Table 2 Diversity indices calculated from bacterial DGGE profiles associated with pot-grown olive trees fertilized with sheep black wool residues, BW, used at 4 different BW/soil percentages

From: Impact of sheep wool residues as soil amendments on olive beneficial symbionts and bacterial diversity
