Soil behavior of shallow homogenous upper layer soil

Journal of Applied Science and Engineering, 2021
This study aims to examine the compaction nature of shallow homogeneous soil based on the results from confined and unconfined compression tests. A plate sinkage test is employed for the experiments. A big soil bin of diameter was used for the unconfined

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

Frontiers 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.

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

Acta 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]

Journal 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,

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

Journal 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.

MEASUREMENT OF SOIL REACTION FORCES BY A SINGLE FLAT WHEEL ON THE SLOPE SOIL BIN

INMATEH Agricultural Engineering, 2022
The ability of a cage wheel to climb slopes depends on the grip of the lug on the sloped soil. A lug wheel that sinks deeper will generate more force when climbing. This study aimed to measure the soil reaction force on a single flat lug wheel in the slope soil bin so that the optimal lug angle is obtained to enhance the ability of cage wheels to climb
