Climatic and Edaphic Drivers of Soil Organic Carbon and Pyrogenic Carbon Stocks Across Elevation and Disturbance Gradients in Colombian Andean Forests. [PDF]

Glob Chang Biol
This study examined soil organic carbon (SOC) and pyrogenic carbon (PyC) stocks in tropical Andean soils across elevation and disturbance gradients in Colombia. SOC stocks to 100 cm depth averaged 433.10 Mg C ha−1 while PyC was 34.13 Mg C ha−1. Key drivers of PyC stocks include soil clay (%), mean annual precipitation (PA), pH, Ca, and NDVI, which ...

Storage Potential of Soil Functional Carbon Fractions in the World's Largest Plantations. [PDF]

Adv Sci (Weinh)
Climate warming and drying increase the loss of mineral‐associated and particulate organic carbon during the conversion of natural forests to plantations. Based on a survey of the world's largest plantations, the study quantifies the soil carbon deficit in plantations and assesses benchmarks and targets for functional soil organic carbon, highlighting ...

Determining the optimal application rate of chicken manure for agricultural land through Phosphorus sorption-desorption analyses in Andisols of Wonokitri, East Java, Indonesia

Sains Tanah: Journal of Soil Science and Agroclimatology, 2023
Phosphorus (P) is a macro-essential element extensively used in agricultural production. Andisols, commonly found in Indonesia, serve as agricultural areas with high, excessive, and continuous organic matter input. However, the propensity of the soil for

Distribution of Available Silicon of Volcanic Ash Soils in Jeju Island

Applied and Environmental Soil Science, 2019
In soils, dissolved silicon (Si) is adsorbed onto soil particles or is leached into groundwater through the soil profile. Andisols may play an important role in contributing to high dissolved Si concentrations in groundwater on Jeju Island, Korea.
