Ecological and Genomic Attributes of Novel Bacterial Taxa That Thrive in Subsurface Soil Horizons. [PDF]

open access: yes, 2019
While most bacterial and archaeal taxa living in surface soils remain undescribed, this problem is exacerbated in deeper soils, owing to the unique oligotrophic conditions found in the subsurface.

Soil pH Determines the Spatial Distribution, Assembly Processes, and Co-existence Networks of Microeukaryotic Community in Wheat Fields of the North China Plain

open access: yesFrontiers in Microbiology, 2022
Soil microeukaryotes play a pivotal role in soil nutrient cycling and crop growth in agroecosystems. However, knowledge of microeukaryotic community distribution patterns, assembly processes, and co-existence networks is greatly limited.

VIII.—The Soils and Vegetation of the Bin and Clashindarroch Forests

open access: yesTransactions of the Royal Society of Edinburgh, 1941
The Bin and Clashindarroch Forests lie some 40 miles to the north-west of Aberdeen. Clashindarroch Forest, the larger of the two, stretches from the Rhynie-Cabrach road in the south almost to the Huntly–Glass road in the north. The Bogie valley in the east forms another rough boundary for the hill mass that the forest occupies.

A new hoe share design for weed control: measurements of soil movement and draught forces during operation

open access: yesActa Agriculturae Scandinavica. Section B, Soil and Plant Science, 2018
This research introduces a new share design (L-share) that reduces the undesired random soil movement, providing a more controlled disturbance of the upper soil layer.

Prediction of Rut Depth in Soil Caused by Wheels Using Artificial Neural Networks [PDF]

open access: yesJournal of Agricultural Machinery
Introduction The formation of ruts induced by vehicle traffic poses a significant challenge for agricultural soils due to soil compaction both at the surface and deeper layers. This phenomenon compromises vehicle performance increases energy consumption,

Self-Excited-Resonance of Soil-Engaging Surface Spectrum: A New Method of Soil Cutting Resistance Reduction

open access: yesAgriculture, 2023
In this study we explored the methods and effects of spectral resistance reduction for soil-engaging surface of self-excited resonant bulldozing plates with a plane base on the basis of resonance effects.

A Finite Element Model of Soil-Stress Probe Interaction under a Moving Rigid Wheel [PDF]

open access: yesJournal of Agricultural Machinery
Machinery traffic is associated with the application of stress onto the soil surface and is the main reason for agricultural soil compaction. Currently, probes are used for studying the stress propagation in soil and measuring soil stress.
