英文摘要	The residual effect of compost and biochar amendment on soil properties and durum wheat response was evaluated under field conditions in a Mediterranean environment. The treatments compared in a randomized complete block experimental design with three replications were: mineral fertilizer (100 kg N ha(-1)), compost applied at the rate of 25 Mg ha(-1), biochar applied at the rates of 10 and 30 Mg ha(-1), unfertilized control. Wheat was the second crop included in a sorghum-wheat cropping system and did not receive fertilizer supply. A hierarchical statistical analysis was carried out to investigate how different treatments could impact the cropping system performance. The findings highlight the significant influence of soil properties, particularly total N, WEOC, and TOC, on wheat and protein yield. One year after the amendment and fertilizer application, compost and biochar significantly increased soil total organic carbon content. The highest soil water extractable organic carbon was found with the compost application (76.9 mg kg(-1)), whereas the lowest value (50 mg kg(-1)) was with the highest rate of biochar. Soil respiration rates and hydraulic properties were not affected by the investigated treatments. This behavior is probably related to the short experimental duration and to the silty clayey soil texture. Significant correlations were observed between bulk density and water content at pressure heads in the -20 and -100 cm range; this range accounts for the effect of soil macro and mesopores. Multiple linear regression analysis revealed strong predictive power for grain (R-_adj(2) = 0.78; p < 0.001) and protein yield (R-_adj(2) = 0.77; p < 0.001). The highest grain yield (3.36 Mg ha(-1)) was observed with compost, and the lowest (2.18 Mg ha(-1)) with biochar at a rate of 30 Mg ha(-1). These findings lay the basis for understanding how different soil amendment management may impact soil quality and wheat performance, even in consideration of climate change.
