Carbon sequestration in clay and silt fractions of Brazilian soils under conventional and no-tillage systems

Scientia Agricola, 2014
The capacity of soils to sequestrate carbon (C) is mainly related to the formation of organo-mineral complexes. In this study, we investigated the influence of soil management systems on the C retention capacity of soil with an emphasis on the silt and ...

Theoretically predicting the solubility of polydisperse polymers using Flory–Huggins theory

JPhys Materials, 2023
Polydispersity affects physical properties of polymeric materials, such as solubility in solvents. Most biobased, synthetic, recycled, mixed, copolymerized, and self-assembled polymers vary in size and chemical structure.

The Crop Succession Systems Under No-Tillage Alters the Surface Layer Soil Carbon Stock and Stability

Agriculture
The main challenge of the no-tillage system (NTS) is to reconcile productivity, the maintenance of surface residues, and the stabilization of soil organic matter (SOM). To address this challenge, particularly in tropical regions, various cover crops have

Silicon isotope fractionation during abiotic silica precipitation at low temperatures: Inferences from flow-through experiments [PDF]

, 2014
Silicon isotopes have considerable potential as proxy for (near-) surface processes and environmental conditions. However, unambiguous interpretations of isotope signatures in natural silica deposits are often hampered by a lack of independent ...
