“…Other studies showed that the soil C:N ratio was inversely proportional to the decomposition rate of organic matter, and soil with a low C:N ratio has a faster mineralization rate (Cleveland & Liptzin, 2007;Wang & Yu, 2008), indicating that the soil C accumulation, organic matter decomposition and mineralization rate of the Ziwuling forest area would be faster than average. The C:N ratio in the soil also remained remarkably stable along the process of vegetation restoration, which is in line with the results reported for secondary forests worldwide (Yang & Luo, 2011;Zinn, Marrenjo & Silva, 2018). This is due to C and N, as structural components, have relatively fixed ratios in the process of accumulation and consumption (Cleveland & Liptzin, 2007).…”

“…This is due to C and N, as structural components, have relatively fixed ratios in the process of accumulation and consumption (Cleveland & Liptzin, 2007). Zinn, Marrenjo & Silva (2018) also discovered that soil C:N ratios are unresponsive to land use change. Furthermore, soil C:N ratios were stable across the soil profile across different vegetation types, which is consistent with previous reports (Tian et al, 2010;Wang et al, 2014).…”

“…Soil nutrient concentrations generally undergo dynamic changes over time, and these changes directly influence elemental nutrient stoichiometry (Fan et al, 2015;Ma et al, 2019;Wang et al, 2014). Many studies have found that vegetation restoration enhances soil nutrient status, improves microbial activity (Fan et al, 2015;Ren et al, 2016;Zinn, Marrenjo & Silva, 2018), and improves the C:N:P stoichiometry (Bai et al, 2019;Yang & Luo, 2011). However, other studies have shown that land use change decreases soil nutrient concentrations (Yang et al, 2012), and did not change soil C:N ratio (Zinn, Marrenjo & Silva, 2018).…”

Background Ecological stoichiometry (C:N:P ratios) in soil is an important indicator of the elemental balance in ecological interactions and processes. Long-term natural vegetation plays an important role in the accumulation and distribution of soil stoichiometry. However, information about the effects of long-term secondary forest succession on soil stoichiometry along a deep soil profile is still limited. Methods We selected Ziwuling secondary succession forest developed from farmland as the study area, investigated the concentrations and stoichiometry of soil organic carbon (SOC), total nitrogen (TN), and total phosphorus (TP) at a depth of 0–100 cm along a 90-year succession chronosequence, including farmland (control), grassland, shrub, early forest, and climax forest. Results SOC and TN concentrations significantly increased with increasing restoration age, whereas soil P concentration remained relatively stable across various successional stages. SOC and TN concentrations decreased with an increase in soil depth, exhibiting distinct soil nutrient “surface-aggregation” (high nutrients concentration in the top soil layer). The soil C:P and N:P ratios increased with an increase in restoration age, whereas the variation of the C:N ratio was small and relatively stable across vegetation succession. The nutrient limitation changed along with vegetation succession, transitioning from limited N in the earlier successional stages to limited P in the later successional stages. Conclusion Our results suggest that more nitrogen input should be applied to earlier succession stages, and more phosphorus input should be utilized in later succession stages in order to address limited availability of these elements. In general, natural vegetation restoration was an ecologically beneficial practice for the recovery of degraded soils in this area. The findings of this study strengthen our understanding of the changes of soil nutrient concentration and nutrient limitation after vegetation restoration, and provide a simple guideline for future vegetation restoration and reconstruction efforts on the Loess Plateau.

“…Proper soil coverage management can improve physical, chemical and biological soil properties (PELIZZA et al, 2009), which contributes to the production of fruit species (RAGOZO et al, 2006), thus deserving attention in agroecological production systems (GOH et al, 2000;ZINN et al, 2018). However, little is known about the effects of soil cover management in terms of weed occurrence and its competition with pear tree cultivation in Southern Brazil, and the efficiency of this practice in weed management and pear tree growth response may vary.…”

Soil cover management: initial development of pear trees hosui cultivar and its effects on soil and weeds

Soil management is a practice that influences the development of fruit trees. In this sense, the objective of this study was to evaluate the effect of different soil cover/mulching types on weed control and on the early development of pear trees Hosui cultvar. The experiment was conducted in two consecutive cycles: 2015/2016 and 2016/2017. Treatments consisted of the following soil covers in pear tree planting rows: natural cover, ryegrass straw intercropped with millet, pine sawdust, shading cover (70%), rice husk, Curauá fiber and weeding. Soil infestation by weeds was evaluated in the spring-summer period for two years, as well as the vegetative pear tree development (plant height and diameter and SPAD chlorophyll index). Managements using Curauá fiber and ryegrass straw + millet had the greatest suppression effects on weeds. The height and diameter of pear trees were smaller with natural cover and pine sawdust, while higher plant growth was observed with Curauá fiber and with weeding. Higher SPAD indexes was observed with Curauá fiber, weeding and ryegrass + millet. Curauá fiber also stood out for Fe and Mn leaf contents, while Zn contents were higher with ryegrass + millet and rice husk. Ryegrass straw + millet and rice husk can be highlighted for the chemical attributes of soil fertility and soil macrofauna indexes. It could be concluded that Curauá fiber and azevem + millet weed control weeds in the orchard, thus promoting better initial development of pear trees Hosui cultivar.
