Previous studies have demonstrated that the toxic effects of 2,4,5trichlorophenol (2,4,5-TCP) are greater in agricultural soils than in forest soils; therefore these effects appear to be influenced by the total C content and soil pH. Agricultural soils (usually low in organic C) contaminated with 2,4,5-TCP may be able to be remediated by the addition of organic waste products. To test this hypo...

This experimental study was conducted at the Fruit Research Institute, Cacak, Serbia, to determine bud break and callus formation dates, the degree of callus formation, grafting success on day 20 after grafting and overall grafting success on day 28 after grafting in walnut (Juglans regia L.) under different treatments and bench grafting conditions in cultivar Seinovo (control) and the selectio...

Three experiments were conducted to determine the concentrations of phenolic monomers (para-coumaric acid, ferulic acid, vanillin, acetovanillone, para-hydroxybenzaldehyde and para-hydroxyacetophenone) and polymers (lignin) in roughages and to assess the fate of these compounds in the ruminant digestive system. In Exp. 1, low quality t imothy hay and cottonwood, silver maple and red oak sawdust...

In this paper, application of sawdust prepared from Narra wood (SD) modified with cationic surfactant of cetyltrimethylammonium bromide (SD/CTAB) was used for removal of two typical acid dyes commercially named as Acid Green 25 (AG25) and Acid Red 14 (AR14) from aqueous solutions. The effects of experimental variables, such as pH, initial dye concentration, adsorbent dose, contact time and temp...

Cross-linked and quaternized pine sawdust was tested for vanadium removal from a synthetic aqueous solution as well as from real industrial wastewater which had a considerable amount of vanadium and other ions such as sulphate, ammonium and nickel. The maximum vanadium sorption capacity of the modified pine sawdust was found to be 130 mg/g in synthetic solution and 103 mg/g in real wastewater. ...

Although many outlets are available for the utilization of wood fines, economical disposal of sawdust, shavings, and waste chips remains a problem of growing concern to the wood industry. This report summarizes current uses for wood residues and provides sources of further information on available outlets, processing methods, and economic considerations. USES FOR SAWDUST, SHAVINGS, AND WASTE CHIPS

Cotton is one of the most important fibre plants with much more products being manufactured from it than most other fibre . Apart from fibre, it is used for explosives, cottonwool, etc, and the seed is used principally for the manufacture of oil, soap, animal feed and fertilizers, producing practically no waste. To determine the effective sawdust concentration to inhibit the growth of Rhizocton...

Lentinus edodes (Berk.), the shiitake mushroom, is worldwide one of the most widely cultivated mushrooms. Sawdust is the most popular basal ingredient used in synthetic substrate formulations for producing shiitake spawn. However, the best sawdust for this uses needs to be determined. Shiitake mushroom was cultivated on sawdust from the woody plants Babla (Acacia nilotica L.), Champa (Michelia ...

Grifola frondosa is an economically important edible and medicinal mushroom usually produced on substrate consisting of sawdust supplemented with wheat bran. Cultivation of G. frondosa on crop straw (corn cob, corn straw, rice straw, and soybean straw) as a substrate was optimized by using the D-optimum method of the simplex-lattice design, and the alternative of crop straw as a substitute for ...

Cow dung slurry containing a total of 7.4 10 5 E. coli was applied to laboratory-scale microcosms of Pinus radiata sawdust or bark. Rainfall was simulated by application of water at rates of 25 mm h -1 or 50 mm h -1 over 30 minutes. For sawdust 5% and 11% (respectively) of the E. coli were transferred to drainage compared to 12% and 28% for bark. After collection of drainage less than 10% of th...
