Summary: Indigenous soil microbial biomass (ISMB) is crucial for maintaining soil health and biodiversity. This study compared the response of ISMB to biogas residue and chemical fertilizers using Mi-Seq sequencing and network analyses. The results showed that crop production was influenced by ISMB levels and fertilizer application strategy. Biogas residue resulted in higher production and stronger microbial links compared to chemical fertilizer. The study also found that biogas residue increased microbial diversity and reduced fungal pathogens compared to chemical fertilizer. This research provides important data for understanding the impact of ISMB and biogas residue on soil ecosystems.

Summary: The increasing global energy requirements and the negative impact of climate change have led researchers to focus on developing cleaner technologies for energy production. Microbial fuel cell (MFC) is an emerging method for generating clean energy. However, the burning of agricultural wastes by farmers in India and other East-Asian nations has caused significant air pollution. Innovative research on MFCs using post-harvest agricultural residue as a feed source could contribute to a cleaner and more sustainable society. This paper provides a summary of such research and discusses the economic and commercial challenges associated with it.

Summary: Biomass combustion for electric energy production is associated with corrosion, especially at high temperatures and in the presence of chlorides. To mitigate this issue, more resistant steels can be used, co-combustion with biomass less loaded in alkalis and chlorides can be considered, sulfur compounds can be added to convert low melting point chlorides into higher melting point sulfates, or leaching treatment can be used to reduce compounds that affect the use of biomass.

Summary: This study investigated the nitrogen uptake from cover crop rhizodeposits by different domestication levels of wheat and barley. The results showed that domestication level was not related to the ability of cereals to take up nitrogen from rhizodeposits, and the nitrogen provision from rhizodeposits was driven by other factors like mineralization. However, some cultivars exhibited higher nitrogen uptake efficiency.

Summary: Organic farm management and the application of farmyard manure can promote the sequestration of soil organic carbon by improving the nutrient balance of macro- and micronutrients. However, there is a lack of quantitative information on micronutrients within the soil microbial biomass. This study investigated the effects of fertilisation differences and farm management on the soil microbial ionome and stoichiometry, and whether these changes are related to shifts in the microbial community. The results suggest that nutrient input and soil chemical properties play a major role in shaping the microbial stoichiometry and ionome, but the direct links between micronutrient stoichiometry and microbial community changes are uncertain due to potential confounding effects of pH changes.

Summary: The present study aimed to develop a method for assessing the elemental composition of soil microbial communities. Chloroform fumigation extraction was used to detect the concentrations of secondary and trace elements in soils. It was found that 0.01 M CaCl2 was the best-suited extractant, with a soil-to-extractant ratio of 1:20 and an extraction time of 1 hour. This method successfully extracted elements such as phosphorus, sulphur, potassium, sodium, magnesium, zinc, manganese, copper, nickel, vanadium, boron, silicon, and barium.
