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.

The minerals in the soil are classified into two categories, namely. Primary Minerals in soil: These are minerals which have not been chemically altered since deposition. They are same or similar to their parent materials. Often these materials are bigger in size and irregular in shape. These primary minerals are usually found in sand and silt.
Examination of mineral surfaces with a microscope may reveal some changes due to biogeochemical weathering (Spiers, et al., 1989), but most primary minerals in Canadian soils have been only minimally altered by chemical actions in the last 5,000–18,000 years. Once brought to the Earth's surface most primary minerals are not chemically stable.

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. What are three important minerals found in soil? THE PRIMARY MINERALS. Nitrogen (N) Key functions: When plants absorb nitrogen, it's transformed into amino ...
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 …
Examples of the primary minerals in soil include silica minerals and silicate, titanomagnetite, apatite, iron minerals, volcanic gases and non-crystalline inorganic constituents.
