Nitrogen ions have been generated in the air by corona glow discharge plasma. The unipolar current sturation of Sigmond has been observed and nitrogen ions were used for enrichment of nitrogen in compost of palm oil empty fruit bunches. Generator of ions was a positive corona discharge plasma with multi point to plane electrodes configurations and by using a DC voltage source of 6.8 kV and 8 mA. In the glow discharge plasma condition, the nitrogen ions were produced in air. Implantation of nitrogen ions can increase the levels of nitrogen in the compost. The highest percentage of nitrogen in the enrichment compost was (3,4 ± 0.3) % and we compare with compare with compost control without ions radiation was 1.1% (mass percentage). It can be concluded that the increasing of nitrogen content in the compost can be done by almost 300%.
Key words : corona glow discharge plasma, compost, nitrogen ionic
