2. Plant nutrients in soil - Wikipedia

   en.wikipedia.org/wiki/Plant_nutrients_in_soil

   Magnesium is one of the dominant exchangeable cations in most soils (after calcium and potassium). Magnesium is an essential element for plants, microbes and animals, being involved in many catalytic reactions and in the synthesis of chlorophyll. Primary minerals that weather to release magnesium include hornblende, biotite and vermiculite ...

3. Plant nutrition - Wikipedia

   en.wikipedia.org/wiki/Plant_nutrition

   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. This is in accordance with Justus von ...

4. Base-cation saturation ratio - Wikipedia

   en.wikipedia.org/wiki/Base-cation_saturation_ratio

   In 1892 Oscar Loew observed that both calcium and magnesium can be toxic to plants when there is an excess of one and a deficiency of the other, thus suggesting there may be an optimal Ca:Mg ratio. [ 4 ] [ 5 ] In 1901 Oscar Loew and D.W. May did further testing and suggested an ideal Ca:Mg ratio of 5 to 4, though for several species maximum ...

5. Magnesium in biology - Wikipedia

   en.wikipedia.org/wiki/Magnesium_in_biology

   Magnesium is an essential element in biological systems. Magnesium occurs typically as the Mg 2+ ion. It is an essential mineral nutrient (i.e., element) for life [1][2][3][4] and is present in every cell type in every organism. For example, adenosine triphosphate (ATP), the main source of energy in cells, must bind to a magnesium ion in order ...

6. Grass tetany - Wikipedia

   en.wikipedia.org/wiki/Grass_tetany

   A K/(Ca+Mg) charge ratio exceeding 2.2 in forages has been commonly considered a risk factor for grass tetany. Potassium fertilizer application to increase forage production may contribute to an increased K/(Ca+Mg) ratio in forage plants, not only by adding potassium to soil, but also by displacing soil-adsorbed calcium and magnesium by ion ...

   en.wikipedia.org/wiki/Calcium_deficiency_(plant...

   Calcium roots loss (blossom end rot) on a tomato. Calcium (Ca) deficiency is a plant disorder that can be caused by insufficient level of biologically available calcium in the growing medium, but is more frequently a product of low transpiration of the whole plant or more commonly the affected tissue. Plants are susceptible to such localized ...
