| This experiment was conducted to investigate the effect of the nitrogen fertilization levels on the content of $NH_4$ + -N in soil of 'Suffolk' Kentucky bluegrass and zoysiagrass. The results obtained are summarized as follows : 1.According to the nitrogen fertilization levels, the content of $NH_4$+-N in soil of Kentucky blue-grass and zoysiagrass was not significantly different. The content of $NH_4$+-N in soil of Kentucky bluegrass and zoysiagrass was highest in June and December and lowest in March and September. 2.The content of $NH_3$- -N in soil was increased by increasing the nitrogen fertilization levels in both Kentucky bluegrass and zoysiagrass. However, the deeper the depth of soil the less the content of $NO_3$- -N in soil. In 40~60cm soil depth, the content of $NO_3$- -N in soil was lower than l0ppm in average. Even in June, which was the highest month of the content of NOF-N in soil, the content of $NO-_4$~-N in soil was not overpassed the degree of 20ppm. Key words:Zoysiagrass(Zoysiojeponieo), Suffolk Kentucky bluegrass (Poa pratensis), $NH_4$+-N $NO-N_3$ |
