Modelling structural changes in tilled topsoil over time as a function of cropping systems

Abstract: The optimization of tillage practices requires the evaluation of the long-term effects of cropping on changes in soil structure. A model is presented that simulates changes in soil structure in the tilled horizons of cultivated ®elds. The indicator of soil structure that we have modelled is based on a morphological description of the structure and the assessment of the percentage of severely compacted zones and clods showing no visible porosity in the tilled layer of a soil pro®le. The model takes into account… Show more

“…During most agricultural practices, mechanized cultivation disturbs the soil, causing fragmentation, compaction and displacement (Roger-Estrade et al 2000). Consequently, two types of earth may appear within the soil profile: fine and compacted zones (most often defined as clods).…”

“…Although the soil was tilled every year, the material distribution in the tilled layer was kept constant. This choice was supported by the fact that the overall structure of the tilled layer reaches a steady state within a few years under constant agricultural practices (Roger-Estrade et al, 2000) which was the case in the current experiment. The BT and BT/IC horizons were divided into two layers in order to correspond with the field measurements (TDR, tensiometers) installed at two different depths within these horizons.…”

“…This method is used to describe the soil structure of the tilled layer of agricultural fields. It is based on the visual observation of soil macroscopic features on the vertical face of a large soil pit oriented perpendicular to the tillage direction (Coutadeur et al, 2002;Roger-Estrade et al, 2000). The soil profile was divided into vertical and horizontal compartments according to the effects of the tillage implements and the internal structure of each of these compartments.…”

“…It enables researchers to establish links between soil structure and other factors, such as root development (Roger-Estrade et al, 2000a;Mentges et al, 2016), the availability and distribution of minerals (Vizier et al, 1995), and hydrodynamic characteristics (Mentges et al, 2016).…”
