Positively charged ions

A cation is defined as a positively charged ion. This occurs when an atom or molecule loses one or more electrons, resulting in a net positive charge. Cations are essential in various chemical processes, particularly in soil chemistry, where they play a crucial role in nutrient availability and plant growth. They interact with negatively charged soil particles and organic matter, facilitating the retention and exchange of important nutrients such as potassium, calcium, and magnesium. Understanding cations and their behavior in soil helps in managing fertilization practices effectively, ensuring that crops receive the necessary nutrients for optimal growth.
