Which nutrient is denoted by Ca when discussing soil amendments?

Calcium, denoted by the symbol Ca on the periodic table, is an essential nutrient in soil discussions, particularly regarding soil health and plant growth. It plays several critical roles in plant physiology, including the formation of cell walls, enzyme activation, and cellular signaling. Additionally, calcium helps to maintain proper soil structure by promoting the aggregation of soil particles, which improves air and water infiltration.

In the context of soil amendments, calcium can be supplied through various sources, such as lime (calcium carbonate) or gypsum (calcium sulfate). These amendments are often used to correct soil acidity, improve soil structure, and provide the calcium necessary for optimal plant growth. Understanding the role of calcium as a nutrient helps in managing soil fertility effectively, ensuring that crops have the necessary nutrients for healthy development.
