Use for

Vidi Funda is a natural and organic soil improver based on raw materials. The product contains a unique combination of amino-acids which support the development of a diverse soil population of beneficial microbes, especially fungi. By improving the overall soil health, as well as supplying plant-based organic nutrients, research and commercial applications have shown an increase in available nitrogen from mineralization. Following mineralization, the plant can easily absorb the nutrients from the Vidi Funda, which reduces leaching.

When to use Vidi Funda?

  • Improve the availability of nutrients through mineralization 
  • Increase soil fungi-bacteria and C:N ratios  
  • Establish and maintain a raised biomass weight of organisms within the substrate 
  • Re-build the soil life and vitality after destructive applications 
  • Promoting plant growth through rhizosphere environment, soil buffering capacity and the ability to withstand stress

How it works

How it works

How does Vidi Funda work?

The pellets are scattered, and ideally worked into the growing medium. Over time, with the interaction of temperature, moisture, air and the existing microbial population, the pellets will slowly break-down and release the amino-acids into the surrounding soil. It is this gradual decomposition that supports and develops the soil microbial population and the increased bio-availability of nutrients.

Many alternative soil amendments will either release nutrients rapidly or lock them up. This can lead to flushing and varying results. Vidi Funda is applied to restore and maintain the soil’s natural balance, so that it can support efficient and resilient growth.
