“…In forest ecosystems, understory vegetation can be an important factor impacting soil C and N processes [ 9 ] as has been documented by previous studies [ 10 , 11 ]. While understory vegetation represents only a small portion of forest biomass, it plays an important role in maintaining biodiversity, ecosystem stability, and sustainable productivity of forest ecosystems [ 12 ].…”

Understory vegetation plays a vital role in regulating soil carbon (C) and nitrogen (N) characteristics due to differences in plant functional traits. Different understory vegetation types have been reported following aerial seeding. While aerial seeding is common in areas with serious soil erosion, few studies have been conducted to investigate changes in soil C and N cycling as affected by understory vegetation in aerially seeded plantations. Here, we studied soil C and N characteristics under two naturally formed understory vegetation types (Dicranopteris and graminoid) in aerially seeded Pinus massoniana Lamb plantations. Across the two studied understory vegetation types, soil organic C was significantly correlated with all measured soil N variables, including total N, available N, microbial biomass N and water-soluble organic N, while microbial biomass C was correlated with all measured variables except soil organic C. Dicranopteris and graminoid differed in their effects on soil C and N process. Except water-soluble organic C, all the other C and N variables were higher in soils with graminoids. The higher levels of soil organic C, microbial biomass C, total N, available N, microbial biomass N and water-soluble organic N were consistent with the higher litter and root quality (C/N) of graminoid vegetation compared to Dicranopteris. Changes in soil C and N cycles might be impacted by understory vegetation types via differences in litter or root quality.

“…Therefore, soil physicochemical properties are important to determine site-specific management (Yao et al, 2014). Sohng, Singhakumara, & Ashton (2017) suggested that land use change in tropical forest area into some types of plantation changed some Copyright © 2018 Universitas Brawijaya soil properties such as soil bulk density (BD), N, and C stocks. Soil nitrogen percentage decreased from native grassland to farmland as well as to artificial grassland (Xue, Cheng, & An, 2013).…”

This research was aimed to study soil physico-chemical properties at four slope positions under oil palm plantation in Dharmasraya, West Sumatra, Indonesia. Soils were sampled at 0-20 cm soil depth from 4 different slope positions (upper, middle, lower slope, and the bottom or flat area). The parameters analyzed were soil texture, SOM, bulk density, total pore, hydraulic conductivity, soil water potential (physical characteristics) as well as soil pH, CEC, Al-exchangeable, basic cations (Ca, Mg, K), N, and P (chemical characteristics). The results showed that the bottom area had better soil physicochemical properties than the others. SOM increased by 33%, total pore by 19%, void ratio by 47%, plant available water (PAW) by 28%, soil pH-H 2 O by 41%, CEC by 171 %, total-N by 170 %, and P-potential by 114 %, in contrast, soil BD and exchangeable-Al were lower (20 % and 96 %, respectively) in the bottom than in the sloping land. The middle slope had the poorest soil physico-chemical properties after 26 years of forest conversion into oil palm plantation. All sites had clay texture, the clay content increased (R 2 =0.93) by lowering slope position, and so did SOM content (R 2 =0.86), soil CEC (R 2 =0.93), and soil total-N values (R 2 =0.76).

“…Unfortunately, there is no data on the content of carbon for previous years, which is why it is not possible to determine the decrease in the capacity of storing carbon. The effect of land use change over the capacity of capturing or sequestrating carbon has already been reported in the literature (Assefa et al 2017;Sohng et al 2017) and the concentration of COS has also been evaluated according to the different land uses. The total SOC stored in the analysed soils of Ramsar site is 9.67 × 10 5 t during one year period, calculated by adding the SOC values in each sampling point; approximately, 40% of the total is stored by IP, followed by the OF/sSV, RA and HS (24%, 23%…”

The soil organic carbon (SOC) was determined in 40 sites at two depths (0-10 and 10-20 cm) for different uses of soil during one year (February 2014-February 2015). The total SOC stored in the analysed soil from the Ramsar site was 9,67×10 5 t, from which 40% was stored in induced pasture, followed by the red oak forest with shrubbery secondary vegetation, rain-fed agriculture and human settlements (24%, 23%, and 13%, respectively); the last was evaluated to determine how the proximity of the city impacts the SOC. The SOC concentrations present significant differences with respect to soil depth (p = 0.0) and land use (p = 0.0). The temporal distribution maps showed that SOC did not present significant variations in the short-term. A relation between SOC and bulk density was found (r = −0.654, p = 0.00), with respect to other physicochemical properties. Moreover, a significant relation between SOC and stored total nitrogen (r = 0.585; p = 0.00) was found. This work represents the first study that analyses the current condition of the soils in the Ramsar site 'Presa ManuelÁvila Camacho'.
