Development of an organically certifiable growth medium for N-fixing cyanobacteria in a raceway biofertilizer production system
MetadataShow full item record
The on-farm cultivation of N-fixing cyanobacteria in raceway ponds may provide an alternative N source in organic farming systems. The cultivation of cyanobacteria in an organic farming system requires an organically certifiable growth medium. Additionally, efficient cyanobacterial cultivation depends on production methods that reduce the severity of the three growth limiting factors present in outdoor raceway cultivation: inefficient solar irradiance, growth medium nutrient depletion, and day-night temperature fluctuations. The purpose of this work was two-fold, first to develop and test an ...
