Abstract
The 420 paddy soils samples of cultivated horizon from Long Yan city were analysed. The results were as follows:The mean contents of exchangeable Mg were 0.37cmol/kg. The exchangeable Mg in paddy soils were rather scarce and that in tide sand paddy soils were more scarce than that in other paddy soils. The contents of exchangeable Mg were increased gradually from west to east and north to south in Long Yan city and that were accumulated in low horizon of paddy soils. The regression analysis revealcd that positive correlation between the contents of exchangeable Mg and pH were of great signiticance. The yickl of rice was increased evidently and the yellow disease of rice lacking Mg were corrccted through application Mg fertilizer in paddy soils.
