An important percentage of Romania’s agricultural area is represented by degraded agricultural lands that can no nitrogen/ha/year) (Lu, 1992; Rajchal, 2009). Sea buckthorn (Hippophae rhamnoides L.) is longer be used for agriculture but can be ecologically and economically improved. One such method, respectively the The sea-buckthorn has been used for centuries one of the shrub species recommended for the use of shrubs, is supported by research conducted in Valea-Sării and Bârseşti experimental perimeters from Vidra in Europe and Asia and the latin name afforestation of fields that are highly degraded Experimental Forest District, Vrancea County. Hippophae, meaning shining horse arrived and unproductive. Its fruits are requested in Sustained by the concept of agroforestry, this method is used for the improvement of the degraded lands. In comparison from ancient Greece, due to their leaves that pharmaceutical and alimentary purposes to with the ecological exigencies of forest species, there is a great diversity of degraded lands that are suitable for the culture of some species of shrubs. The most affected and unproductive lands (eroded land or landslide) can be improved were added to horse fodder, the result being name just a few. and enhanced by using sea buckthorn plantations (Hippophae rhamnoides L.). weight gain and shiny hair (Rongsen, 1992). The objectives of this article were to identify the categories of degraded fields that are suitable for the culture of sea In recent years, the importance and the MATERIALS AND METHODS buckthorn together with the used forestry amelioration technologies and to emphasize the ameliorative effects and the scientific interest in sea buckthorn have sea buckthorn culture’s efficiency in regard with site conditions. increased in Europe, not only for soil The investigations took place in areas destined The research has shown that mixtures of Scots pine (Pinus sylvestris L.) and European black pine (Pinus nigra Arn. ssp. nigra) with sea buckthorn or pine plantations on consolidated lands with sea buckthorn, led to significant increases protection, as well as for their fruits rich in to a permanent research regarding the degraded growth of pines compared to pure cultures of pine, as a result of enrichment in soil nitrogen due to the symbiosis with flavonoids, carotenoids, and vitamins, field’s afforestation technologies, namely in the mycorrhizal fungus (Frankia). The investigations realized on parcels created especially for the study of leakages potassium being the most abundant element of Valea-Sării and Bârseşti experimental and installed on pine and sea buckthorn cultures (Bârseşti perimeter) have proved that the precipitation water leakages all occurring minerals in berries (Chen, 1988; perimeters from Vidra Experimental Forest is of 4 up to 10 times lower in the degraded pastures and the erosion’s quantum is of 0.05-0.5 mc/year/ha in Tong et al., 1989; Zhang et al., 1989; Souci et District, Vrancea County. comparison with over 50 mc/year/ha, in pastures and empty fields. Beside their soil improvement and field stabilization role (by reducing leakages and erosion), the sea buckthorn cultures have also important economic benefits, as their al., 2000; Sabir et al., 2005). The research were made on permanent plots fruits that are highly valued in the pharmaceutical and food industries. The concept on which our proposed method (on two experimental perimeters) in forest stands is “agro-silviculture”.
