Impact of the Repeated Tractor Passes on Some Physical Properties of Silty Loam Soil
Soil compaction caused by machinery traffic in agriculture is a well recognised problem in many parts of the world as one of the most important factor responsible for soil physical degradation and has important consequences on crop production and environment (Soane and van Ouwerkerk, 1994; Keller and Arvidsson, 2004). It is estimated to be responsible for the degradation of an area of 68 millio...
متن کاملInterface Pressures of a Tractor Drive Tyre on Structured and Loose Soils
An 18 4R38 radial-ply tractor drive tyre was operated at 10% travel reduction, at three correctly inflated combinations of dynamic load and inflation pressures on a structured clay soil and at another combination of load and inflation pressure on a loose sandy loam and a loose clay loam soil. Soil–tyre interface pressures on the face of one lug and on an undertread region between two lugs were ...
متن کاملsimulation of tire-soil interaction using nonlinear finite element method with matlab
in this study, a simulation of tire–soil interaction model was considered with special view to two-dimensional (2-d) fem model of carcass. coefficients of mechanical behavior of silty-loam soil were accurately measured to obtain an effective simulation. the results of simulation which was implemented in matlab7, showed that the radial-ply tire had greater tractive efficiency than bias tire at t...
متن کاملTillage effects on soil organic carbon distribution and storage in a silt loam soil in Illinois
Interest in tillage impacts on sequestration of soil organic carbon (SOC) has increased greatly during recent years. The use of reduced and no-tillage (NT) practices generally increases the SOC concentration in surface few centimeters when compared to conventionally tilled soils. However, use of conservation tillage does not always result in increased SOC storage overall. The effects of sample ...
متن کاملAssessment of Crawler Tractor Effects on Soil Surface Properties
Skidding operations can cause considerable and wide spread soil disturbance. The objective of this study was to evaluate the effects of ground skidding operations on soil compaction, moisture content, and total porosity at different levels of slope and traffic frequency. Four levels of traffic intensity (3, 8, 13, and >13 passes of a Crawler Tractor Onezhets ? 110) and three levels of slope ( ...
