Заглавие документа: Optimization of crop rotations based on geostatistical analysis of soil acidity and earth remote sensing data, taking into account financial costs Авторы: Kindeev, A.I.; Gytko, F.S. Аннотация: The article presents the possibilities of detailed analysis of the spatial distribution of soil acidity to reduce liming costs and optimise land use in five working areas of the experimental farm “Gutko S.”. Based on variogram analysis, the patterns of acidity distribution in key areas are determined. Regression analysis showed a significant and high polynomial dependence between the NDVI index and soil acidity (the correlation ratio is 0.60–0.75 at sites No. 2–4) and a significant direct linear relationship at site No. 1. Geostatistical analysis revealed an average spatial dependence (residual variance of 29.9%) at site No. 3. Based on the strong relationship between the average values of the NDVI index for the summer months over 3 years (9 images) and soil acidity, it was proposed to use NDVI as a predictor for optimising the sampling grid using stochastic modelling. It was found that the relationship with NDVI is more pronounced in areas where the relief is less fragmented. Based on calculations of costs for liming, the advantage of detailed acidity accounting over the classical methods of agrochemical survey used in the Republic of Belarus was substantiated. The profit per rotation was about 1,200 US dollars from an area of 184.5 ha. Based on the results of the analysis of acidity distribution, the NDVI index and field history, a more detailed scheme of elementary plots with crop rotations that take into account soil acidity was proposed. The limitations of the available agricultural equipment prevented a more detailed division of the plot.

Заглавие документа: Climate Change Affects the Vulnerability of Belarusian Lakes to External Impact Авторы: Sukhovilo, N.; Novik, A.; Vezhnavets, V. Аннотация: The investigation of lakes’ vulnerability to external impacts is essential for understanding and potentially mitigating the threats they face. By studying how lakes are affected by external factors, such as pollution, climate change and human activities, we can assess the health of the ecosystem and predict how it may respond to future changes. The purpose of this research is the analysis of climate change’s influence on the vulnerability of Belarusian lakes to external impact. The vulnerability indices were calculated using the randomized aggregate method. The dependences between parameters were defined on the basis of correlation and regression analysis. We investigated the vulnerability of 149 Belarusian lakes. Classifying the lakes allowed us to divide them into three types, with high, medium and low vulnerability to external impact. All the types include 2–3 subtypes. On the basis of classification, we created a zoning scheme for Belarus on the vulnerability of lakes to external impact. A forecast of lake vulnerability for three SSP scenarios to 2100 was conducted. In the SSP1 scenario, the vulnerability of stratified lakes will increase insignificantly. The vulnerability of homothermous lakes will not change. In the SSP2 scenario, the vulnerability of lakes will first increase then decrease. Lakes with high and medium vulnerability will be classed as medium- and low-vulnerable. In the SSP5 scenario, the vulnerability of lakes will decrease more significantly than in the other scenarios.

Заглавие документа: Миграция основных лесообразующих пород в муравинское межледниковье на территории Беларуси Авторы: Писарчук, Наталья Михайловна Аннотация: Представлены результаты анализа спорово-пыльцевых диаграмм отложений муравинского (микулинского, эемского, мяркинского, прилукского) межледниковья с использованием ГИС-технологий. Выделены входящие и исходящие миграционные потоки основных компонентов флоры (лесообразующие породы: ель (Picea A. Dietr.), сосна (Pinus L.), береза (Betula L.), дуб (Quercus L.), липа (Tilia L.), вяз (Ulmus L.), граб (Carpinus L.), ольха (Alnus Mill.), лещина (Corylus L.).) для 12 фаз развития растительности на протяжении муравинского межледниковья в пределах территории Беларуси. Анализ миграционных потоков указывает на трехкратный цикличный характер различной амплитудности изменений во флоре изучаемого периода.
