Effects of nano iron oxide powder and urban solid waste compost coated sulfur on chemical properties of a saline-sodic soil

effects of nano iron oxide powder and urban solid waste compost coated sulfur on chemical properties of a saline-sodic soil

the main limiting factors in saline-sodic soils are high amounts of salts, low soil organic matter (som) and lowavailability of macro and micro-nutrients. the effect of different amounts of nano iron oxide powder and urban solidwaste compost coated sulfur (uswcs) on the chemical properties of a saline-sodic soil was investigated. the experimentwas conducted using a randomized complete block des...

Applying Biochar and Mineral Amendments to Remediate the Chemical Properties of a Saline-Sodic Soil

The present study was intended to improve the chemical properties of a saline-sodic soil using the individual application of alfalfa residue and two biochars produced from sugarcane bagasse and walnut shell, at the weighting ratio of 5%; their concomitant application with gypsum, aluminum sulfate and the mixture of these two chemical amendments was considered. The experiment was conducted in th...

environmental effects of gol-e-gohar iron ore mine on groundwater of the area

gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...

Effect of Urban Waste Compost Leachate on the Soil Physical, Hydraulic, Moisture Characteristics and Corn Yield

Compost leachate is a liquid resulting from physical, chemical and biological decomposition of organic materials. The main objective of this study was to evaluate the influence of leachate compost on the physical, hydraulic and soil moisture characteristic curves. Also, the effect of leachate on the aerial organ fresh weight of corn was investigated. Leachate was added to clay loam and sandy cl...

Efficiency of sulfur application with different sizes and rates in reclamation of a saline-sodic soil in laboratory columns

extraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties

آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
