摘要

The repeated use of chemical fertilizers can degrade soil health, posing a threat to long-term food security. This study aims to evaluate whether a single application of steel slag combined with green waste compost can sustainably improve soil fertility, tomato productivity, and fruit quality by supplying slow-release nutrients and enhancing soil organic matter stabilization. Tomato plants were cultivated for four months under uncontrolled field conditions in a semi-arid region. Treatments included control (C), NPK fertilizers (NPK), green waste compost (4.0 t ha⁻¹) (GW), steel slag at two rates, 0.7 t ha⁻¹ (S1) and 1.4 t ha⁻¹ (S2), and their combinations with compost (GW + S1 and GW + S2). The single application of the mixture of compost and steel slag (GW + S1) before the first growing season in 2023 significantly improved soil fertility and crop performance over two consecutive seasons (2023 and 2024), without reapplication in 2024. In both seasons, this treatment led to significant increases in soil organic matter, available phosphorus, and total nitrogen, as well as higher chlorophyll content and soluble sugar concentrations in tomato fruits compared to the control. This treatment also resulted in significantly higher yields, with increases of up to 50% in 2023 and 45% in 2024 compared to the control. The combined use of green waste compost and steel slag at a rate of 0.7 t ha− 1 (GW + S1) offers a sustainable solution for enhancing soil fertility and crop productivity. It supplies long-lasting nutrients that support tomato growth and maintain yield over time.
