What is a biostimulant in agriculture?

Biostimulants are substances and microorganisms used in agriculture to improve plant growth, health, and productivity.

Biostimulants work by enhancing plant nutrient uptake, stress tolerance, and root growth, among other benefits. Biostimulants differ from fertilizers in that they do not directly provide nutrients to plants but rather stimulate natural processes within the plant to promote growth and health.
