Testing experimental model of drill for grasslands regeneration.

Grasslands are lands covered with permanent herbaceous vegetation composed of species belonging to several families of plants, especially grasses and perennial legumes, used as fodder or grazing. The current trend of worldwide research and in Europe in terms of permanent grassland, in conjunction with forecasts of global warming will affect climate and agro-forestry-pastoral background, is to maintain phytocenotic biodiversity of them. Grassland degradation is caused by the changes taking place in the living conditions of plants, vegetation structure, due, in large part, to climate change and their inappropriate management. When these changes are accompanied by reduced production or worsening of its quality, it is estimated that degrade the grassland. Harmonization assign factors to obtain high yields with environmental protection and economic efficiency in maintaining the grasslands, requires a complex scientific approach, targeting and differentiated technology application, adapted to the climatic and vegetation features based on scientific management, rational balanced, respecting the environment and biodiversity, using appropriate technical equipment. In this paper, experimental research consisted of work qualitative and energy indices determination of an innovative technical equipment performing regeneration of grasslands by narrow strips of soil processing and sowing directly into the grassy carpet of a mixture of herbs or even a single species, maintaining full or a certain percentage of existing vegetation. Tests were conducted in an experimental field consisting of a permanent grassland with low herbaceous vegetation cover, with a poor floristic composition and low percentage of clover, alfalfa and lolium. The experimental results obtained in this paper are used by farmers in the selection of technical equipment to meet the quality requirements of the EU market for rational exploitation and regeneration of degraded permanent grassland.
