PPT-SALINITY MANAGEMENT FOR SOIL AND WATER

Module 4 Analysis and Evaluation of Inventory Information Module 4 Objectives Use inventory data to diagnose saline or sodic problems Determine extent of saline problem Determine existing condition of plant resources. GROUNDWATER INFORMATION SHEET Salinity Salinity is a measure of the amount of dissolved particles and ions in water. There are several different ways to measure salinity; the two most frequently use Nuclear Institute for Agriculture and Biology (NIAB) played an effective role to learn. . to live with salinity and make profitable use of saline land and water resources. . . Initially screening for salt tolerance species were carried out and the scientists identified one salt tolerant variety of cotton (NIAB-999) and one salt tolerant variety of wheat (Sarsabz) for salt-affected areas. Two salt tolerant mutants, one each of mungbean & cowpea were developed and an early maturing cowpea mutant line was also identified that can tolerate salinity up to EC = 10 dS m. Animals: Crabs. (Pachygrapsus). Plants: Duckweed. (Lemna Minor). Data: # Crabs on the Brick. Data: # of Living Duckweed. Methods. . - three tanks, one freshwater, one 17.5% salinity, and one 35% salinity.

Generally, salinity is defined as the ‘the total amount of solid material in grains contained in one kilogram of sea water and is expressed as part per thousands (%o) . e.g. . 30%o (means 30 grams of salt in 1000 grams of sea water). .
