520 _aThis study was conducted to characterize 12 randomly selected rice growing areas in three municipalities of Aurora (Casiguran, Dipaculao and Maria Aurora). Specifically it aimed to analyze the soil pH, organic matter content, total nitrogen available phosphorus and exchangeable bases such as potassium of the selected area and to evaluate the micro-nutrient status of the soils in terms of zinc, manganese, copper and iron of the selected area. A total of 12 sample sites were selected from the top three producing municipalities of rice. The composite soil samples were brought to Regional Soils Laboratory in San Fernando, Pampanga for ananlysis of pH, organic matter content, phosphorus, potassium and micro-nutrient contents. The pH of the soils ranged from 5.13 to 5.87 with a mean value of 5.39 to described as strongly acidic. The organic matter contents ranged from 1.65% to 7.74% with a mean value of 4.89 and described as high. The total nitrogen content of the selected rice growing farms in Aurora is ranged from 0.126 ppm to 0387 ppm with a mean value of 0.24 ppm described as medium. The available phosphorus content is ranging from <0.01 ppm to 15.59 ppm with a mean value of 1.98 ppm described as very low. The exchangeable potassium contents is ranging from 0,14cmol/kg to 0.61cmol/kg with a mean value of 0.31 cmol/kg described as low. The mean values of the micro nutrient content of the selected rice growing areas where as follows: Cu at 3.41 ppm, described as medium; Fe at 252.60 ppm described as high; Mn at 52. 35 ppm, described as high; and Zn at 0.69 ppm which is low.
