Abstract

The increasing global population and environmental degradation make agricultural sustainability essential. Soilless farming and microalgae usage are innovative and environmentally friendly approaches in this field. Soilless farming grows plants using water and nutrient solutions, reducing water consumption while enhancing yield and quality. Microalgae serve as biological fertilizers, decreasing the need for chemical fertilizers and minimizing environmental impact. This study evaluates the potential of organic fertilizers in soilless farming by examining the effects of different microalgae concentrations on plant size and leaf development. Today, combating climate change and promoting sustainable agricultural practices are becoming increasingly important. In this context, zero-waste approaches and the use of organic materials as plant nutrients contribute to environmental sustainability and offer an effective strategy in the fight against climate change. The research findings indicate a significant increase in growth (45% and 30%) and leaf development (35% and 30%) in lettuce (Lactuca sativa) and basil (Ocimum basilicum) seedlings. However, the effects were more limited in mint (Mentha spicata) and green tatsoi (Brassica rapa subsp. Narinosa) seedlings. A slight growth increase (22%) was observed in chervil (Anthriscus cerefolium) seedlings. These results highlight the varying responses of different plant species to microalgae applications and emphasize the importance of determining the optimal concentration for plant species to maximize benefits.
