Results and conclusions
USAMV IAŞI

The study of the questionnaires showed that:

• In Iaşi area:
• The owned fields have reduced areas (2-5 ha), and they are meant especially for field cultures (75%);
• Pasturelands have a significant ratio in the region, with relatively high productions 3-4 t/ha and they ensure the fodder necessities;
• Only 33% fertilize the pasturelands with manure;
• The surfaces occupied with permanent pasturelands in private property are relatively small in the area, less than 25% of all, the biggest occupied surfaces being those of the district's shared pasturelands;
• In Pojorâta and Vatra Dornei area:
• Fertilization is made generally with manure manually applied;
• The applied maintenance and exploitation technique for pasturelands is therefore simple and the productions are small, of 2-3 t/ha;
• The owners have a small number of animals (2 UVM);
• The maintenance works target pest control, wood vegetation control, manually executed.

The experimental area is characterized by:

• From the geographical position's point of view, the Ezăreni farm is set between 47°5'- 47°10' latitude north and 27°28' -27°33' longitude east. The Moldavia's Plain relief has a wide-spread wavy aspect, with hilly interspaces, with a shape of low plateaus. The forms have smooth edges, with long slopes towards south and south-east, having only one rough ravine towards north and north-west and the valleys are wide;
• The actual relief of Ezăreni farm is integrated in the geo-morphological general aspect of Moldavia' Plain. The biggest part of the farm's surface contains large plateaus with medium altitudes of 100-130 m and slopes of 2-4%. The highest altitude is of 170 m (Nut-tree Hill), and the lowest altitude (60 m) is in the Ezăreni small river valley;
• The hydrological web is represented by some slopes which constitute gathering paths of the surface's water supplies after massive rain-falls or after meltdowns. The Ezăreni small river, which flows into Nicolina river, is the most important water course with irregular water flow. Due to the torrential hydrological regime, this is maintained constant by two accumulating water ponds;
• The Iaşi geographic zone is characterized by a temperate climate with features influenced by the Russian steppe climate;
• The Ezăreni farm is part of the climatic area Dfbx (after Koppen's systemization), or IIDps (after Romanian Clime) and it is characterized by boreal clime, with cold frosty winters, with the coldest month's temperatures under -33°C and the hottest month's temperatures of 27°C;
• The "de Martone" dryness factor is between 26-30, according to the forest-steppe climatic conditions influenced by the Azorean anticyclone;
• The average multi-annual temperature is 9.4°C, with a minima of -8.1°C registered in January, and a maxima of 28.4°C registered in July;
• The average multi-annual rain-falls' values in Iaşi area are of approximately 529 mm, the rainiest months being May, June, July and August.

The study of the biodiversity showed that :

• There were evaluated the main pastureland types from the nemoral and boreal floor, in Iaşi and Suceava districts, and after that they were appreciated from the agronomical and qualitative point of view;
• The most valuable are the ones dominated by Festuca rubra and Agrostis capillaris species which have an average to good pastoral value and this determine a pasturing capacity of 1.0 - 1.2 UVM/ha. The fields of Festuca rubra with Nardus stricta and of Nardus stricta have a low pastoral value and a diminished pasturing capacity, under 1 UVM/ha;
• For the agronomical and nutritional value's study of the area's main pasturelands types there were placed three experimental devices, at Ezăreni - Iaşi, Pojorâta and Vatra Dornei;
• The flora and the vegetation from the studies perimeters wear the mark of the climate, of the edaphical conditions and also of the traditional way of land exploitation;
• The researches conducted on these pasturelands tried to give an overlook on the mountain natural pasturelands the way Europe considers them, in equal measure as fodder source and support of specific wealth with major implications in the local and regional landscape.
