In the present study micronutrients (Cu, Fe, Mn, Zn) were analyzed with some physico chemical properties of soils of Date Research Center at Turbat, Kech, Balochistan. The study was carried out during the year 1998-99, Eighty four composite soil samples from soil depths of 0-15 and 15-30 cm were collected from 42 spots. The soil samples were analyzed for texture, electrical conductivity, pH, Organic matter, Lime content and micronutrients (Cu, Fe, Mn, Zn). Soils of Date Research Centre at Turbat, Kech were sandy loam in texture at the depths of 0-15 and 15-30 cm. Those soils were alkaline in reaction, having pH 7.85 and 7.83 at soil depths of 0-15 and 15-30 cm. The electrical conductivity of soils were 10.61 and 13.25 dS/m at soil depth of 0-15 and 15-30 cm. Soils of Date Research Center at Turbat, Kech were generally moderately calcareous a both depths (0-15 and 15-30 cm) with averages of 10.53 and 10.34 respectively. At the depth of 0-15 and 15-30 cm soils were deficient in organic matter with means of 0.185 and 0.143 respectively. Micro-nutrients concentration at Date Research Centre at Turbat, Kech under study envisaged that, copper (0- 15) 9.56 were medium and 90.5% soil tested samples were high and (15-30) 2% medium and 98% soil tested samples were high. Fe (0-15) 100% were low, 2.4% medium 2.4% and 95.2 soil tested samples were high Mn (0-15) 100% were high and (15-30) 100 soil tested samples were high. Zn (0-15) 38% were low, 12% medium and 50% soil tested samples were high (15-30) 31% were low, 14% medium and 55% soil tested samples were high. The analysis revealed that the soil of Date Research Centre at Turbat were mostly sandy loam in texture. Soil were mostly alkaline in reaction and moderately to strongly saline soils were mostly calcareous in nature, low in organic matter and micronutrient Cu and Zn were adequate while Mn and Fe were high. The findings of the present study show that at present as adequate amount of micronutrient in the surveyed soils.
