Abstract
Microalgae based biofertilizers are emerging as a sustainable alternative to synthetic fertilizers, offering the potential to enhance plant growth while improving soil health. This study investigates the effectiveness of microalgae applications on the growth performance of garden peas (Pisum sativum), and associated changes in soil fertility. A microalgal culture was applied as a soil amendment under controlled garden conditions, and plant growth parameters—including germination rate, shoot and root length, and weekly plant growth—were monitored throughout the growing cycle. Soil samples were analyzed for nutrient content, organic matter, and microbial activity before and after treatment. Results demonstrated that microalgae application significantly improved plant vigor and yield compared to untreated controls, with notable increases in nitrogen availability and soil microbial activity. These findings highlight the potential of microalgae as an eco-friendly biofertilizer capable of supporting sustainable home garden and agricultural practices. Further research is recommended to optimize application rates and evaluate long term soil impacts.
