THE EVOLUTION OF SOME PEDO-CLIMATIC PARAMETERS, DEFINING ELEMENTS OF ADAPTATION STRATEGIES OF AGRICULTURAL SYSTEMS TO THE EFFECTS OF CLIMATE CHANGE

Abstract

The main purpose of our research was to accumulate as much scientific data as possible, regarding the properties of the soil (physical, chemical and hydrophysical) of the various types of soil, necessary to establish strategies for adapting agricultural systems to the effects of climate change, through a complex approach of physical-geographical and climatic-edaphic conditions in the Western part of Romania, respectively, the Mure?-Gala?ca Plain. Its general objectives consist in the accumulation of scientific data, necessary for the foundation of certain technologies of culture, for the wide diversity of cultivated species and varieties intended to ensure the conservation of the edaphic cover and sustainable management of soil and water resources and adaptation of agricultural systems to the effects of climate change. The reference area includes an area of 113079 ha, from which 103531 ha agricultural lands that are part of the Aranca Plain and the Galatca Plain, as a component part of the Mures Plain. This is due to the locationat the interference between the low plain and the high plain, from the former Mures delta, presents varied geological and physical-geographical conditions, which conditioned the formation of an edaphic coverrepresented by several types of soil, such as: psamosols, alluviosols, chernosols, pelosols, vertosols, salsodisols. That area, during an agricultural year, it usually presents two extreme situations, respectively: excess humidity in the cold season and deficit humidity in the warm period of the year. Both situations generating a series of forms of water stress with negative effects on the productivity and quality of agroecosystems.
