Recently, the central government notified 34 biostimulants to spur manufacturing.

These are substances or microorganisms applied to plants or soil to stimulate natural processes and alsowork by enhancing the plant’s own physiological abilities.
Biostimulants are products that reduce the need for fertilizers and increase plant growth, resistance to water and abiotic stresses.
They improve overall plant health and productivity by targeting processes such as root development, nutrient efficiency, stress tolerance (drought, salinity, extreme temperatures), soil microbial activity.
In addition, biostimulants applied to plants enhance nutrition efficiency, abiotic stress tolerance and/or plant quality traits, regardless of its nutrient contents.
Common types of biostimulants include: Humic and fulvic acids, seaweed extracts, beneficial fungi and bacteria (e.g., mycorrhizae, rhizobacteria).
In India Biostimulants are incorporated under the Fertilizer (Control) Order,1985.
