T he correlation betw een soil pH, organic matter and available nutrients w ere analyzed. The results showed that the pH values of soils ranged from 7. 73 to . 39 belonging to mild alkaline and alkaline soils. There w ere low and low er contents of organic matter ranging from 9. 29 to 1 . 75 g/ kg. The content of avail able N ranged from 34. 34 to 46. 10 mg/ kg, available P ranged from 96. 6 to 146. 13 mg/ kg, available K ranged
