Silicon (Si), aluminum (Al), and iron (Fe) are the three most abundant minerals in soil;
however, their effects on plants differ because they are beneficial, toxic, and essential to …

Abstract Aluminium (Al) and silicon (Si) are abundant in soils, but their availability for plant
uptake is limited by low solubility. However, Al toxicity is a major problem in naturally …

Aluminium and silicon are usually abundant in soil mineral matter, but their availability for
plant uptake is limited by low solubility and, in the case of Al, high soil pH causes …

Silicon (Si), although not considered as an essential element for plants in general, can
ameliorate the phytotoxicity induced by excess metal (loid) s whether non-essential (eg Cd …

Aluminum (Al) is the major element in the soil and exists as a stable complex with oxygen
and silicate. When the soil pH is below 5, Al is solubilized in the soil water and absorbed by …

Aluminium (Al) is the third most abundant metallic element in soil but becomes available to
plants only when the soil pH drops below 5.5. At those conditions, plants present several …

Silicon (Si) is the second richest element in the soil and surface of earth crust with a variety
of positive roles in soils and plants. Different soil factors influence the Si bioavailability in soil …

Aluminum (Al) is the third most ubiquitous metal in the earth's crust. A decrease in soil pH
below 5 increases its solubility and availability. However, its impact on plants depends …

Iron and phosphorus availability is low in many soils; hence, microorganisms and plants
have evolved mechanisms to acquire these nutrients by altering the chemical conditions that …

Aluminium (Al) toxicity is a very important factor limiting the growth of plants on acidic soils.
Recently, a number of workers have shown that, under certain conditions, silicon (Si) can …
