Grow plants that compete with damaging weeds
A controlled study in 2004-2008 in pasture land in the Strážov Hills, Slovakia (Vozár et al. 2009) found that the proportion of pasture covered by stinging nettles Urtica dioica was reduced by 91% after one season of cutting and reseeding with cock's foot Dactylis glomerata and white clover Trifolium repens. Cutting without reseeding reduced stinging nettle cover by 70% if cuttings were left as a mulch, or by 51% if cuttings were removed. Stinging nettles increased by 11% in an uncut and unseeded treatment. By the end of year five of the study, stinging nettles were rare in the cut and reseeded treatment, covered 1-2% of the pasture in the cut, unseeded treatments and covered 93% of the pasture in the uncut, unseeded treatment. Grass cover in the cut and reseeded plots was 84% by the end of the second year and remained between 68-92% for the rest of the experiment, compared to 3.7-43% in the cut, unseeded treatments and 0.3-6% in the uncut, unseeded treatment. Cut plots were cut every fifth week, starting when the ground cover was 250-300 mm high. The paper gives no further details of the study setup.
