This paper compared the effectiveness of four organic materials for decreasing the amounts of soil extractable Cr(VI) in Cr(VI)-contaminated soils using the DOWEX M4195 resin-extraction method. Organic matters were added into Cr(VI)-spiked soils [500 mg Cr(VI)(kgsoil)(-1)] in the form of sugarcane dregs compost (SCDC), cattle-dung compost (CDC), soybean meal (SBM) and rice bran (RB), in the amo...

Changes in physical and chemical characteristics of an organic waste (tomato crop waste) throughout composting (COM), vermicomposting (VER) and the combination of both processes (C+V) were assessed at five selected stages. COM consisted of a combination of the static Rutgers system with forced aeration and pile turning. For VER Eisenia worms were fed with the raw material. For C+V pre-composted...

background citric acid is produced in insignificant quantities in iran. despite its great range of utilizations, and from another aspect, high level of production of sugarcane bagasse, the related problems arising from maintenance of this acid require thinking of a measure in the direction of its optimal usage and production. objectives the objective of the present study is to obtain effectual ...

This study was conducted to determine the effect of compost and compost tea on growth and physiological parameters of Lepidium sativum L. 30-day-old Cress plants treated with compost and compost tea were harvested and different growth and physiological parameters were measured. Compost tea application increased RGR, SLA, ULR and RLAGR. The contents of Chlorophyll a and Chlorophyll b in the plan...

introduction: sugarcane (saccharum officinarum) is widely cultivated in south west of iran for production of sugar. after harvest, a lot of sugarcane tops remain on the farm that can be used to feed ruminants. the total digestible nutrients (tdn) and crude fiber of sugarcane top is about 72% and 39%, respectively. the digestibility of dry matter (54%) and crude protein (39%) of sugarcane top is...

this study was conducted to compare fungi and whole rumen microorganisms (wrm) digestibility of treated sugarcane pith by fungi and of buffalos and holstein cows. dry matter (dm), neutral and acid detergent fiber (ndf and adf) digestibilities of steam treated sugarcane pith (stp) by fungi and wrm were compared with a two-steps digestion technique, gas production (gp) and specific rumen fungi cu...
