International audience ; This study investigated the impact of organic amendments (compost, biochar, and theircombinations) obtained from date palm residues on nutrient leaching, soil fertility, and barley (Hordeum vulgare L.) uptake in a controlled environment in an Ecolab climatic chamber. Six treatments were evaluated: Urea (U), compost (C), biochar (B), biochar-compost (BCC), biochar-urea (BCU), and a non-amended soil as control (S). Compost and BCC amendments significantly increased initial Olsen-P, exchangeable K, and Na in the upper soil layer (0-17.5 cm) compared to the non-amended soil. After barley cultivation (125 days), these amendments maintained higher levels of phosphorus (P) and potassium (K) compared to the non-amended soil. Available Fe and Zn were also significantly higher in compost-amended soils. Cumulative leaching of most elements (phosphate, potassium, sulfate, sodium, chloride) increased initially and then stabilized. Compost and BCC treatments generally showed higher leaching of K, Na, and Cl compared to the non-amended soil. However, total sulfur, Ca Mg leaching did not differ significantly among treatments. The results from this study demonstrate that the agronomic benefits of date palm-derived biochar in the short term under arid conditions are limited for sandy soil. |
