Biochar and nitrogen effects on nitrate leaching, physiological performance, and rhizome quality of turmeric (Curcuma longa L.) in sandy soil
Nitrogen fertilization in sandy soils often results reducing nitrogen use efficiency and posing environmental risks. Biochar has been proposed as a soil amendment to improve nutrient retention and crop quality. However, the combined effect of biochar and graded nitrogen rates on the physiology and rhizome quality...
