Enzymatic activity of air-dried and water-stable aggregates of soils under different land use

Бюллетень Почвенного института им. В.В. Докучаева, 2016
Under study were the levels of enzymatic (peroxidase, polyphenoloxidase and catalase) activity in air-dry structural particles 1-2 mm thick and water- stable aggregates extracted from the samples of soddy-podzolic soils (under forest and in crop) and ...

Response of soil organic carbon and water-stable aggregates to different biochar treatments including nitrogen fertilization

Journal of Hydrology and Hydromechanics, 2018
Recent studies show that biochar improves physical properties of soils and contributes to the carbon sequestration. In contrast to most other studies on biochar, the present study comprise a long-term field experiment with a special focus on the ...

Centrifugation-Induced Stable Colloidal Silver Nanoparticle Aggregates for Reproducible Surface-Enhanced Raman Scattering Detection

Biosensors
Colloidal noble metal nanoparticle aggregates have demonstrated significant advantages in surface-enhanced Raman scattering (SERS) analysis, particularly for online detection, due to their excellent optical properties, spatial homogeneity, and fluidic ...

Physical and chemical stabilization of soil organic matter in cropland ecosystems under rice–wheat, maize–wheat and cotton–wheat cropping systems in northwestern India

Carbon Management, 2021
This article examines the impact of rice–wheat, maize–wheat and cotton–wheat cropping systems on total (TOC), labile and stable organic carbon (C) pools, aggregate stability and distribution of organic C in different size aggregates and the mineral ...

Semantics and complexity of recursive aggregates in answer set programming [PDF]

, 2011
The addition of aggregates has been one of the most relevant enhancements to the language of answer set programming (ASP). They strengthen the modelling power of ASP in terms of natural and concise problem representations.

Managing soil organic matter through biochar application and varying levels of N fertilisation increases the rate of water-stable aggregates formation

Journal of Hydrology and Hydromechanics, 2023
The formation of soil aggregates, including water-stable aggregates, is linked to soil organic matter (SOM). Biochar (B) is carbon-rich, which, in addition to storing carbon in a stable form for many years, has important benefits for soils and plants ...

Rewriting recursive aggregates in answer set programming: back to monotonicity [PDF]

, 2015
Aggregation functions are widely used in answer set programming for representing and reasoning on knowledge involving sets of objects collectively. Current implementations simplify the structure of programs in order to optimize the overall performance ...

Stability of soil aggregates and their ability of carbon sequestration

Soil and Water Research, 2014
One of the most important binding agents for forming stable aggregates is a soil organic matter (SOM), which can be retained in various size fractions of aggregates. If aggregates are water-resistant, they retain more carbon.
