The two important and essential production bases of agriculture namely, land and water are limited for any country and are also degradable. Major agricultural fields of some of the coastal districts namely Guntur, Prakasam, Krishna, East Godavari and West Godavari of Andhra Pradesh (A.P) suffer with water logging and salinity problems. Soil samples collected from 44 locations were analysed for soil chemical properties to characterize the salinity problem in Kapileswarapuram, East Godavari district. The results obtained based on analysis were pH, EC, organic carbon, HCO-3,Ca++, Mg++and exchangeable sodium (meq/100 g soil) are 8.21, 0.55 ds/m, 0.32 meq/l, 13.24 meq/l, 48.72 meq/l, 22.85 meq/l and 1.49 meq/100 g soil respectively. From this results soils in study area is not suffering with salinity problem. The water table depths, SEW30, soil textural classification and hydraulic conductivity were used to characterize the water logging problem in study area. The water table of study area was found with in 2m from GL. SEW30 index was worked out to be 2820 cm days for sugar cane crop entire year. As this value is higher than the optimal value of 1400 cm days for sugarcane crop. Soil textural classification was carried out in study area, it is be observed that the percentage of clay is increased with the depth. This is a negative sign for the crop establishment. As the canal releases takes place, the water deep percolation is impeded and these exists stagnation of water in vadoze zone. Auger-hole method was used to determine hydraulic conductivity this is ranged from 0.08 to 0.28 m/day with an average of 0.18 m/day dominant soil texture in the area was clay because of this hydraulic conductivity is very low in the study area. Taking these three parameters into consideration the study area is under the problem of chronic water logging condition, which needs reclamation measures.
