Impact of Continuous Application of Swine Slurry on Changes in Soil Properties and Yields of Tomatoes and Cucumbers in a Greenhouse

摘要: Five year term study from 2002 to 2006 was carried out examine the effects of continuous long-term application swine liquid manure on soil chemical properties including heavy metal contents and yield tomato (Lycopersicon esculentum) cucumber (Cucumis sativus L.) in a greenhouse. Treatments were conventional fertilizers three types slurry; Slurry composting biofiltration (SCB), Thermophilic aerobic oxidation (TAO), Bio-mineral water (BMW). Total nitrogen level SCB, TAO, BMW 0.47%, 0.09%, less than 0.01%, respectively. The manures much lower Korean regulation level. phosphorus, potassium, after five slurry not significantly higher those fertilizer use. Contents metals leaves crops did show significant difference among treatments. levels copper zinc, plant essential elements, range optimum growth. Yields for different that fertilizer. results implied may deteriorate phosphate trace elements greenhouse soils when they are applied as basal fertilization at recommended rate based testing.
