The Structure of International Exchanges in Agricultural Products Intended for Industry and Household Use in Romania

Determining the production and forage quality of a permanent grassland is essential for establishing the optimal stocking rate in order to preserve the biodiversity and the traditional landscape. The paper presents an assessment of the productivity of steppic grasslands from the two large geographical entities of the ROSCI 0201 North Dobrogean Plateau protected area, respectively Babadag and Casimcea Plateaus. The grasslands from the Babadag Plateau have undergone an accelerated process of degradation in the last 50 years due to the very large share of sheep and goats, almost 90% of the total grazing livestock, that graze all year round except for the days when the soil is covered with a layer of snow. The grasslands from the Casimcea Plateau have generally maintained their productivity for the last 45-50 years as the structure of the vegetal layer has been better preserved, a situation due to the 27% of the total livestock of cattle and horses that were maintained in the stable in the cold season. Currently, the grazing pressure exceeds carrying capacity of these steppic grasslands for 5.5 times in Babadag and 5 times in Casimcea, which is why it is necessary to balance the structure and number of livestock, expand fodder crops in arable land and implement more efficient management measures
