В настоящее время две трети площади пашни и половина площади луговых земель характеризуется оптимальным и высоким уровнем содержания подвижных форм калия. Однако отмечена большая пестрота содержания подвижных форм калия в пахотных и луговых почвах ряда районов Беларуси. Обоснована необходимость увеличения ресурсов калийных удобрений в районах с преобладанием потенциально плодородных суглинистых почв и снижения накопления невостребованных запасов подвижных форм калия в песчаных почвах. Предложены дифференцированные нормативы среднегодовых показателей баланса калия для оптимизации обеспеченности пахотных почв калием по районам республики.</p></abstract><trans-abstract xml:lang="en"><p>The results of Agrochemical Soil Survey for 50 years showed the 3 times increase of mobile K-supply of arable soils and grassland in Belarus. The 2/3 of arable soils square and ½ of grassland are characterized with optimal or high level of mobile K content. At the same districts of country the needs for improvement of K-fertilizer supply of potentially fertile Luvisol clay and loam soils are evident, as well as reduce the K-supply of poorer sandy soils with higher mobile K content. Differentiated norms of K-balance accordingly of initial mobile K content of different textured soils are proposed.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title></ref-list><fn-group><fn fn-type="conflict"><p>The authors declare that there are no conflicts of interest present.</p></fn></fn-group></back></article>
