“…Palmer-Felgate et al (2009) determined that higher risk agricultural practices (intensive arable production and dairy and beef production) can lead either directly, or indirectly through increased inputs of fine sediment, to increased sediment P concentrations. Among pasture and croplands, Barral et al (2007) found that pasture soil presents a higher mean aggregate diameter and aggregate stability against mechanical agitation in water, as well as lower soil loss under simulated rainfall, so its contribution to the sediments may be similar to the contribution of cropped soils, in spite of the higher concentrations of the former.…”

Purpose The study of phosphorus (P) transfer from soils to rivers is a subject of interest as there is a clear relation between land use and water quality. P transfer in the soil/sediment system was evaluated by comparing the concentrations of total (P T ) and bioavailable P (P A ). Materials and methods Phosphorus concentrations were measured in three different compartments following the natural transport route in a basin: soils, suspended and riverbed sediments. Soils were sampled from five different types of land cover: cropped land, forest, pasture, river banks and road taluses (roadside open earthen ditches). Samples were taken from two different sub-basins: the Grande and the upper Anllóns sub-basins. Results and discussion The highest concentrations of P were found in the suspended sediments, followed by the riverbed sediments and the soils. The cropped and pasture soils contained the highest amounts of P. The P A /P ratio was very low in the soils (<0.3), but was significantly higher in the sediments, particularly in the suspended sediments (0.67). The concentration of P A was also significantly higher in the suspended sediments and riverbed sediments than in the river basin soils, with concentration factors of 300% for P and 2,600% for P A , either in suspended and bed sediments being slightly higher in the suspended than in the bed sediments , which suggests the potential environmental risk of P transfer to the river courses via soil. Conclusions Comprehensive studies involving P transfer across soils-suspended sediments-bed sediments are scarce, highlighting the innovative nature of the present study. The results obtained will allow the evaluation of the impact of different types of land use on the sustainability of the aquatic ecosystem at a catchment scale.

“…An increase in vegetation cover increases the source of soil organic matter, this being the main bonding material forming soil aggregate structure (Yu et al, 2017). Therefore, the cohesive effect of soil particles with an anchor frame beam is stronger than rimless slope, and more stable aggregates can be formed (Barral et al, 2007). Our results…”

“…Analysis of soil structural characteristics from the number, spatial distribution, fractal dimension (D m ) of PSD, water movement features, and soil aggregate stability have been previously undertaken (Asano & Wagai, 2014;Baveye, 2006;Pagliai, Vignozzi, & Pellegrini, 2004;Young & Crawford, 2004;Young, Crawford, & Rappoldt, 2001). As soil bulk density, porosity, moisture, organic matter content can also affect the soil nutrients, water cycle, formation, and stability of soil aggregates, affecting the growth status of plants, these factors therefore have a significant influence on chemical and biological processes, and they are important indices for evaluating soil quality (Barral, Bujan, Devesa, Iglesias, & Velasco-Molina, 2007;Dexter, 2004;Hayashi, Ken'ichirou, & Mizuyama, 2006;Kaisermann, Maron, Beaumelle, & Lata, 2015).…”

Cut-slope restoration technologies commonly used in southwest China mainly include using simple outside soil spray seeding (OSSS) techniques, or OSSS combined with an anchor frame beam. Artificial soil used in OSSS can establish a soil layer suitable for revegetation; the addition of an anchor frame beam not only fixes soil and shallow rock, it also acts to strengthen deep rock. However, there have been few studies on the effects of frame beams on artificial soil structural characteristics on railway cutslopes. In order to evaluate the effects of different frame beams on artificial soil structure, soil samples from a natural slope (NS) and three cut-slopes restored using OSSS with various frame beams (AS, arched slope; DS, diamond slope; and RS, rimless slope) were analyzed. Soil structural characteristics analyzed include particle-size percentage and cumulative distribution curve of dry-sieving and wet-sieving aggregates, structural failure rate, water stability factor, soil particle size distribution (PSD), bias and peak convex coefficients, fractal dimension of PSD (D m ), and fundamental properties. Our results indicate that structural failure rate, water stability factor, fractal dimension of PSD, soil bulk density, total porosity, moisture content, and organic matter are significantly affected by the use of different frame beams. In addition, a difference in wetsieving soil aggregates content, PSD, clay and sand particle contents, D m, and the area difference ΔS of cumulative distribution between AS and DS was evident. Overall, soil structure in cut-slopes using a diamond frame anchor beam recorded the best levels of recovery after 8 years of ecological restoration.

“…In addition to stump removal, the long-term effect of disking nine times in the first 3 years after planting likely contributed to the increased bulk density in the upper 10 cm of Depth ( soil. When soils are cultivated year after year, they become more dense than similar soils that remain as undisturbed prairie (Mudgal et al 2010) or pasture land (Barral et al 2007). It is notable that these effects could persist for 49 years in the present study.…”

Impacts of pine species, stump removal, cultivation, and fertilization on soil properties half a century after planting

To better understand the long-term effects of species selection and forest management practices on soil quality and soil C retention, we analyzed soil samples from an experimental planting of loblolly (Pinus taeda L.), longleaf (Pinus palustris Mill.), and slash (Pinus elliottii Engelm.) pines under different management intensities in Mississippi. The treatments included stump removal and cultivation (CULT), a one-time application of fertilizer combined with stump removal and cultivation (CULT+F), and a control (CON). After 49 years, pine species had no significant effect on any soil physical or chemical parameter examined, despite species differences in basal area. CULT exhibited significantly higher soil bulk density and lower soil C and soil N than CON and CULT+F in the upper 10 cm of soil. Stump removal is not a common practice in southern pine silviculture today; however, as demand for bioenergy fuels or feedstocks increases, more complete biomass utilization will be considered. Residual stumps play an important role in soil nutrient and C retention in pine plantations. Our results show that stump removal can lead to reduced soil C (-21%) and soil N (-35%) compared with controls, although it is possible to mitigate nutrient losses on poor sites with fertilization.Résumé : Dans le but de mieux comprendre les effets à long terme du choix des espèces et des pratiques d'aménagement forestier sur la qualité du sol et la rétention du C, nous avons analysé des échantillons de sol provenant de plantations expérimentales de pin à encens (Pinus taeda L.), de pin des marais (Pinus palustris Mill.) et de pin d'Elliott (Pinus elliottii Engelm.) soumises à différentes intensités d'aménagement au Mississippi. Les traitements incluaient l'enlèvement des souches et des pratiques culturales (CULT), une application unique de fertilisant combinée à l'enlèvement des souches et à des pratiques culturales (CULT+F) et un traitement témoin (CON). Après 49 ans, les espèces de pin n'avaient pas d'effet significatif sur aucun des paramètres physiques ou chimiques du sol qui ont été étudiés malgré les différences de surface terrière entre les espèces. Dans les premiers 10 cm de sol, la densité apparente du sol était plus grande et la teneur en C et N du sol était plus faible dans le traitement CULT que dans les traitements CON et CULT+F. L'enlèvement des souches n'est pas une pratique courante de la sylviculture actuelle des pins du sud. Cependant, à mesure que la demande pour la biodiversité et les matières premières augmente, une utilisation plus complète de la biomasse sera envisagée. Les souches résiduelles jouent un rôle important dans la rétention de C et des nutriments dans le sol des plantations de pin. Nos résultats montrent que l'enlèvement des souches peut entraîner une diminution de C (-21 %) et de N (-35 %) dans le sol comparativement au traitement témoin bien qu'il soit possible d'atténuer les pertes de nutriments dans les stations pauvres par la fertilisation.[Traduit par la Rédaction]
