Sulfur Transformation in a Saline Sodic Soil of the Lajas Valley

Efficiency of sulfur application with different sizes and rates in reclamation of a saline-sodic soil in laboratory columns

Stability of a Calcareous Saline-Sodic Soil During Reclamation

General guidelines to reclaim saline or sodic soils do not adequately consider variables such as pH and the presence of organic matter that are known to affect soil stability. Poor structural stability of sodic, saline-sodic, and high-pH soils adversely influences crop yields; promotes piping, tunneling, and slope erosion; and can accelerate the failure of water conveyance systems. We evaluated...

Applying Biochar and Mineral Amendments to Remediate the Chemical Properties of a Saline-Sodic Soil

The present study was intended to improve the chemical properties of a saline-sodic soil using the individual application of alfalfa residue and two biochars produced from sugarcane bagasse and walnut shell, at the weighting ratio of 5%; their concomitant application with gypsum, aluminum sulfate and the mixture of these two chemical amendments was considered. The experiment was conducted in th...

Improving Soil Physical Indicators by Soil Amendment to a Saline-Sodic Soil

The application of organic amendments can be an appropriate solution to reclaim and improve physical propertiesof saline-sodic soils. In this research, an experiment was performed under greenhouse conditions to study the effect ofamendments to the physical properties of loamy saline-sodic soil. The five treatments were control (withoutamendment), municipal solid waste compost (MC), vermicompost...

Effects of nano iron oxide powder and urban solid waste compost coated sulfur on chemical properties of a saline-sodic soil

The main limiting factors in saline-sodic soils are high amounts of salts, low soil organic matter (SOM) and lowavailability of macro and micro-nutrients. The effect of different amounts of nano iron oxide powder and urban solidwaste compost coated sulfur (USWCS) on the chemical properties of a saline-sodic soil was investigated. The experimentwas conducted using a randomized complete block des...
