Study of phosphorus reactions over time and the role of organic matter in the calcareous soils are important for the development of P fertilizer and manure management practices. The objective of this study was to determine the effect of applied manure on P availability and its chemical forms in the soil, over time. Eight samples were collected from semi-arid calcareous soils of Mashhad plain. T...

In this study, five microbes were employed to precipitate calcite in cohesionless soils. Four microbes were selected from calcite-precipitating microbes isolated from calcareous sand and limestone cave soils, with Sporosarcina pasteurii ATCC 11859 (standard strain) used as a control. Urease activities of the four microbes were higher than that of S. pasteurii. The microbes and urea-CaCl₂ medium...

Genus Mentha is represented by 15 taxa in Turkey, most common being Mentha longifolia, M. suaveolens, M. pulegium and M. aquatica. All are perennial herbs, flowering in summer and reproducing with the help of seeds as well as vegetatively. These taxa are widely used by locals as condiment as well as for the preparation of mint tea aginst flue, lung and stomach disorders, whooping cough, and as ...

Abstract This study provides the first contribution to knowledge of non-calcareous grasslands arenaceous sector Monti Sibillini National Park (central Italy). We conducted 55 relevés using Braun-Blanquet phytosociological method and analysed ecology plant communities by Redundancy analysis topographic variables Ellenberg Indicator Values as predictors. identified nine communities, belonging fou...

In this research, several chemical extractants and modified Olsen methods were studied in 25 surface-calcareous soils (0-30 cm) for determining available phosphorus (P) for corn (Zea mays L.) plant. In this experiment, the highest correlation was obtained between extracted P by Olsen and Colwell methods (NaHCO3-extractable P) and dry weight of corn shoot (r =0.67 and 0.75, p

Organic manures can affect phosphorus (P) sorption characteristics (PSC) and its availability in soils. Information about effect of sewage sludge (SL) on PSC in calcareous soils of Hamadan province is limited. The objective of this research was to study the effect of SL on PSC and available P in 10 calcareous soils. The soil samples were incubated with and without 1.5 % SL for 5 months at field...

Ethylenediaminetetraacetic acid (EDTA), nitrilotriacetic acid (NTA), and other synthetic polycarboxylic acids have been shown to possess substantial capacity as washing agents of heavy metal-polluted soils, but they are environmentally problematic. Therefore, a sample of natural soluble humic substances (HS) was tested as a possible substitute. The efficiency of HS to extract cadmium (Cd), copp...

Assessing the ability of soil microorganisms to dissolute poorly soluble native calcite to supply Ca2+ is a new area to be explored in reclaiming sodic soils by supplying adequate Ca2+ and reducing the recurrent sodicity. Hence, the present study aimed to isolate a calcite dissolving bacteria (CDB) from calcareous sodic soils and to understand the mechanism of calcite dissolution. Of the 33 CDB...
