The aim of this study was to evaluate how soil structure and root-length densities of annual
crops can be influenced by preceding crops. Three different annual field crops (spring wheat, …

Microbial activity in a sandy arable soil is governed by the fertilization regime

T Kautz, S Wirth, F Ellmer - European Journal of Soil Biology, 2004 - Elsevier
The aim of this study was to compare the influence of two different long-term organic

Root growth dynamics inside and outside of soil biopores as affected by crop sequence determined with the profile wall method

E Han, T Kautz, U Perkons, D Uteau, S Peth… - Biology and Fertility of …, 2015 - Springer
Taprooting crop species are capable of creating soil biopores (>2 mm in diameter) in the
subsoil due to their large root size and deep-rooting habit. The aim of this study was to quantify …

Modeling biopore effects on root growth and biomass production on soils with pronounced sub-soil clay accumulation

T Gaiser, U Perkons, PM Küpper, T Kautz… - Ecological …, 2013 - Elsevier
Soils with subsoil clay accumulation account for more than 20% of the global land surface.
These soils are characterized by vertical differences with respect to soil texture and …
