Bioactive carbon improves nitrogen fertiliser efficiency and ecological sustainability

Abstract Agriculture’s most pressing challenge is raising global food production while minimising environmental degradation. Nutrient deficiencies, principally nitrogen (N), limit production requiring future increases in fertiliser use and risk to proximal non-agricultural ecosystems. We investigate...
