Determination of carbohydrates in soil requires prior extraction and numerous extraction methods were suggested for this purpose. Three methods and five extractants were applied in order to extract carbohydrate fraction in three soil types forest, clayey and saline soils. The extraction methods were: 1) shaken in a plane rotary shaking machine for 16 h 2) heated in steam-bath for 2.5 h and 3) h...

Halomorphic (or saline) soils, are characterized by high concentrations of soluble salts or sodium, both. Saline soils have unfavorable agricultural properties but provide the natural habitats for a variety highly specialized plants, animals, and other organisms. It is these special interactions that create typical landscape saline known as “slatina”. The aim this study to assess evaluate geoto...

abstractbackground and objectives: in most saline and non-saline soils, nitrogen is the most restrictive nutrient for plant growth. in saline soils, interactive effects of salinity and soil fertility is very important from optimum production. nutrient imbalance is one of the problems with saline soils. in these circumstances, the fertilizer application may to increase osmotic effect of salt, th...

Abstract Statistical analysis of 3802 samples saline soils from different regions Russia made it possible to substantiate preliminary conclusions about a higher proportion magnesium in containing gypsum comparison with gypsum-free soils. Gypsum is not toxic salt and its presence does cause an increase salinity. Salinization mainly related sodium salts, the percentage often exceeding percentage....

BACKGROUND Salinity is known to affect almost half of the world's irrigated lands, especially rice fields. Furthermore, cyanobacteria, one of the critical inhabitants of rice fields have been characterized at molecular level from many different geographical locations. This study, for the first time, has examined the molecular diversity of cyanobacteria inhabiting Indian rice fields which experi...

Abstract Purpose Alkaline salinity constrains crop yield. Previously, we observed local adaptation of Arabidopsis thaliana to saline-siliceous soils (pH ≤ 7) and non-saline carbonate soils. However, no natural population A. was localized on saline-alkaline This suggests that tolerance evolved may not confer alkaline salinity. hypothesis explored by addressing physiological molecular responses d...
