Soil Change Varabilties of Shrimp Cultivation
Abstract
Variability of pond soil variables has an important role in many bio-environmental systems including
the pond environment. This study aims to determine the variables of pond land. Determination of
measurement points and soil sampling is done randomly at 67 sample points. A total of 11 soil
chemical characteristics were measured in the field and analyzed in the laboratory. The results
showed that in general, the type of soil in the pond area was alluvial soil with non-sulfuric acid. The
average negative potential for pond soil redox is -102 mV. The C-organic content of pond soil varies
from 0,51 to 2,72% with an average of 1.60%, the PO4 content in pond soil is classified as low,
between 3,27 and 53,01 ppm with an average of 20,75 ppm, meanwhile, the content of toxic elements
such as Fe and Al in the ponds is classified as low, with an average of 529,6 and 205,0 ppm
