The term "mineral" is archaic, since the intent is to describe simply the less common elements in the diet. Many elements are essential in relative quantity; they are usually called "bulk minerals". Some are structural, but many play a role as electrolytes. [2] These include:
A mineral lick (also known as a salt lick) is a place where animals can go to lick essential mineral nutrients from a deposit of salts and other minerals. Mineral licks can be naturally occurring or artificial (such as blocks of salt that farmers place in pastures for livestock to lick).
Animals are thought to better absorb, digest, and use mineral chelates than inorganic minerals or simple salts. [19] In theory lower concentrations of these minerals can be used in animal feeds. In addition, animals fed chelated sources of essential trace minerals excrete lower amounts in their faeces, and so there is less environmental ...
In plants and animals, mineral absorption, also called mineral uptake is the way in which minerals enter the cellular material, typically following the same pathway as water. In plants, the entrance portal for mineral uptake is usually through the roots. Some mineral ions diffuse in-between the cells. In contrast to water, some minerals are ...
Xylem moves water and mineral ions in the plant and phloem accounts for organic molecule transportation. Water potential plays a key role in a plant's nutrient uptake. If the water potential is more negative in the plant than the surrounding soils, the nutrients will move from the region of higher solute concentration—in the soil—to the ...
Energy flow is a unidirectional and noncyclic pathway, whereas the movement of mineral nutrients is cyclic. Mineral cycles include the carbon cycle, sulfur cycle, nitrogen cycle, water cycle, phosphorus cycle, and oxygen cycle, among others that continually recycle along with other mineral nutrients into productive ecological nutrition.

Grinding a mineral, like olivine, to a particle size that would be effective in the ground (1μm), takes about 1.5 gigajoules per ton of rock. [3] Research will be needed to find more efficient ways to crush rock for rock-powders to be a sustainable solution for replenishing plant nutrients.
Bone meal provides phosphorus and calcium to plants, along with a largely inconsequential amount of nitrogen. [4] The N-P-K rating of bone meal is typically 3–15–0 [5] along with a calcium content of around 12% (18% CaO equiv.), [6] although it can vary quite a bit depending on the source from 1–13–0 to 3–22–0.
