Introduction These soils are both saline and alkali. There can be all stages in transition with varying degree of dominance of salt content and pH According to movement of soluble salts, formation of saline-alkali and non-saline alkali soils depends. Soil contains Na-clay as well as excess soluble salts. 15-05-2021 pcte group of institute 4
Area distribution of saline alkaline soil 6.75 MHA land comes under the saline alkaline soil in the India Uttar Pradesh is the leading state in India where the 72% land comes under the saline soil. 15-05-2021 pcte group of institute 5

Physical properties Color of soil is very according to theedom Soil Structure is flocculated soil temperature 18 ֯ C ,28 ֯ C and 36 ֯ C High concentration of natural salt in this soil 15-05-2021 pcte group of institute 7
Chemical Properties Ph is lees then 8.5 Electrical Conductivity is more then 4 ds / m SAR is more than 13 ESP is more than 15% Concentration Of Boron is less than 0.7 ppm Organic matter is very high in the saline- alkaline soil 15-05-2021 pcte group of institute 8
Factor formation of saline-alkaline soil parent material Like quartz and granite is responsible for the formation of saline –alkaline soil uses of fertilizer ammonium sulfate and nitrate is also responsible for formation of saline-alkaline soil decomposition of organic matter carboxylic ad phenolic group 15-05-2021 pcte group of institute 9
Continue Topography With the help of runoff vegetation cover conifers and lack of alkali matter 15-05-2021 pcte group of institute 10
management of saline –alkaline soil Use Of Gypsum Leaching Of Salts Scraping Use Of Sulphur Use Of Acidifying Fertilizers Green Manuring Use Of Salt Tolerance Crops 15-05-2021 pcte group of institute 11
