A method for soil compactibility determination

Evaluation of Shear Strength and Cone Penetration Resistance Behavior of Tropical Silt Loam Soil under Uni-Axial Compression

“…The models are largely nonlinear and they agree well with those reported by other researchers [6][7][8][9][10][11][12].…”

“…The ability to predict compaction is the first requirement for attaining control of compaction. Considerable research has been performed in attempts to develop soil compaction behaviour equations [6][7][8][9][10][11][12]. Others have also reported on effects of organic matter and tractor passes on compaction and yield of crops [13,14].…”

Soil and macro-pores under uniaxial compression. I. Mechanical stability of repacked soil and deformation of different types of macro-pores

“…Mechanical stability is used here as a measure for the maximum external load a soil can withstand without irreversible deformation. A useful stability criterion in agricultural soil mechanics is precompression stress (Kirby, 1991), which is determined from compression curves (void ratio vs. logarithm of applied normal stress) obtained by means of uniaxial compression tests (Koolen, 1974). Conceptually, precompression stress is the maximum stress a soil has been subjected to in the past under given conditions (Kirby, 1991).…”

Assessment of the Behaviour of Field Soils during Compression

“…Koolen, 11 Larson and Gupta, 12 Larson et al 13 and Seig 14 used confined compression tests to assess the compactability of agricultural soil. These tests, however, were carried out on air-dried and sieved soil which may have displayed very different compression characteristics from the original structured field soil.…”
