Abstract:

Application of manure has been used to increase the nitrogen status of many arid and semi-arid agricultural soils, however, organic nitrogen contained in animal manures must be mineralized prior to utilization by crops. Nitrogen mineralization is, like other biological processes, affected by soil water status. This can be due to the direct influence of soil moisture and/or salt interactions on the nitrogen dynamics. It is critical to understand the interactive effects of salt and water on nitrogen in soils amended with organic fertilizer. Such knowledge may be used for improving and quantifyin

Parmi les contraintes abiotiques la salinité est considérée comme un problème majeur, qui affecte le fonctionnement des plantes, en particulier leur croissance et leur rendement. Afin d’étudier le contrôle génétique de la tolérance à la salinité chez Medicago truncatula, plante modèle de la famille des légumineuses, deux expérimentations ont été réalisées. La première expérimentation visait à étudier l’effet de la contrainte saline sur différents paramètres morpho-physiologiques pour un panel de génotypes de M. truncatula afin de déterminer les traits de phénotypage pour la tolérance à la sali

Abstract:

Nitrogen (N) loss in the form of volatilized ammonia (NH₃) is a considerable problem when ammonium (NH₄⁺) forming fertilizers are applied to calcareous or alkaline soils. Large areas of agricultural land, contain alkalinity and salinity problems, are potentially suitable for crop production with little alteration. This study was conducted to determine and compare the effectiveness of urea phosphate (UP) in reducing soil alkalinity and NH₃ loss. The volatilization of NH₃ from UP and urea (U) was studied on 3 selected soils (Hayhook SL, Laveen L and Latene L) using an aeration system. Urea phosp

It could arise from industrial activities, as well as pesticide use in agriculture, among other sources. For adequate protection of the soil ecosystem from metal toxicity, the bioavailability of metals must be properly evaluated. A plethora of soil factors affect the bioavailability of metals to soil organisms. These include pH, clay and organic matter contents, salinity among others. While much is known about the influence of some of these p

Abstract:

This study investigates the relationships between vegetation and salinity and sodicity in wetland meadows in the Chilcotin region of British Columbia. Eleven vegetation communities and one group of releves with no vegetation were identified using cluster analysis. An exchangeable sodium per cent of 15 and an electrical conductivity of 4 mmhos/cm were found to be appropriate boundaries for distinguishing between saline and sodic tolerant and intolerant vegetation communities. Some salt tolerant species and communities occurred in fresh conditions; however, intolerant species and communities w

An important adaptation in organisms to withstand osmotic variations in their external medium, is their efficiency of regulating intracellular concentration. In this context, cell volume regulation appears as a fundamental mechanism. The problem of cell volume regulation becomes crucial in the establishment of organisms in aquatic environment with fluctuating osmolarities.

Abstract:

In a context of international reduction of greenhouse gases emissions, CCS (ce{CO2} Capture and Storage) appears as a particularly interesting midterm solution. Indeed, geological storage capacities may raise to several millions of tons of ce{CO2} injected per year, allowing to reduce substantially the atmospheric emissions of this gas. One of the most interesting targets for the development of this solution are the deep saline aquifers. These aquifers are geological formations containing brine whose salinity is often higher than sea water's, making it unsuitable for human consumption. However

Soil salinity is predicted to become more severe and widespread adding more challenges for sustainable crops production worldwide.

Abstract:

Soil salinization is the accumulation of water-soluble salts in the soil to a level that impacts on agricultural production. Approximately 20% of the world’s cultivated land, or 6% of the world total area, is threatened by salinity. Hence, soil salinization is becoming the main challenge of the modern agriculture. Of all the cereals, wheat (Triticum aestivum) is a moderately salt-tolerant crop while barley (Hordeum vulgare) is classified as relatively salt tolerant. Within Triticum genera, durum wheat (Triticum turgidum ssp. durum) is less salt-tolerant than bread wheat (Triticum aestivum). Sa

Improving salinity tolerance is a challenging task that requires understanding key physiological traits in naturally salt tolerant plant species.

Crude oil recovery is related to surface wettability, which is controlled by crude interactions with rock surfaces.

This is a difficult task because of varying crude oil composition, asphaltene interfacial and chemical activity, and the potential of irreversibly contaminating analytical equipment by such s

Soil salinity seriously limits global agricultural production resulting in over US$27 billion per year economic losses. Rice (Oryza sativa) is a basic staple food that feeds about 50 % of the global population but is considered to be highly salinity sensitive among all cereal crops. While wild relative of rice possesses salinity tolerance, this trait was lost during domestication of Oryza sativa species.

Wheat and barley are ranked the second and fifth most important crops in terms of dry matter production. Both of them are classified as glycophytes, and their production is strongly affected by soil salinity. Thus, given the extent of land salinization in the world and predicted population growth to 9.3 billion by 2050, creating salt tolerant wheat and barley germplasm remains one of highest priorities for breeders.
