Long-term effects of urea and green manure on rice yields and nitrogen balance
Data from a 14‐yr double‐crop rice (Oryza sativa L.) experiment allowed comparison of the long‐term effects of N fertilizer from different sources (urea and in situ grown azolla [Azolla microphylla Kaulf.] and sesbania [Sesbania rostrata Bremek. and Oberm.]) on N balances, soil N pools (both total a...
