Research about Adaptation of Agricultural Technologies for Successive Crops, in the Conditions of Current Climate Changes and Desertification Phenomena in South-Eastern Territory of Romania

ABSTRACT:
Recently, in the South-Eastern part of Romania, there has been a significant increase in the average annual temperature and a decrease in average rainfall, so that the phenomenon of desertification is more and more obvious, and agricultural crops are increasingly inefficient.
On the other hand, the pedological drought and the irrigations applied permanently, bring an increase of the content of soluble salts at the level of the plant roots, so that the technologies must be permanently adapted to the environmental conditions. An alternative is the use of green crops, which would bring a supply of organic matter to the soil, as well as the practice of successive crops, after the autumn crops. The paper presents the experimental results recorded in the agricultural year 2019 – 2020, regarding the use of successive crops at the Agricultural Research and Development Station of Braila, Romania, both for the main production and as green field, to increase soil fertility. Agricultural technologies should be continuously adapted to environmental conditions and farmers should primarily seek to preserve natural resources, namely soil fertility and groundwater purity, through technologies adapted to each ecosystem.
Keywords: double crops; soil fertility; water preservation; sustainability technologies.
