Changes in the agrochemical indices of Luvic Greyzemic Phaeozems under the impact of west Ukraine climate aridization

Abstract

Modern agriculture has not been so strongly affected by the climate change we are seeing today. There are no systematic studies and predictions regarding the response of soils to rising air temperatures and changes in the water supply of landscape ecosystems. Ultimately, it is unknown how climate fl uctuations affect the balance of nutrients and humus in soil depending on the crops grown. There is not enough scientifi c data to indicate that warming or aridization affect the effi ciency of plant fertilizers. Our aim is to fi nd out how changes in the climate of the Western Ukrainian mesoclimate interacts with the trends in soil processes and crop yields in the Northwestern Forest- Steppe. We analysed the weather data from 1945–2018 provided by the Rivne State Weather Station (Ukraine) and the crop yields of the Main Directorate of Statistics of Ukraine in Rivne region. Field studies were conducted in the conditions of the Northwestern Forest-Steppe of Ukraine during 1960–2018 at the stationary fi eld experiments of the Luvic Greyzemic Phaeozems (WRB. 2015) of the Institute of Agriculture of the Western Polissia of NAAS (Ukraine).
