Relationship between biostimulants and fertilizers

The relationship between biostimulants and fertilizers ‌ is mainly reflected in their complementary and synergistic effects in agricultural production. Biostimulants are a new type of fertilizer. Although they do not directly provide nutrients, they can stimulate the physiological and biochemical processes of plants, enhance the absorption and utilization of nutrients by plants, and improve the stress resistance and crop quality of plants. ‌
Definition and classification of biostimulants ‌

Biostimulants refer to a class of preparations or microbial products applied to plants or root zones that can stimulate plants to increase nutrient absorption, improve nutrient efficiency, improve resistance or crop quality. They do not directly provide nutrients, but work by stimulating the physiological and biochemical processes of plants themselves ‌



Biostimulants can be divided into two categories: microbial sources and non-microbial sources.
The former includes agricultural antibiotics, microbial pesticides and microbial fertilizers, while the latter includes humic acid, amino acids, seaweed extracts, etc. ‌
Specific differences between biostimulants and fertilizers ‌
The main difference between biostimulants and ordinary fertilizers is that their mechanisms of action are different. Ordinary fertilizers mainly promote growth by providing chemical elements required by plants, while biostimulants stimulate the physiological and biochemical processes of plants themselves to improve nutrient absorption and utilization efficiency and enhance plant resistance. In addition, biostimulants also include certain microorganisms and biochemical materials, which can promote plant growth and development when applied to plants or soil.

Application scenarios and effects of biostimulants
The application scenarios of biostimulants include application during critical periods of plant growth or under adverse conditions to enhance plant resistance. For example, under adverse co
