Abstract: Abstract Maize grain yield and response to N (0, 50, and 100 kg ha −1 ) and P fertilization (0, 15, and 30 kg ha −1 ) were determined for fields differing in history of organic inputs of four farmers in the Sudan savanna zone of northern Togo over a period of 3 years. Each farmer selected a field that had benefited from long-term organic inputs close to his family homestead (‘infield’) and another field receiving considerably less or no organic inputs (‘outfield’). Soil organic C content was 13.4 g kg −1 for infields and 6.3 g kg ...
