اثرهای ریزوسفری گندم (Triticum aestivum L.) بر قابلیت استفاده فسفر و برخی از ویژگی‌های بیولوژیک در خاک‌های آهکی دشت شهرکرد
The chemical conditions of the rhizosphere are known to considerably differ from those of the bulk soil, as a consequence of a range of processes that are induced either directly by the activity of plant roots or by the activity of rhizosphere microflora. Plant species have involved various adaptive strategies to acquire P from soil pools. Therefore, the objective of this research was to evalua...
متن کاملاثر شوری بر برخی شاخص‌های میکروبی خاک در حضور و عدم حضور ریشه‌های زنده گیاه
Similar to plants, soil salinity may reduce microbial growth and activities in different ways. The aim of this study was to determine the effects of different levels of salinity on some microbial indices in the presence and absence of plant's living roots. In this study, five levels of salinity using NaCl, CaCl2, MgCl2 and KCl and three soil media (soil with no plant, soil cultivated with wheat...
متن کاملاثر علف‌کش ارادیکان بر کربن و نیتروژن توده زنده میکروبی و فعالیت اوره‌آز و آریل سولفاتاز در یک خاک آهکی تحت شرایط مزرعه‌ای
The application of herbicides as organic chemical compounds to control pest and weeds may affect the population and activity of microorganisms, and this may have an influence on biochemical processes that are important for soil fertility and plant growth. The primary objective of this study was to evaluate different loading rates of eradican (EPTC) on soil microbial biomass C and N, microbial b...
متن کاملEvaluation of cement dust effects on soil microbial biomass and chlorophyll content of Triticum aestivum L. and Hordeum vulgare L.
ABSTRACT: Overall plant growth and microbial biomass can be effected by dust accumulation. The chloroform fumigation-extraction method was used to evaluating the effect of cement dust pollution emitted from Kurdistan cement factory on soil microbial biomass carbon. Chlorophyll content (a, b and total) of plants species was measured in different distance from cement factory. Mic...
متن کاملروند تولید 2CO و تغییر کربن بیومس میکروبی در خاک‌های تیمار شده با کود اوره و مرغی
The addition of organic and inorganic substrates to calcareous soils low in organic matter and nitrogen contents may change soil microbial biomass and activity. In order to investigate the effect of chemical and organic fertilizers on soil CO2 production and microbial biomass C, a field experiment was conducted under maize cultivation. The experimental design was split-plot arranged in randomiz...
