Notes: The dependent variable in all models is maize yield measured in
kg ha-1. N = nitrogen; POXC = active carbon; CV =
coefficient of variation. Rainfall measured in 10-day periods during the
growing season for the survey year. Standard errors are cluster robust
at the household level. Significance denoted by * (p<0.1), **
(p<0.05) and *** (p<0.01). Full results shown in
appendix (table A1).
