Dynamics of Productivity and Botanic Composition of Longevous Pastoral Plant Stands on Peat Soils

Abstract

The long-term investigations have shown the high stability of meadow plant stands on peat soils and capability of maintenance of the productive longevity without reseeding for at least 20 years. Among perennial grain grasses, awnless brome, common foxtail and smooth meadow grass are featured by the greatest adaptive potential. The systematic application of mineral fertilizers is a guarantor of high productivity of the pastoral plant stands on peat soils, evenness of the harvest formation by year and pasturing cycle. At the high level of productivity of peat soils, the application of mineral fertilizers ensures its growth 1.7-2.5 times. Here, from 54.2 to 77.3 per cent of the growth is caused by the nitrogen fertilizers and the compensation of one kilogram of the active substance by the growth in the yield is 16.8-23.3 kg of the dry substance.
