Data represent the mean ± standard error. Values with different letters mean significant differences (p < 0.05) according to Duncan’s test. Treatments ^a: RB = rice bran; FM = fishmeal; RSE = residual strawberry extrudate. The first number corresponds to the number of t/ha amended and the second number to the treatment duration (25 or 60 days). Data of CFU/g soil of Trichoderma spp. ^b, Streptomyces spp. ^d and copiotrophic bacteria ^f after treatments, and Trichoderma spp. ^c Streptomyces spp. ^e and copiotrophic bacteria ^g after plant trials were transformed for statistical analysis as x^0.3, x^0.3, x^-0.4, x^0.4, x^0.5, and x^0.7, respectively. n = 6 for all variables.
