Abstract
On forage lands overgrown with vegetation of low value for agricultural production, the postagrogenic transformation of the grass cover manifested itself in a decrease in the total projective coverage up to 1.7 times (compared with hayfields 94.8–99.0%) and heterogeneity of the species composition. The coefficients of floral similarity of haymaking Jacquard and forage lands with the curtin type of overgrowth averaged 0.45, and with the solid type – 0.39. Grass-cereal or cereal-grass stands were mainly composed of rhizomatous and turf-bearing plant species. The reserves of absolutely dry aboveground mass (4.86 t/ha) and carbon (2.04 t C/ha) of hayfields significantly exceeded (up to 1.5 times) the corresponding indicators of unused forage lands.
