Research ArticleOpen accessIn the abstractDensity Equation of Bio-Coal Briquettes and Quantity of Maize Cob in Phitsanulok, ThailandPatomsok WilaiponOne of the most important crops in Phitsanulok, a province in Northern Thailand, is maize. Base on the calculation, the quantity of maize cob produced in this region was approximately 220 kton year-1. The net heating value of maize cob was found to be 14.2 MJ kg-1. Therefore, the total energy over 874 TJ year-1 can be obtained from this … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,891 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Grazing Sorghum Stubble on Soil Physical Properties and Subsequent Crop PerformanceB.J. Radford, D.F. Yule, M. Braunack, C. PlayfordTwo grazing trials were conducted on a Vertosol in central Queensland to assess the effects of stubble grazing by cattle on soil properties and subsequent crop performance. Two adjacent contour bays were selected for two treatments (grazed and ungrazed) in each trial. Both trials were conducted following a grain sorghum crop. In trial 1 (during 1996) the surface soil was … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 4 · 31 Dec 2008 · 8,154 accessesView PDFCite

Research ArticleOpen accessIn the abstractCharacterization of Maturity Level in Laying Hen Manure by Chemical and Thermogravimetric AnalysisAlice Dall’Ara, Francesco Antolini, Laura Billi et al.This study aims at investigating maturity levels in manure from laying hens in order to encourage its agronomic re-utilization. In fact the use of unstable/insufficiently mature manure could potentially damage both soils and crops. Effective, easy to reproduce methods are needed in order to assess bio-stabilisation and maturity levels, particularly for biomass that has not undergone conventional composting. This study … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,540 accessesView PDFCite
