A field study was conducted to assess the effects of soil tillage practices and straw management on soil CO2, and yield-scaled CO2 emissions in a rain-fed summer corn field on the Loess Plateau. Tillage treatments consisted of sub-soiling tillage (CP), no tillage (NT) and moldboard plow tillage (CT). Wheat straw was removed from half of the CP, NT and CT plots after harvest, allowing us to test...

The main results derived from the ozone pre-treatment of grain straw are shown. The use of ozone reduced acid insoluble lignin content in grain straw, whereas acid soluble lignin increased. This fact resulted in a more accessible structure to enzymes leading to higher enzymatic hydrolysis yield. Ozone consumption after 2.5 h reaction time was about 0.10-0.12 g/g DS, independently of the type of...

13 The purpose of the study was to investigate the influence of torrefaction on the grindability of wheat straw. 14 Straw samples were torrefied at temperatures between 200 ̊C to 300 ̊C and with residence times between 0.5 to 15 3 hours. Spectroscopic information obtained from ATR-FTIR indicated that below 200 ̊C there was no obvious 16 structural change of the wheat straw. At 200-250 ̊C hemice...

An important issue in the use of expert sys tems is the so called brittleness problem Ex pert systems model only a limited part of the world While the explicit management of uncertainty in expert systems mitigates the brittleness problem it is still possible for a system to be used unwittingly in ways that the system is not prepared to address Such a situation may be detected by the method of s...

paddy straw is one of the most abundant agricultural by-products in tamil nadu, india. itcontains high amounts of cellulose and lignin. the fungal strains were isolated from naturally decomposingsites of paddy straw. eight fungal strains were isolated and later these eight fungi were used for finding outtheir potential for the degradation of lignin and cellulose content of paddy straw. among ei...

Particleboard is a product of wood technology engineering made particles and other lignocellulosic materials which are bonded with synthetic adhesives. As an information, utilization natural adhesive for particleboard still limited. This study aimed to determine the influence hybrid from citric acid sucrose properties composed Sengon veener by-products sorghum stalk. The content used was 15% 25...

Development of insecticide resistance in onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), populations in onion (Allium spp.) fields and the incidence of the T. tabaci transmitted Iris yellow spot virus have stimulated interest in evaluating alternative management tactics. Effects of straw mulch applied in commercial onion fields in muck areas of western New York were assessed in ...

Two lamb trials were conducted to determine the effects of particle length (PL; 2.5 vs 10 cm) and sodium hydroxide (NaOH) treatment (0 vs 4%) of wheat straw on dry matter (DM) intake and site and extent of DM and neutral detergent fiber (NDF) digestion. Lambs in the first trial were fed ad libitum once daily. Lambs in the second trail were fed four t imes/d at 6-h intervals and were sacrificed ...

Current bioremediation techniques for petroleum-contaminated soils are designed to remove contaminants as quickly and efficiently as possible, but not necessarily with postremediation soil biological quality as a primary objective. To test a simple postbioremediation technique, we added earthworms (Eisenia fetida) or wheat (Triticum aestivum) straw to petroleum land-farm soil and measured biolo...
