“…From the 13 indicators used in this study, only three did not differ among orchards when normalized to their standardized score: EC, Tp, and WRC. This agrees with former studies showing that these properties tended to remain relatively stable in the soils of almond orchards along a toposequence [43] and in time despite contrasting soil management conditions [42,44]. In contrast, the remaining ten soil properties were able to detect considerable differences among almond orchards, most of them regarding aspects of soil fertility (OM, TOC, pH, CEC, TN, and AP), but also physical quality (BD) and potential restrictions to crop development (carbonates, active limestone, and AB contents).…”

“…Moreover, OM and nutrient availability were higher in San Martín than in Alacón and Valdealgorfa. This agrees with the observations from a recent study in Iran in which a survey of the soil from a mature almond orchard located on a hillslope was carried out [43]. This survey showed that the soil in the upper parts of the slope (summit and backslope, which can be assimilated to those from Alacón and Valdealgorfa) had lower TOC, TN, and AP contents than the soils in the lower parts of the slope (footslope and toeslope, which can be assimilated to that of San Martín).…”

“…The SQI calculated for the studied almond orchards were similar to those reported by Raiesi and Tavakoli [43] in Iran for the backslope of a toposequence, in the case of Alacón and Valdealgorfa, while the SQI of San Martín was similar to the almond orchards located in the footslope of the toposequence. However, these comparisons are not straightforward due to the different datasets of soil properties used in both studies, as well as the approach employed to compute the SQI.…”

Sustainable agriculture has drawn attention to the maintenance and enhancement of soil health. However, research on soil quality has been carried out mainly in field crops and, to a lesser extent, in mature orchards, neglecting the relevance of assessing the soil quality status in the first years of tree plantations. Therefore, the aim of this study was to assess the soil quality index of young almond orchards located in marginal lands and managed under different practices. The survey was carried out in the Teruel Province (Northeast Spain), in three almond orchards: Alacón (2 years old, 0.75 ha, rainfed, conventionally managed), San Martín (1 year old, 0.4 ha, irrigated, organically managed), and Valdealgorfa (6 years old, 0.2 ha, rainfed, organically managed). The composite soil samples were taken from three spots within each orchard. To determine the soil quality index, four main soil functions were considered: filtering and buffering, nutrient supply, water relations, and crop limitation. The soil quality indices were 0.55, 0.75, and 0.54 for Alacón, San Martín, and Valdealgorfa orchards, respectively. These values suggested that the evaluated soils are adequate for almond production, although they require management actions to improve their quality (for instance, the application of organic amendments) and increase the sustainability of these agroecosystems. Furthermore, this work provides a framework for the assessment of the soil quality in tree orchards at a young stage.

“…In these conditions, primary productivity should be increased. Soil quality index is significantly affected by landscape topography, which is a common observation in terrestrial ecosystems (Moradi et al, 2019;Raiesi and Tavakoli, 2022). In the present arid context, these lower slopes are a protection zone for trees, notably against tree dieback.…”

The intensive land use across the toposequence of sugarcane plantation has the potential to reduce soil quality, particularly due to the hazardous effect of erosion. Therefore, it is necessary to periodically evaluate the physical and chemical properties of the soil. The study was performed on Inceptisols in a sugarcane plantation area and aimed to investigate the effect of topography on soil quality. The soils sample were taken across the physiographic position (i.e., upper, middle, and bottom) of the study area. Nine soil samples were collected at 0-20cm depth, then composited into three samples according to the toposequence and analyzed using standard procedures. Among all the soil properties, texture, pH, organic-C, total-N, available P, and K were varied along the toposequence. It was observed a moderate soil quality index (SQI) at the bottom and upper of study site with a value of 0.54 and 0.44, respectively. Meanwhile, the low SQI was noted at middle (0.36). In the present study, the most crucial factors determining the variation in SQI were the soil texture, organic-C, and soil pH. The finding suggests the need of appropriate land use strategies and sustainable soil management practices to improve soil conditions in sugarcane plantation areas.
