Biostimulants activate the natural processes of the plant, strengthening its growth and development. These compounds improve root growth, increase nutrient uptake, and enhance the plant’s tolerance to environmental stresses, so the plant can perform optimally even under challenging conditions.
How do biostimulants work?
There are various types of biostimulants, and each works in a different way:
- Some contain plant hormones that regulate growth and development.
- Some include amino acids that improve nutrient uptake and stress tolerance.
- Others contain beneficial microorganisms that help the plant cope with diseases and pests.
Main mechanisms of action of biostimulants
In general, their effects can be divided into three main categories:
- Improving nutrient uptake and utilization
Biostimulants can increase the uptake and use of essential nutrients. For example:
- They improve root growth and function
- Increase nutrient availability in the soil
- Enhance nutrient absorption and utilization efficiency in the plant
- Increasing stress tolerance
Biostimulants help plants better cope with environmental stresses such as drought, extreme temperatures, and salinity. They do this by stimulating the production of stress-related proteins and increasing the plant’s antioxidant capacity.
- Promoting plant growth
Biostimulants can enhance plant growth by increasing cell division and elongation, boosting chlorophyll production, and improving overall plant vigor. They also increase the plant’s resistance to pests and diseases.
It is important to note that the mechanisms of action of biostimulants may vary depending on the type of biostimulant, plant species, and growing conditions. However, the main goal of using biostimulants is to enhance plant growth and development in a sustainable and environmentally friendly way.
Benefits of using biostimulants
One of the most important benefits is that they are a natural solution. They can increase crop yield, improve plant health and product quality, without introducing harmful chemicals into the environment, ultimately boosting farmers’ profitability.
