acidified soil

Acidified soils will have a broad spectrum of chemical and biological changes.

The two-year study concluded that the red spruce and the sugar maple have been hurt in different ways by acidified soils.

Acidified soils are less productive, contribute to ground water recharge causing salinity problems.

Poor reproduction in forest passerines from decline of snail abundance on acidified soils.

Outline methods for restoring acidified soils and waters, and evaluate their efficacy.

Recent studies support the relationship between loss of base cations from acidified soils and reduced growth rates and health of trees.

If critical loads are exceeded for long periods, nutrient imbalances will develop in acidified soils and forest productivity will decline.

In southern Sweden, reduced calcium in acidified soils is believed to have caused a decline in terrestrial mollusc numbers and species in the past few decades.

Such acidified soils can no longer protect downstream ecosystems from acid rain; waters that drain these forests carry both acids and toxic aluminum into streams, lakes, and rivers.

In forests growing on relatively acidified soils, concentrations of both chlorophyll a and b, and of carotenoids in chlorotic needles were related only to foliar magnesium concentration.

The nutrient-poor, often heavily acidified soil is poorly aerated and is not suited to arable use on account of the poor growth performance of cultivated crops.Fritz Scheffer, Paul Schachtschabel: Lehrbuch der Bodenkunde.

His research at the Dorset Research Centre, Ontario Ministry of the Environment, included the impact of "acid rain" on forested catchments and wetlands, aluminum and acidified soil geochemistry, aqueous toxicology and toxic trace metal geochemistry.

Progressive leaching of base cations (Ca2+, Mg2+, K+, Na+) from soils causes soil acidification (replacement of base cations on soil exchange sites with H+ and Al3+) which can eventually lead to the drainage of acidified soil solutions into surface waters.
