front via capillary action in certain soils. • The weight of overlying soil restrains vertical growth of the ice and can promote the formation of lens-shaped areas of ice within the soil. • Yet the force of one or more growing ice lenses is sufficient to lift a layer of soil, as much as 30 cm or more.

Penetrometer (shown at right) consists of two 16-mm (5/8-inch) diameter shafts coupled near midpoint. The lower shaft contains an anvil and a pointed tip which is driven into the soil by dropping a sliding hammer contained on the upper shaft onto the anvil. The underlying soil strength is determined by measuring the penetration of the lower

Soil and groundwater petroleum hydrocarbon contamination has long been of concern and has spurred various analytical and site remediation developments, e.g., risk-based corrective actions (ASTM’s Risk-Based Corrective Action [RBCA]), EPA and state government underground storage tank (UST)
dispersal, habitat preservation and soil fertility.17,18 While agroecological approaches strive to maximise synergies, trade-offs also occur in natural and human systems. For example, the allocation of resource use or access rights often involve trade-offs. To promote synergies within the wider food system, and best manage

Ecosystems support all forms of life, moderate climates, filter water and air, conserve soil and nutrients and control pests. Species (animal and plant) provide us with food, building materials, energy and medicines. They also provide vital services such as pollination, waste assimilation, water filtration and distribution of seeds and nutrients.
