Abstract

The assessment of soil fertility and its ability to support high agricultural yields is primarily determined by the availability of essential nutrients in forms accessible to plants. Therefore, agrochemical analysis of sandy soils, which provides insights into the dynamics of mobile nutrient forms such as nitrogen, phosphorus, potassium, and organic matter, is crucial for informed fertilizer management. In this context, a systematic approach to determine the optimal fertilizer rates and their application methods is fundamental to achieving sustainable crop production. The enrichment of sandy and sandy-loamy soils through targeted agrotechnological practices and innovative technologies plays a pivotal role in restoring and enhancing soil fertility. Additionally, effective strategies to protect against sand erosion, optimise irrigation practices, and apply fertilisers in appropriate quantities and proportions are crucial for increasing yields, particularly in cotton cultivation. This research addresses these challenges, emphasizing the importance of a balanced approach to fertilizer use and the development of sustainable agricultural practices for cotton production under irrigated conditions.
