%X Soil degradation is a global problem that affects many regions and communities, resulting in poor and stress-prone marginal soils. The potentially positive effects of carbon and nutrient content increase through the addition of nutrient-saturated biochar were investigated on poor and saline substrate in experiments with tomato and barley. Biochar treatments were applied to nutrient- and carbon-poor sandy substrates in two greenhouse pot experiments. Biochar mixed with biofertilizers (algae & pig manure) at three total carbon content levels (0.1, 0.3, 0.5 % C-concentration) was applied to test its effects on tomato growth and soil properties during early growth stages. As a follow-up, carbon addition was increased to 2% via a biochar-sheep manure mixture to test its effect on growth parameters and quality of two barley cultivars (Palestinian & German). Results showed that increasing mineral-fertilizer saturated biochar concentration up to 0.5 % total C in saline soil (4 EC) increased tomato total fruit numbers but delayed the ripening process (24% red fruits in untreated pots, 15% in treated pots). In saline environment, biochar-pig manure mixture led to the highest tomato shoot dry weight (41g) compared to 0% biochar treatments (31g). Increased biochar amount (up to 2%) led to increased shoot fresh weight of up to 1.7g in the German barley cultivar after a 1-month growth period, compared to non-treated (0% biochar) pots at 0.9g, respectively. Increasing biochar up to 2% increased the soil water-holding capacity by up to 17% compared to 0% biochar control. In conclusion, nutrient-saturated biochar constitutes a sustainable solution to condition substrates to improve the quality and fertility of the soil by helping to close the nutrient cycle and increasing the water hold capacity, especially in carbon-poor soil substrate. Further up-scaled greenhouse and field experiments are needed to evaluate longer-term effects on yield and soil parameters.
