“…The deficient hydrological integrity of the soils under E, PP, and PH is clear from their extremely low hydraulic conductivity and infiltration rates, compared to PM and G, indicating high runoff even in rainfall events with low intensity. The low infiltration and hydraulic conductivity are strongly conditioned by the poor soil structure, including pore size distribution and morphology (Fernández et al, 2021). This is probably aggravated by the hydrophobicity of the forest floor under these species.…”

Land-use change and specifically a change in the type of vegetation cover affects soil morphology, chemistry, biology, and nutrient regimes. Numerous studies have documented that in land-use conversions from agricultural land to forest, or from plantations to restored natural savanna most soil attributes and functions undergo changes. The purpose of the present study was to evaluate the changes brought about by afforestation of degraded croplands and to understand the impact of forest vegetation on soil evolution in a semiarid region where soils originally co-evolved with a savanna biotope. We used long-term experiments (>40 years) of five tree species: Pinus halepensis (PH), Pinus halepensis inoculated with ecto-mycorrhiza at planting (PM), Pinus pinea (PP), Eucalyptus spp. (E), and Gleditsia triacanthos (G) and compared these to an agricultural soil (A) at the same site near Santa Rosa, La Pampa in the semiarid center of Argentina. Soil profiles were described, and samples taken for chemical and physical analyses of soil properties [organic matter (OM), pH, cation exchange capacity (CEC) and exchangeable cations, particle size distribution (texture), aggregate stability (MWD), bulk density (BD), porosity (TP), and water holding capacity (WHC)]. We found a strong effect of tree species on soil profile morphology, even taxonomy, and on all studied variables. PM and G had highest OM, CEC, neutral pH, higher TP, WHC, while PH, PP, and E had acid pH, lower base saturation, OM, TP, and WHC. The effect of tree species on the soil profile was noticeable a depth of about 40 cm, comprising the A and AC, but not the C horizons. The results showed that to obtain reasonable results of OM sequestration under forest systems, tree species should be chosen to include legumes to improve C/N stoichiometry for C fixation, or inoculation with mycorrhiza to promote microbial transformation of forest litter.

“…Soil organic carbon contents in soils significantly impact the soil systems, so an assessment of organic and inorganic components needs to be developed (Sreenivas et al, 2016). Fernández et al (2021) reported total organic carbon between 7.9 to 69.2 g/kg and 6.6 to 14.1 g/ kg in natural vegetation vs agricultural practices in Mollisol, while total porosity was recorded as 56.0 to 68.2 vs 33 to 45.8 per cent in the two systems respectively. Of course, bulk density of 0.85 to 1.1 and 1.22 to 1.37 g/cc was noted across systems and structural instability index was estimated at 0.39 to 0.61 vs 1.28 to 1.68 indicating the fact that land use practices do impact the soil physico-hydrological behaviour tremendously.…”

The present study aimed to assess the soil indicators for developing an information system for mango orchards of famous Malihabad, Lucknow, UP, India. Scientific analysis showed maximum nutrient indexing values as 2.00, 2.00, 2.00, 1.00, 2.50, 1.50, 2.00 and 2.00 for soil organic carbon, soil available phosphorus, potassium, nitrogen, zinc, copper, manganese and iron, respectively. The distribution pattern indicated 100 per cent low in Cu and N, and a medium level for Mn and Fe. Soil phosphorus and soil organic carbon had 100 per cent in medium (14 mango orchards) and low (10 mango orchards) distribution, while potassium had only in 8 mango orchards. Histographic distribution of soil physical indicators showed that the maximum frequency level (30 per cent) falls into the porosity of 35 to 40 per cent, whereas the 16 per cent frequency level of water holding capacity in 18 to 19 per cent intervals. Bulk density and particle density were 1.5 to 1.6 with a 30 per cent frequency level and 2.4 to 2.5 g/cc with a 17 per cent frequency level. It was inferred from the information system that soil indicators were low to medium ranks significantly related to lower productivity of <20 t ha -1 . The histographic distribution of the soil information system showed a wider pattern and emphasized the urgent scope of improving the soil health condition of mango orchards.

“…As highlighted in Fernández et al (2021), the agricultural use of land leads to degradation of the soil structure, which, in turn, aggravates and impacts the natural characteristics. To reverse this process, significant indicators that reflect the degree of damage to the soil system.…”

Several studies have shown that negative changes in physical attributes affect root growth and plant development. Thus, the objective of this work was to evaluate the impacts of forest-agricultural conversion on the physical-water attributes of the soil in the Amazon basin, southeastern Brazil. The study was carried out in Canutama - AM, in which areas of annatto, cupuaçu and guarana cultivation and a forest area were selected. Meshes of 90 m x 70 m, 90 m x 56 m and 54 m x 42 m were established, comprising 80 sampling points per layer. The points were georeferenced and the undisturbed soil samples were collected in volumetric rings to determine the physical and hydric attributes. data were submitted to descriptive statistics and multivariate analysis. It was observed that aspects such as the implementation time of the different use and occupation systems can be controlling factors for the restoration of these physical properties.
