Plant stoichiometry at different scales: element concentration patterns
Introduction. All plant species require at least 16 elements for their growth and survival, and some species may need an additional four (Mengel & Kirkby, 2001).Because N and P generally are the elements limiting plant growth rates, most studies of plant stoichiometry have focused on these elements, and it is clearly established how the requirements of these two …

Uptake And Transport Of Mineral Nutrients
Plants obtain carbon and oxygen from the atmosphere. The remaining mineral nutrients are absorbed from the soil through the plant roots. Mineral nutrients are the chemical elements required as essential nutrients by all plant species to perform all the necessary functions. Altogether, plants require thirteen different types of minerals.

The role of gravity concentration in modern processing plants
That such an ancient and inherently simple process has not only survived, but thrived, is in part due to its very simplicity. Not only is gravity concentration the process of choice in small, remote, artisanal plants, it also continues to play a major role in larger, "modern" plants for the concentration of many minerals, literally from A (andelusite) to Z (zircon).

Relationship between mineral nutrition, plant diseases, and pests
Mineral nutrient supply or tissue concentrations affect plant diseases and pests in various ways. The supply of nutrients changes the resistance of plants to pathogens and pests by altering growth and tissue composition (e.g., concentration of soluble compounds or defense compounds), the expression of plant defense and pathogen/pest virulence genes, and the …

Nature of Mineral Nutrient Uptake by Plants
The resulting concentration gradient that forms from the bulk soil to the root surface causes nutrients to diffuse along that gradient towards the root surface. Conversely, elements delivered to the root surface in excess of plant demand establish a concentration gradient away from the root surface and diffusion is then away from the plant root.
