cadmium absorption by tomatoes at different growth stages in polluted soil
environmental pollution by heavy metals is a growing global concern. most heavy metals accumulate in the top soil and in the long term, increased concentrations in the soil results in increased absorption and accumulation in plants. the usual concentration of cadmium in the soil is 0.001-2.4 mg/kg of dry soil. the level of absorption and accumulation in plants depends on the type of plant, tiss...
متن کاملEffects of Compost and Lime Application on Soil Chemical Properties, Soil Microbial Community, and Fusarium Wilt in Florida-grown Tomatoes
Soils used for vegetable production in Florida are sandy, have low organic matter content and fertility, and can support the growth of soil-borne pathogens. Some growers choose to apply compost as an antagonistic suppression approach to combat soil-borne disease effects on crop yields or to increase organic matter and improve soil fertility. The objective of this on-farm study was to determine ...
متن کاملEffects of Soil Moisture and Nickel Contamination on Microbial Respiration Rates in Heavy Metal-Polluted Soils
Soil microorganisms may be both sensitive and resilient to various disturbances. The effects of a single stressor on soil microorganisms have been well studied, but only limited research has been carried out to test the effects of simultaneous action of diverse stressors. Soil samples were collected from a long-term polluted zinc and lead site and an unpolluted site. Modeling studies assumed sp...
متن کاملZinc contamination decreases the bacterial diversity of agricultural soil.
Abstract Around half a million tonnes of biosolids (sewage sludge dry solids) are applied to agricultural land in the United Kingdom each year, and this may increase to 732 000 t by 2005/6. The heavy metals contained in biosolids may permanently degrade the microbial decomposer communities of agricultural soils. We used amplified ribosomal DNA restriction analysis of the extractable bacterial f...
متن کاملFrequency of Bacterial Frequency of Bacterial Contamination in Traditional Ice Cream Produced in Arak, Iran (2011)
Abstract Background and Objective: Ice cream is a suitable environment for microbial growth due to its chemical structure, ingredients, and its increased supply and demand. In the absence of hygienic considerations, it can cause poisoning. This study aimed to determine bacterial contamination in traditional ice cream produced in Arak city in 2011. Material and Methods: The samples (n= 30) were ...
