Changes in the composition and concentration of soil solutions in seasonal dynamics of irrigated agriculture

Abstract

The investigation focused on examining the seasonal fluctuations in the chemical composition and concentration of soil solutions in irrigated automorphic soils within diverse agricultural zones. It was observed that the composition, concentrations, and relative ratios of various compounds in the soil solutions undergo seasonal variations throughout the growing season, influenced by the process of plant nutrition. The initial stages of the growing season exhibited elevated concentrations of soil solutions, gradually declining towards lower concentrations as the growing season advanced and approached its conclusion. These fluctuations are indicative of dynamic changes in the soil's chemical profile, influenced by the varying nutritional demands of plants at different stages of growth. The observed patterns underscore the intricate interplay between plant development and the temporal dynamics of soil solution constituents. This study enhances our understanding of the seasonal nuances in soil chemistry, emphasizing the importance of considering the temporal dimension in agricultural soil management practices to optimize plant nutrition and overall crop health.
