What Are Cations?

0

Cations are the positive charged nutrients in the soil. The most common cations are Calcium, Magnesium, Potash, Sodium and Hydrogen. Their balance to each other and to the other negative charged nutrients is very vital. Following are some basic truths to consider about Cations: 1. Calcium is the most important nutrient in your soil and the proper balance of it to all other nutrients is very important. Discussed in greater detail, later on in the book. 2. A soil test is incomplete when the Sodium (NA) level is not included, which is common if you have been using a traditional dry fertilizer program. Sodium is the salt index to your soil WATCH IT CLOSELY!!! 3. All Cation nutrients have a HOLDING or PULLING capacity that are in relationship to calcium (CA is the base nutrient and the comparison ratios will be 1 to 1 for CA. NA the highest 1.82 to 1). This means NA has 1.82 times more pulling capacity than CA. or it has a lot more holding power. 4. NOTICE: If other cation nutrients are not

Cations are positively charged ions that are formed when an atom loses one or more electrons during a chemical reaction. To understand what this means, it is helpful to review some basic information about chemistry. Understanding what an atom is, something about atomic structure and properties, and then what happens during a chemical reaction all provide an important backdrop for considering cations. Everything on earth is composed of matter, which is in turn made of atoms. Atoms are extremely tiny and can only be observed with specialized scientific equipment. All atoms are composed of three main particles — protons, neutrons, and electrons. The number of protons, neutrons, and electrons in each atom is what makes elements different from each other. It also determines their chemical properties, or how atoms act under different conditions. Protons carry a positive electrical charge, neutrons carry no charge, and electrons are negatively charged. Protons and neutrons join together to fo
