Abstract/Contents:"Soil chemical properties were investigated to elucidate vertical movement of mineral nutrients in a fairway slope of a 27 year old golf course. Soil samples were taken at 10cm depths to 40cm on four sites 20 m apart, each along two parallel lines 100m apart on the slope (15°), in August. According to the similarity in the pattern of vertical distribution they could be classified into 6 distinctive groups and the slope tended to affect the vertical movement of minerals. The contents of calcium and magnesium increased with depth while NO3-N and zinc decreased and correlated positively. Soil pH showed significant positive correlation with depth, calcium and magnesium. Phosphorus content was highest in 10-20 cm depth although relatively high contents were found at the 30-40 cm depth in bottom of the slope situations. The iron (Fe) distribution pattern was similar to phosphorus. Potassium and ammonia (NH4) showed irregular patterns. Manganese was highest in the deepest layer at the lower sites of the slope but it was the reverse at the upper sites and negatively correlated with Fe. Copper content increased to about 25cm depth and then decreased. Electro-conductivity showed significant positive correlation with NO3-N. In this study it was found that magnesium, calcium and copper seem to be prone to deficiency due to fast leaching, while nitrate and phosphorus tend to accumulate in excessive amounts. Preventive measures should be taken to overcome acidification of the surface soil."
