Evaluation of biochar from tea pruning residue and tea fluff compost utilization to alleviate soil chemical properties on an Inceptisol

Effect of dolomite and biochar addition on N2O and CO2 emissions from acidic tea field soil

A laboratory study was conducted to study the effects of liming and different biochar amendments on N2O and CO2 emissions from acidic tea field soil. The first experiment was done with three different rates of N treatment; N 300 (300 kg N ha-1), N 600 (600 kg N ha-1) and N 900 (900 kg N ha-1) and four different rates of bamboo biochar amendment; 0%, 0.5%, 1% and 2% biochar. The second experimen...

The Effect of Fruit Trees Pruning Waste Biochar on some Soil Biological Properties under Rhizobox Conditions

The pyrolysis of fruit trees Pruning waste to be converted to biochar with microbial inoculation is a strategy improving the biological properties in calcareous soils. In order to investigate the biochar effect on some soil biological properties of the soil in the presence of microorganisms, a factorial experiment was carried out in a completely randomized design in the rhizobox under greenhous...

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 ...

The Utilization of Aqueous Compost Fermentation Extracts (“Compost Tea”) for the Suppression of Turfgrass Pathogens

Compost Tea Effects on Production and Extraction of Nitrogen in Ryegrass Cultivated on Soil Amended With Commercial Compost

Numerous studies have demonstrated the potential of composted organic wastes not only as substitutes for peat as a growth substrate but also to stimulate plant growth and suppress soil-borne diseases. The major impediment to the use of compost as substrates or biocontrol agents has been variation in physical and chemical characteristics and disease suppression levels across and within compost t...
