Abstract
<jats:p>Alluvial deposits that accumulate on floodplain lands contain a large number of nutrients that help optimize the agrochemical properties of soils. These sediments, or sediments, have an impact on the plant community of floodplain lands, improving their qualitative composition. Involving them in cultural agriculture while carrying out appropriate crop engineering and land reclamation work makes it possible to obtain guaranteed crop yields. The results of three years of research on the agroecological condition of floodplain seasonally frozen soils are presented. Agrochemical properties were analyzed with the determination of total humus, nutrients: nitrogen, phosphorus and potassium. The composition of the exchange cations and the reaction of the soil medium are determined. Despite the high potential fertility, the productivity of these lands is low, which is associated with insufficient soil moisture during dry periods. A flyby of the land using an unmanned aerial vehicle was carried out to establish degradation processes. Currently, studies are continuing to establish the water regime of soils in years of varying rainfall.</jats:p>
