        Abstract

        One role of humic acid is a buffer agent to control the stability of the soil reaction. 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. Seedsare stocked with a density of 1000 fries per hectare. The experimen tal results indicate that administration of humic 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. Soil pH, EC and redox values before and after the administration of humate each are 7.51 and 7.48, - 22.83 and - 5.00, and 129.67 and 63.33 ppm. Average shrimp weight of 2 months 10 days old is 16.46 with a range of 14.8 - 18.9 g or equivalent of size 50 - 60. These conditions are suitable for fish or shrimp.
