Bublitz T., Kemper R., Müller P., Kautz T., Döring T., Athmann M. (2021.0). Relating Profile Wall Root-Length Density Estimates to Monolith Root-Length Density Measurements of Cover Crops. Agronomy, 12(1), 48. doi:10.3390/agronomy12010048

Different methods have been proposed for in situ root-length density (RLD) measurement. One widely employed is the time-consuming sampling of soil cores or monoliths (MO). The profile wall (PW) method is a less precise, but faster and less laborious alternative. However, depth-differentiated functio…

Koch M., Boselli R., Hasler M., Zörb C., Athmann M., Kautz T. (2021.0). Root and shoot growth of spring wheat (Triticum aestivum L.) are differently affected by increasing subsoil biopore density when grown under different subsoil moisture. Biology and Fertility of Soils, 57(8), 1155-1169. doi:10.1007/s00374-021-01597-7

AbstractA column experiment with five different pore densities (0, 1, 2, 3, and 4 pores column−1) and two varying moisture regimes (comparatively dry and comparatively moist regime) in the subsoil part of the columns was established. In each pore, Lumbricus terrestris was introduced for 28 days befo…

Crop response to P fertilizer omission under a changing climate - Experimental and modeling results over 115 years of a long-term fertilizer experiment. Field Crops Research, 268(), 108174. doi:10.1016/j.fcr.2021.108174

Phosphorus (P) is an essential plant nutrient. However, our understanding of the complex interactions between soil P availability, environment, management and crop growth is still limited. We used unique historic and recent soil and crop data spanning more than a century combined with a process-base…

Bauke S., Schnepf A., Sperber C., Orlowski N., Lewandowski H., Selzner T., Tamburini F., Amelung W. (2021.0). Tracing uptake and translocation of phosphorus in wheat using oxygen isotopes and mathematical modelling. New Phytologist, 230(5), 1883-1895. doi:10.1111/nph.17307

Understanding P uptake in soil–plant systems requires suitable P tracers. The stable oxygen isotope ratio in phosphate (expressed as δ18OP) is an alternative to radioactive labelling, but the degree to which plants preserve the δ18OP value of the P source is unclear. We hypothesised that the source …

Han E., Li F., Perkons U., Küpper P., Bauke S., Athmann M., Thorup-Kristensen K., Kautz T., Köpke U. (2021.0). Can precrops uplift subsoil nutrients to topsoil?. Plant and Soil, 463(1-2), 329-345. doi:10.1007/s11104-021-04910-3

Purpose 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 phosphorous (P) and potassium (K) af…

Chiba A., Uchida Y., Kublik S., Vestergaard G., Buegger F., Schloter M., Schulz S. (2021.0). Soil Bacterial Diversity Is Positively Correlated with Decomposition Rates during Early Phases of Maize Litter Decomposition. Microorganisms, 9(2), 357. doi:10.3390/microorganisms9020357

This study aimed to investigate the effects of different levels of soil- and plant-associated bacterial diversity on the rates of litter decomposition, and bacterial community dynamics during its early phases. We performed an incubation experiment where soil bacterial diversity (but not abundance) w…

Wang Y., Wu B., Berns A., Bol R., Wombacher F., Ellmer F., Amelung W. (2021.0). A century of liming affects the Mg isotopic composition of the soil and crops in a long‐term agricultural field at Berlin‐Dahlem, Germany. European Journal of Soil Science, 72(1), 300-312. doi:10.1111/ejss.12951

Liming is widely used to alleviate soil acidity in western and central Europe, but its role in the cycling of magnesium (Mg) in arable soil–plant systems is still ambiguous. Here, we systematically analysed Mg concentrations and the natural Mg stable isotope compositions (δ26Mg) of two Mg pools in s…

We provide strontium isotope data (for both the "radiogenic" isotope ratio 87Sr/86Sr, and the "stable" isotope ratio 88Sr/86Sr, expressed as delta88Sr) for critical zone compartments (rock, saprolite, soil, plants, and river dissolved loads) at three sites along a global transect of mountain landsca…

Wu B., Wang Y., Berns A., Schweitzer K., Bauke S., Bol R., Amelung W. (2021.0). Iron isotope fractionation in soil and graminaceous crops after 100 years of liming in the long‐term agricultural experimental site at Berlin‐Dahlem, Germany. European Journal of Soil Science, 72(1), 289-299. doi:10.1111/ejss.12944

Sustainable arable cropping relies on repeated liming. Yet, the associated increase in soil pH can reduce the availability of iron (Fe) to plants. We hypothesized that repeated liming, but not pedogenic processes such as lessivage (i.e., translocation of clay particles), alters the Fe cycle in Luvis…
