Effects of Plum Plantation Ages on Soil Organic Carbon Mineralization in the Karst Rocky Desertification Ecosystem of Southwest China

open access: yes, 2019
Soil organic carbon (SOC) mineralization is closely related to carbon source or sink of terrestrial ecosystem. Understanding SOC mineralization under plum plantation is essential for improving our understanding of SOC responses to land-use change in ...

Deforestation And Rocky Desertification Processes In Gunung Sewu Karst Landscape (Proses Deforestasi dan Rocky Desertifcation di Landskap Karst Gunung Sewu) [PDF]

open access: yes, 2008
Kerapuhan suatu kawasan karst merupakan dasar terbentuknya rocky desertification, yaitu proses yang merubah kawasan karst yang sebelumnya ditutupi oleh vegetasi dan tanah, menjadi landskap batuan hampir tanpa vegetasi dan tanah (Yuan, 1991: 1).

Contribution of Litter and Root to Soil Nutrients in Different Rocky Desertification Grasslands in a Karst Area

open access: yesPlants
Litter and root decomposition is an important source of soil organic matter and nutrients. To ascertain the contribution of litter and root to natural grassland nutrients in rocky desertification areas, from March 2017 to January 2018, the continuous soil column method, collector method, and litter decomposition method were used to study the soil ...

A New Attempt to Estimate Underground Soil Leakage through High-Density, Fixed-Point Monitoring in a Typical Karst Rocky Desertification Region

open access: yesAgriculture
Understanding soil loss pathways in karst regions is crucial for erosion control. Combining high-density measurements of grid points with runoff plot monitoring, we attempt to use a new indirect method to study the characteristics of soil loss in karst ...

Rainfall water collection and irrigation via stone bud and karren on karst rocky desertification slopes: Application and benefit analysis

open access: yesAgricultural Water Management
Lack of surface water is a key factor leading to agricultural drought in karst regions and exacerbates the karst rocky desertification, which is characterized by high rate of exposed bedrock. With the characteristics of impermeability, runoff collection,

Evaluation of soil fertility in the succession of karst rocky desertification using principal component analysis

open access: yes, 2015
Expanding of karst rocky desertification (RD) area in southwestern China is strangling the sustainable development of local agricultural economy. It is important to evaluate the soil fertility at RD regions for the sustainable management of karst lands ...
