A new technique was developed for the large-scale synthesis of lSN-labelled urea at low enrichment levels. The synthesis is based on nucleophilic displacement of the phenoxide ion from phenyl carbonate and uses anhydrouli Pmmonia as the nucleophile. In previous reports a copper catalyst was used; ho

A new 15N technique (termed the negative discard method) for measuring recovery of foliar-applied N by crops in the field is described. '5N-labelled fertiliser solution is sprayed on to a small area of crop, using a hand sprayer, while the surrounding area is sprayed with unlabelled N at the same ra
