Nitrogen leaching and indirect nitrous oxide emissions from fertilized croplands in Zimbabwe
Agricultural efforts to end hunger in Africa are hampered by low fertilizer-use-efficiency exposing applied nutrients to losses. This constitutes economic losses and environmental concerns related to leaching and greenhouse gas emissions. The effects of NH 4 NO 3 (0, 60 and 120 kg N ha −1 ) on N upt...
