The effects of humic acid copolymers on chemical properties of the soil are studied.The experimental results showed that specific surface area
the charge amount and the cation exchange capacity of the soil increased with dose of the copolymers in the soil.The effect of acrylic acid amount of the copolymers on specific area was different from that on the charge amount and the cation exchange capacity of the soil.The pH of the soil amended was raised.
