Abstract

The use liquid organic fertilizer (LOF) has been found to be effective as complimentary nutrients for solid organic fertilizer in organic vegetable production. The amendment of zinc (Zn) increased the activities of decomposing microbes to decompose solid organic fertilizer which eventually increased nutrient contents. However, reports on the effects of Zn addition in the production process of LOF on its nutrient properties are very limited. This experiment was, therefore, established to determine the effect of the Zn amendment on LOF nutrient contents. An experiment was conducted using randomized complete design with three replications. Treatments consisted of 0, 25, 50, 75, and 100 ppm of Zn that amended during the production of LOF. Results indicated that the addition of Zn significantly decreased N and organic C of LOF. However, Zn amendment did not significantly decrease P and K contents. In addition, decreased N was significantly correlated with decreased organic C, but decreased P and K in LOF nutrients were not correlated with decreased organic C content. Future research should consider using lower Zn concentrations in the process of LOF production.
