The conventional blocks of  oranges were treated with up to nine herbicides and four insecticides.  Weeds were controlled in the organic trees  with cultivation, and insects were controlled with neem oil and pheromone  traps.

Interestingly, the team  reported few differences between the conventional and organic oranges at the  time of picking, although the organic fruit was marginally smaller and  contained 13% more Vitamin C.  But in the  juice, the team reports that organically grown mandarin oranges produces juice  that:

  • Is more intensely  colored, and has a superior aroma and taste,
  • Contains higher  levels of all eight minerals studied (in three cases by 50% or more),
  • Has a 40% higher  concentration of total carotenoids (Vitamin A).
