Soil aeration is a crucial factor that regulates crop residue decomposition, and the chemical composition of decomposing crop residues may change the forms and availability of soil nutrients, such as N and P. However, to date, differences in the chemical composition of crop straw residues after incorporation into soil and during its decomposition under anaerobic vs. aerobic conditions have not ...

In 1890, 2 years before the term ^^hemicellulose" was introduced into chemical Uterature by Schulze (12) j^ Allen and ToUens (1) extracted wheat straw with alkali and obtained a product that on hydrolysis afforded ¿-xylose. In 1901 Salkowski (11) extracted wheat straw with boiling 6-percent sodium hydroxide solution and showed that the xylan could be precipitated from the alkaline extract by me...

This experiment was carried out to compare the effects of treated and untreated wheat straw with Pleurotus florida on ewe feed intake, nutrient digestibility, and ewe body condition score (BCS) after parturition. Thirty Kermani ewes with an average weight of 48 ± 3.05 kg and about four years old were used in this experiment. Synchronization of estrus in sheep has been achieved with the use of i...

Bulk density of comminuted biomass significantly increased by vibration during handling and transportation, and by normal pressure during storage. Compaction characteristics affecting the bulk density of switchgrass, wheat straw, and corn stover chopped in a knife mill at different operating conditions and using four different classifying screens were studied. Mean loose-filled bulk densities w...

The aim of this study was to investigate the influence of reaction temperature and wheat straw moisture content on the pyrolysis product yields, in the temperature range of 475-575 °C. Samples of straw with moisture contents from 1.5 wt % to 15.0 wt % were fed to a bench scale Pyrolysis Centrifuge Reactor (PCR). The experimental results show that the changes in straw moisture content have no si...

Waste materials have a strong potential in the bioremediation of oil-contaminated sites, because of their richness in nutrients and their economical feasibility. We used sewage sludge, soybean meal, and wheat straw to biostimulate oil degradation in a heavily contaminated desert soil. While oil degradation was assessed by following the produced CO2 and by using gas chromatography-mass spectrome...

A regional experiment was conducted at 8 experiment stations, with a total of 320 sows initially, to evaluate the efficacy of adding 13.35% ground wheat straw to a corn-soybean meal gestation diet for 3 successive gestation-lactation (reproductive) cycles compared with sows fed a control diet without straw. A total of 708 litters were farrowed over 3 reproductive cycles. The basal gestation die...

1. Groups of chicks were given a low-residue diet with or without supplements of dietary fibre in the form of wheat bran, wheat straw or bagasse. Growth and food conversion efficiency (g weight gained/g food eaten; FCE) during the first 4 weeks of life were measured. 2. In every one of seven experiments supplementation of the diet with 100 g wheat bran/kg resulted in improved growth, and in thr...
