“…Samples from all treatments were subjected to the same staining procedure, and the roots were thoroughly rinsed to remove the stain after digitization. The average root N concentration across treatments (15.7 g kg −1 DM), for which the effect of soaking solutions was nonsignificant ( p > .05), was very close to previously reported values for unstained timothy roots at first cut (13.5 g N kg −1 DM in growth chambers [Bertrand et al., 2014] and 15.7 g N kg −1 DM in a field experiment [Berglund et al., 2018]). A previous study also reported that fine root N concentration was unaffected by root preparation methods (roots rinsed in tap water, deionized water, or prepared dry, immediately after sampling) (Rytter & Rytter, 2010).…”

Root recovery and elemental composition in a perennial grass as affected by soaking conditions

Roots of perennial grasses, with their fibrous architecture, are difficult to separate from the surrounding soil. We assessed the effect of five soaking solutions (sodium bicarbonate, sodium chloride, disodium ethylenediamine tetraacetic acid [disodium EDTA], distilled water, and sodium hexametaphosphate) and three soaking durations (15 min, 2 h, and 16 h) on root recovery and root elemental composition, with and without a mathematical correction for residual soil adhering to roots. Roots were collected by soil coring in a timothy (Phleum pratense L.) sward on a loam soil. After soaking, roots were washed, digitized, and analyzed for elemental composition. Soaking duration did not affect root mass and length, but the 16-h duration resulted in the lowest ash concentration (136.7 vs. 146.4 g kg -1 dry matter [DM] on average across shorter durations), indicating a lower contamination by soil. The greatest root recovery was obtained with sodium bicarbonate (0.118 vs. 0.101 g DM core -1 on average across other solutions). Sodium hexametaphosphate led to the lowest root ash and element concentrations but left a P residue on the roots. Distilled water did not impair root cell integrity and led to a similar root recovery as sodium chloride, disodium EDTA, and sodium hexametaphosphate. A mathematical correction improved the estimates of (a) root mass for all soaking solutions and (b) root elemental composition for elements with higher concentrations in soils than in roots. Soaking solutions should be chosen as a function of the study objectives because of the trade-off between root recovery and contamination by adhering soil.

“…Those tendencies are in line with the general understanding of N 2 O emergence in soils, where soil moisture is a major driver of N 2 O emissions [33,94]. Concerning the order of magnitude of the N2O emission fluxes from the non-inundated shore of the littoral zone, their overall level is not higher than on nutrient-rich temperate extracted fens after inundation [41] or from a cultivated fen peat [95]. All fluxes from the open water were below detection limit.…”

Rewetted extracted peatlands are sensitive ecosystems and they can act as greenhouse gas (GHG) sinks or sources due to changes in hydrology, vegetation, and weather conditions. However, studies on GHG emissions from extracted peatlands after rewetting are limited. Methane (CH4) and nitrous oxide (N2O) emission fluxes were determined using the opaque closed chamber method along water level gradients from littoral zones to the open water body of constructed shallow lakes with different vegetation zones in a nutrient-rich rewetted extracted peatland in Sweden. Vegetation communities and their position relative to water level, together with short-term water level fluctuations, such as inundation events and seasonal droughts, and temperature had a significant impact on CH4 emissions fluxes. During “normal” and “dry” conditions and high soil temperatures, CH4 emissions were highest from Carex spp.-Typha latifolia L. communities. During inundation events with water levels > 30 cm, sites with flooded Graminoids-Scirpus spp.-Carex spp. emitted most CH4. Methane emissions from the water body of the constructed shallow lakes were low during all water level conditions and over the temperature ranges observed. Nitrous oxide emissions contributed little to the emission fluxes from the soil-plant-water systems to the atmosphere, and they were only detectable from the sites with Graminoids. In terms of management, the construction of shallow lakes showed great potential for lowering GHG emission fluxes from nutrient rich peatlands after peat extraction, even though the vegetated shore emitted some N2O and CH4.

“…Our research revealed that the lower the dose of sewage sludge, the lower the uptake of macronutrients with the yield of reed canary grass and giant miscanthus biomass. The lower amount of macronutrients uptaken results from the amount of yield and the 'dilution effect' of these nutrients in the plant biomass, which finds confirmation in other studies (Antonkiewicz et al 2018, Berglund et al 2019, Biel et al 2017. The study by Berglund et al (2019) also confirms that reed canary grass utilizes macronutrients well and, compared to other species of grasses, it takes up more of them with the yield compared to the amounts introduced with fertilizers.…”

Energy crops, on account of high biomass yields, have high nutrient requirements in relation to macroelements. Municipal sewage sludge can be a potential source of micronutrients for plants with high nutrient requirements. The use of macronutrients from sewage sludge by energy crops is an alternative form of nutrient recycling from organic waste. The aim of the research was to assess the content, uptake and use of N, P, K, Ca, Mg and Na from municipal sewage sludge by reed canary grass (Phalaris arundinacea L.) and giant miscanthus (Miscanthus × giganteus Greef et Deu). The effect of sewage sludge on the ratios between macroelements in the biomass of the tested plants was also assessed. The multi-year field experiment involved four levels of fertilization with sewage sludge at doses of 0, 10, 20, 40, 60 Mg DM·ha−1. Due to the low potassium content in this waste, supplementary potassium fertilization (100 kg K·ha−1 in the form of 40% potassium salt (KCl)) was applied once on all plots. It was established that the increasing doses of sewage sludge had a considerable effect on the increase in the content and uptake of N, P, K, Ca, Mg and Na by the biomass of the tested energy crops. The research shows that, compared to giant miscanthus, reed canary grass had a higher macronutrient content. The largest amount of uptaken N, P, K, Ca and Mg was found in reed canary grass (at a dose of 40 Mg DM·ha−1), whereas Na was detected in giant miscanthus (at a dose o 20 Mg DM·ha−1). It was established that giant miscanthus, on account of its higher yielding, recovers macroelements from sewage sludge applied to soil at a dose of 10 Mg DM·ha−1 to the greatest extent. The increasing doses of sewage sludge considerably decreased the value of K:Mg, Ca:Mg, Ca:P ratios in miscanthus biomass yield. The applied doses of sewage sludge (40–60 Mg DM·ha−1) increased the value of K:Ca, Ca:P, K:Na ratios in miscanthus biomass yield.
