  7. 2012-01-01 While most of our network members are familiar with “moringa,” the moringa family (Moringaceae) actually contains many species. We have promoted the ever-popular M. oleifera, conducting our own taste-test trials to offer our network a more favorably tasting tree; we also work with the more...  
  8. 2015-01-20 To gain an understanding of the value of moringa prunings as a soil fertility input, we wanted to know the concentration of N, P, and K in woody versus leafy biomass of moringa trees. Plant tissue was collected at the second leaf harvest, about 2 months after the final manure application.
