Abstract

It was shown that lowland rice responds unfavorably to situations in which the crop is forced to absorb its N as urea. This finding has to be taken into account when in lowland rice culture use is made of chemicals intended to retard the conversion of urea-N to NH4-N. It was furthermore shown that, contrary to what was reported for upland soils, nitripyrin (N-serve) failed to retard the denitrification of NO3 when applied to a submerged soil on which rice was grown.

Key words

denitrification inhibitor lowland rice nitrapyrin urea uptake urease inhibition
