Free aluminium extraction from various reference materials and acid soils with relation to plant availability

Influence of parent material on the aluminium fractions in acidic soils under Pinus pinaster in Galicia (NW Spain)

“…The chemistry of Al-humus complexes also plays a major role in soil pH buffering and in the regulation of Al activity in soil solution (Mulder and Stein, 1994;Takahashi et al, 1995). The Al bound to organic complexes is of low toxicity (Adams et al, 2000;Matús et al, 2006), and this may explain the lack of negative effects of Al on the growth of tree species on acid soils.…”

The impact of introduced and indigenous woody plants on change of selected soil chemical properties in the arboretum Mlyňany

“…Matúš et al (2006) stated that aluminum is present in different chemical forms, of which free Al 3+ , Al(OH) 2+ a Al(OH) 2 + are critical for the evaluation of its toxicity, and for determining the impact of protons entry into the soil and surface water. Just these are released into the soil solution due to dissolution of minerals, or ion-exchange reactions (Čurlík et al, 2003).…”

Efficient preconcentration and determination of traces of aluminum ion using silica-bonded glycerol sorbent

“…The chronical effect of Al compounds is often connected with mortality of some animals and Alzheimer's or some other human neurodegenerative diseases [2][3][4]. The separation of Al in soil solution is important because this factor controls the toxicity of Al to plants and living organism [5][6][7][8].…”
