Для снижения степени подвижности этого тяжелого металла в почве использовались как химические, так и физико-химические механизмы. В качестве мелиоративных добавок изучали мелиоранты и удобрения (известняковая и фосфоритная мука, суперфосфат, гумат калия, торф, цеолит) в различных дозах. В результате проведённых исследований установлено, что все мелиоративные добавки не только обусловили резкое снижение подвижности хрома на 40-65 %, но и оказали положительное влияние на агрохимические показатели загрязнённой почвы. Характер и параметры этого влияния определялись их химическим составом, дозой внесения и периодом, прошедшим после внесения. Известняковая мука статистически достоверно снизила почвенную кислотность в загрязнённой почве (на 1,21-3,03 ед. рНКСI) и увеличила сумму обменных оснований (в 1,7-6,5 раза). Фосфоритная мука (в 2,1-9,1 раз) и суперфосфат (на 13-43 %) увеличили в почве содержание подвижного фосфора, торф – органического вещества (на 0,28-1,47 абс.%), цеолит – сумму обменных оснований (на 1,4-9,8 ммоль/100 г, или 12-239 %). Положительное действие мелиоративных добавок, особенно их повышенных доз, прослеживалось в течение всех пяти лет наблюдений, что позволяет их рекомендовать в качестве перспективных мелиорантов для восстановления плодородия дерново-подзолистых почв, загрязненных хромом.</p></abstract><trans-abstract xml:lang="en"><p>In the conditions of the Udmurt Republic, field experiments (2017-2021) were carried out on the remediation of  agro-podzolic loamy soil (albeluvisoils) with a high level of chromium contamination (application of 500 mg a.i./kg of soil). Both chemical and physicochemical mechanisms have been used to reduce the degree of mobility of this heavy metal in soil. Ameliorants and fertilizers (limestone and phosphate rock, superphosphate, potassium humate, peat, zeolite) in various doses were studied as ameliorative additives. Various doses of ameliorants and fertilizers were studied as ameliorative additives: limestone and phospharite meal, superphosphate, potassium humate, peat and zeolite. As a result of the research, it was found that all ameliorative additives not only caused a sharp decrease in the mobility of chromium by 40-65 %, but also had a positive effect on the agrochemical parameters of the contaminated soil. The nature and parameters of this influence were determined by their chemical composition, the rate of application, and the period that passed after the application. Limestone flour statistically significantly reduced soil acidity in contaminated soil (by 1.21-3.03 pHKCl units) and increased the total of absorbed bases by 1.7-6.5 times. Phospharite meal (by 2.1-9.1 times) and superphosphate (by 13-43 %) increased the mobile phosphorus content in the soil; peat increased the organic matter content (by 0.28-1.47 abs.%); zeolite increased the total exchangeable bases by 1.4-9.8 mmol/100g or by 12-239 %. The positive effect of these ameliorative additives, especially their increased doses, was traced during all five years of observation, what allows them to be recommended as promising ameliorants for restoring the fertility of soddy-podzolic soils contaminated with chromium.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>тяжелые металлы</kwd><kwd>хром</kwd><kwd>ремедиация</kwd><kwd>мелиоративные добавки</kwd><kwd>агрохимические показатели</kwd></kwd-group><kwd-group xml:lang="en"><kwd>heavy metals</kwd><kwd>chromium</kwd><kwd>remediation</kwd><kwd>ameliorative additives</kwd><kwd>agrochemical indicators</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа выполнена при поддержке Министерства образования и науки Российской Федерации в рамках Государственного задания ФГБУН «Удмуртский федеральный исследовательский центр УрО РАН» (тема № 1021032424706-4-4-1.1).
