Features:

1. Hormonal effects: Bio stimulants like seaweed extracts contain plant hormones like auxins, cytokines and gibberellins that regulate growth and development.

2. Stress tolerance: Many bio stimulants boost abiotic stress tolerance against drought, salinity, heat, and cold stress by inducing antioxidant production, osmotic adjustments and other protective compounds.

3. Root growth promotion: Bio stimulants enhance root growth and architecture, improving access to water and nutrients. Microbial bio stimulants also facilitate nutrient mobilization in the rhizosphere.

4. Cell metabolism modulation: Bio stimulants improve photosynthetic efficiency, nitrogen assimilation, enzyme activity, and other metabolic processes resulting in increased vigor.

5. Biocontrol: Microbial bio stimulants can induce systemic resistance against diseases and pests by priming plant immune responses.

Benefits:

Increased Yields

One of the most notable effects of bio stimulants is their ability to increase crop yields. By enhancing plant growth, metabolism, and development, bio stimulants can improve productivity and lead to higher yields per acre. Studies have shown yield increases ranging from 5-30% depending on the crop and bio stimulant used. The yield boosts are especially significant under suboptimal or stressful conditions.

Enhanced Quality

In addition to increasing yields, bio stimulants can also improve the quality and nutritional value of produce. They help plants properly ripen, leading to higher brix levels, better coloration, extended shelf-life, and enhanced sensory properties. Bio stimulants promote the synthesis of secondary metabolites which boost nutritional content.

Improved Stress Tolerance

Plants treated with bio stimulants have greater tolerance to abiotic stresses such as drought, extreme temperatures, salinity, and heavy metals. Bio stimulants mitigate the impacts of stress at physiological and cellular levels. This allows plants to maintain growth and productivity even under suboptimal conditions.
