this study investigated the variation between two sugar beet (beta vulgaris l.) cultivars with respect to growth parameters and photosynthetic rates of individual attached leaves during salinization. sugar beet plants grown in sand culture were gradually exposed to different levels of salinity (0, 50, 150 , 250, and 350 mm, nacl+cacl2 in 5:1 ratio). salt concentrations significantly decreased a...

Management of irrigation and fertilization in greenhouses, if not done correctly, can cause soil salinization. The use water treated with very low-frequency electromagnetic resonance fields (WVLF) reduce salinization effects on the photosynthetic biometric systems. Thus, purpose research to evaluate metabolism photosynthesis impact WVLF cultivation tomato crops subjected different levels fertig...

Research on the variation in soil water, heat, and salt unsaturated zones during freeze–thaw process has great significance efficiently utilizing water resources preventing salinization. The field experiment was carried out with lysimeter as test equipment to analyze characteristics of process, profile content, main ion content three textured soils groundwater table depth 0.5 m. results showed ...

Purpose: to analyze the experience of domestic and foreign scientists in using various types land reclamation restore increase fertility degraded soils under irrigation rainfed conditions. Discussion. The overview research papers, literary sources, concerning impact on restoration is presented. options for reclamation, depending type degree soil degradation are considered. timely application (h...

The climate of the Qinghai–Tibet Plateau is distinct. Given large temperature difference between day and night, drought in perennial years, low rainfall evaporation volume, frozen soil some areas will occur salt. presence salt changes water thermal characteristics soil, which affect its activity layer. In this paper, Beiluhe area was selected as research object, numerical calculation model wate...

Throughout the Mediterranean Region, recent and past studies have highlighted an increase in temperature, especially during summer, a decrease precipitation change in-year pattern [...]
