Evaluation Method of Total Organic Carbon Content in Shale Based on Stacking Algorithm Ensemble Learning

Cejing jishu
Total organic carbon content (TOC) is an important parameter for shale oil reservoir evaluation. However, traditional log evaluation methods for TOC have low accuracy and poor universality. Machine learning models have improved the prediction accuracy of

Mechanisms of the Effects of Carbon Source Addition on Carbon Transport and Sequestration in Purple Soil Sloping Farmland under Natural Rainfall

Shuitu Baochi Xuebao
[Objective] Degradation of purple soil and water loss is serious, and it is difficult to increase and sequester carbon in the soil. The aim of the study was to explore the impact of carbon source addition on carbon sequestration of purple soil sloping ...

Pattern of total organic carbon in sediments within the mangrove ecosystem

Frontiers in Marine Science
The sedimentary total organic carbon (TOC) in mangrove ecosystems plays an essential role in the global carbon storage. Nevertheless, little information is available about the pattern of TOC in sediments varying from bare and flat to those beneath ...

Millennial-aged pyrogenic carbon in high-latitude mineral soils

Communications Earth & Environment
Wildfires in the Arctic are producing pyrogenic carbon as product of incomplete biomass combustion. The storage and distribution of pyrogenic carbon in soils is poorly known, especially in carbon rich permafrost-affected mineral soils. Here, we extracted

Effect of Farming Systems on Soil Carbon Sequestration and Crop Yield of Paddy (Oryza sativa L.) in Irrigated Rice Field

Environment and Natural Resources Journal
Carbon sequestration is obtained from the total accumulation of the element in both soil and plants. The enhancement has the capacity to reduce greenhouse gas emissions and influence soil quality and fertility, thereby affecting plant biomass and crop ...
