Water and soil salinity were monitored in Barisal, Jhalokhati, Pirojpur, Patuakhali and Barguna districtrs from October 2009 to April 2010. To collect water and soil samples, five districts were divided into two routs—Bakerganj-Patuakhali-Amtoli-Kalapara-Kuakata rout (A) and Jhalakati-Mathbaria-Patharghata-Haringhata rout (B). In rout A, fourteen locations were selected at an average distance of 5 kilometers. The water sample collection was started from Bakarganj followed by Lebukhali (Pyara river), Khalishakhali (Laukathi River), Shakhariabazar, Amtoli, Sekanderkhali (Harpangasia River), Kolapara, Andharmanik river, Pakhimara, Sonatola river, Bipinpur, Mohipur (Fafru canal) and Kuakata sea beach. Distances of the locations were 76, 72, 60, 50, 34, 30, 25, 23, 21, 17, 11, 8, 6, and 0 kilometers respectively, from the sea. In rout B, soil samples were collected from Nalchiti, Dhanshiri, Razapur, Charkhali, Dhanisafa, Tushkhali, Mathbaria, Raihanpur, Kathaltoli, Charduani, Pathorghata, Badurtala and Horinghata. Distances of the locations were 88, 75, 70, 56, 44, 40, 34, 26, 18, 14, 8, 6 and 4 kilometer respectively from the sea. Soil samples were collected from the fallow land at each location. At each location soil samples were collected from 3 or 4 places were mixed together. Depth of soil sampling was 5 to 10 cm from ground surface. Water samples were collected in plastic bottles. Salinity of all the soil and water samples was evaluated by measuring the electrical conductivity (EC) in the laboratory. The magnitude of soil salinity was conventionally assessed in laboratory by determining the electrical conductivity of a 1:5 soil:water saturated soil paste extract (ECe).
