NANO TECHNOLOGY OF ZEOLITE MINERAL FOR SLOW RELEASE NITROGEN OF
UREA FERTILIZER ON VERTISOLS PADDY SOIL

M. Al-Jabri

A Series Of experiments aimed to study the effect of zeolite as soil conditioner to the nitrogen (N) uptake, and to the dry rice grain yield in the greenhouse and the field condition have been done. The zeolites in this research was zeolite with trade mark Zeolite Kap Kan (ZKK). The results show that the higher addition of ZKK zeolite, the higher N concentration  was observed. The highest N concentration (2.96%) was obtained at dosage of 1 ton ZKK ha-1.  The weight of dry rice grain yield in the greenhouse increased with the addition of zeolite.  Similar tendency was observed when zeolite was used as soil conditioner in field. 6.52 ton ha-1 of dry rice grain has been reached at the ziolite addition of 2 ton ZKK ha-1
