Biostimulants
Biostimulants
Biostimulants are products that stimulate natural processes in plants and soil to improve growth, nutrient utilization, and stress resistance. Unlike fertilizers, biostimulants provide little or no direct nutrients but enhance the efficiency and functioning of existing fertilization and cultivation systems.
Due to increasing attention to sustainability, soil health, and efficient use of resources, biostimulants play an increasingly important role in modern agriculture and the agro-industry.
What are biostimulants?
Biostimulants are substances or microorganisms that, when applied to plants or soil, activate natural processes. These processes contribute to better nutrient uptake, stronger root development, and higher tolerance to abiotic stress, such as drought, heat, or salinity.
Biostimulants are applied via soil, foliage, or the root environment and complement fertilizers and soil improvers.
Difference between biostimulants and fertilizers
Where fertilizers are aimed at supplying nutrients such as nitrogen, phosphate, and potassium, biostimulants focus on optimizing the processes by which plants absorb and utilize these nutrients.
In practice, biostimulants are therefore often used in combination with organic or sustainable fertilizers to increase the efficiency of fertilization and reduce losses.
Types of biostimulants
There are different categories of biostimulants, each with its own function and application:
- Humic and fulvic acids – improve nutrient availability and soil structure.
- Microbial biostimulants – stimulate soil life and root interaction.
- Plant and algae extracts – support growth, stress resilience, and metabolism.
- Amino acids and peptides – promote rapid uptake and recovery after stress.
Role of biostimulants in the soil
In the soil, biostimulants contribute to a more active and stable soil life. They support the breakdown of organic matter, improve nutrient availability, and contribute to better soil structure.
This makes the soil more resilient and better able to retain water and nutrients, which is essential for sustainable soil management strategies.
Biostimulants and plant resilience
An important advantage of biostimulants is their effect on the stress resistance of plants. By activating natural defense mechanisms, crops can better cope with changing growing conditions.
This leads to more stable growth, better root development, and more efficient photosynthesis, even under less optimal conditions.
Combination with sustainable fertilizers
Biostimulants come into their own when used as part of an integrated fertilization strategy. In combination with sustainable fertilizers, they ensure:
- Higher nutrient efficiency.
- Fewer losses due to leaching.
- Better utilization of organic fertilizers.
- Strengthening soil health.
This directly contributes to lower input costs and better environmental performance.
Biostimulants within circular agriculture
In circular and biobased agricultural systems, biostimulants support the optimal functioning of soil and plants. They help to make better use of residual flows and strengthen natural nutrient and carbon cycles.
For companies in the agricultural chain, biostimulants offer opportunities to make products and processes more sustainable without sacrificing productivity.
Application and strategy
The use of biostimulants requires customization. Factors such as soil type, crop, growth phase, and combination with other inputs determine the optimal timing and correct application.
By strategically integrating biostimulants into the fertilization and cultivation system, a robust approach is created that contributes to future-proof agriculture.
Summary
Biostimulants are a powerful tool within modern agricultural systems. They improve fertilization efficiency, strengthen soil health, and increase crop resilience. In combination with sustainable fertilizers, biostimulants are an essential part of circular and efficient agriculture.
