Organic inputs as a substitution for, or addition to, chemical fertilizers can potentially mitigate N losses. However, it is not well known how their effects on N leaching and runoff depend on application approaches. We conducted a global meta-analysis of 129 studies to compare the effects of organic inputs on N export via leaching and runoff. We compared three application approaches chemical fertilizer N substituted by organic fertilizer with 1) equal amounts of total N or, 2) equal amounts of mineral N and 3) additional organic
