STUDIES AND RESEARCHES ON THE PREPARATION OF THE GERMINATION BED WITH HEAVY DISC HARROWS

Agriculture has been around since ancient times and continues to be today a vital area of human activity. It remains the only source of food, an important supplier of raw materials for industry and also a significant market for its production. Agricultural ecosystems as an integrated organic complex of natural, economic and social factors, require the rational, scientific intervention of the farmer, leading to raising its productivity, its protection and profitability, based on superior parameters of contemporary technology, making full use of market economy mechanisms. The area occupied in our country by the soils with crops that are established in autumn is about 37% of the total agricultural area. The mechanization technology which includes tillage by removing the stubble and/or preparing the germinated bed on unplowed land, on which the autumn crops are established, it can be applied at a qualitative level corresponding to the agropedological requirements, at a low cost price and with low energy consumption, by using disc harrows.
