Abstract
NUMEROUS tests have been proposed for determining the “available” nitrogen in soils, but although they have proved successful under some conditions, they have not generally been reliable for predicting field crop response1–3. Most of these methods are based on the estimation of nitrogen which can be readily hydrolysed by dilute acids1 or mineralized by incubation over short periods of time3. It seems quite probable that nitrogen left in more resistant fractions of soil organic matter may also play a supporting part in supplying nitrogen that can be used by plants. Recent research at this Station indicates that more vigorous acid hydrolysis and extraction of soil releases considerable nitrogen from resistant organic complexes.
