A field experiment was carried out at the Experimental Farm of Soils and Water Department, Faculty of Agriculture, Al-Azhar University, Cairo, Egypt, to study the effect of two organic types of amendments (biochar: 2.5 and 5 ton/fed, compost: 5 and 10 ton/fed, and their combinations) on soil characteristics and the productivity of faba bean and wheat crops. Results revealed that the sole applications of organic amendments, either biochar (T1: 2.5 and T2: 5 ton/fed) or compost (T3: 5 and T4: 10 ton/fed), improve water and nutrient retention as well as enhance plant growth and yield of faba bean and wheat as compared to the control treatment (T0). Furthermore, the mixed applications of biochar and compost, especially with the increase in application rates (T5:T8), further improved the soil's physical and chemical properties than the single ones at T1:T4. Results showed that the relative increases in available water values over control treatment under different treatments of biochar and compost (T1, T2, T3, T4, T5, T6, T7, and T8) reached 5.16, 10, 7.26, 12.74, 15.32, 26.61, 31.77 and 36.61% for soil planting with faba bean while, the corresponding values for soil planting with wheat were 5.07, 10.29, 7.03, 12.58, 14.54, 18.46, 22.88 and 28.76%, respectively. Also, the highest mix of two organic amendments at 5-ton biochar and 10-ton compost per fed recorded the highest significant values of macro and micronutrient availability in soil and their content in straw and grains of faba bean and wheat plants.
