À1 . Compared to the unfertilized control, the FPLS applied at 200 kg N ha À1 significantly increased grass dry-matter yield (DMY), herbage crude protein (CP) and P content, and N and P uptake in the second of two trials and P uptake in both trials. However, DMY and contents, of CP and P were generally lower for the FPLS treatments compared to the inorganic fertilizers. Apparent N recovery was higher for the inorganic fertilizer treatments than FPLS treatments in trial 1, while apparent P recovery was similar among all treatments in both trials. The FPLS treatments did not significantly increase soil NO 3 -N and P concentrations, but increased NH 4 -N in the 0-15 cm layer. The results suggest that application of FPLS to tanner grass pastures is an alternative to its disposal in landfill.
