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...

An area of saline sodic soil was intensively drained and treatments of gypsum (31 t/ha) or sulphur (6 t/ha) were applied, while control plots received no ameliorants. Physical and chemical soil analyses showed gypsum to have an ameliorative effect slightly superior to that of sulphur. Both treatments were more beneficial than the control but differences were not always as great as expected. For...

Abstract Soil salinity represents one of the major threats land degradation and desertification under arid semi-arid environments. It has an adverse influence on soil-water-plant relationships, posing serious challenges to agricultural productivity. The main objective this work was monitor effect farmyard manure (FYM) application irrigation with low-quality water dynamics dissolved salts yield ...

The effects of drip irrigation and different cultivation methods on seedgermination and growth of Puccinellia tenuiflora in saline-sodic soils wereinvestigated in field experiments during 2008-2010 in the Songnen Plain, China.Drip irrigation was applied to waste saline-sodic P. tenuiflora grasslands for bothflat and ridge cultivation methods. Drip irrigation affected the distributions ofelectri...

Sodic soils have low organic carbon content, microbial load and their activities which were the biological indicators of soil health. Soil organic carbon is the kay factor which derives the soil functions. A field experiment was conducted to study the effect of different amendments and micronutrient mixture on soil biological properties. Gypsum+GM, DSW (distillery spent wash) and GLM (Glyricidi...

In situ remediation technologies for contaminated soils are faced with significant technical challenges when the contaminated soil has low permeability. Popular traditional technologies are rendered ineffective due to the difficulty encountered in accessing the contaminants as well as when employed in settings where the soil contains mixed contaminants such as petroleum hydrocarbons, heavy meta...

Soil salinity is a key abiotic stressor that negatively impacts plant growth and restricts land use by causing degradation (Gamalero, et al. [1]). Saline sodic soils are characterized their high soluble salt content pH, respectively, which result in imbalances nutrient cycling reduced organic content, carbon stocks, microbial activity the soil [3].
