Sorption of heavy metals in organic horizons of acid forest soils at low added concentrations
acidic soils adsorption desorption organic matter risk elements
2015/3/13
The individual adsorption/desorption of Cu, Pb, and Zn in six soil samples taken from organic horizons of acid forest soils is studied in batch experiments. These three metals were chosen because of t...
Modelling the impact of acid deposition on forest soils in North Bohemian Mountains with two dynamic models: the Very Simple Dynamic Model (VSD) and the Model of Acidification of Groundwater in Catchments (MAGIC)

2015/3/13
Enormous acid deposition that culminated in the 1970s contributed largely to accelerate the process of acidification of soils in northern Bohemia. As a consequence a wide forest decline occurred short...
Wheat genotyp es diff ering in alumin um tolerance differ in their growt h res ponse to CO2 enrichment in acid soils
Acid soils Aluminum tolerance elevated CO2 growth response malate efflux wheat ( Triticum aestivum L.)
2015/2/5
Aluminum (Al) toxicity is a major factor limiting plant growth in acid soils. Elevated atmospheric CO2 [CO2] enhances plant growth. However, there is no report on the effect of elevated [CO2] on growt...
The identification of aluminium-resistance genes provides opportunities for enhancing crop production on acid soils
Acid soils aluminium citrate malate resistance roots tolerance
2015/2/5
Acid soils restrict plant production around the world. One of the major limitations to plant growth on acid soils is the prevalence of soluble aluminium (Al3+) ions which can inhibit root growth at mi...
