“…The experiment was conducted in controlled growth conditions that included a day/night cycle of 16/8 h, with a day/night temperature of 25/19 • C and artificial lighting to complement daylight. Struvite (STR) used in the experiment was precipitated from a liquid fraction of anaerobic digested slurry (LFDS) obtained at a farm-scale bio-refinery located at the Experimental Dairy Farm 'De Marke' in Hengelo (Gld), the Netherlands (52 • 03" N, 6 • 18" E) (the scheme and description of the bio-refinery are presented in another authors' work [13]). The content of N, P and Mg in STR was 23.1, 39.4, 32.3 g kg −1 respectively.…”

This paper presents the results of a pot experiment aimed at the assessment of the fertilizer value of struvite, a precipitation product obtained from a liquid fraction of the digestate. The effects of struvite (STR), struvite + ammonium sulphate (STR + N) and ammonium phosphate (AP) treatments were examined on maize and grass cultivation on silty loam and loamy sand soil. The crop yields were found to depend on both the soil type and experimental treatment. Crop yields produced under STR and STR + N exceeded those under the control treatments by respectively 66% and 108% for maize, and 94% and 110% for grass. Crop yields under STR + N were similar or greater than those under the AP treatment. The nitrogen recovery by maize and grass reached respectively 68% and 62% from the struvite and 78% and 52% from AP. The phosphorus recovery by maize and grass reached 7.3% and 4.8%, respectively, from struvite (i.e., STR and STR + N), which was lower than that from the AP (18.4% by maize and 8.1% by grass).

This paper presents the results of a pot experiment aimed at the assessment of the agronomic and economic effectiveness of ammonium sulphate from an agro bio-refinery (Bio-AS). The Bio-AS was obtained by means of the ammonia stripping process from effluent after struvite precipitation from a liquid fraction of digestate. The agronomic effectiveness of Bio-AS in a pot experiment with maize and grass in two different soils, silty loam (SL) and loamy sand (LS), was investigated. The fertilising effect of Bio-AS was compared to commercial ammonium sulphate fertilizer (Com-AS) and control treatment (without fertilisation). The crop yields were found to depend on both soil type and nitrogen treatment. Crop yields produced under Bio-AS and Com-AS exceeded those under control treatments, respectively for SL and LS soils, by 88% and 125% for maize and 73% and 94% for grass. Crop yields under Bio-AS were similar to those under the Com-AS treatment. The fertilizer use of Bio-AS affected the chemical composition of plants and soil properties similarly as Com-AS. This suggests that Bio-AS from a bio-refinery can replace industrial ammonium sulphate, resulting in both economic and environmental benefits.Energies 2019, 12, 4721 2 of 15 ammonia (NH 3 ), nitrous oxide (N 2 O), and hydrogen sulphide (H 2 S) to the atmosphere [8,9]. Due to intensification of animal production observed in EU agriculture, the European Commission regulated the use of organic fertilizers in the Nitrates Directive adopted on 12 December 1991. It aimed at water quality protection across Europe by prevention of pollution of the ground and surface waters with nitrates from agricultural sources and by promoting the use of good farming practices. One of the major restrictions was the limitation of the amount of nitrogen applied, taking into account the crop needs, all nitrogen inputs and soil nitrogen supply, as well as the maximum amount of livestock manure to be applied (corresponding to 170 kg nitrogen per hectare per year) [10]. The Dutch government negotiated special derogation allowing use of 250 kg·N·ha −1 in organic fertilizers under the condition of more efficient use of nitrogen from animal sources, which is included in the Dutch Manure Policy [11] and also encompasses regulations limiting the use of P from organic fertilizers. Many studies report considerable farm-gate N surplus for dairy farms per unit area, for example 138 kg N ha −1 year −1 in Sweden, 223 kg·N·ha −1 ·year −1 in the Netherlands, and 240 kg·N·ha −1 ·year −1 in Denmark [12]. So far, the dominant method of processing of animal waste has been anaerobic digestion. The process results in the production of biogas and digestate [13]. Biological conversion of organic compounds during anaerobic digestion considerably reduces the odour as compared to untreated manures [14][15][16]. Both the nitrogen and phosphorus content in the digestate are comparable with untreated manure; however, in contrast to livestock manures, the digestate is characterized by the presence of the nutrients in solub...

“…Until now, in order to ensure high yields of biomass, rational mineral fertilization has generally been used. Attention is increasingly drawn to the recovery of macroelements from organic and mineral waste (Kiciñska and Gruszecka-Kosowska 2016, Nahm and Morhart 2018, Szymañska et al 2019. Thanks to this assumption, we can limit the use of mineral fertilizers in the context of retardation of natural resources.…”

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.
