ponding of unsaturated soils and the final resulted redox conditions, cause different chemical and electrochemical changes. redox potential is one of the most effective factors in determination of chemical properties of ponded soils; as by influencing dissolution and sedimentation of minerals and the activity and uptake of soil nutrients. the study site with an extension area of area about 10 h...

management of unconventional water management in agricultural lands reduces environmental risks and increases its productivity. the purpose of this study was evaluating and comparing the effect of wastewater, saltwater and brackish water on some soil physical and chemical properties. for this purpose, five study sites including control area, irrigation with saltwater, brackish water wastewater ...

Paddy-upland rotation is an unavoidable cropping system for Asia to meet the increasing demand for food. The reduction in grain yields has increased the research interest on the soil properties of rice-based cropping systems. Paddy-upland rotation fields are unique from other wetland or upland soils, because they are associated with frequent cycling between wetting and drying under anaerobic an...

Antibubbles are ephemeral objects. Their lifetime is driven by the slow drainage of the air shell from the bottom to the top of the antibubble under the action of hydrostatic pressure. We show in this paper that this argument is only valid if the water used to make the surfactant mixture is saturated in air. Otherwise, two paths are used by the air, which conduct to the thinning and the eventua...

Soil yeasts exhibit an array of beneficial effects to plants viz., plant growth promotion, phosphate solubilization, nitrogen and sulphur oxidation, etc. Yeasts remain as poorly investigated group microorganisms that represent abundant dependable source bioactive/chemically novel compounds potential bioinoculants. Hence this study holds the key concept assessing performance soil with promoting ...

soil degradation means lose of soil quality which usually is caused by improper use of land by human. decline of soil quality includes lose of physical, chemical and biological properties of soil. this study aimed to identify and assess the quality of soil and land, to determine the type of land degradation and estimates their severity based on completed forms gathered field data and mapping th...
