Microbial hotspots and hot moments in soil: Concept & review

Allocation of photosynthestically-fixed carbon in plant and soil during growth of reed (Phragmites australis) in two saline soils

“…Secondly, the 13 C contribution was diluted by the newly unlabeled photosynthetically-fixed C as reed growth proceeded (Rangel-Castro et al 2004). Thirdly, the stronger nutrient competitive abilities for reed demand resulted in smaller size of the rhizosphere microbial biomass (Blagodatskaya et al 2010;Kuzyakov and Blagodatskaya 2015) during reed growth, as shown by the reed N uptake under the N-limited condition in our study (Fig. S3).…”

“…Soil salinity therefore affected the quantity of deposited C, and soil texture altered the allocation of rhizodeposition C in different soil particles. This study suggests that a better understanding of the effects of salinity on soil C storage is required in relation to C transformation and stabilization in various soil pools closely linked with the contribution of plant growth and soil available nutrients (Six et al 2002;Xiao et al 2007;Kuzyakov and Blagodatskaya 2015). Further studies are required on the C storage potential and C stability and availability in MAOC pools.…”

“…S4). In addition, the rhizosphere transformed to the detritusphere with root death or root development, accordingly, the low-molecular-weight materials from root deposition became recalcitrant highly polymeric compounds, the microbial turnover rate of root-deposited C decreased (Kuzyakov and Blagodatskaya 2015). Consequently, the duration of root-deposited C in the earlier pulses will increase on the final day.…”

Making big data smart—how to use metagenomics to understand soil quality

“…Thus, one sampling time point does not help to understand the complexity of microbiomes at a given site but is often a snapshot, which is strongly influenced by the recent local conditions. Taking these strong dynamics of soil microbiomes in time and space (Kuzyakov and Blagodatskaya 2015) into account, the sampling strategy should be driven by a clear research hypothesis.…”

Humusica 2, article 16: Techno humus systems and recycling of waste

“…It is possible to accelerate the process of biodegradation, mix thus formed horizons, adding new material, aerating the pile and destroying/orienting/modifying a natural system in formation. With these operations, farmers and gardeners purposely interfere with the natural process of organic matter decomposition and transform natural humus systems into Techno humus systems (Mustin, 1987;Culot and Lebeau, 1999;Tuomela et al, 2000;Ouédraogo et al, 2001;Fontaine et al, 2003;Annabi et al, 2005;Ros et al, 2006;Saison et al, 2006;Evanylo et al, 2008;Adani et al, 2009;Lowenfels and Lewis, 2010;Brown and Cotton, 2011;Zhao et al, 2013;Lowenfels, 2014;Gerbier, 2015;Kuzyakov and Blagodatskaya, 2015;Lowenfels, 2017).…”
