PROTECTED AREAS MANAGEMENT IN AGRICULTURE AND FORESTRY

The paper presents the main objectives regarding the management of protected areas - "The protected area is a clearly defined geographical space, recognized, designated and managed on the basis of legal documents or other effective means, in order to achieve long-term conservation of nature and also ecosystem services and associated cultural values ". Managing a protected area is designated to protect a species or to encourage natural succession, to preserve a way of life or restore vegetation. Through the study of management was established the legal basis for protected areas, the priorities being the planning, relations with government and local communities, applying research and also current management tasks (monitoring agriculture, particularly forestry, maintaining trails, providing services for visitors, environmental education , training and perfecting the employees). Management of protected areas is a field that has just began to develop, starting with the establishment in 1992 of the Danube Delta Biosphere Reserve (DDBR)

STUDY REGARDING BIOCHEMICAL CHARACTERIZATION AND SOME PREPARATIONS FROM NETTLE AND WORMWOOD IN ORDER TO CAPITALIZE THEM AS BIOINSECTICIDE / BIOFERTILIZERS IN ORGANIC AGRICULTURE

Plant extracts contain substances that may induce, in treated plant, stimulation of defense mechanism, which will result in increased crop resistance especially against pathogenic microorganisms and pests that are causing the biggest economic losses and propagate the infection risk in time. Plant extracts are topics approached for a long time in support of organic agriculture, but still represents a generous particularly concerning on this essential aspect of a real organic agriculture. This paper is aimed at biochemical characterization of plant extracts of nettle and wormwood in order to capitalize them further as organic bioinsecticide / biofertilizers in organic agriculture. Extracts of nettle and wormwood are repellents and usually used preventative against pests, but also with economic advantages

CONSIDERATIONS REGARDING THE PROCESS OF COMPACTION AND SOIL LOOSENING

The soil works are a series of agrotechnical operations that modify the physical condition of the soil using mechanical means. The purpose of the soil work is to create optimal conditions for the crop in order to obtain harvests as large as possible, through soil works being able influencing both the content of air, water and soil temperature and nutrient content adjustment. This paper presents some considerations concerning the characteristics and the properties of soil, respectively the measures to be taken to reduce compactness
