Top processes

Pedogenic carbonate accumulation and calcrete formation

7 steps

Soil inorganic carbon: pedogenic carbonate formation and dissolution

4 steps

Start: Soil inorganic carbon: pedogenic carbonate formation and dissolution
End: Soil inorganic carbon: pedogenic carbonate formation and dissolution
Evaporation and root water uptake concentrate the solution, and calcite precipitates (Ca2+ + 2HCO3- gives CaCO3 + CO2 + H2O) at the depth of wetting

Pedogenesis and soil horizon development

1 step

Calcification: carbonates and salts accumulate at the depth of wetting

Phosphate sorption on Fe and Al oxides and phosphorus availability

1 step

Liming to pH 6 to 7 reduces positive surface charge on oxides and modestly raises phosphate availability

Living soil system

1 step

Soil inorganic carbon: pedogenic carbonate formation and dissolution

Micronutrient availability: pH, redox and plant mobilisation of Fe and Zn

1 step

In calcareous soil at pH 7.5 to 8.5 inorganic Fe3+ falls far below the roughly 10^-8 M plants need, so Fe chlorosis appears
