Estimating sample size of soil cone index profiles by bootstrapping
(Sociedade Brasileira de Ciência do Solo, 2017-11)
Measurements of the soil cone index are widely used to assess soil resistanceto root penetration (SR) and to monitor the soil compaction status of agricultural fields. However, soil sampling for SR estimation is a rather ...
Pore morphology reveals interaction of biological and physical processes for structure formation in soils of the semiarid Argentinean Pampa
(Elsevier, 2019-08-01)
In order to obtain baseline values for the evaluation of soil degradation, the biological and physical quality of petrocalcic Paleustolls, of the calcrete plains of the Semiarid Region Pampa of Argentina, soils under ...
Estimation of specific yield and its variability by electrical resistivity tomography
(American Geophysical Union, 2018-10)
Specific yield (Sy) is defined as the average volume of water that can be drained, per unit surface of aquifer per unit drop of head. This parameter is of critical relevance for groundwater resources assessment, but its ...
The adoption of no-till instead of reduced tillage does not improve some soil quality parameters in Argentinean Pampas
(Elsevier Science, 2016-02)
No-till (NT) has been recognized worldwide as a more suitable system than tillage for enhancing soil quality. However, several concerns remain about its conservative nature, especially when it is performed either without ...
Kirchhoff and Ohm in action: solving electric currents in continuous extended media
(IOP Publishing, 2018-01)
In this paper we show a simple and versatile computational simulation method for determining electric currents and electric potential in 2D and 3D media with arbitrary distribution of resistivity. One of the highlights of ...
Electrical Parameters Associated With Discharges in Resistive Soils
(IEEE, 2004-12)
The electrical parameters associated with discharges in resistive soils have been studied under inhomogeneous fields in order to achieve a better understanding of the nonlinear behavior of rounding systems subject to high ...
Comparing adjacent cultivated and “virgin” soils in wind erosion affected environments can lead to errors in measuring soil degradation
(Elsevier, 2016-02)
Soil degradation has been frequently evaluated by comparing cultivated soils with paired reference pedons. Evaluated were some physical and chemical properties of cultivated and reference soils of a semiarid environment ...
Spatial distribution of soil mechanical strength in a controlled traffic farming system as determined by cone index and geostatistical techniques
(Eesti Pollumajandusulikool, 2020-05)
Controlled traffic farming (CTF) is a mechanisation system in which all load-bearing wheels are confined to the least possible area of permanent traffic lanes and where crops are grown in permanent, non-trafficked beds. ...
Soil dry aggregate stability and wind erodible fraction in a semiarid environment of Argentina
(Elsevier Science, 2010-10)
The size and stability of soil aggregates are primary factors that affect the soil susceptibility to wind erosion. Relationships among several soil properties and both the wind erodible fraction (EF) and the dry aggregate ...
Soil dry aggregate stability and wind erodible fraction in a semiarid environment of Argentina
(2010-10)
The size and stability of soil aggregates are primary factors that affect the soil susceptibility to wind erosion. Relationships among several soil properties and both the wind erodible fraction (EF) and the dry aggregate ...
