Abstract
The purpose of the research is to assess the qualitative composition of former drained reclaimed lands in the Irkutsk district of the Irkutsk region and provide recommendations for the involvement of these lands in agricultural use. In order to bring formerly drained lands into agricultural use, but currently not in use, it is necessary to assess the qualitative condition of the soils (physical and chemical properties of the soils, the content of organic matter and basic elements in the soil, salt composition, etc.) and the condition of the canals. The article provides an analysis of the factual material of former (now abandoned) reclaimed lands in the region favorable for agriculture – Irkutsk, which is located in the south of the Irkutsk region. The material for the study was soil samples taken from formerly drained lands. The qualitative condition of reclaimed lands was assessed by assessing the knowledge of organic matter and mineral composition of soils, acidity, and salinity. Analytical studies were carried out in accordance with GOST. The results obtained allowed us to conclude that the currently abandoned lands are highly productive – meadow chernozem with a high content of organic substances, enriched in sodium, phosphorus, potassium, low content of bicarbonates. The low content of sulfates and chlorides indicates that the process of soil salinization is not observed, with the exception of 3 cases, which are discussed below. With minor reclamation work, these lands can be involved in agricultural production.
