“…The clay content in tea fields increased with the increase in elevation at both soil depths. In contrast to our results, a study conducted by Yuksek et al [26] in the same region determined that the clay content of soils decreased with increasing elevation in tea fields. This difference might be due to the differences in the parent material, land use history, and soil texture properties.…”

“…Tekeş and Cürebal [22] reported that land use varies with elevation, with agriculture and settlement more common at lower elevations, while forest and grassland areas are more common at higher elevations. There have been few studies performed in the Eastern Black Sea region on changes in soil properties with land use, elevation, and soil depth [5,8,9,[23][24][25][26][27][28]. Thus, there are still gaps in the research in terms of how soil properties change in tea, hazelnut, forest, and grassland sites with elevation in this region of Turkiye.…”

Knowledge of soil properties such as texture, bulk density, organic matter, soil reaction, soil electrical conductivity, and soil erodibility factor is fundamental to the sustainable management of soil resources. This study aimed to determine the changes in certain soil properties including texture, bulk density, organic matter, pH, electrical conductivity, and soil erodibility factor with different land uses, elevation zones and soil depths in the Arhavi Sub-basin, Artvin, Turkiye. For these purposes, a total of 618 soil samples (309 disturbed and 309 undisturbed) were taken from 155 sampling points located in areas with different land uses, including tea (33 sampling points), hazelnut (33 sampling points), forest (67 sampling points), and grassland (22 sampling points). The results of the statistical analysis revealed that the soils at depths of 0–15 cm and 15–30 cm showed significant differences according to the land use in terms of sand, clay, silt, bulk density, organic matter, and pH. There were significant positive correlations between elevation and soil bulk density (r = 0.495) at a soil depth of 0–15 cm in the tea areas. In the grassland areas, there were significant positive correlations between elevation and silt, bulk density, and the soil erodibility factor (r = 0.485, r = 0.794, and r = 0.442, respectively) at depths of 0–15 cm, and significant positive correlations between elevation and both silt and bulk density (r = 0.468 and r = 0.691, respectively) at depths of 15–30 cm. Similarly, there were significant positive correlations between elevation and both sand and organic matter at soil depths of 0–15 cm and 15–30 cm (sand: r = 0.351 and r = 0.638, respectively; organic matter: r = 0.277 and r = 0.587, respectively). On the other hand, significant negative correlations were found between elevation and silt, bulk density, pH, and the soil erodibility factor at depths of 0–15 cm and 15–30 cm (silt: r = −0.400 and r = −0.461, respectively; bulk density: r = −0.593 and r = −0.545, respectively; pH: r = −0.354 and r = −0.309, respectively; soil erodibility factor: r = −0.443 and r = −520, respectively). Soil acidity was found to be the most important problem threatening soil fertility in all land uses. The use of soil acidity-increasing fertilizers, such as ammonium sulfate, in tea gardens in the region should be eliminated to protect the fertility of soils in the future. The knowledge that this study provides might help farmers and foresters in the region in the proper management and fertilization of their lands. Moreover, this study will provide data to future studies related to soil acidification, soil erosion, and land use that are planned for the Arhavi Sub-basin.

“…There are many factors that effects the soil physicochemical properties like elevation, parent material or geological formation, human activities or interferences and climatic characteristics [83]. In these study the prime factors affecting the soil properties are parent material, heavy rainfall, weathering processes, high aluminum (Al), iron and manganese contents [21] and the large number of base cations leaching from soil [57].…”

The effects of tea plantations upon soil are of great concern in the context of monoculture crops due to their increasing demand resulting in the expansion of tea growing areas. Therefore, this study was conducted to understand the soil’s Physico-chemical properties, soil nutrient concentrations, and stoichiometry in major tea-growing areas of India and China. For this study Meta-analysis approach was used to examine the difference between the two countries. Soil pH tends to be more acidic in Chinese soil (CS) than in Indian Soil (IS), soil Bulk Density (BD) was higher in CS with low soil Total Porosity (TP). Whereas the soil texture in CS was fine texture with Silt Clay while IS texture was coarse with sandy clay loam. Soil Carbon (C) showed no significant difference; while Nitrogen (N) concentration showed a significant difference only at the top layer with a higher concentration in IS. Soil Phosphorus (P) and Potassium (K) concentration were significantly higher CS than IS at all soil depths. The C: N ratio in both the countries was below 10 showing the accumulation of organic matter is low whilst the C: P ratio showed net mineralization of nutrients in both the countries. The N: P ratio represented N limitation in CS while P limitations in IS. The comparison of soil physical-chemical properties between India and China revealed the distinct differences between the tea plantation soils in both of these countries. Except for C concentration C: P, N: K, and P: K ratio all the properties are deemed to be different. Our results suggest that a balanced fertilizer application and these N and P limitations in tea growing soil of these two countries should be paid more attention to.

“…Only a few studies have specifically examined and evaluated SOC and N stock within the context of tea plantations. Some studies have explored the impact of converting forests into tea plantations (e.g., Chen et al 2016 ; Chiti et al 2018 ; Sohng et al 2017 ; Yüksek and Yüksek 2021 ; Yulnafatmawita et al 2020 ). The reversion of tea plantations to forests or the implementation of different management practices has rarely been investigated in literature.…”

Background The restoration of conventional tea plantations and the adoption of organic farming practices could impact soil organic carbon (SOC) and nitrogen (N) stocks. This study investigated the soil properties, SOC and N contents and stocks, and their vertical distributions of a secondary forest restored from an abandoned conventional tea plantation and a converted organic tea plantation. An adjacent conventional tea plantation employing similar intermediate farming served as a comparison. Results Within a 50-cm depth, the secondary forest exhibited a higher SOC stock of 115.53 ± 7.23 Mg C ha− 1 compared to 92.1 ± 8.54 Mg C ha− 1 for the conventional tea plantation. No significant differences in N stocks were seen between the two land uses. Significantly high SOC and N contents and stocks were found in the 0–10 cm layer of the secondary forest compared to the conventional tea plantation. No significant disparities in SOC and N stocks were found between the conventional and organic tea plantations within the 50 cm depth (92.1 ± 8.54 Mg C ha− 1 and 10.06 ± 1.01 Mg N ha− 1 vs. 97.47 ± 1.53 Mg C ha− 1 and 9.70 ± 0.10 Mg N ha− 1). However, higher levels of SOC and N contents and stocks were observed at a depth of 10 cm in the conventional tea plantation and below 10 cm in the organic tea plantation. Conclusions The C and N inputs derived from high litter production at the top soil strongly contributed to higher SOC and N contents and stocks in the secondary forest. The application of soybean amendments in the conventional tea plantation and the longer tea plantation age of the organic tea plantation influenced their distribution of SOC and N contents and stocks, respectively. Reverting a conventional tea plantation into a secondary forest contributed to C recovery and reaccumulation. The conventional tea plantation, employing similar intermediate farming practices, increased SOC and N contents and stocks in the surface soil compared to the organic tea plantation. However, adopting organic farming did not significantly increase SOC stocks compared to the conventional tea plantation.
