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).
