Soil fertility status of Taluka Hala, district Hyderabad

To determine the fertility status of soil of taluka Hala, district Hyderabad, twenty profiles were selected and sixty soil samples in the successive layer of 0-15 and 15-30 and 30-45 cm were collected at random. Soil samples were analyzed for some of the physicochemical properties. In general 70% for the soil samples were heavy and 30% were medium in texture. EC value of soils of taluka Hala, district Hyderabad were non- saline at 0-15, 15-30 and 100% soils were non-saline, at the depth of 30-45 cm respectively. The analytical results for soil pH indicated that 100% soils were moderately alkaline at all the depths where pH ranges from 7.6 to 8.2. Organic matter content of the surveyed area showed that 35% soils were poor, 45% were medium and 20% soils were adequate at surface (0-15 cm). At the sub-surface (15-30 cm), 85% were poor and 15% soils were medium and at the depth of 30-45 cm, 100% soils were adequate in organic matter content. Lime content of soils of surveyed area showed that 100% the soil samples at 0-15, 15-30 and 30-45 cm depths were moderately calcareous in nature. Total nitrogen content of soil at 0-15 cm depth showed that 70% soil samples were poor, 30% medium. At the sub-surface (15-30 cm), 100% were poor and at the depth of 30-45 cm, 100% soils were poor in total nitrogen content. Available phosphorus of soil profiles at 0-15 cm depth showed that 20% soil samples were low, 75% medium and 5% soils were adequate. However, at the depth of 15-30 cm, 65% of the soil samples were low, 35% were medium and at the depth of 30-45 cm, 80% of the soil samples were low and 20% soils were medium in available phosphorus. The analytical results further demonstrated that at 0-15 cm depth, 100% soils sample were adequate in available K content. While at the depths of 15-30 and 30-45 cm, 100% soil sample were adequate in available K. It was the concluded that the soils of taluka Hala, district Hyderabad were mostly heavy and medium in texture, non-saline, moderately alkaline in reaction, moderately calcareous in nature. Organic matter, total nitrogen and available phosphorus were low in medium in soil, while available potassium was quit adequate. Therefore, the application of organic matter, nitrogen and phosphatic fertilizer is suggested to maintain soil fertility as well as yield of the crops in this area.
