They provide<br>\nnumerous ecosystem services such as habitat for biodiversity, water and nutrients, as well as<br>\nproducing food, feed, fiber and energy. Soils undergo intense and irreversible changes due to<br>\na non-site adjusted land management and improper application of machinery and techniques<br>\nin its broadest sense. In combination with the growing population (until 2050 we will have<br>\napprox. 9 Billion people) the urgent need for a more reliable dataset of soil properties and soil<br>\nfunctions gains in importance in order to even prepare more reliable models for various<br>\nrequests. The mechanical strength – the precompression stress - as the result of geo-, pedoand<br>\nanthropogenic long-term processes - can be defined as the basis for quantifying the<br>\nrigidity boundary. It distinguishes between the recompression stress (i.e. elastic, rigid<br>\nproperties) and the virgin compression stress range where plastic deformation including<br>\nirreversible changes of properties and functions occur. The changes in the hydraulic or<br>\npneumatic functions like hydraulic or air conductivity, the pore size distribution primarily all<br>\noccur in the virgin compression stress range, The same is also true for redox reactions and the<br>\nbiological activity (respiration) in soils but also carbon sequestration potential is also linked<br>\nwith the precompression stress value. Thus, a more precise definition and following of sitespecific<br>\nfunctionality differences, which may exclude or concentrate certain land use or<br>\nmanagement forms are needed, in order to optimize yield, soil protection and a sustainable<br>\nland use management considering the limited site specific resilience at the same moment.</p>", "author": [ { "family": "Horn, Rainer" } ], "page": "3 - 15", "volume": "4", "type": "article-journal", "issue": "1", "id": "3250776" }
