Saline-sodic soil is one of the major threats to crop growth, production, and quality. Biochar amendment could alleviate adverse impacts saline-sodic stress in crops. However, effect biochar on root morphological, physiological functions, rice yield paddy has not been studied. Here, underlying mechanisms positive effects morphological characteristics functions roots under heavily amended with w...

In this study, leaching experiments were carried out by both continuous and alternate ponding methodsin the south of Khouzestan province. In equal applied water leaching, alternate ponding leachingmodel had a better performance than continuous ponding method in desalinization and dealkalization.In term of alternate method,there was not ayn difference between 5 and 8 day periods in one-meterdept...

Traditional mapping of salt affected soils (SAS) is very costly and cannot precisely depict the space–time dynamics soil salts over landscapes. Therefore, we tested capacity Landsat 8 Operational Land Imager (OLI) data to retrieve salinity sodicity during wet dry seasons in an arid landscape. Seventy geo-referenced samples (0–30 cm) were collected March (wet period) September be analyzed for pH...
