PENGARUH PEMBERIAN PUPUK BOKASHI DAN ZEOLIT SEBAGAI BAHAN PEMBENAH TANAH TERHADAP KETERSEDIAAN NITROGEN TANAH REGOSOL

Regosol has been widely used for agricultural production despite its low nutrient availability and adsorption. This research aimed to know the effects of bokashi zeolite on nitrogen (N) in Regosol. The experiment was carried out with a completely randomized 2-factors design. first factor bokashi, three levels: 0 t ha-1 (B0), 20 (B1), 30 (B2). second (Z0), 5 (Z1), 10 (Z2). Each treatment repeated times. incubated days. parameters before being treated were texture, bulk density, pH H2O, N-totals, C-organic, available N, CEC soil, C-organic also zeolite. after C/N, leached NH4+ NO3- water. data analyzed ANOVA followed by DMRT at 5% level. results showed that significantly affected N-total, NO3-, CEC, meanwhile did not affect N but C/N NO3-. combination soil. best dose increasing (B1).
