Weathering of primary silicate minerals in the natural soil …
A theoretical model for the weathering rate of silicate minerals in the laboratory and the natural soil environment has been developed where the rate is assumed to be proportional to the exposed surface area of the mineral, the soil moisture saturation and the chemical driving force, given as a kinetic expression. The kinetic expression describes the dependency of the …

What are the importance of minerals in the soil?
As primary minerals that originally formed at high temperatures and pressures in igneous and metamorphic rocks are weathered in soils, they release plant nutrients into the soil solution.

Understanding Phosphorus Forms and Their Cycling in …
Soil contains minerals that are rich in phosphorus. These minerals are classified into primary and secondary minerals. Minerals break down over time (a process referred to as weathering) and release phosphorus in the soil solution for plant uptake. Primary minerals such as apatite are very stable and resistant Figure 1. Soil phosphorus cycle.

primary mineral – a mineral which forms under conditions different from those at the surface of the earth, often by solidification from magma. secondary mineral – a mineral which forms at or near the surface of the earth, often from weathering products of primary minerals. The table below provides brief descriptions of minerals found in soils.
Weathering of the primary rock-forming minerals: processes, products
The general nature of any particular weathering profile will reflect the interactions between climate, topography, parent material, soil biota and time and superimposed upon this complexity, when considering how individual primary minerals break down in detail, will be factors related to the nature of the mineral itself.
