In the vast regions of eastern Algeria, the calcareous soils are characterised by low fertility. Moreover, these soils frequently lack organic matter and essential nutrients, limiting sustainable yield potential. This study aimed to assess the impact of using locally sourced date palm compost with mineral fertilisers on the improvement of soil fertility in a cereal-based system. A field experiment was arranged in a randomised complete block design (RCBD) with 11 treatments: date palm compost applied at three rates (C1: 30 t ha⁻¹, C2: 50 t ha⁻¹, C3: 70 t ha⁻¹), either alone or combined with monoammonium phosphate (C1M, C2M, C3M: 100 kg ha⁻¹ MAP) or urea (C1U, C2U, C3U: 50 kg ha⁻¹ urea), one treatment with sheep manure at 45 t ha⁻¹, and an untreated control.. The study evaluated the effects of varying rates of date palm compost and mineral fertilisers on soil chemical characteristics at two depths (0–20 cm and 20–40 cm). Results indicated that elevated compost rates, whether applied alone or combined with mineral fertilisers, significantly improved organic matter content, nutrient availability, and soil chemical balance at both depths. Combined treatments C3U (70 t ha⁻¹ compost + 50 kg ha⁻¹ urea) and C3M (70 t ha⁻¹ compost + 100 kg ha⁻¹ MAP) showed the greatest improvements, with C3M identified as the optimal treatment. Integrated date palm compost fertilisation is well-suited to the region's calcareous soils, enhancing nutrient availability, improving soil fertility, and efficiently utilising a locally available resource. These findings suggest that integrating date palm compost with mineral fertilisers is a sustainable approche to improving soil fertility in semi-arid mediterranean systems.
