Abstract

The effects of cropping sequences on the strength and porosity
of the Portneuf silt loam soil were studied in south-central
Idaho under normal field conditions. Undisturbed soil cores
were collected from the surface 20 cm of seven fields with
cropping histories ranging from continuous pasture to continuous
beans (Phaseolus vulgaris L.). The soil in all fields was
a uniform silt loam developed under arid conditions. The pore
size distribution and soil hardness were measured on the undisturbed
cores as well as on bulk samples collected from each
site. The results indicated that both the pore size distribution
and the hardness are rather independent of cropping history.
While both these parameters can be changed by mechanical
manipulation, the soil soon reverts hack to a stable range of
values under field conditions.
