Our Ag class did an experiment that involved the positive and negative charges of soil particles. We used a battery, two copper rods, two copper wires with alligator clamps on each end and a jar of washed down dirt or mud if you will. We clamped one end of the wire to the battery and one end on the copper rod for bothe the positive and negative charges. We stuck the rods in the dirt. Most of the dirt clinged to the positive rod therefore, soil has a negstive charge (for the most part.

What are clay micelles?
Clay micelles are a type of soil colloid that are very small conglomerations of clay particles that retain a negative charge.
What is a cation and how do you get them?
= cation =An ion or group of ions having a positive charge and characteristically moving toward the negative electrode in electrolysis.An atom, or group of atoms with a positive charge. Cation exchange is the process whereby a cation in solution is absorbed by a solid, replacing a different cation. Thus, in soil science, if a potassium salt is dissolved in water and applied to a soil, potassium cations are absorbed by soil particles, and sodium and calcium cations are released.
How do plants absorb cations from the soil?
The roots release hydrogen ions into the soil, leaving a negative charge in the roots. The cations, being positively charged, are attracted to the negative charge.
What are positive and negative effects of ash fall?
positive: gives nutrient soil and gives free heating. negative: kills people and ash is poisonous.
