Yield and soil fertility trends in a 20-year rice-rice-wheat experiment in Nepal
The rice (Oryza sativaL.)–wheat (Triticum aestivumL.) cropping system occupies about 13.5 million ha in South Asia and is important for the region's food security. We examined the long‐term yield trends, changes in soil nutrient fractions (both total and available), and nutrient balances in a 20‐yr...
