PEMANFAATAN LAHAN KRITIS BEKAS GALIAN TAMBANG SEMEN DENGAN MENGGUNAKAN AMELIORAN ORGANIK UNTUK PRODUKSI JAGUNG (Zea mays)

Abstract

This experiment was intended to study effects of using a phosphate dissolving bacterium and mycorrhiza on the growth of maize crop on a critically ex digging mine lands of Tonasa Cement. This experiment had been done between March and September 2004. Results of the experiment showed the applications of Rhizobium and mycorrhiza increased yields of maize and soil nitrogen as well as phosphate absorption by the plant. The application phosphate at 40 t/ha may increase the soil quality of critical lands
