Maneb is a broad spectrum fungicide, often reported as a carcinogenic, teratogenic and neurodegenerative agent. Thus, the occurrence of maneb at non-targeted sites is a cause of concern. The present study investigates adsorption– desorption behaviour of maneb in the agricultural soils to know its fate, mobility and availability in the soil. The sorption study was carried out by batch equilibrat...

abstract: when pesticides are present in high concentrations in the environment causing ‎irreparable, metabolic, physiologic and structural damage on the organisms. diazinon and ‎deltamethrin are of the most widely used agricultural pesticides in the northern iran that can ‎enter aquatic ecosystems. anatropous fishes like kutum have most reactions with pollutants ‎because of their spawning in t...

This study examined the effects of soil physicochemical properties (including heavy metal pollution) and vegetation parameters on soil basal respiration, microbial biomass, and the activity and functional richness of culturable soil bacteria and fungi. In a zinc and lead mining area (S Poland), 49 sites were selected to represent all common plant communities and comprise the area's diverse soil...

General guidelines to reclaim saline or sodic soils do not adequately consider variables such as pH and the presence of organic matter that are known to affect soil stability. Poor structural stability of sodic, saline-sodic, and high-pH soils adversely influences crop yields; promotes piping, tunneling, and slope erosion; and can accelerate the failure of water conveyance systems. We evaluated...

cation exchange capacity (cec) is one of the main factors in monitoring and management of soil quality in order to achieve sustainable production. although cec can be measured directly, these measurements are difficult, time-consuming and costly, especially for aridisols. one alternative method is the use of pedotransfer functions (ptf), in which cec of soils is estimated through available soil...

application of phosphorus (p) fertilizers as solid or liquid fertilizers to soils leads to re-actions of orthophosphate ions with various soil components which remove p from the so-lution phase and convert it to less soluble phosphates. this study was aimed at determin-ing soil properties that affect the rate of phosphate retention in 28 contrasting calcareous soils from different geographical ...
