TYPE OF BIOSTIMULANTS

FOCUS ON: BENEFICIAL MICRO-ORGANISMS

Soil’s health is essential for good root and plant growth. Micro-organisms are principal actors of soil’s life and so they play a prominent role in plant development. Many micro-organisms such as bacteria, fungi (especially mycorrhizal fungi) are acting on the plant also as biostimulants.

FACTS AND FIGURES:  Soil is alive!! In 1 g of soil we can find until 1 billion of bacteria and 1 million of fungi and protozoa.


Types of biostimulants - fungi - bacteria - Mycorrhyzal fungi

FUNGI

  • Degradation of organic matter
  • Solubilisation of nutritional elements
  • Root Biostimulation
  • Formation of aggregates
  • Root colonization
  • Competition with other organisms

BACTERIA

  • They participate in the Nitrogen cycle (Fixing, nitrification,…)
  • Root Biostimulation
  • Solubilisation of soil nutrients
  • Promotion of soil aggregation
  • Promotion of plant growth (PGPR)

MYCORRHIZAL FUNGI

Mycorrhizae is the name of the plant-fungus symbiosis. Without the root, the fungus dies.

  • Increase of root absorption area (from 100 to 1000 times)
  • Carrier of nutritional elements and water
  • Increase water retention capacity
  • Improvement of tolerance to abiotic stress
  • Biostimulation of roots
  • Formation of aggregates (better soil structure)

HOW TO INCREASE MICRO-ORGANISMS DEVELOPMENT?

How to increase micro-organisms development

Many factors can influence micro-organisms development. Some biostimulant products are able to stimulate the growth of beneficial microbials in the rhizosphere and surrounding soil, improving soil biological fertility.
