As a result of the differing adsorption behavior of arsenite and arsenate on soils, the solubility of arsenic in soil pore water is dependent on its oxidation state.
However, our understanding about drivers of soil P solubility is still incomplete.
The high levels of alkaline can influence soil nutrient solubility (Messenger [1986]) and lead to soil fertility imbalance, deficiency, and chlorosis symptoms (Harrell et al. [1988]).
Possible mechanisms underlying biochar mediated increases in soil Mn solubility and decreases in corn Mn uptake were discussed.
Although Si is found plentifully in both silicate and oxidase forms in the soil, Si solubility in the soil solution is an obstacle for plant absorption because monosilicic acid is the only form of Si that plants can absorb.
In support of this, Oliveira et al. (2007) found that an increase in rhizosphere pH through fertilization with nitrogen (N) in the nitrate (N O 3 − ) rather than ammonium (N H 4 + ) form increased soil Si solubility and uptake in rice.
In C and the S-treated bulk soils, Mn solubility returned to values slightly above the Manganite line (Supporting Information Figure SI-7) within 2 to 6 weeks.
The physical chemical properties of the substance (water solubility, soil organic carbon water partition coefficient) cause high mobility and high concentrations in groundwater.
The variables which control the reaction of phosphate in soil are the solubility of fertilizers, the inorganic or organic form, soil pH, presence of calcareous materials and water management practices (Ranjan et al. 2013).
The major factor governing metal availability to plants in soils is the solubility of the metal associated with the solid phase, since in order for root uptake to occur, a soluble species must exist adjacent to the root membrane for some finite period.
Furthermore, Garcia-Mina et al. [21] observed that the ability of Fe humic complexes to increase Fe root uptake and Fe concentration in leaves in several plant species grown in soils prone to Fe deficiency was more likely linked to Fe HS complex solubility in soil solution than to their stability.
