Effects of no-tillage and subsoil loosening on soil physical properties and crop performance : a thesis presented in partial fulfilment of the requirements for the degree of Master of Applied Science in Soil Science at Massey University [PDF]

open access: yes, 1998
Much of New Zealand's lowland agriculture integrates animal and crop production on poorly drained, easily compacted soils. Over the years, conventional cultivation has given rise to degraded soil structure on many farms.

Soil analyses and evaluations at the impact dynamics research facility for two full-scale aircraft crash tests [PDF]

open access: yes
The aircraft structural crash behavior and occupant survivability for aircraft crashes on a soil surface was studied. The results of placement, compaction, and maintenance of two soil test beds are presented. The crators formed by the aircraft after each

Soil mechanics on the Moon, Mars, and Mulberry [PDF]

open access: yes
From a soil mechanics point of view, the Moon is a relatively simple place. Without any water, organics, or clay minerals, the geotechnical properties of the lunar soil are confined to a fairly limited range.

The effect of organic management on soil quality indicators [PDF]

open access: yes, 2002
This report was presented at the UK Organic Research 2002 Conference. A range of physical, biological and chemical parameters were measured in organic soil that had been managed in different ways and in a conventional control.

Development of a Sinkhole Raveling Chart Based on Cone Penetration Test (CPT) Data [PDF]

open access: yes, 2018
Naturally occurring sinkholes in Florida are formed when the soluble limestone bedrock weathers and creates cavities at its interface with the overburden finer-grained soils. The overburden soil then erodes into the limestone fissures, thus weakening the
