“…Clearly, the results in the present research were consistent with the published papers. On one hand, organic materials contain a large amount of lignin, which protects the soil carbon source and prolongs the existence of carbon in the soil [34]. On the other hand, long-term application of nitrogen fertilizer changed the activities of cellulose-and lignin-degrading enzymes, delayed the decomposition [35], and formed more stubborn lignin-like compounds [36].…”

“…A higher SR in NSS practices represented a lower application of mineral nitrogen fertilizer, which tended to lead to mineralization and the loss of soil organic matter [51,52]. Ammonium nitrate and urea-containing fertilizer significantly accelerated the release of total C from decayed organic matter, while organic fertilizer slowed the release of total C from decayed organic matter [34]. That was one reason illustrating that the high-SR caused high SOC accumulation and CMIs.…”

In China, excessive nitrogen fertilizer application in sweet maize fields contributes to greenhouse gas emissions. This study used maize straw (MS), cow dung (CD), biogas residue (BR), and straw-based biochar (CB) to substitute the mineral nitrogen fertilizer at 20% and 50% ratios in the Pearl River Delta in China. In comparison with a conventional amount of mineral nitrogen fertilizer (CK), the soil organic carbon (SOC) storages of the different treatments increased by 6.5–183.0%. The CB treatment significantly improved the inert organic carbon pool in the soil, while other types of organic materials promoted the formation of activated carbon pools. The treatments increased the soil carbon pool management index by 21.1–111.0% compared to the CK. Moreover, the CB treatments increased the soil carbon sequestration index by 78.3% and 155.8% compared to the CK. In general, substituting the mineral N fertilizer with BR, CB, and CD could improve the SOC accumulation in sweet maize farmland in South China. The CB at the high substitution level was the best measure for stabilizing carbon sequestration in the sweet maize cropping system. This experiment provides valuable information for ensuring the clean production of sweet maize in a typical subtropical area in East Asia.

“…The use of agrochemicals to enhance crop yield endangers biodiversity and ecosystems (Malaj et al, 2020). Reduced fertilizer usage by replacing it with biofertilizers (Klaic et al, 2021;Tsachidou et al, 2021), ensuring a sustained release of nutrients using amendments such as biochar (Ullah et al, 2020) and nanoparticles (Avellan et al, 2021), soil organic carbon sequestration (Abera et al, 2021;Brombin et al, 2020;Mancinelli et al, 2020), crop rotation (Hirzel et al, 2021;Shrestha et al, 2020), intercropping (Shah et al, 2021), adoption of agroecological practices (Abbasi Surki et al, 2021;Rakotovao et al, 2021), utilization of crop residues for maintaining soil fertility (Berazneva et al, 2018; are important for ensuring socio-ecological sustainability.…”

With the need to fulfil the rising food demands of the increasing population, the agriculture sector faces a huge challenge. The issue is compounded by climatic change, severe shortage of water, increasing salinity, habitat vulnerability and pollution amongst others. Considerable emphasis worldwide is focused on research aimed to sustain as well increase agricultural productivity. The present study focuses on systematically mapping the thrust areas of research related to sustainable agriculture based on search results from SCOPUS database. The retrieved data was analysed using VOS viewer application program to create network maps based on term co-occurrence analysis. The analysis further provides insight into the most active authors, countries, institutions as well as citations. A total of 12,261 documents were retrieved. A significant increase in the number of publications was seen in the last decade. The retrieved documents were contributed by authors belonging to 156 countries and had an average of 6.24 citations per document with an h-index of 40. Cluster analysis highlighted three focus areas of research- (1) sustainable agriculture (2) factors affecting crop yield and (3) basic research into plant growth, metabolism, development and aging. The underlying principle of all the research programs pertain to the use of innovative technologies and judicious use of resources for maximal production with due importance to environmental, economic and social aspects.

“…Regarding environmental and climate protection, the farmers are motivated to cultivate meadows to use the grass cut as substrate for AD-plants (Noll et al 2020). As further aspect, the conversion of untreated horse manure to biogas and utilisation of the digestate as fertilizer reduced the negative impacts to water bodies by nitrogen and sulphur compounds (Tsachidou et al 2021). In order to reach the national goals and to expand the utilization of difficult dry substrates across Germany, the FeBio project wants to develop a possible solution with the help of an innovative small-scale dry AD plant.…”

FeBio: R&D of novel 75 kWel AD plant for difficult agricultural residues: horse manure, straw and green waste

Substrates for biogas production will be provided mainly by residues in future. Without a complex and expensive pre-treatment, solid residues with dry matter (DM) content higher than 30%, e.g. horse manure, husk, grass or straw can only be used in small quantities in a wet anaerobic digestion (AD) plant to maintain a DM content of lower than 15%. Especially for small quantities of dry and solid residues, typical for rural and agricultural areas, the application of small-scale dry AD-plants with a maximum capacity of 75 kWel can be a technical smart solution. For solid residues, the dry AD process in combination with a Combined Heat and Power Plant (CHP)is technically favourable, as it works with DM content higher than 20% and provides electricity. The objective of the „FeBio“project (running time are 4 years, from 2020 – 2023 and funded by the German Ministry for Economic Affairs and Energy (BMWi) within the 7th Energy Research Programme) is the development of a small-scale dry AD plant for solid and stackable residues with low investment costs of 4,000 - 6,000 €/kWel and electricity generation costs of lower than 18 €-Cents/kWhel.
