摘要:Abstract(#br)Vernonia galamensis is a native weed of Ethiopia containing high concentration of naturally epoxidized oil (glyceryl trivernolate) in its seeds, which could be used as a potential substitute for currently used epoxy oils. Apart from an epoxy group, vernolic acid...

摘要:Abstract(#br)The sustainable use of P in agriculture, which is a non-renewable and strategic resource, relies on soil P tests. Traditional soil P tests, however, may not accurately assess plant-available P in soils ranging widely in properties. The main objectives of this wo...
