Plant biostimulant formulation from microalgae biomass using wastewater
Innovative plant biostimulant derived from microalgae biomass cultivated in pig wastewater to enhance growth of tomato, potato, and corn. Utilizes phytohormone-rich microalgae, offering a sustainable, cost-effective solution for agriculture.
Overview
This innovative solution involves the formulation of a plant biostimulant derived from microalgae biomass cultivated using pig wastewater. The approach leverages the nutrient-rich nature of wastewater to grow microalgae, which inherently contain growth-promoting phytohormones such as auxins, cytokinins, and gibberellins. This biostimulant aims to enhance the physiological and morphological behavior of crops like tomatoes, potatoes, and corn by providing a sustainable and cost-effective alternative to conventional fertilizers.
Technical specifications
Key features:
- Utilizes pig wastewater as a nutrient source, reducing waste and cost.
- Grows microalgae species such as Chlorella vulgaris and Spirulina maxima, which are rich in plant growth hormones.
- The biostimulant is formulated to enhance crop growth and health, tested initially in greenhouse settings and subsequently in field conditions.
Biochemical Composition:
- Contains phytohormones: auxins, cytokinins, gibberellins, and abscisic acid.
- Potential to decrease environmental contaminants by recycling wastewater.
Technology readiness level
Currently at TRL 3, this technology has moved beyond the initial concept stage with experimental proof of concept achieved. Future validation will involve optimization of biomass production parameters and effectiveness testing in greenhouse and field conditions.
