The need to find and maximize the use of alternative sources of nutrients for plants and soil environment have been on the forefront of research in sustainable agriculture. These alternatives have to be affordable, accessible, reproduceable, and efficient to compete with established inorganic fertilizers while at the same time reduce any potential negative impacts on the environment. We aimed to evaluate the effectiveness of digestate fertilization in an agricultural system over a period of three years. The digestate utilized in the study consisted of animal waste-based digestates, namely pig manure digestate, chicken manure digestate, and cow manure digestate, and were compared with synthetic nitrogen fertilizer. Every year, the digestate and the synthetic nitrogen fertilizer were split applied at the rate of 90 and 80 kg N ha−1. The soil chemical composition after three years of fertilization showed a slight decrease, significantly different nitrogen and carbon changes while phosphorus and potassium were significantly higher in the digestate treatments. The third year of digestate application showed higher grain yield than previous years and the yield from the digestate treatments were significantly different from the synthetic nitrogen fertilizer. The nitrogen use efficiency for the three years was in the range of 20–25 percent in the digestate treatments, with a strong correlation between the nitrogen use efficiency and the grain yield. There were varied results in the grain quality and straw quality in the digestate and synthetic nitrogen fertilizer with no clear trend observed. Our results showed a relatively high potential of animal waste digestates over the short to mid-term use with a positive result obtained in comparison to synthetic nitrogen fertilizer under favorable climatic conditions.

The increasing quantities of organic residues are becoming one of the most important problems for climate change mitigation. Sustainable utilization technologies are required to minimize the effect of recycling on the environment. Nevertheless, treated residues should be part of the circular bioeconomy. One of the most promising processes is the biogas system, with the final products biogas and digestate, which contain valuable nutrients and are therefore suitable as agricultural fertilizers. However, there is lack of research data on the effectiveness of digestate on environmental factors including soil quality as well as crop productivity and quality. In this study, we compare the roles of different digestates (chicken manure digestate, cow manure digestate, and pig manure digestate) on spring wheat productivity, soil microbial activities, and greenhouse gas emissions in loam and sandy loam soil under controlled climate conditions. The liquid digestate applied was equivalent to 170 kg N ha−1 of total N presented. Overall, results showed that the two soil types responded differently to the addition of the digestates, and the benefits depended on soil characteristics as well as on the type of the digestate applied. There was a higher effect on soil microbial activity in sandy loam soil compared to that of loam soil. Chicken manure digestate had the highest value of dehydrogenase activity and soil microbial biomass C of 9.23 µg TPFg−1 h−1 and 175.6 µg g−1 across the two soil types. CO2 and N2O emissions were moderately higher in loam soil when compared to that of sandy loam soil. The highest CO2 peak emission at 0.0107 µg ha−1 h−1 occurred in pig manure digestate in the sandy loam soil, and regular peak patterns observed in loam soil fertilized with pig digestate manure. Chicken manure digestate had the highest peak emissions across both soil types at 0.007950 mg ha−1 h−1 and 0.5667 mg ha−1 h−1 in the loam and sandy loam soil, respectively. The biomass yield varied across the soil types irrespective of the digestate applied. The agricultural benefits of digestates in different receiving soil ecosystems supplying essential nutrients for crop productivity, coupled with its environmental benefits, makes it an encouraging prospect in temperate climate zones.

The exercise of biochar in agribusiness has increased proportionally in recent years. It has been indicated that biochar application could strengthen soil fertility benefits, such as improvement in soil microbial activity, abatement of bulk density, amelioration of nutrient and water-holding capacity and immutability of soil organic matter. Additionally, biochar amendment could also improve nutrient availability such as phosphorus and nitrogen in different types of soil. Most interestingly, the locally available wastes are pyrolyzed to biochar to improve the relationship among plants, soil and the environment. This can also be of higher importance to small-scale farming, and the biochar produced can be utilized in farms for the improvement of crop productivity. Thus, biochar could be a potential amendment to a soil that could help in achieving sustainable agriculture and environment. However, before mainstream formulation and renowned biochar use, several challenges must be taken into consideration, as the beneficial impacts and potential use of biochar seem highly appealing. This review is based on confined knowledge taken from different field-, laboratory- and greenhouse-based studies. It is well known that the properties of biochar vary with feedstock, pyrolysis temperature (300, 350, 400, 500, and 600 °C) and methodology of preparation. It is of high concern to further investigate the negative consequences: hydrophobicity; large scale application in farmland; production cost, primarily energy demand; and environmental threat, as well as affordability of feedstock. Nonetheless, the current literature reflects that biochar could be a significant amendment to the agroecosystem in order to tackle the challenges and threats observed in sustainable agriculture (crop production and soil fertility) and the environment (reducing greenhouse gas emission).

Background Climate mitigation is a major consideration when choosing bioenergy systems. Anaerobic digestion of biomass is a bioenergy system, which is normally used for the treatment of manure or other residues, but cultivated energy crops may also provide a potential feedstock. One of the main crops for biogas production is still maize, but it may be desirable to replace it by perennial grasses, which also have high yields, but do not require as much management. The aim of this study was to analyse greenhouse gas (GHG) emissions in a biogas production system based on a perennial grass, cocksfoot, grown under different fertiliser application systems. Methods Field and laboratory experiments were carried out over a 7-year period to evaluate the influence of mineral nitrogen and digestate fertiliser application on cocksfoot biomass and biogas productivity. The obtained data were used to calculate GHG emissions and emission savings for the whole biogas production cycle, by use of the SimaPro v.8 software with the IMPACT 2002+ model, based on the climate change environmental impact category. Results Productivity of cocksfoot (Dactylis glomerata L.) was influenced by the annual rate of nitrogen applied as fertiliser, the fertiliser type and year, as influenced by the weather conditions. The biomass yield of cocksfoot fertilised with 180 kg nitrogen ha−1 year−1 was similar regardless if the nitrogen was applied as digestate or mineral fertiliser. At higher rates of nitrogen application (360–450 kg ha−1 year−1), higher yields and lower net GHG emissions could be obtained from the biogas production cycle when the nitrogen was applied as digestate compared to mineral fertiliser, especially in dry years. Energy input over the whole cycle was mainly influenced by the type of fertiliser and the biomass yield. Mineral fertiliser generally caused higher levels of GHG emissions than organic digestate fertiliser, when the same amount of energy is produced. Conclusions The cocksfoot grass-based biogas production system showed that a significant GHG emission saving potential exists, if nitrogen is added as digestate instead of mineral fertiliser, for similar yields of biomass and energy from biogas. Cocksfoot grass fertilised with digestate is thus a promising feedstock for biogas production.

Global climate change concomitant necessitates search for alternative and renewable energy generation systems as they reduce the greenhouse gas emissions. In warm climate, the productivity and the profitability of the perennial crops are high while in northern European countries the biomass DM yields are significantly lower. The aim of this study is to identify the potential crops from Artemisia dubia, Miscanthus giganteus, Sida Hermaphrodita for bioenergy, evaluate the biomass quality and energy potential in comparison with the traditional Festuca arundinacea grass, cultivated under the northern European-Lithuanian-weather conditions. Crops were grown with the applied 90 or 170 kg ha−1 of mineral nitrogen fertilizer. The biomass quality varied significantly with the grass species and fertilization rate. The productivity of crops varied between the species and the highest of 21.54 t of DM ha−1 was obtained from Miscanthus giganteus fertilized with 170 kg N ha−1. Most of the models available in the literature suggest that these crops are not economically feasible in Northern part of temperate climate zone due to the short vegetation season and very cold winters. However, the results obtained here suggest that under constantly changing climate conditions Miscanthus giganteus, may be promising feedstock for renewable energy.

In the world, fossil fuel resources are constantly decreasing and increasing energy use. This leads to wider use of biomass in various industrial areas. Also, for the production of heat and electricity. Depending on the situation of current market, much attention is being paid to increasing the potential of biomass and to ensure the needs of users. Recently, much attention is paid to non-food energy plants, which could be used in thermochemical conversion technologies. These plants must be well adapted to climatic conditions, to grow a high biomass yield, to possess high energy value, easy to use for biofuel production and low environmental impact. Having a high energy potential and promising plants for cultivation in a changing climate conditions can be characterized and these plants: this is Miscantus spp. (namely miscanthus), Artemisia dubia Wall. (mugwort) and Cannabis sativa L. (fiber hemp). The article summarizes long-standing biometric and thermal performance results on Miscantus spp. (namely miscanthus), Artemisia dubia Wall. (mugwort) and Cannabis sativa L. (fiber hemp). In Lithuania climate condition, it is possible to grow from 3.26 to 17.06 t ha-1 of dry biomass per year from the mentioned plants. The calorific value of biomass has a huge influence on assessment of energy potential from plants. After combustion of 1 kilogram of Miscantus spp., Artemisia dubia Wall. and Cannabis sativa L. biomass it stands out on average 18.3±0.06, 18.5±0.66 and 17.43±0.06 MJ of heat, respectively. An equally important property which assesses the suitability of biomass for biofuels is ash content. The average ash content of biomass from Miscantus spp. and Artemisia dubia Wall was 1.51±0.03 % and 2.69±0.33 %, i.e. 2.22 times and 1.25 times lower than Cannabis sativa L.

Security of energy supply, promotion of the bio-economy, nutrient recycling, and innovation are prioritized policy areas in the EU Strategy for the Baltic Sea Region (EUBSR). The Baltic Sea Region (BSR) has a great bioenergy potential worth exploring in this context. This paper explores the state-of-art of bioenergy systems and synergies with eco-systems services in the BSR region in the context of developing the region’s bio-economy. In this brief assessment, we consider 8 countries (i.e. Sweden, Finland, Estonia, Latvia, Lithuania, Poland, Denmark, and Belarus) in the region. While the production and use of modern bioenergy can help reduce greenhouse gas (GHG) emissions, promote energy security, diversify energy resources, and contribute to a successful circular economy and rural development, it is important to find a balance between the exploration of resources and the management of eco-systems services. In addition, both climate change vulnerability and bioenergy production may affect the environment and the capacity of the BSR to deliver ecosystem services (ESS). We recommend integrated strategies for optimal use of bioresources in the region. Bioeconomy can be realized by innovative approaches, establishing cross-cutting institutional and policy linkages for increased prosperity and green growth in the Baltic Sea Region

Purpose: The current study was aimed to analyse the occurrence of water and nitrogen stress in spring barley and estimate their effects on the crop performance under low-input and conventional management. Materials and methods: Field experiments were conducted during 2007–2009 at the Institute of Agriculture, Lithuanian Research Centre for Agriculture and Forestry on a sandy-loam soil. The management systems were: (a) conventional, with the application of fertilizers and pesticides adjusted to target 5 t ha−1 grain yield; and (b) low-input, without fertilizers and pesticides. Biomass and nitrogen concentration, leaf area index, soil moisture, drainage water runoff and ground water table were measured periodically during the growing season. Results: In all three experimental years, the annual precipitation was close or above the climate normal, but a large part of the rainfall (up to 310 mm) was lost through drainage contributing to the occurrence of temporary moisture deficit in late spring or summer. Water stress resulted in a lower spring barley biomass accumulation rate and lower biomass yield in the years characterized by sub-optimal rainfall distribution. Direct measurements of water retention in the soil and DSSAT model simulations gave relatively good indication of water stress occurrence. Under the low-input management, nitrogen nutrition level was a major constraint for spring barley biomass and grain yield formation. Conclusions: Under Central Lithuania’s conditions, spring barley frequently experiences temporary water stress, because a relatively high proportion of annual precipitation is lost during the non-growing period. This crop can benefit from anticipated increased precipitation and carbon dioxide levels if adequately provided with nitrogen.

Anaerobic digestion of biomass produces biogas for combustion and also provides a residual digestate. Although sometimes regarded as a waste product, the nutrient-rich chemical composition of digestate makes it a potential organic fertilizer for agriculture. The goal of this study was to evaluate the effectiveness of digestate as a fertilizer on the biomass yield and chemical composition of cocksfoot (Dactylis glomerata L.). In a 5-year small-plot field experiment digestate fertilization treatments supplying 90, 180, 270, 360 and 450 kg N ha−1 were compared with untreated plots and plots fertilized with 180 kg N ha−1 of mineral N fertilizer. Swards fertilized with digestate produced higher biomass yield compared with the control. The same rate of nitrogen fertilizer (180 kg N ha−1) supplied as digestate and from mineral fertilizers gave similar results on biomass yield. Herbage in swards fertilized with digestate contained less nitrogen, but the C:N ratio was much more suitable for biogas production. Digestate fertilization resulted in higher concentrations of cellulose and hemicellulose in biomass and lower contents of the inhibitors of anaerobic digestion—sulphur, calcium, magnesium and phosphorus—compared with those of swards receiving mineral fertilizers.

Tyrimų tikslas – palyginti mineralinių ir organinių (biodujų gamybos atliekos – BIODga) trąšų, naudotų skirtingomis normomis, poveikį dirvožemio suminės ir labiliosios anglies kiekio pokyčiams. Tyrimų objektas – dirvožemis, giliau glėjiškas karbonatingasis išplautžemis (Endohypogleyi-Calc(ar)ic Luvisols), kuriame auginta ‘Amba’ veislės paprastoji šunažolė (Dactylis glomerata L.). Laboratoriniai tyrimai atlikti 2013–2015 m. LAMMC Žemdirbystės instituto Cheminių tyrimų laboratorijoje. Eksperimento metu nustatyta, kad tręšiant mineralinėmis trąšomis dirvožemio organinės anglies kiekis buvo mažesnis, palyginti su netręštu. Suminės dirvožemio organinės anglies (Corg.) kaupimasis priklausė nuo BIODga normos, o didžiausias dirvožemio organinės anglies kiekis buvo tręšiant maksimalia azoto (N450) norma. Tyrimai parodė tręšimo įtaką labiliosios vandenyje tirpios anglies (C) kiekiui dirvožemyje (0–30 cm sluoksnis). Tręšimas azoto trąšomis tiek mineralinėmis, tiek biodujų gamybos atliekomis lėmė santykinai didesnį labiliosios C kaupimąsi viršutiniame (0–10 cm) dirvožemio sluoksnyje negu suminės organinės anglies (Corg.).

Grass biomass is a suitable feedstock for biogas production; however, this type of biomass in countries with a colder climate is too low. More research findings on the species of grasses and growing technologies will likely reveal the compatibility and interactions in an effort to ensure the required high-quality yield and the greatest potential for energy over the years to contribute to the development of biomass use. This study presents the results of experiments conducted on Endocalcari-Epihypogleyic Cambisol (CMg-p-wcan) to evaluate the biomass yield, quality and bioenergy potential of perennial grasses. Three perennial grasses—tall fescue (Festuca arundinacea Schreb.), cocksfoot (Dactylis glomerata L.) and reed canary grass (Phalaris arundinacea L.)—were selected for biogas production. Different growing technologies were used to evaluate the influence of fertilisation (N90 and N180) and the cutting frequency (two and three cuts per growing season) on the biomass productivity and energy potential. The results of a two-year experiment suggest that the biomass yield and energy potential depend on grass species and growing technology. The highest biomass yield and energy potential was achieved for tall fescue harvested twice per season and for the first time at the flowering stage.

Biomass has variable composition and properties which depend on fertilization intensity. Reed canary grass (Phalaris arundinacea L.) was investigated in small-plots experiment on light soil Arenosols. The biomass yield data on the average of two years of sward use showed that in this experiment biomass yield of reed canary grass without nitrogen was significantly lower than that fertilized with nitrogen, and ash content range depended on fertilization. In comparison with grass fertilized with N120 and N0 the biomass with nitrogen fertilization N120 showed the lowest concentration of ash, which is a favourable feature for combustion process. Further research into the management of reed canary grass is needed.
