Data regarding the effects of contaminated boatyard soils on organisms have only been found in one recent study by Eklund et al. (2014).
The stingy soils on the glacier-scoured rock here provide footholds for pitch pines.
As the trees and soils on which the islanders depended disappeared, the population crashed and the survivors turned to cannibalism.
Heavy downpours often wash away the soils on bare ground or deplete them of their nutrients.
The age of soils on volcanic substrates can deeply influence plant growth.
Soils on the low-lying atolls are very limited in depth and quality.
The early settlers found the alluvial soils to be the most productive, but red-brown soils on upland slopes and in the state's south-central Riverina region and black soils on the northern river plains also are exceptionally fertile.
The vines grow in complex volcanic soils on a series of hillsides, some so steep they require terraces.
Pockets of alluvial soils on the south coast are somewhat fertile, but all farmlands there are fertilized.
Alluvial soils on the coastal plains chiefly consist of deep loam and clay, and residual clays cover the valley floors.
The same forces at work in streambank erosion are seen in soils on hillslopes that become thoroughly saturated with water.
