Soil mechanical impedance, hypoxia and water stress are the main soil physical causes of
reduced root growth, but they are rarely included in root growth models. The aim of this work …

Soil penetration resistance is an important indicator of soil physical quality and the critical
limit of 2 MPa has been widely used to characterize the soil physical quality, in both no …

Soil compaction has reduced crop yield under continuous no-tillage systems (NTS), and
occasional tillage has been suggested as a mitigating measure. The aim of this study was to …

The maintenance of sugarcane straw on the field has an important role in preserving the soil
properties and organic carbon content. However, there is a growing interest in removing part …

Background and aims Root elongation is generally limited by a combination of mechanical
impedance and water stress in most arable soils. However, dynamic changes of soil …

Hardpan is a major cause of land degradation that affects agricultural productivity in
developing countries. However, relatively, little is known about the interaction of land …

This study aimed to describe the behavior of models for adjusting data of soil penetration
resistance for variations in soil moisture and soil bulk density. The study was carried out in …

Soil compaction is a result of soil compression, and this effect depends on the pressure
applied and the soil structure. Nevertheless, studies regarding the effects of long-term tillage …

One of the most used evaluations to monitor soil compaction is based on soil penetration
resistance (SPR). However, since SPR is influenced by soil moisture, this evaluation …

The severe limitation of agricultural land productivity induced by physical soil degradation
has become a major concern in semiarid climates, especially in the Eastern Cape Province …
