Context This study examines the legacy phosphorus (P) supply capacity of crops under a conservation agriculture (CA)-based maize (Zea mays L.)–mustard (Brassica juncea L.) system, particularly in Inceptisol soils of the hot semi-arid, sub-tropical north-western Indo-Gangetic Plains agro-ecoregion of India. Standard nutrient management protocols for CA remain a challenge due to the limited data on P dynamics in such systems. Aims To evaluate the effects of different tillage and residue management
