“…is is inferred from what was found in regions with similar texture in "Maria da Conceição," probably due to the presence of native vegetation. Studying Haplic Cambisols, Oliveira et al [27] found that preserved forest areas presented the best water retention conditions, which is significantly correlated with S [35], thus endorsing the conjecture in the present work. Moreover, as illustrated in Dexter [11], the S index is mostly determined by soil organic carbon, being positively correlated [36], since organic carbon can increase water retention and improve pore distribution [37].…”

Land use and soil physical quality are related. In this work, the S index was used to evaluate the physical quality of the soils of three rural settlement units located in the Brazilian Cerrado, with areas ranging from 700 to more than 4000 hectares, based on a novel method. To map the S index, a set of pedotransfer functions for water retention curves was adapted according to a broad range of clay content for Cambisols, in three depth layers. Some rural units presented associations with classes of land use. In general, deeper layers presented higher values of S. In areas with less than 370 g/kg of clay, land uses that provide low soil cover should be avoided to prevent physical degradation.

“…The silt loam is the predominant soil texture. The SD values (Tables 3 and 4) for most soil properties are large, indicating moderate to strong variability; this is not uncommon for soils [12,57,58]. Typically, the CV values are < 45%, indicating the mean variability of the measurement data.…”

A key parameter for the design of soil drainage and irrigation facilities and for the modelling of surface runoff and erosion phenomena in land-formed areas is the saturated hydraulic conductivity (Ks). There are many methods for determining its value. In situ and laboratory measurements are commonly regarded as the most accurate and direct methods; however, they are costly and time-consuming. Alternatives can be found in the increasingly popular models of pedotransfer functions (PTFs), which can be used for rapid determination of soil hydrophysical parameters. This study presents an analysis of the Ks values obtained from in situ measurements conducted using a double-ring infiltrometer (DRI). The measurements were conducted using a laboratory permeability meter (LPM) and were estimated using five PTFs in the Rosetta program, based on easily accessible input data, i.e., the soil type, content of various grain sizes in %, density, and water content at 2.5 and 4.2 pF, respectively. The degrees of matching between the results from the PTF models and the values obtained from the in situ and laboratory measurements were investigated based on the root-mean-square deviation (RMSD), Nash–Sutcliffe efficiency (NSE), and determination coefficient (R2). The statistical relationships between the tested variables tested were confirmed using Spearman’s rank correlation coefficient (rho). Data analysis showed that in situ measurements of Ks were only significantly correlated with the laboratory tests conducted on intact samples; the values obtained in situ were much higher. The high sensitivity of Ks to biotic and abiotic factors, especially in the upper soil horizons, did not allow for a satisfactory match between the values from the in situ measurements and those obtained from the PTFs. In contrast, the laboratory measurements, showed a significant correlation with the Ks values, as estimated by the models PTF-2 to PTF-5; the best match was found for PTF-2.

The BD values greater than 1.25 1.30 g•cm -3 could cause yield loss due to poor soil aeration (Borek, 2019).

The quantity and quality of yield is determined by the soil quality. The agriculture is one of the main human activities that affect soil quality. In Dolj, the agriculture occupies an important place in the economy of the County. The main soils found in DoljCounty were Chernozems and Luvisols. Several indicators are used to quantify the physical quality of the soil. To assess soil physical quality, disturbed samples from each pedogenetic horizon were collected to analyse: particle size distribution, soil organic content, dispersion and macrohydrostability. Undisturbed samples were also collected (by using a core sampler), for: bulk density, total porosity, saturated hydraulic conductivity, resistance to penetration determination. The degree of compaction, the packing density, the structural stability index as well as the structural instability index were obtained by calculation. The results showed that according to the degree of compaction values, both studied Luvisols (except ArenicLuvisols), and HyposodicCalcaro-calcic Chernozems and Haplic Chernozems with fine texture were severely compacted and required loosening works. Most of the studied horizons of Luvisols had low – extremely low permeability. With a few exceptions, the values of the resistance to penetration were medium. The HyposodicCalcaro-calcic Chernozems shows the highest values of structural instability index.
