BACKGROUND: Recently, as the consumption of freshjujube is increased, fertilizer in jujube cultivation isexcessively used to supply nutrient for large fruit produce. This study was conducted to obtain the useful data related tooptimum nutrient management technique for fresh jujubecultivation. METHODS AND RESULTS: Nutrient contents of thejujube orchard soils were investigated at 30 different jujubeorchards in Boeun, Chungbuk. Soil samples were collectedfrom the different orchards in June, both 2012 and 2013. Soil chemical properties such as pH, organic matter,available phosphate, and exchangeable potassium, calcium,and magnesium were analyzed. Soil available phosphates inoptimum level for jujube cultivation were 7% and 13% oftotal samples in the 2011 and 2012 respectively, and 73%and 57% were higher than optimum level. In ExchangeableK, 37%, 30% were optimum level, 63%, 67% were higherin the year 2011 and 2012 respectively. CONCLUSION: These results showed that nutrientcontents of soils were accumulated in jujube orchard ofBoeun area. Especially, available phosphate and exchangeablepotassium were greatly higher than their optimum level forjujube cultivation respectively.
