1Productivity
If conventional agricultural methods are used to promote seed emergence and plant growth, then basic crop production is maintained, but yield optimization and soil health improvement are insufficient, especially under stress conditions
Solution Approach 1:
The patent applies parameter changes by modifying the chemical composition parameters of the treatment solution through the inclusion of specific microalgae species (Chlorella vulgaris, Scenedesmus acutus, and/or Nannochloropsis oculata) at controlled concentrations (0.1-10% v/v), along with nitrogen sources (0.1-5.0 g/L) and phosphorus sources (0.1-5.0 g/L). These parameter modifications enable the treatment to enhance seed emergence, plant growth, and yield while improving reliability under stress conditions compared to conventional methods
Solution Approach 2:
The patent employs composite materials by creating a multi-component treatment formulation that combines microalgae biomass or extracts with specific nutrients (nitrogen and phosphorus sources) and optionally other beneficial microorganisms. This composite approach synergistically improves crop productivity and stress tolerance beyond what single-component conventional treatments can achieve
2Productivity
If high concentrations of nutrients are applied to promote rapid plant growth and yield, then productivity increases, but environmental impact and resource efficiency deteriorate
Solution Approach 1:
The patent applies self-service by utilizing microalgae that naturally produce and release beneficial compounds, growth promoters, and nutrients during their growth cycle. The microalgae serve themselves by converting ambient nutrients and CO2 into bioactive substances that then benefit the target plants, reducing the need for external chemical inputs and minimizing environmental impact while maintaining high productivity
Solution Approach 2:
The patent changes the concentration parameters of nutrient application by using low concentrations of microalgae (0.1-10% v/v) and nutrients (0.1-5.0 g/L each), which are significantly lower than conventional fertilizer applications. This parameter reduction achieves comparable or superior yield improvements while substantially reducing environmental harm and resource consumption
