Abstract

This study evaluated the effects of a Chlorella-based liquid bio-fertilizer (LBF) on the growth, forage quality, antioxidant capacity, and soil chemical properties of forage corn. Regarding plant growth, the shoot length of LBF-treated corn increased from 107.47 cm to 126.98 cm at 23 days after sowing, representing an 18.2% increase. Similar improvements were observed at 40 days and 66 days. The crude fiber content significantly decreased from 23.23% in the control group to 20.58% in the LBF-treated group, indicating improved digestibility. Antioxidant activity was also significantly enhanced. In LBF-treated plants, total polyphenol content increased from 3.42 mg GAE/mL to 4.15 mg GAE/mL, and total flavonoid content increased from 7.82 mg QE/mL to 9.22 mg QE/mL. DPPH radical scavenging activity showed a highly significant increase, and ABTS activity was also significantly improved. Soil chemical properties were notably improved following LBF application. Soil pH increased from 5.70 to 6.25, organic matter content rose from 4.30% to 5.50%, and total nitrogen content increased from 2,230.41 mg/kg to 2,656.88 mg/kg. Additionally, available phosphorus increased from 994.68 mg/kg to 1,234.19 mg/kg, and the cation exchange capacity (CEC) improved from 16.07 cmol+/kg to 17.23 cmol+/kg. Overall, these findings suggest that LBF application can promote early-stage growth, improve forage quality by reducing fiber content, enhance antioxidant capacity, and improve soil fertility, thereby supporting more sustainable crop production.
