Highlights
Acids alter the pH, EC, and Redox of soil and water
Pond soil fertility need to be improved to stabilize the pH, content, potential redox, salinity, c-organic, and porosity, so that the production of fish/shrimp is increased. The dynamics of these characteristics will affect the quality of the pond.The quality and quantity of buffer determine the success of pond improvement, in addition to soil character and good management through soil reversal, drying, Addition of fertilization will ensure the growth of flora and fauna
Humic Acid (HA) generated from the biodegradation of dead organic matter, is a complex mixture of different acids containing carboxyl and phenolic groups so that it functionally behaves as a dibasic acid or sometimes as tribasic acid
Summary
Acids alter the pH, EC, and Redox of soil and water. Average of water pH value before and after experiment each are 7.51 and 7.16. A field experiment with the applications of humic acid with doses 0 and 6 kg/ha of shrimp pond soil are added 2 weeks before seed stocking. Pond soil fertility need to be improved to stabilize the pH, content, potential redox, salinity, c-organic, and porosity, so that the production of fish/shrimp is increased.
