Old Soil Organic Matter Has a Low Carbon:Nitrogen Ratio-A Global Meta-Analysis About <sup>14</sup>C and Soil Stoichiometry. [PDF]
Glob Chang BiolThis study demonstrates that old SOM has a low C:N ratio compared to young SOM, indicating that N is preferentially retained in soils compared to organic C. Furthermore, the study shows that the C:N ratio and the Δ14C are higher in forest and shrubland soils than in grassland and cropland soils throughout the soil profile. ABSTRACT Soil organic matter (

Mineral Stabilization of Soil Organic Sulfur at the Continental Scale. [PDF]
Glob Chang BiolThe conventional whole‐soil view treats soil organic sulfur (S) as a single bulk pool, obscuring the mechanisms governing its transformation, stabilization, and availability. Separating organic S into particulate organic sulfur (POS) and mineral‐associated organic sulfur (MAOS) distinguishes their contrasting sources, microbial transformations, and ...

An Interpretable Machine Learning Approach to Ecologically Characterize Soil Carbon and Structure From Multi-Kingdom Microbiome, Texture and Climate. [PDF]
Mol EcolABSTRACT Soil physical structure is a critical determinant of agricultural landscape resilience, yet standard pedotransfer functions estimate soil hydraulic and structural properties using static abiotic variables, often overlooking the biological mechanisms that actively organize soil structure.

Adsorption and release of soil P in andisols under organic and conventional vegetable farming system
Ilmu Pertanian (Agricultural Science), 2022 Phosphorous (P) is strongly adsorbed by soil components, such as soil organic matter and soil amorphous minerals in Andisols, which have been identified as an influential factor in adsorption and release of soil P.

Sains Tanah: Journal of Soil Science and Agroclimatology, 2023 The use of chemical fertilizer in rice fields contributes to increased global warming via enhanced emission of methane (CH4) into the atmosphere. Therefore, composting has been proposed to reduce methane emissions in the agricultural field.

Evaluating Zinc Nutrition In Perennial Ryegrass Grown In An Andisol
Geography, Environment, Sustainability, 2022 Zinc is an essential nutrient for humans, animals, and plants. Zinc uptake by crops is dictated by zinc availability in the soil, which in turn may be dictated, at least in part, by soil mineralogy.

Response of Arabica Coffee Cultivated on Andisols on Organic Matter Applications
Coffee and Cocoa Research Journal, 2013 Andisols are characterized by dominance of amorphous minerals which form strong and stable bonding with organic matter, therefore Andisols always contain high organic matter.

USE OF BIOLOGICAL ORGANIC FERTILIZERS AND PESTICIDES TO IMPROVE POTATO CULTIVATION IN SLOPE ANDISOLS
Biotropia: The Southeast Asian Journal of Tropical Biology, 2023 In the 1990s, potato yield in the Andisols of Dieng, Central Java, Indonesia, was approximately 30 t ha–1, but this value decreased rapidly to 12–15 t ha–1 in recent years.
