Item type:Наукова стаття, Changes in the agrochemical indices of Luvic Greyzemic Phaeozems under the impact of west Ukraine climate aridization(Poland, 2022) Avhustynovych, MariyaModern 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).Item type:Наукова стаття, Influence of climate dynamics and liming on physicochemical soil properties and crop- rotation productivity of North-Western Polissya in Ukraine(Poland, 2022) Avhustynovych, MariyaTwo liming fertilizers for soil deacidifi cation in Polissya were investigated: dolomite and lime fl our, which were applied at the beginning of the 8-year crop rotation with medium fertilizer N112P82K105 between 2011 and 2019. The experiments were performed in a stationary fi eld trial by the Institute of Agriculture of Western Polissya of the National Academy of Agrarian Sciences of Ukraine on crop rotation of winter wheat, corn, barley and winter rape. The object of the research was Albic Retisol (Arenic, Aric) (WRB, 2014) in a stationary trial. Before starting the research, soil pHKCl was 4.3 and hydrolytic acidity (Hh) 2.80–2.97 cmol(+)·kg–1. Liming fertilizer doses were determined on the basis of soil hydrolitic acidity (Hh) for dolomite fl our: 0.5 Hh – Dd0.5 2.230 t∙ha–1; 1 Hh – Dd1.0 4,740 t∙ha–1; 1.5 Hh – Dd1,5 6,700 t∙ha–1 and lime fl our: 1 Hh – Dl1.0 4,940 t∙ha–1. Application of dolomite fl our at a dose of Dd1.5 6,700 t∙ha–1 proved to be the most effective. It neutralised the acidity of the soil to the highest level pHKCl (6.64) and maintained in this case pHKCl 6.04 until the end of the 8-year of crop rotation. 3D modeling showed that the effectiveness of soil deacidifi cation by dolomite fl our increases with moderate simultaneous climate warming and humidifi cation.
