Biostimulants operate through different mechanisms than fertilisers, regardless of the presence of nutrients in the products. They differ also from crop protection products because they act only on the plant’s vigour and do not have any direct actions against pests or disease.
Why use Biostimulants?
Biostimulants foster plant growth and development throughout the crop life cycle from seed germination to plant maturity in a number of demonstrated ways, including but not limited to:
Biostimulants can be of different types:
they can be microbial like fungi or bacteria and non microbial like hydrolized ammino acids, humic acids, plants or algae extracts defined as organic or minerals and chemical compounds defined as non organic.
Biostimulants: where and when?
According to EU Ferilizer Regulation,
A plant biostimulant shall be an EU fertilising product the function of which is to stimulate plant nutrition processes independently of the product’s nutrient content with the sole aim of improving one or more of the following characteristics of the plant or the plant rhizosphere:
(a) nutrient use efficiency,
(b) tolerance to abiotic stress,
(c) quality traits, or
(d) availability of confined nutrients in the soil or rhizosphere.
