В то время как, почвы правобережья реки Ачиджаи образованы на четвертичных аллювиальных отложениях, находящихся на террасе и поиме, почвы левобережья образованы из четвертичного аллювия, аллювиально-коллювиального материала и олигомиоце-новых гипсовых и соляных пластов, расположенных в поиме, террасе и на крутых склонах. Данные о своиствах почв с обеих сторон реки Ачиджаи свидетельствуют о значительных различиях их между собои в соответствии с почвенными процессами, в которых они были сформированы по их ландшафтному положению и исходному материалу. В соответствии с таксономиеи почв были определены 6 различных почв, которые были классифицированы как Entisol, Inceptisol и Mollisol вдоль разреза. Кроме того, было обнаружено, что изменения ландшафта, связанные с эрозиеи и содержанием органических веществ, могут влиять на деятельность почвеннои уреазы как в пределах профиля почвы, так и вдоль различных склонов.</p></abstract><trans-abstract xml:lang="en"><p>The main objectives of this study were (i) to determine physico-chemical properties of six different soils (ii) to measure the range and degree of urease activities, (iii) to evaluate the influence of soil physico-chemical properties on urease activities in the both sides of the £ankiri-Acifay River associated with specific landforms and different slope gradient. While right side soils of the Acifay River are formed on quaternary alluvial deposits that find on terrace and floodplain, left side soils formed from quaternary alluvium, alluvial-collivial material and oligo-miocene gypsum and salt strata located on floodplain, terrace and steep lands respectively. Soil properties data of both sides of Acifay River soils indicated significantly differences each other in terms of pedogenic processes which have been shaped by landscape position and parent material. According to soil taxonomy, 6 different soils were determined and classified as Entisol, Inceptisol and Mollisol along transect. In addition, it was found that changes of landscape positions associated with erosion and organic matter content can alter the soil urease activities within the soil profile and along different slope.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>soil genesis</kwd><kwd>soil landscape</kwd><kwd>soil enzyme activity</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Edward, J.C., William, J.W., Thomas, W.S.
