Assessment of selected soil parameters in a long-term Western Canadian organic field experiment [PDF]

open access: yes, 2007
A long-term field study was used to compare soil nitrogen and phosphorous status, and soil aggregate stability in organic and conventional cropping systems. Two rotations were tested: a grain only and a grain-alfalfa hay rotation.

The aggregate stability of the soil in respect to the uniform aggregate stability indicator

open access: yesActa Agraria Debreceniensis, 2007
Soil structure and its quality are fundamental properties because they control many processes in soils. Tillage, crop and other factors influence soil structure. Efficient protection of it needs indication of changes in soil structure. A new Normalized Stability Index proposed by Six et al.

In Situ Constructed Magnetic Core‐Shell Hydrogen‐Bonded Organic Framework‐on‐Metal–Organic Framework Structure: an Efficient Catalyst for Peroxymonosulfate Activation

open access: yesAdvanced Functional Materials, EarlyView.
In this work, a magnetic core‐shell catalyst (HOF‐on‐Fe3O4/ZIF‐67) is successfully synthesized, consisting of a metal–organic framework (ZIF‐67) with magnetic Fe3O4 as the core and a porous hydrogen‐bonded organic framework (HOF) as the shell. The catalyst efficiently activated peroxymonosulfate, resulting in rapid and effective removal of water ...

Cover crop residues effect on soil structural stability and phosphatase activity

open access: yesActa Agriculturae Scandinavica. Section B, Soil and Plant Science, 2021
Good soil aggregate stability and soil enzyme activity are strictly necessary for the proliferation of plants growth and soil resistance against erosion. In this study, the goal was to investigate the effect of different cover crops on the soil aggregate

Aggregation characteristics and maturity of Peak District soils [PDF]

open access: yes, 1969
Soil aggregation and aggregate stability are fundamental factors in determination of soil erodibility. The aggregation characteristics of soils in a region of high erosion potential are measured, and controlling factors examined.

Carbohydrates in hot water extracts of soil aggregates as affected by long-term management [PDF]

open access: yes, 2002
Microbial carbohydrates are immediate by-products of microbial metabolism and play an important role in the formation and stabilization of soil structure.

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

open access: yesAdvanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

Responses of soil aggregate characteristics to grazing intensity differ between topsoil and subsoil in a typical steppe

open access: yesFrontiers in Environmental Science
Soil aggregates are vital to soil structure, influencing grassland ecosystem health and sustainability. As a dominant land use in grasslands, grazing acts as a key driver of ecosystem structure and function, yet the responses of aggregate size ...

Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance

open access: yesAdvanced Functional Materials, EarlyView.
A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation

Assessing soil aggregate stability by measuring light transmission decrease during aggregate disintegration

open access: yesSoil and Water Research
Advancements in technology have recently enabled to assess soil aggregate stability (SAS) using digital devices. To address the need for a faster and more efficient method of measuring SAS, we have developed a simple yet effective approach using a ...
