“…The use of nitrate-based fertilisers (e.g., calcium ammonium nitrate) in situations of relatively high soil pH is preferable to ammonium-based fertilisers (e.g., urea) to increase use efficiency (Mengel and Kirkby, 1987). Land application of biosolids or compost are known to be effective in restoring SOC levels and accelerating regenerative processes in similarly disturbed soils such as in reclamation o f mine sites (Ussiri and Lal, 2005;Silva et al, 2013;Pedrol et al, 2014). Build-up of SOC increases aggregate stability and soil structural development (Watts and Dexter, 1997;Bronick and Lal, 2005).…”

“…This was a surprise because there were no differences in macronutrients (N and P) and OM between this sediment and the sediment collected from the sites devoid of riparian vegetation. The available fraction of N, P and/or other nutrients, such as calcium and magnesium, which were not measured in our experiment, but affect Poaceae growth (Martina & Von Ende 2008;Pedrol et al 2014), may likely account for these differences. In contrast to nutrients, allelopathic substances released by riparian trees may negatively influence the herbaceous growth (P erez-Corona, de Las Heras & V azquez de Aldana 2013).…”

Shade provided by riparian plants and biotic resistance by macrophytes reduce the establishment of an invasive Poaceae

Running title:Riparian plants and invasion resistance Summary 1. Riparian corridors are habitats that are prone to invasion by non-native plants, but the shade provided by trees that grow in riparian zones may limit the success of invasive species. Accepted ArticleThis article is protected by copyright. All rights reserved. 2. In this investigation, we conducted three complementary experiments to test the effects of shade levels, along with sediment type and biotic resistance (and their interactions), on the establishment of a highly invasive grass (Urochloa arrecta (Hack. ex T. Durand & Schinz) Morrone & Zuloaga).3. This invasive grass presented higher growth rates in sediment collected under riparian vegetation than in sediment collected at sites devoid of vegetation. Shade levels similar to those found underneath riparian vegetation suppressed the establishment of U. arrecta. In addition, when native macrophytes were planted a priori (i.e. before U. arrecta propagules arrived), the establishment of the invasive species was suppressed, even at lower levels of shade. Thus, biotic resistance was sufficient to prevent the establishment of the invasive grass at low shade levels. Therefore, our results indicated that although the sediment from riparian zones may favour the establishment of U. arrecta, shading by trees and the presence of native macrophytes suppress it. Synthesis and applications.Our results indicate that the shade provided by riparian trees and biotic resistance by macrophytes are likely the factors that negatively affect the establishment of the invasive macrophyte U. arrecta. A recommendation for management arising from our results is that restoring riparian corridors to prevent invasion is most likely more efficient if native macrophytes are planted along with the trees. This would be an efficient strategy to prevent invasion by U. arrecta and other invasive Poaceae during the early stages of riparian vegetation regeneration.

“…Similar results were obtained for values of K ava (Figure 3c) and TN (Figure 3d). Several studies confirmed that the reclamation of bare lands significantly affected the status of soil nutrients [31,59], which could be related to various factors, such as the rate of fertilization, the kinds of applied fertilizers, the modes of plant configuration, the tillage practices, and the kind of land use after reclamation in particular [31,60,61]. Additionally, the reclamation age is another important factor regulating soil nutrients [31].…”

Assessment of Soil Redistribution Following Land Rehabilitation with an Apple Orchard in Hilly Regions of Central Iran

et al. 2022

This study was executed to explore soil redistribution and soil quality changes induced by land degradation and then rehabilitation by orchard plantation in different slope positions in a semi-arid region in central Iran. A total of 72 surface soil samples (0–30 cm) were collected from three land uses (natural rangelands, dryland farming, and apple orchards) in four slope positions (shoulder, backslope, footslope, and toeslope). The soil physicochemical properties and magnetic parameters were measured, and soil redistribution was determined in the selected soil samples using the 137Cs technique. The results showed that rangeland degradation and, subsequently, rainfed cultivation, led to a significant decline in the soil quality indicators, such as soil organic matter (SOM), total nitrogen (TN), available potassium (Kava), and available phosphorous (Pava), thus incurring further soil loss, as determined by the 137Cs technique. Conversely, the conversion and rehabilitation of drylands to apple orchards cultivated on the contour terraces improved soil quality significantly and decreased soil loss (p < 0.05) and soil quality grade (p < 0.01). Additionally, the findings indicated that slope positions relative to land use change had a reasonable impact on the variability of soil properties and soil loss and deposition. The results of 137Cs analysis showed that the drylands had the highest soil loss (185.3 t ha−1 yr−1) and maximum sedimentation (182. 5 t ha−1 yr−1) in the shoulder and footslope positions, respectively. The random forest model applied between 137Cs inventory and soil properties indicated that calcium carbonate equivalent (CCE), TN, Pava, Kava, and bulk density (ρb) could explain 75% of the total variability in 137Cs inventory with high R2 (0.94) and low RMSE (111.29). Magnetic measurements have shown great potential as a cost-effective and fast method for assessing soil redistribution in hilly regions, as confirmed by the findings of the 137Cs analysis, which agreed well with the magnetic susceptibility at low frequency (χlf). Overall, the results confirmed that restoring abandoned dryland by orchard cultivation may improve soil quality and diminish soil loss in the semi-arid region of Iran. However, further research is required to assess other aspects of the ecosystem affected by this restoration.
