The soil mineral apatite is the most common mineral source of phosphorus, from which it can be extracted by microbial and root exudates, [79] [80] with an important contribution of arbuscular mycorrhizal fungi. [81] The most common form of organic phosphate is phytate, the principal storage form of phosphorus in many plant tissues.
The process of replenishing mineral levels in a soil is called soil remineralization. While studying alternative ways to replenish ground nutrients, it has been found that agrominerals can also help mitigate other issues such climate change , water preservation and soil management .
Topsoil is composed of mineral particles and organic matter and usually extends to a depth of 5-10 inches (13–25 cm). Together these make a substrate capable of holding water and air which encourages biological activity.
The main deposits include Barbara deposits of Kuch near Kalabagh in Mianwali District. The Dolomite deposits are also found near Datta Nala (about 11 km North East of Makerwal ). Doya-Lunda, Normia and Punnu (Near coal mines of Mulla Khel) and near Buri Khel in Mianwali.
Minerals in soils are found in two types; primary and secondary. [5] "A primary mineral has not been altered chemically since its crystallization from a cooling magma." [5] Additionally, a primary mineral is defined as a mineral that is found in soil but not formed in soil, whereas secondary minerals are formed during weathering of
Plants obtain minerals from soil. [8] Animals ingest plants, thus moving minerals up the food chain. Larger organisms may also consume soil (geophagia) or use mineral resources such as salt licks to obtain minerals. Finally, although mineral and elements are in many ways synonymous, minerals are only bioavailable to the extent that they can be ...

The precipitated minerals within the soil of these inland sabkhas depend significantly on the specific composition of the local groundwater. Thus, the geological and chemical composition of these environments may differ widely based on regional groundwater characteristics.
