Summary:
Limnological investigations were conducted on 21 oligotrophic British Columbia lakes. At weekly intervals during the growing season, 12 of the lakes were fertilized with ammonia nitrate and ammonium phosphate. Phosphorous loads from fertilizer were from 24 to over 200% above annual natural loads. Annual production in the lakes averaged 31 g C.m -2 and ranged from 14 to 73. Mean epilimnic chlorophyll concentrations  Read more...

Abstract:

Limnological investigations were conducted on 21 oligotrophic British Columbia lakes. At weekly intervals during the growing season, 12 of the lakes were fertilized with ammonia nitrate and ammonium phosphate. Phosphorous loads from fertilizer were from 24 to over 200% above annual natural loads. Annual production in the lakes averaged 31 g C.m -2 and ranged from 14 to 73. Mean epilimnic chlorophyll concentrations in mose lakes were between 1 and 2 mg.m -3. Response of the lakes phytoplankton communities to fertilization was quite variable, but production and biomass tended to be higher during fertilization. The response and variability are discussed with reference to annual variation in various physical, chemical and biological factors.
