“…It is important to note that BD was higher in AR compared to CL regardless of the study period (long-term and short-term) (Tables 4 and 5). The studied soils have shown that BD decreased significantly in NC-CL and OC-CL; in this line, [57] confirmed that in temperate zones, a decrease in BD is related to an increase in calcium carbonate content. BD values tended to be higher in surface horizons than in deep layers specifically in CL.…”

Soil organic carbon (SOC) plays an important role in the global C cycle, as well as in the maintenance and improvement of the soil quality. Over time, special attention has been paid to it in the study of the SOC reserves worldwide; however, reduced attention has been given to assessing the spatial patterns of SOC stock (SOCS) in semi-desert ecosystems. In this line, there are no conclusive studies in drylands of Africa affected by aeolian processes (semi-desert conditions) mainly due to the complexity of sample collection, and this is especially significant in some soil types such as Arenosols (AR) and Calcisols (CL). This study evaluated the spatial variability of SOC and SOCS in AR and CL with woody crops in relation to land use and management (old plantations > 100 years: centenary olive grove; new plantations < 12 years: young olive grove, almond, and pistachio) in semi-desert conditions. For this purpose, 16 soil profiles (for 0–40 and 40–100 cm depth) were selected and studied in an experimental area of Menzel Chaker-Sfax in southeastern Tunisia (North Africa). The main results indicated that the SOCS on average was higher in Old Cultivated AR (OC-AR) with 41.16 Mg ha−1 compared to Newly Cultivated AR (NC-AR) with 25.13 Mg ha−1. However, the SOCS decreased after a long period of cultivation in CL from 43.00 Mg ha−1 (Newly Cultivated CL: NC-CL) to 32.19 Mg ha−1 (Old Cultivated CL: OC-CL). This indicates that in the long term, CL has more capacity to store SOC than AR, and that in the short term, AR is more sensitive to land management than CL.

“…In soils occupying a lower position in the relief (PH/GL), the SOCS were clearly greater and ranged from 6.3 to 38.1 kg m -2 . Similar variation in SOCS values was obtained within sequence of erosional/colluvial soils located on Vistula Valley slopes (OEwitoniak et al 2015). Data presented in samples were air-dried and ground to pass through 2 mm sieve prior to analysis.…”

The paper presents the results of research on the relationship between topography of undulated morainic plateau of postglacial landscape and distribution of organic carbon stocks in soil toposequences. The mean value of the soil organic carbon stocks (SOCS) for Retisols/Luvisols (RT/LV) was statistically lower than for the Phaeozems/Gleysols (PH/GL) but for RT/LV a higher variation of SOCS in comparison to PH/GL was observed. On the basis of Pearson correlation coefficient, the cartographic depth to water (DTW), the topographic wetness index (TWI) and the saga wetness index (SWI) were the most strongly correlated with the SOCS from among 13 analysed topographic attributes. In addition, the DTW was more correlated with SOCS than other topographic variables. Moreover, the DTW based on the channel networks with 2 ha flow initiation thresholds better correlate with SOCS than DTW obtained on the basis of channel networks with 1 ha and 4 ha flow initiation thresholds. Using Stepwise multiple regression analysis (SMLR), we concluded that the topographic attributes controlling the soil water content and slope shape had most impact on SOCS of the undulated morainic plateau of agricultural ecosystem. In this landform, where the RT/LV and PH/GL soil sequences dominate, the SOCS can be estimated by the DTW, TWI and GC (general curvature) with an estimation error of 0.21 kg m−2. In view of the increasing availability of LiDAR data and power of GIS tools, the use of topographic metrics to assess spatial variability of soil properties will play an increasingly important role in the estimation of soil properties.

“…Soil aggregates and their stabilities play an important role in the soil environment. The literature describes the influence of different natural factors on the processes of aggregate formation (Kumar, Rawat, Singh, Singh, & Rai, ; Lehmann & Rillig, ; Lipiec, Brzezińska, Turski, Szarlip, & Frąc, ), and anthropogenic influences are commonly investigated (Glina et al, ; Makó, Csatári, Barna, Földényi, & Tóth, ; Šimanský, Polláková, Jonczak, & Jankowski, ; Świtoniak, Dąbrowski, & Łyszkiewicz, ). Information about aggregate structure is useful for soil science researchers' activities.…”

An improved method for determination of aggregate stability using laser diffraction

et al. 2018

Soil aggregate water stability is very important from both scientific and practical points of view. This stability is a critical factor in a soil's susceptibility to water erosion and, in turn, land degradation. The most popular measure of soil aggregate stability is the water resistance index (WRI), which is commonly measured using the wet‐sieving method. Using the laser diffraction method in order to observe changes in the median of the particle size distribution and determine soil aggregate stability was first proposed in 2010. However, the method was not suitable for weak aggregates. The aim of this study was to present a measure of aggregate stability using laser diffractometry, aggregate stability index (ASILD). Determination of the ASILD is based on the calculation of the directional coefficient of the straight line interpolated from 2 points: (a) the value calculated as the mean of the lower and upper nominal sieve sizes used for soil aggregate separation and (b) the median of the first measurement after the adding of the dry aggregates into the measuring system of the laser diffractometer. This proposed method for the calculation of the ASILD can be applied to very weak aggregates (i.e., aggregates that, in practice, are not at all water resistant). For weak and moderately stable aggregates, the correlation between ASILD and WRI is higher than 0.9. This method also enables differentiation between the water resistance of aggregates which, by the wet‐sieving method, are indistinguishable (i.e., those which have the maximum WRI).
