Environmental protection study regarding the development of the ecological agriculture system

Résumé

The purpose of the paper is to reveal the development of plants grown both traditionally and environmentally friendly and to achieve a comparison of advantages and disadvantages of the two systems of agriculture. An essential aspect on which there is an emphasis with a view to the practical application of the organic farming system is the soil fertilization, given the fact that most of the problems that have made the necessity to convert to this type of agriculture are a consequence of soil  damage and affecting its quality. The researches have been performed on five species of plants grown in two systems of agriculture. The results obtained have a high theoretical and practical importance and reveal the importance of the organic farming within the framework of the activities of the environmental protection, even if the level of productivity is further reduced.
