Abstract

•Application of P significantly increased soil total-P, Olsen-P and CaCl2-P over years.•P efficiency was from 20 to 54% or from 13 to 33% in double or single cropping system.•Olsen-P was about 14 or 16 mg kg−1 for optimal crop yield in respective systems.•Olsen-P moved down to a depth of 300 cm in the manure applied treatments.
