TOTAL NITROGEN STORAGE IN A Dichanthium ischaemum (L.) Roberty MEADOW

Abstract

Nitrogen is an indispensable nutrient for plant growth, as it allows plants to produce proteins, chlorophyll, enzymes and vitamins. That is why it is the main factor for the growth of the plant, also determining its quality. Thus, effective methods of improving the nitrogen stock in the soil must be found. The researches carried out in the 2023-2024 agricultural year, within the Solesti location of the Research and Development Station for Meadows, Vaslui, was represented by the analysis of the applied management, over-seeding with simple mixtures of fodder perennial grasses and legumes, on the the total nitrogen stock (N), namely the amount of nitrogen in soil and plants (from roots and dry matter production) on a Dichanthium ischaemum (L.) Roberty meadow. Climate conditions have a decisive effect on the accumulation of biomass and must be taken into account when interpreting the obtained results. In general, the agricultural year 2023-2024 was rainy, but with an uneven distribution, affecting the growth and development of plants. The studied meadow had a vegetation structure dominated by species with very poor fodder value. The effect of over-sowing has manifested itself not only on the quality of grassland vegetation, but also on the amount of total nitrogen accumulated. Between plant production, root production and the amount of nitrogen accumulated there was correlation.
