This research targets straw return in Farm 852's albic soil, China. The soil is nutrient-poor with few microbes and slow decomposition. Through fixed-point sampling bacterial screening, an actinomycete consortium consisting of four strains was assembled, two them were identified as new actinomycetes. After 7 days fermentation, the lignocellulose degradation rates this outstripped those single strains, cellulose degraded at 69.07%, hemicellulose 64.98%, lignin 68.95%. FTIR, XRD, SEM verified damage inflicted on structure. Lab simulations found group D (with consortium) had a higher weight loss rate than C commercialized microbial agents) controls. compound actinomycetes stepped up abundance passage time. In contrast, their effect fungal hardly noticeable, but they markedly ameliorated fertility. These findings prove that effectively accelerates decomposition boosts microbe fertility soil. It shows great potential for provides solution field.

In recent decades, much of China’s farmland has been transformed into forests due to the Conversion Farmland Forests and Grasses Project. While past research mainly examined soil nutrients water conservation, less attention given microbial communities. This study effects converting Pleioblastus amarus (PA), Populus deltoides (PD), or Zanthoxylum bungeanum (ZB) on physiochemical properties, enzymes, communities, using abandoned land (AL) as control, over a period five years. The results showed that PA increased organic carbon (SOC) content, although not significantly, while significantly boosting C:N C:P ratios urease activity compared AL.

Carbonate rock dissolution (CRD) in karst areas generates abundant ions, which contribute significantly to nitrogen (N) transformation paddy ecosystems. However, little is known about the microbial mechanisms by CRD ions (Ca2+, Mg2+, HCO3−/CO32−, and OH-) regulate N balance. In this experiment, rice pot studies were conducted using soil (S1), with removed carbonate minerals (S2), non-karst (S3), additional (S4). The effects of on N-metabolizing microorganisms functional genes metabolism investigated metagenomic sequencing technology. Six pathways, including fixation, nitrification, denitrification, dissimilatory nitrate reduction ammonia (DNRA), assimilatory (ANRA), complete nitrification (comammox) revealed.

Here, we conducted a microcosm experiment to investigate influences increasing microbes such as bacteria eukaryotic microbes. Denitrification rate in were detected using C2H2 inhibition method. The results showed that Shannon index bacterial exhibited significant enhancement response whereas their community patterns predominantly shaped pH. For micro-eukaryotic community, emerged main driver variations α-diversity, with MT group exhibiting significantly lower indices compared LT HT groups. Both exerted effect patterns. Additionally, was crucial factor influencing rates, negative correlation between within range 4.32-7.46 across all temperatures this study.
