Combined application of organic and inorganic amendments was known to play a significant role in improvement of soil properties. A field experiment was conducted to explore the effects of gypsum, farmyard manure and commercial humic acid application on the amelioration of salt affected (saline sodic) soil. During this study, soil pH, electrical conductivity, sodium adsorption ratio, responses o...

Natural and cultural heritage sites frequently have nonoverlapping or even conflicting conservation priorities, because human impacts have often resulted in local extirpations and reduced levels of native biodiversity. Over thousands of years, the predictable winter rains of northwestern Baja California have weathered calcium from the clam shells deposited by indigenous peoples in middens along...

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...

, Abstract Results of the laboratory reclamation of four sodic soils by the high salt water dilution method are reported. The exchangeable sodium percentage (ESP) of all soils was decreased by leaching with solutions of decreasing sodium but constant calcium concentration. Although a final leaching with water of low electrolyte concentration (EC,, < 100 micromhos/cm) did not produce a rapid dec...

Excessive soil salinity is a problem that makes unusable for agriculture, and most current research focuses on either chemical supplements or water conservation measures. Nevertheless, more information needed about how sand treatment affects quality. In this study, field experiment assessed the effect of application cropping year properties in an arid semi-arid saline-sodic agricultural ecosyst...

Soil physicochemical properties are the main driving factors affecting stability and diversity of soil microbial community. The impacts saline–alkali situation associated degradation need to be understood reversed as communities increasingly affected by saline–alkaline soil. However, differences between salinization alkalization their impact on microbiota have been overlooked. object this study...

Soil sodicity is a significant crop production constraint around the world. Inherited tolerance precursor to pre-breeding and breeding tolerant cultivars. However, high yield per se seasonal variability are potential limitations identify real rather than escape correctly. To minimise this risk, we generated yield, components supporting data at two times of sowing (TOS) 15 lines representing fou...

salinity of soil and water is the most important agricultural hazard in arid and semi-aridregions. in saline soils, yield production directly influences by soluble salts in the root zone aswell as by shallow water table depth. the first step for reclamation of such soils is reducingsalinity to optimum level by leaching. the objective of this study was to develop a practicalmodel to estimate wat...
