Summary
This review examines how microalgae function as biofertilizers by analysing the mechanisms through which they supply nutrients to crops, alongside the industrial, technical and economic barriers currently limiting their wider adoption in agriculture. The authors synthesise current understanding of nutrient bioavailability and suggest pathways to overcome implementation challenges, though the specific evidence base and quantitative findings remain inferential from the title and journal focus.
Regional applicability
Findings on microalgae biofertilizer mechanisms and industrial challenges would be applicable to United Kingdom agriculture seeking sustainable nutrient inputs, particularly for intensive or organic systems, though transferability depends on local production capacity, climate compatibility and regulatory frameworks for novel biofertilizers.
Key measures
Nutrient supply mechanisms from microalgae; industrial scalability challenges; sustainability metrics for biofertilizer production and application
Outcomes reported
The study analysed nutrient supply mechanisms of microalgae-based biofertilizers and identified industrial and technical challenges limiting their uptake in sustainable agriculture. It likely synthesised evidence on nutrient bioavailability, application efficacy and barriers to commercialisation.
