Grass-matrix age and fallow-age effect on species groups pooled for the two study years. Lower-case letters indicate significant differences (comparison with emmeans, p ≤ 0.05). Boxplot lines represent median values. G + D—plots sown with grass and diverse forb seed mixture, D—plots sown only with diverse forb seed mixture, G—plots sown with grass (F. pseudovina) seeds. Numbers indicate the age of the grass-matrix or fallows when diverse forb seed mixture (D) was added.
