Soil mycorrhizal inoculum potential (MIP) of pot-grown olive trees fertilized with sheep black wool (BW) residues, used at 4 different BW/soil percentages

	Treatment	MIP (%)	Mycorrhizal colonization (%)
BW	C	44.3 ± 5.8a*	83.3 ± 3.3a
	0.5%	61.0 ± 8.5a	80.0 ± 5.8a
	1.0%	67.9 ± 10.6a	76.7 ± 3.3a
	2.0%	44.3 ± 6.6a	53.3 ± 3.3b

*Values (means ± standard errors of three replicates per treatment) followed by the same letter in a column are not significantly different at P < 0.05 (Tukey’s post hoc test)
