Effects of different types of acidic nitrogen-enriched biochar on spinach growth, nitrogen use efficiency, and chemical properties of calcareous sandy soil

Abstract Background Enriching biochar with nitrogen and using it as a slow-release nitrogen fertilizer is a promising strategy to avoid excessive use of chemical nitrogen fertilizers. Therefore, this study investigated the effect of different types of nitrogen-enriched biochar on the soil’s chemical...
