Saline, sodic, and saline-sodic ground waters are problematic throughout the Northern Great Plains and Red River Valley. High sodium adsorption ratio (SAR) and low electrical conductivity (EC) of soil solution and irrigation waters are known to create issues with saturated soil hydrologic conductivity. Our objective was determine the impact of saline, sodic and saline-sodic solutions on soil shrinkage and soil hydrologic properties. Soil shrinkage, water retention, and hydraulic conductivity were determined on a variety of soil textures following saturation with salt solutions of variable EC a

Soil salinity is a widespread problem that affects crop productivity. We expect that saline soils also have altered microbial community structure, soil food webs and related soil properties. To test this, we sampled field soils across four farms in eastern North Dakota that host salinity gradients. We evaluated microbial biomass carbon, phospholipid fatty acid analysis and nematode counts in moderately saline and low saline soils. Additionally, we measured soil properties that represent potential food sources and habitat characteristics that influence microbial communities. We found higher mic

Salinity has been shown to reduce vegetative growth, crop quality, and yield in agricultural crops. Remote sensing is capable of providing data about large areas. This project was designed to induce salinity stress in a crop, pak choi, and thereafter monitor the response of the crop as expressed by its spectral reflectances. The project was conducted in the National Taiwan University Phytotron, and spectral data was collected using a GER 2600. Yield and soil salinity (ECe) were also measured. After three seasons of data were collected, wavelengths sensitive to salinity were selected. The

Annotation:

Soil is the worlds largest terrestrial carbon (C) sink, and is estimated to contain approximately 1600 Pg of carbon to a depth of one metre. The distribution of soil organic C (SOC) largely follows gradients similar to biomass accumulation, increasing with increasing precipitation and decreasing temperature. As a result, SOC levels are a function of inputs, dominated by plant litter contributions and rhizodeposition, and losses such as leaching, erosion and heterotrophic respiration. Therefore, changes in biomass inputs, or organic matter accumulation, will most likely also alter these levels

Soil salinity is one of the major problems in and and semi-arid zones, affecting up to 50% of arable land in Syria.

The long-term use of reclaimed water for landscape maintenance and the effects on soil chemistry and soil structure were investigated. Irrigation with reclaimed versus potable water for five years or more affects chemical properties of soil. Soils irrigated with reclaimed versus potable water had higher EC. Monsoon precipitation had less of a leaching effect than anticipated and significantly reduced EC only on two out of 13 sites. Soils irrigated with reclaimed water had higher SAR values than those irrigated with potable water and can potentially develop infiltration problems in the future.

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.

CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior<br>The coconut crop in Brazil stands out for its economic and social importance. The coconut cultivation has been in troduced in several regions of the country, however, the Northeast stands out with the largest plantations and production. Currently, a major problem in the agricultural sector, especially in semi-arid regions, has been the process of soil salinization. This problem is accentuated by the use of water with high salt concentration. Another factor existing in saline environments

Riparian buffers have been created as a sustainable and effective way to combat the harmful effects of excess nitrogen and soil salinity in riparian settings. The goal of this research was to determine what species will I) germinate in saline environments and II) establish and produce sufficient biomass while being exposed to increased nitrogen. Incubation of eight native riparian graminoid species were evaluated for their ability to germinate in MgSO4-induced salinity. In a greenhouse study, seven riparian graminoid species were evaluated to quantify their ability to survive and take up nitro

L’objectif général de ce travail est de comprendre et d’évaluer le rôle des cultures, à fort développement racinaire et susceptibles de se développer en milieu salin et saturé, sur le processus de phytodésalinisation des Vertisols. L’étude est réalisée sur le périmètre irrigué de Kollo (Niger) dans la vallée du fleuve Niger et couple deux expérimentations : i) la première in situ teste la capacité de Echinochloa stagnina à dessaler les Vertisols durant 15 mois en comparaison avec le riz (Oriza sativa) et le sol nu submergé et ii) la deuxième, au laboratoire sur des colonnes du sol, étudie l’ef

The first study was conducted during 2014 growing season at Glyndon, MN to evaluate the effectiveness of nitrification inhibitor or both urease and nitrification i.e. double inhibitors on reducing N losses in a rainfed spring-wheat (Triticum aestivum L.) system. Our findings suggested that amending urea with double inhibitors might be an effective strategy to reduce all possible N losses without compromising crop yields from urea-fertilized soils. The second study was conducted to understand the responses of spring-wheat to sulfate-based salinity stress under greenhouse and field conditions. R
