INFLUENCE OF CLIMATE CHANGE ON MANAGEMENT OF BULGARIAN AGRICULTURAL CROPPING SYSTEMS

摘要

Bulgaria is a part of EU market. For our country, along with the main agriculture crops as wheat, corn, sunflower, vegetables crops give a look of intensive agricultural production. Horticulture is situated at the interface between agroecosystem and society. In this point of view is very important to establish the relationship between change of climate conditions, management of agricultural cropping systems and soil quality with special emphasis on soil biota. Soil food web includes plants and other organisms that occupy different positions in the food chain which are linked by multiple ecological networks. The climatic conditions of the arable land in Plovdiv region were determined since the beginning of this century. A trend towards a lasting increase in the average monthly temperature in summer and fall of absolute minimum air temperatures during the winter months was established when it is compared with the climatic norms of the 20th century. We determined an increase in annual rainfall and dynamic change in their distribution seasons and in different years, for example 2014 there is an increase of 400 mm to the annual amount of rainfall. On the base of scientific knowledge about a new trend of challenges in sustainable agricultural production mitigating climate strategies could be promoted.
