Revolutionising farming with biostimulant products

By Murimi Gitari

[rt_dropcap_style dropcap_letter=”A” dropcap_content=”ALL living organisms have the ability to improve themselves through natural means in order to adapt to changing environmental conditions. However, it takes some time before any detectable improvement is obtained. In crop farming, biostimulant products present an opportunity to improve plants more efficiently and effectively.”]

What is a biostimulant?

A plant biostimulant is any substance or microorganism which when applied to plants or seeds stimulates natural processes to enhance nutrient uptake, nutrient use efficiency, tolerance to abiotic stress, or crop quality and yield. By incorporating biostimulants into your agricultural practices, you can stimulate root development, increase crop resilience, improve soil fertility, boost seed germination, promote efficient water use, optimise nutrient availability, and manage plant stress. Biostimulants are not classified as fertilisers.

What are biostimulant products?

Plant biostimulants are derived from naturally occurring, diverse communities of microorganisms and the biochemical byproducts they produce (e.g., organic acids, proteins, enzymes). Biostimulant products typically include ingredients from one or more of the following general categories:

  • Humic and fulvic acids occur naturally in soils as a result of the breakdown of organic matter.
  • Protein hydrolysates like small peptides and amino acids, the building blocks of all proteins.
  • Seaweed and plant extracts that contain minor nutrients and plant hormones such as cytokinin. Plant extracts may contain substances that can stimulate plant metabolism or natural defence systems.
  • Chitosan and other biopolymers. Biopolymers are specific molecules derived from plant or animal sources; for instance, chitosan is derived from the shells of crustaceans.
  • Inorganic compounds. These are mineral-based molecules such as phosphites, and minor elements such as silicon.
  • Beneficial microbes. The action of these products is based on the activity of live fungi and/or bacteria.

Why go biostimulants?

Biostimulants offer a range of advantages for sustainable and high-yield crop production. With the soaring of fertiliser prices across the globe pressure is mounting on the farming communities to cut down on the amounts spent on synthetic inputs. Coupled with the tightened rules surrounding the use of synthetic crop protection products biostimulants become a fair prospect. With the world embracing regenerative agriculture practices, biostimulants sit perfectly in this space.
