“…Beyond the insights gained from this study, more research is needed encompassing a broader diversity of soils, biophysical conditions, and long‐term recurrent N inputs. We hypothesize that repeated N fertilizer applications will create inherent priming of the soils—similar to soil biological memory (Banerjee et al., 2016; Targulian & Bronnikova, 2019; Thilakarathna & Hernandez‐Ramirez, 2020)—by selecting, training, and acclimating microbial activity for rapid utilization of N added in large, recurrent pulses. This notion is in line with Thilakarathna and Hernandez‐Ramirez (2020), who recently reported legacy effects of annual, long‐term urea additions on the positive priming of N 2 O fluxes from soils continuously cropped to barley.…”

Adding nitrogen fertilizers to agricultural soils contributes to increasing concentrations of nitrous oxide (N2O) in the atmosphere. However, the impacts of N addition on soil organic matter (SOM) turnover, SOM availability, and the ensuing SOM‐derived N2O emissions remain elusive. Within this context, the net change in direction and rate of SOM‐derived N2O production triggered by added N is termed the N2O priming effect. This incubation study examined the sources and priming of N2O production as a function of urea addition and multiple moisture contents in a soil with high SOM (55 g organic C kg−1). We assessed four water‐filled pore space (WFPS) conditions: 28, 40, 52, and 64%. Relative to controls receiving no N, urea addition increased N2O production by 2.6 times (P < .001). Cumulative N2O production correlated well with nitrification rates (r = .75; P = .03). We used 15N‐labeled urea to trace the added urea into N2O. Of the N added via urea, the recovery as N2O–N shifted from 0.02 to 0.17% when WFPS increased from 28 to 64% (P < .05). We also partitioned the N2O production into urea vs. SOM sources. More N2O was sourced from SOM than urea, with 59 ± 2% N2O originating from SOM. The magnitude of SOM‐derived N2O under urea was larger than that of the control, revealing that positive N2O priming was triggered by urea addition. Upon subtracting the controls, the primed N2O was a consistent 19 ± 2% of the total N2O produced by urea‐amended soils. Nevertheless, the priming magnitude rose sharply with increasing moisture by more than one order of magnitude from 4 to 48 μg N2O–N kg−1 soil and in exponential mode (R2 = .98). Soil moisture, SOM, and nitrification interacted to drive the sources and priming of N2O.

“…According to Targulian, every disruption of the soil surface sets soil formation process, or pedogenesis, to zero ( Targulian & Bronnikova, 2019 ). Thus, different stages of the pedogenesis can be approached by studying chronosequences, which are series of soils, formed at different times under similar climatic and biogenic conditions ( Emmer, 1995 ; Mokma, Yli-Halla & Lindqvist, 2004 ; Cerli et al, 2008 ; Abakumov et al, 2010 ).…”

Microbiomes of different ages in Rendzic Leptosols in the Crimean Peninsula

Rendzic Leptosols are intrazonal soils formed on limestone bedrock. The specialty of these soils is that parent rock material is more influential in shaping soil characteristics than zonal factors such as climate, especially during soil formation. Unlike fast evolving Podzols due to their leaching regime, Leptosols do not undergo rapid development due to the nature of the limestone. Little is known how microbiome reflects this process, so we assessed microbiome composition of Rendzic Leptosols of different ages, arising from disruption and subsequent reclamation. The mountains and foothills that cover much of the Crimean Peninsula are ideal for this type of study, as the soils were formed on limestone and have been subjected to anthropogenic impacts through much of human history. Microbiomes of four soil sites forming a chronosequence, including different soil horizons, were studied using sequencing of 16S rRNA gene libraries and quantitative PCR. Dominant phyla for all soil sites were Actinobacteria, Proteobacteria, Acidobacteria, Bacteroidetes, Thaumarchaeota, Planctomycetes, Verrucomicrobia and Firmicutes. Alpha diversity was similar across sites and tended to be higher in topsoil. Beta diversity showed that microbiomes diverged according to the soil site and the soil horizon. The oldest and the youngest soils had the most similar microbiomes, which could have been caused by their geographic proximity. Oligotrophic bacteria from Chitinophagaceae, Blastocatellaceae and Rubrobacteriaceae dominated the microbiome of these soils. The microbiome of 700-year old soil was the most diverse. This soil was from the only study location with topsoil formed by plant litter, which provided additional nutrients and could have been the driving force of this differentiation. Consistent with this assumption, this soil was abundant in copiotrophic bacteria from Proteobacteria and Actinobacteria phyla. The microbiome of 50-year old Leptosol was more similar to the microbiome of benchmark soil than the microbiome of 700-year old soil, especially by weighted metrics. CCA analysis, in combination with PERMANOVA, linked differences in microbiomes to the joint change of all soil chemical parameters between soil horizons. Local factors, such as parent material and plant litter, more strongly influenced the microbiome composition in Rendzic Leptosols than soil age.

“…While soils in general are an important source on the changes in the natural environment in the Holocene, soils that have experienced long-term agricultural loads preserve the record of these activities in their physicochemical and biogeochemical properties (or pedomemory), shedding light on the mechanisms of agrogenic soil evolution [42,43]. e framing of the concept of soil memory and the perception of soils and soil cover as specific carriers of information about the evolution and interaction of the biosphere, geosphere, and human society signify an important milestone in the development of pedology [44].…”

As an effect of intensive agricultural development of the steppes of the northern Black Sea coast, the finds of postantique agricultural landscapes that preserve relic elements of ancient land-use infrastructure are extremely rare. To these belongs the uniquely preserved ancient Greek land division system on the Tarkhankut Peninsula (north-western Crimea), which was studied using the methods of soil science and biomorphic analysis. This paper explores ancient land-use practices in order to reconstruct the original parameters of the land division system, as well as agricultural techniques employed. For postantique agricultural landscapes, an integrated geoarchaeological approach that includes GIS and remote sensing methodologies, in-field study of microrelief and soil registrograms, pedochronological dating technique, and physicochemical, geochemical, and biomorphic soil analyses has been developed and tested. The soil-geomorphological reconstruction shows that the Hellenistic land division system included a 4.5–4.9 m wide strip of land bordered by a 4.1–4.7 m wide (at the base) and c. 0.2 m high wall and a c. 2 m wide and over 15 cm deep trench, which controlled surface runoff and erosion. Ancient agricultural practices of slope farming resembled the modern ones. Surface runoff and soil erosion were controlled by dividing the catchment area into narrow plots, the borders of which on arable land were marked by simple earthen structures (low walls with shallow trenches). The biomorphic analysis of soil sampled atop these structures indicates that in ancient times, these earthen walls were not cultivated. The study of conservative properties preserved in pedomemory of postagrogenic soils provided valuable evidence of agricultural techniques used in the palaeogeographic conditions of the 4th and 3rd centuries BC.
