Abstract This article examined the utilization of digestate as an organic fertilizer to enhance crop yields. In contemporary agriculture, applying digestate as a fertilizer is gaining traction as a viable method for boosting crop productivity. The paper delved into recent studies on the impact of digestate fertilization on crop quality and yield, explaining the production process of digestate, its application techniques, and its effects on plant health. The rise in environmental pollution has underscored the importance of sustainable agricultural practices, increasing the adoption of natural fertilizers. Digestate, a by-product of the methane fermentation process in biogas production, is rich in essential nutrients vital for plant growth and development. This article explored various aspects of digestate fertilization, including its chemical composition and effects on soil and plants. Additionally, it presented scientific findings on the use of digestate as an alternative fertilizer for field crops. The review aimed to provide a thorough understanding of digestate fertilization as well as highlight its potential advantages and challenges in agricultural applications.
