  • This study were carried out to evaluate effect of consequent application of pig manure compost (PMC) on soil chemical properties, dehydrogenase activity, and yield of potato in volcanic ash soil. The more application rate of PMC increased, the more increased soil pH, total-nitrogen, available phosphate, exchangeable cations (K, Ca, and Mg), heavymetal (Zn and Cu)contents. When application rate of PMC and crop cultivation times increased gradually, soil dehydrogenase activity was significantly increased. After third cultivation period, dehydrogenase activity showed PMC 2 ton (3.5), PMC 4 ton (6.3), PMC 6 ton (8.0 ug TPF $g^{-1}\;24h^{-1}$), respectively. The activity was twofold higher than first cultivation period. During the third cultivation period, dehydrogenase activity increased linearly comparison to Cu and Zn contents and that was correlated with Cu ($R^2$=0.907) and Zn ($R^2$=0.859) content, respectively. As the application rate of PMC increased, the yield of potato increased, but NPK+PMC 2 ton treatment was more higher than other treatments.

  • We have researched the changes of paddy soil properties and rice yield by several different methods to treated with liquid pig manure(LPM). In the execution of this experiment, rice was cultivated to full maturity at a paddy field in Jeollabuk-do in 2011. Field experiment was designed with surface application on dry field condition+jet hose spray(Tr. 1), surface application on dry field condition+incorporation with irrigation water(Tr. 2), surface application on dry field condition+application device of fertilizer through irrigation(Tr. 3), submerged application on irrigated field condition+jet hose spray(Tr. 4), submerged application on irrigated field condition+incorporation with irrigation water(Tr. 5) and submerged application on irrigated field condition+application device of fertilizer through irrigation(Tr. 6) plot. Total N, P, K contents in used LPM were 0.44%, 0.07% and 0.14%, respectively. After the experiment, soil properties were not significant difference both several treated plots. But $NO_3$ and $NH_4$ contents at incorporation with irrigation water plots in paddy soil were higher than other plots. The yield was 602 kg $10a^{-1}$ in Tr. 2 plot compared Tr. 6 plot, which showed a value of 9.6% higher.
