Description Non-edible oil seed cakes and their constituents have been advantageously used
for increasing the efficiency of fertilizer nitrwen (Nj for cro8 production. The beneficial effccts of these materials have been attributed to retar a~ion of nilrification, which
lessen the loss of N associated with nitrification by leaching and den~trification in
situations where them losses are high. However, it is possible that some of the, effccts
of thcse materia Is could be due to immobilization-rcmineralization of N part~cularly
when the carbonaceour materials are added with fertilizers at high rates. A methodology
involving the use of lbN-labelled fertilizers is advanced to sort out whether the beneficial
effects of non-edible oil seed cakes and other materials are due to retardation of
nitrification and or immobilization-remineralization of fertilizer N. Using the proposed
technique it would be possible to make realistic evaluation of the wealth, of indigenous
products as nitrification inhibitors. Following the proposed approach ~t would also bo
possible to widen the scope and dc th of research in this area for ultimately better
exploitation of indigenous materia Is' as nitrification inhibitors.
