Summary
This work investigates the valorization of Ulva prolifera, a macroalgal biomass, through different extraction protocols to produce biostimulants for horticulture. The study measures effects on cherry radish yield, nutrient density, and soil health outcomes, suggesting that extraction method influences biostimulant efficacy. Findings indicate potential for circular bioeconomy applications and sustainable soil management in vegetable production systems.
Regional applicability
Ulva prolifera blooms are prevalent in temperate and warm waters globally; this work's applicability to United Kingdom horticulture would depend on local seaweed availability and biostimulant regulatory approval. The underlying principle—using algal-derived biostimulants to enhance crop nutrition and soil fertility—is transferable to UK vegetable production under similar soil and climate conditions, though cultivar response may vary.
Key measures
Cherry radish growth metrics, nutritional quality (likely mineral and phytochemical content), soil fertility parameters (nutrient availability, microbial activity, or organic matter)
Outcomes reported
The study evaluated how different extraction processes of Ulva prolifera biomass affect cherry radish growth parameters, nutritional composition, and soil fertility indicators when applied as biostimulants.
