“…29개 지점 중 8개 지점의 pH가 적정범위보 다 아래인 5.6~6.2로 약산성을 띄는 것으로 조사되었다. 토양의 pH는 양분 흡수와 관련하여 강력한 영향력을 가지며 작물생육과도 관련이 있는 중요한 토양화학적특성 중 하나이다 (Tagliavini et al, 1995;Kang et al, 2010). 토양이 산 성화되면 농작물의 생산성이 급격히 감소되며 중금속을 포함한 대부분의 금속의 용해도가 증가하여 식물의 생육에 해를 입히기 쉬운 상태가 되기 때문에 토양개량을 위한 시비방법이 절실히 필요하다 (Park et al, 2001).…”

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.

The aim of this study was to evaluate the effects of different propagation methods and cutting collection time on the seedling quality and post-transplanting growth characteristics of 'Sulhyang' strawberry. For propagation, runner cuttings were collected three times independently from mother plants. Runners of the mother plants from pinning propagation were used as control specimens. There were 2.0, 5.3, and 6.7 cuttings per mother plant on May 8, June 5, and July 3, respectively, which indicated that collection in early May was insufficient to acquire an appropriate number of cuttings. The relationship between the number of cuttings collected and cumulative solar radiation was set as a logarithmic equation of y = 4.4113 ln (x) -24.4090. The survival rate of cuttings was highest in the June collection and lowest in the July collection based on the time sequence. During the nursery period, root activity was better in the transplants obtained in May and June compared to those obtained in July. On the day of transplanting, the top/root (T/R) ratio was lowest in the June collection and highest in the July collection based on the time sequence. The mean fruit weight was highest in the June collection, followed by the pinning propagation group, and it was lowest in the July collection. The cuttings collected in early June produced the most uniform transplants and had the most stable fruit yield among the pinning and cutting collections. In conclusion, considering the supply of a sufficient number of cuttings, the production of high-quality transplants and a more stable fruit yield, cutting propagation in early June was found to be superior to pinning propagation for 'Sulhyang' strawberry.

This study was conducted for investigate the effect of Starfish and Lacquer Tree by-product Fertilizer on Growth of Tomato Plants. When starfish and lacquer fertilizers were applied to tomatoes, the results of the root survival rate after transplanting tomatoes showed 93% root survival rate both in the control group and 10% starfish treatment, whereas 100% survival rate from 10% lacquer treatment, and 5% starfish with 5% lacquer mix. After transplanting, plant height was 173.0cm in10% lacquer treatment, and 191.13cm in 5% starfish with 5% lacquer mix were significantly higher than those of 144.5cm in 10% starfish single treatment. Chlorophyll content was significantly higher at 1.90 mg/g in the 5% mixed treatment group of starfish and lacquer compared to those of 1.47 mg/g in control. Among dry matter, 10% of starfish and 10% of lacquer treatments showed 13.69 g, which was 1.73 times higher compared to 7.92 g in control. Calcium content was significantly higher at 14.68 mg/L in the 5% mixture of starfish and lacquer compared to 11.41 mg/L in control. The higher the calcium content and hardness during storage, the lower the blossom-end rot incidence. The hardness of the fruit was the best in the mixed treatment of 5% starfish and 5% lacquer, and the shelf life was maintained over 60% even on December 8th. The highest tomato weight and marketable yield showed in the mixed fertilizer of 5% starfish and 5% lacquer. Therefore, the mixed 5% starfish with 5% lacquer tree by-product fertilizer can be used to promote the production and to improve the quality of tomato fruits preferred in markets
