Nickel is a heavy metal which is a stable soil pollutant which is difficult to remediate. An attempt to reduce its impact on the environment can be made by changing its solubility. The right level of hydrogen ions and the content of mineral and organic colloids are crucial in this regard. Therefore, methods to neutralise heavy metals in soil are sought. There are no reports in the literature on...
Self-assembly is a ubiquitous physicochemical phenomenon. It is inherent to molecular recognition effects in the biological domain, and thus presents a basis for understanding the constitution and dynamic organization of living beings. However, it is argued in this paper that the very notion of self-assembly presents an incorrect and misleading one for the physical effects that it stands for. S...
Due to the harsh environmental conditions in arid and semi-arid area of country, it is essential to assess the factors affecting the vegetation in such areas. This study aimed to investigate the effect of some soil physicochemical properties (including texture, bulk density, moisture, organic matter, carbon, nitrogen, potassium, lime, sodium, electrical conductivity and pH) on Haloxylon persicu...
Soil temperature and moisture are widely-recognized controlling factors on heterotrophic soil respiration (Rh), although they often explain only a portion of Rh variability. How other soil physicochemical and microbial properties may contribute to Rh variability has been less studied. We conducted field measurements on Rh half-monthly and associated soil properties monthly for two years in four...

در سال های اخیر توجه زیادی به مدیریت زمین کشاورزی برای کاهش، co2 اتمسفر شده است. نوع استفاده از زمین عامل موثر بر ذخیره مواد آلی خاک مر باشد که بر کیفیت و کمیت مواد آلی ورودی، سرعت تجزیه بقایای گیاهی و فرایندهای مرتبط با پایداری مواد آلی اثر می گذارد. با این وجود، در مناطق خشک و نیمه خشک اطلاعات در مورد کیفیت و کمیت موادآلی خاک در رابطه با تغییر کاربری مراتع ناچیز است. بارندگی کم، حاصلخیزی ضعیف...
