Surface soils and aerial parts of Korean lawn(Zoysia koreana) at normal fair way of 4 golf courses and yellow discolored fairway of one golf course in Kyonggi province were taken at and analyzed for mineral contents in soil Mg and Ca were most deficient while EC was too high and phosphorus was exess. There were significant positive correlation between pH and Ca and between EC and total N. There was no consistent simple correlation between single component in soil and plant, indicating the involvement of multi-minerals in one mineral absorption. m mineral contents of aerial part Mg was severely low. potassium moderately but Ca was normal, Mg and Ca showed significant correlation in aerial part, yellow-discolored lawn showed the lowest content of Mg in aerial part and surface soil. Very high N and high phosphorus in aerial part inspite of low P in soil. The above facts indicates Mg deficiency in fair way soils in most golf courses resulting in yellow-discoloration in lawn.

Effect pf rape seed oil cake compast (OM) active carbon(C) compound fertilizer (NPK) and magnesium sulfate (Mg) application on Zoysia koreana growth by lysimeter of 50cm soil column filled with a low fertility loam. Effect on growth was in order of OM>OM . NPK interaction> NPK . active carbon and Mg were not effective OM . NPK interaction effect was negative on leaf width and root dry matter yield. OM and OM . NPK interaction were most effective on rhizome growth. Their effect did not change the ratio of growth rates between aerial part and rhizome but change that between aerial part and root. Leaf width was most sensitive to the treatments.

An attempt has been made to extend the Optimum Utilization Period (OUP) of grassland through the use of sequential utilization of grass cultivars during the primary growth of grass. This experiment was carried out on the experimental field of Giessen University in Germany during the years 1977 to 1979. The results obtained are summarized as follows: 1. A substantial improvement of forage quality could be achieved by the sequential utilization of available grass cultivars. 2. The termination and duration of OUP was more closely related to development of grass than to calendar dates and OUP was from the development of 2nd node to boots-stage. 3. The duration of OUP in the sequential utilization of grass cultivars was 48 days, while it was 18 days in mixture grassland. 4. Without regard to grass growth, the forage quality of 2nd and 3rd growth was comparatively stable within the optimum range from an animal nutrition point of view. 5. The intake and utilization rate of forage in the sequential utilization of grass cultivars were shown 7,295 DM kg per hectare and 74% respectively. The figures are larger than those of mixture grassland. 6. The intake and utilization rate of forage in mixture grassland were appropriately better in early utilization, although dry matter yield was poor. In contrast to this, the intake and utilization rate of forage in latter utilization were poor, although dry matter yield was high. There were, therefore, a lot of forage rest on the field.
