DOI: 10.1002/ece3.9182
Abstract: Abstract Soil organic carbon (SOC) dynamics is regulated by a complex interplay of factors such as climate and potential anthropogenic activities. Livestocks play a key role in regulating the C cycle in grasslands. However, the… read more here.

DOI: 10.1007/s11104-021-04910-3
Abstract: Precrops exhibit vigorous deep root growth, especially when grown perennially. However, their contribution to accumulate essential nutrients derived from deeper soil layers in the topsoil has not been quantified. We determined the vertical distribution of… read more here.

DOI: 10.1007/s11204-018-9504-6
Abstract: The paper presents the well-known "mixed" problem solution for subsoil settlement analysis, accounting for soil cracks under footing edges whose depth is determined by iterations instead of abstract "plastic zones." read more here.

DOI: 10.1016/j.culher.2021.01.011
Abstract: Abstract Degradation of historical masonry and plasters is often caused by external conditions; the presented research focused on salts originating from subsoils. The content of salts: Sulphates, Nitrates and Chlorides was analysed from plasters on… read more here.

DOI: 10.1016/j.geoderma.2018.08.021
Abstract: Increasing subsoil organic carbon inputs could potentially mitigate climate change by sequestering atmospheric CO2. Yet, microbial turnover and stabilization of labile carbon in subsoils are regulated by complex mechanisms including the availability of nitrogen (N),… read more here.

DOI: 10.1021/acs.est.2c06419
Abstract: Biochar amendments add persistent organic carbon to soil and can stabilize rhizodeposits and existing soil organic carbon (SOC), but effects of biochar on subsoil carbon stocks have been overlooked. We quantified changes in soil inorganic… read more here.

DOI: 10.1128/msystems.00566-19
Abstract: Exploring the biogeographic patterns of soil microbial diversity is critical for understanding mechanisms underlying the response of soil processes to climate change. Using top- and subsoils from an ∼1,500-km temperate grassland transect, we find divergent… read more here.
