ABSTRACT:
Acid sulphate soils are identical to the presence of pyrite, low soil pH and nutrient eficiency. Sulfate Reducing Bacteria
application is hoped can reduce the use of lime in increasing acid sulfate soils fertility and increase the growth of corn plants.
This study aims to identify the effect of sulfate-reducing bacteria and ameliorants on pH, C-organic and corn plant height.The
research was conducted in the Greenhouse and Soil Laboratory of the Faculty of Agriculture, Universitas Sumatera Utara, using
a randomized block design with 2 factors. The first factor is sulfate reducing bacteria, namely B0 = without bacteria application
(Control), and B1 = sulfate reducing bacteria application. The second factor is soil ameliorant application, namely P0 = no
ameliorant (control); P1 = Oil Palm Empty Fruit Bunches (OPEFB) organic material; P2 = OPEFB organic matter + NPK
fertilizer; P3 = CaCO3 + NPK fertilizer with 4 replications. The analysis results showed that sulfate-reducing bacteria could
increase soil pH but did not increase soil C-Organic content. Meanwhile, soil ameliorants increase soil pH and plant height. The
interaction of sulfate-reducing bacteria and CaCO3 (ameliorant) + NPK fertilizer was able to increase soil pH by 7.07.
