Due to their substantial volume, subsoils contain more of the total soil carbon (C) pool than
topsoils. Much of this C is thousands of years old, suggesting that subsoils offer …

Plant root traits play a crucial role in resource acquisition and crop performance when soil
nutrient availability is low. However, the respective trait responses are complex, particularly …

Soil compaction caused by vehicular traffic adversely affects key soil functions and
ecosystem services that soils provide. Although compaction is a well-recognized problem, it …

Soil organic matter (SOM) accumulation is different in certain soil groups with differences in
parent material, degree of weathering and mineral composition. These differences are …

Soils are the most heterogeneous parts of the biosphere, with an extremely high
differentiation of properties and processes within nano-to macroscales. The spatial and …

The subsoil below the regularly tilled topsoil stores large nutrient stocks and can retain water
even under drought conditions. Mechanical soil profile modifications, commonly referred to …

In the quest for sustainable intensification of crop production, we discuss the option of
extending the root depth of crops to increase the volume of soil exploited by their root …

No-tillage with straw mulch is an effective way to achieve soil sustainability. However, the
