Biostimulants in Sustainable Agriculture and Plant Science

Biostimulants are a diverse classification of substance of microorganism which have positive impacts on plant growth yield and chemical compositions as well as boosting biotic and abiotic stress tolerance. All relevant papers in English language were collected. The major plant biostimulants are protein hydrolysates and other N-containing compounds humic substances seaweed extracts biopolymers microbial biostimulants phosphite and silicon. Produce deeper roots improve stress tolerance accelerate establishment increase cation exchange decrease leaching detoxify heavy metals improve seed germination rates increase stomata opening and plant transpiration increase nutrient uptake stimulate immune systems of plants and their responses increase root development and final yield are just some of the most important of benefits of biostimulants.
