PENGGUNAAN KAPUR CaCO3 PADA TANAH DASAR KOLAM IKAN BERBEDA UMUR DI DESA KOTO MESJID KABUPATEN KAMPAR
Abstract: The research was
conducted from April until June 2012 at Soil and WaterQuality Management
Laboratory Fisheries and Marine Science Faculty of RiauUniversity. The aim of
the research is to know effect of CaCO3 lime to the pondbottom soil of chemical
fertility and the water quality. The method usedexperiment and randomized block
designs with 1 factor is CaCO3lime, with 5level of treatments doses of CaCO3
lime from 0 g/m2, 6.67 g/m2, 56.00 g/m2,112.00 g/m2, and 168.00 g/m2, and 2
groups is new pond age (0-4 years old) andold pond age (5-10 years old).The
result indicated that the some doses of CaCO3 lime to increase in pHsoil pond
age 0-4 years and 5-10 years is 168.00 g/m2 (P4). These conditionsresulted
increased of initial pH range from5.0-5.8to6.7-7.1, C-organic about0.75%,
N-total of approximately 0.07%, KPK approximately3.2 to 3.8me/100g,C/N
ratioaround10.0 to 11.1. Thewater quality improvementin bothagegroupsoccurred
frompH 5.7to 7.7, increased of turbidity, hardness, increased ofdissolved
oxygenat pond age5-10 years old and concentration ofnitrateinthepondage of 0-4
years old.
