Uptake of ^<15>N from a blue-green alga (Nostoc sp.) by rice (Oryza sativa) was studied in pot and field experiments. Availability of ^<15> from blue-green algae incorporated into the soil ranged between 23 and 28% for the first crop and between 27 and 36% for the first and second crops. Surface application of the algal material reduced ^<15>N availability to 14-23% for the first crop and 21-27% for the first and second crops. The pot experiment demonstrated that for the first crop algal ^<15gt;N was less available than ammonium sulfate, but for two crops, its availability was very similar to that of ammonium sulfate. After two crops, 57% of ^<15>N from blue-green algae and 30-40% of ^<15>N from ammonium sulfate remained in the soil.
