A Study of the Urban Garden Soil Health in Busan Area

Abstract

The study of urban agriculture is focused on conceptual, active and policy establishment, and studies on the health of the vegetable gardens are minimal. This study analyzed the chemical properties of urban vegetable soils. The area of 29 urban vegetable gardens in the Busan area was divided into suburban area and urban areas. In the urban areas, the soil of the vegetable garden was high in content of organic matter and exchangeable cations and it is believed that there is more fertilizer in urban areas. The average value and range of soil fertility items were 6.87 (5.64~8.04) for pH, 43.4 g kg -1 (6.6~88.3) for organic matters, 845.3 mg kg -1 (115.9~2758.1) for available phosphate, 1.30 cmol kg -1 (0.23~3.66) for K + , 17.27 cmol kg -1 (6.05~46.50) for Ca 2+ , 2.88 cmol kg -1 (0.94~3.49) for Mg 2+ , and 2.66 dS m -1 (0.53~10.40) for electrical conductivity.
