Abstract Besides their potential for carbon sequestration, compost and biochar application in agriculture may constitute an alternative to mineral fertilizers by improving soil fertility productivity carbon‐poor soils. This study focused on the impact of produced from date palm residues nitrogen (N) leaching plant uptake a sandy cultivated with barley under arid climatic conditions. In addition unamended control (S), treatments (BC), urea (U), + (BCU), (C) (BCC) were tested. We followed parameters, N losses, growth. Results showed significant increase yields compared (+66%) treatment amended (BC) (S). Biochar alone or co‐applied nutrient source seems reduce shoot biomass grain at short term. Leachate recovery extractable inorganic end cultivation indicated that did not provide excess maturation stage. Compost soils led highest losses through thus environmental risk vertical transfer. However, had positive effects status yields. No synergistic effect was observed between compost. conclusion, this paper highlights improved coarse‐textured soil, but very short‐term concerning available N.
