Phillipsite has formecl from volcanic glass in saline, alkaline lakes both saturated and undersaturated with respect to gaylussite and trona. It has also formed from volcanic glass in saiine, alkaline soils of Olduvai Gorge, Tanganyika. Phillipsite occurs both as lath,shaped and as equant crystals, which are commonly zoned lvith refractive indices ranging between 1.438 and 1.490. Molecular SiOz...

The diversity of Trichoderma spp. was investigated in alkaline soils of pistachio orchards at different geographic areas in Kerman province, Iran. A total of 161 Trichoderma isolates were obtained and identified at the species level by their morphological characters and sequence analysis of their internal transcribed spacer (ITS) and tef1-α genomic regions. Totally, five species of Trichoderma ...

limestone, exploited near bielawy, a town located in the kujawsko-pomorskie province ofpoland, is the main raw material in the production process in a cement plant. the dust emitted by the factory is of alkaline ph and contains such heavy metals as: cadmium (cd), lead (pb), chromium (cr) and nickel (ni). the research aims at assessing the influence of cement dust on the total content and bioava...

Abstract The data sources for the study were results of a continuous agrochemical (for 3 cycles) and soil erosion survey soils, as well official statistical data. period was characterized by an increase in content organic matter 0.35%, alkaline hydrolyzable nitrogen 20 mg/kg, pH acidity degree 0.15 units, reduction amount medium acidic soils 16.4%. It found that on poorly eroded decreases 0.4%,...

The objective of this work is the pedological characterization soils in watersheds Oueds Nekôr and Ghiss. Several profiles were identified sampled for Physico-chemical sedimentological analyses (color index, magnetic susceptibility, pH, granulometry, water content, organic matter, carbonates). question are roughly characterized by a soft diversified lithology, sparse vegetation cover, semi-arid...

The article presents the developed soil maps and of spatial variability properties (pH, total salt carbonate content, organic carbon, density) in some recreational areas Volgograd. anthropogenic soils studied include various urbostratozems (Urbic Technosols (Transportic)), Ekranic (Transportic), as well quasizems (Phaeozems (Tehnic)), among agrogenic ones – accumulation-carbonate agrozems (Camb...

in the present study, the diversity of trichoderma spp. was investigated in alkaline pistachio soils at different geographic area in kerman province, iran. a total of 161 trichoderma isolates were obtained and identified at the species level by analysis of their morphological characters and sequence analysis of their internal transcribed spacer regions of the rrna cluster and tef1 genes as phyl...

Newly created and restored wetlands play an important role in sequestering excess nutrients at the landscape scale. In evaluating the long-term efficacy of nutrient management strategies to increase wetland capacity for sequestering P, information is needed on the forms of P found across the upland-wetland transition. To assess this, we studied soils (0-10 cm) from four wetlands within cow-calf...

Rationale Take-all patch, caused by Gaeumannomyces graminis f. sp. avenae, is favored by alkaline soils. Because the calcareous sands used for putting greens in the Midwest have a high pH, bentgrass greens constructed with high sand content or to USGA specifications are especially prone to the disease. Previous research addressed take-all patch on established bentgrass greens and fairways with ...
