This study examines the leaching of aluminium from calcined kaolin (metakaolin) with citric, oxalic and lactic acid and binary combinations of these organic acids. The investigated parameters were the pulp density, acid concentration, pH, agitation speed, temperature and contact time. The kinetics of aluminium dissolution from metakaolin in binary organic acid mixtures were determined and ...
· The Truth About Nutrient Stewardship. Despite the (at times) shing headlines in mainstream press, it is hard to argue facts: Nutrient stewardship in American agriculture has been and continues to be a resounding success. After all, American farmers were applying the same or slightly more NPK in 1970 than they do today, yet our corn and soy ...
