SALIENT SOIL CHARACTERISTICS AND POTASSIUM FIXATION IN VEGETABLE GROWING SOILS OF RANGA REDDY AND MAHABOOBNAGAR DISTRICTS OF TELANGANA
Journal Title: International Journal of Agriculture Sciences - Year 2017, Vol 9, Issue 16
Abstract
In the present investigation salient soil characteristics and potassium fixing capacities of vegetable growing soils of Rangareddy and Mahaboobnagar districts were studied during the year 2013-14. Rangareddy and Mahaboobnagar soils were slightly acidic to moderately alkaline in reaction, non saline in nature, organic carbon was low to high, low CEC. The texture of the soils of Ranga Reddy were loamy sand, loam and sandy loam and Mahaboobnagar were sandy loam, loam, loamy sand and sandy clay loam. The data revealed that the soils of Ranga Reddy and Mahaboobnagar districts were light textured with sand as dominant fraction. The potassium fixing capacity of soils of Ranga Reddy district varied from 11.2 to 44.8 kg ha-1 with a mean value of 20.3 kg ha-1. The K fixing capacity of soils of Mahaboobnagar district found to be in the range of 11.2 to 67.2 kg ha-1 with a mean of 23.8 kg ha-1 Potassium fixation capacity was low. Potassium fixation capacity of soil showed positive correlation with all soil characteristics except sand, which was significantly and negatively correlated (r = -0.647**). Presently the study indicated that soil properties have profound influence on potassium fixation capacity of soils.
