Summary Moisture content and bulk density largely characterize physical and mechanical soil status and behaviour. A nondestructive determination of these soil properties is essential. Time domain reflectometry (TDR), although widely accepted for dete

A method is described that allows manipulation of soil structure as a variable in microcosm experiments while leaving other characteristics intact. The basic steps in the method are: (1) homogenization of the soil by sieving; (2) partial sterilizatio

The state of compactness of the arable soil layer changes during the growing season as a result of tillage and traction. The aim of this study was to assess and predict some soil mechanical and physical properties governing machine performance and cr

In a 2 year field experiment on a marine sandy loam soil, a typic fluvaquent, a roller was used to simulate current and possible future running gear. Loading the soil with variable weight on the roller was used to obtain a well defined treatment and

A new approach in defining the range of soil structure for optimal maize production is proposed. The effect of different degrees of compaction of ploughed sandy soils on soil aeration and mechanical impedance and on root and shoot growth of maize was

The imbibition of corn seeds ( Zea mays L.) was examined in a sandy soil compacted to simulate the effect that might be expected from pressure wheels behind a planting machine. Water uptake was found to be exponential and to be the only factor contri

Tensile strength of soil aggregates can be calculated from their crushing forces provided that the aggregate diameters are known. Three simple types of apparatus are described with which it is possible to measure the crushing forces of soil aggregate

The mechanical properties of remoulded samples of eight soils from the IJsselmeer polders were investigated. The Atterberg (Plastic and Liquid) Limits were positively correlated with the soil clay content, but were not significantly correlated with t

Aggregates were collected from the arable layer at eight sites in the IJsselmeer polders. The compositions of the soils were determined, and measurements were made of porosities, tensile strengths and water stabilities of undisturbed aggregates. Poro
