About BIOSTIMULANT GRANULAR
Definition and Purpose
Biostimulants are products containing substances or microorganisms applied to seeds, plants, or the rhizosphere to stimulate natural processes in plants, enhancing nutrient uptake, nutrient-use efficiency, tolerance to abiotic stress, and crop quality . Unlike fertilizers, they do not directly supply nutrients but improve the efficiency of absorption from the soil . Granular formulations are applied to soil, releasing bioactive compounds over time and supporting root and microbial activity . Types and Composition
Granular biostimulants can be broadly categorized into microbial and non-microbial types:
1. Microbial Granular Biostimulants:
-
Contain beneficial microorganisms such as plant-growth-promoting rhizobacteria (PGPR), arbuscular mycorrhizal fungi (AMF), and other bacteria/fungi that enhance nutrient availability, root growth, and disease resistance .
-
Standardized by colony-forming units (cfu/g) or spore counts. Examples include Bacillus, Pseudomonas, Azospirillum, Rhizobium, Glomus, and Trichoderma spp.
2. Non-Microbial Granular Biostimulants:
