Abstract

Chemical properties of soils and mineral contents in plants grown at seventy one regions located in southern part of Korea were surveyed to obtain the basic information for sustainable management of plastic film house soils. The averaged soil chemical properties showed optimum levels in pH, organic matter, available boron, manganese, zinc contents, whereas available phosphate and exchangeable rations were highly accumulated. Available phosphate showed highly positive correlation with continuous cropping period. The contents of phosphate, potassium, calcium, and magnesium in the top soils were ranged from 912(Pusan)~1.796mg (Masan) ; $1.52(Pusan){\sim}2.93cmol^+$(Sunchon) ; $7.44(Masan){\sim}18.58cmol^+$(Changweon) ; $2.82(Changnyong){\sim}6.24cmol^+/kg$(Changweon), respectively. There were high levels of phosphorus and potassium in the leaves of plastic film house plants of pepper, cucumber, pimento, chrysanthemum, and carnation. And calcium and magnesium were more than two fold high in fruiting vegetables than flowering plants showing antagonistic utilization against potassium.
