Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle, or that the element is part of some essential plant constituent or metabolite .
Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...
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 ...

Plant nutrients consist of more than a dozen minerals absorbed through roots, plus carbon dioxide and oxygen absorbed or released through leaves. All organisms obtain all their nutrients from the surrounding environment. [48] [49] Plants absorb carbon, hydrogen, and oxygen from air and soil as carbon dioxide and water. [50]
They do not need soil to grow, absorbing moisture and nutrients through little scale-like structures, called trichomes, on their surfaces. They grow on branches, tree trunks, and rocks.
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 ...
Why Do Houseplants Need Fertilizer? Houseplant fertilizer contains essential nutrients, like phosphorous, nitrogen, and potassium, which plants need for healthy growth. Fertilizers are essential ...
