Green algae liquid fertilizer—usually labeled as liquid seaweed fertilizer—is a nutrient-rich, organic product widely used to promote plant growth and improve soil health. Most commercial seaweed fertilizers are made from brown or green marine algae, but some formulations use green algae (Chlorophyta) specifically[1][2].
These fertilizers contain a wide spectrum of nutrients, including macronutrients (like nitrogen and potassium) and a broad profile of micronutrients (iron, copper, zinc, manganese, boron)[3][2]. In addition to minerals, they are valued for naturally occurring plant hormones (such as cytokinins, gibberellins, and auxins) that stimulate root growth and increase resistance to stress and disease[4][2].
Key benefits:
- Enhances root development and plant vigor due to high levels of growth hormones and bioactive compounds[4][2][5].
- Improves soil structure and boosts soil microbial life with organic matter and polysaccharides[5][4].
- Increases nutrient absorption and crop yields when used as a foliar spray or soil drench[5][2].
- Suitable for both conventional and organic agriculture[2][5].
Application is typically by diluting a set amount (such as 5ml per liter of water) and distributing it via soil watering or foliar spray; directions may vary by product[2][4]. Green algae can also be added directly to compost or soil, where it decomposes and releases nutrients gradually[6].
There is some debate about direct use of raw green algae from ponds due to the risk of introducing toxins or pathogens, but when processed properly–as in commercial products or well-composted homemade brews—it is generally beneficial[6][7].
Green algae-based fertilizers contribute to sustainability by reducing reliance on synthetic chemicals and supporting biodiversity in soil ecosystems[5].
Caveats:
- Effectiveness and nutrient concentration may vary by algae species and product[1].
- Always use in moderation and according to soil and crop needs—excess can sometimes disrupt soil balance[5][2].
If you are considering making your own liquid fertilizer from green algae, it is recommended to compost it first or steep it in water for several weeks to create a "fermented" tea before applying[7][6]. Commercial options typically provide a standardized, safe, and effective formula[2][4].
