Microbial Biostimulants Market: Overview

Microbial biostimulants are biologically derived agricultural products that consist of useful microorganisms, such as bacteria, fungi, and others, to enhance plant growth and development, as well as nutrient acquisition, but not to function as fertilizers or pesticides. The microorganisms reside in the rhizosphere or inner layers of plants; create favorable soil conditions; facilitate root development; enhance nutrient absorption through nitrogen fixation and phosphate solubilization; and assist plants in building resistance to environmental stresses such as drought and salinity. Microbial biostimulants have widespread applications in cereals, fruits, vegetables, oilseeds, pulses, turf, and ornamentals to increase the productivity and sustainability of agricultural produce. The need for sustainable and regenerative agriculture is a key driver of the growing use of microbial biostimulants.
