A plant with magnesium deficiency. Magnesium deficiency is a detrimental plant disorder that usually occurs in strongly acidic, light, sandy soils, where magnesium can be easily leached away. Magnesium is an essential macronutrient constituting 0.2-0.4% of plants' dry matter and is necessary for normal plant growth. [54]
Alkaline precipitation occurs due to natural and anthropogenic causes. It happens when minerals, such as calcium, aluminum, or magnesium combine with other minerals to form alkaline residues that are emitted into the atmosphere, absorbed by water droplets in clouds, and eventually fall as rain.
As water from rain, flooding, or other sources seeps into the ground, it can dissolve chemicals and carry them into the underground water supply.

An unusually cold weather system from the Gulf of Alaska interrupted summer along the West Coast on Saturday, bringing snow to mountains in California and the Pacific Northwest and prompting the ...
Plants deficient in magnesium show stress responses. The first observable signs of both magnesium starvation and overexposure in plants is a decrease in the rate of photosynthesis . This is due to the central position of the Mg 2+ ion in the chlorophyll molecule.
