3 Reasons to Use Fermented Kenaf as a Soil Additive

Recently I came across kenaf, and wanted to explore the possibilities of this amazing plant.

I became very interested in the power of microbes to decompose organic material and extract the nutrients for plants, and became especially interested in increasing the health of my garden! When I saw the power of the bacteria in several applications during my career in the microbial world I began applying them to great effect on my indoor plants and in my garden.


Kenaf is a type of hemp which has been grown throughout the world for many years and is being grown in the United States in increasing volume now that hemp has been legalized. The cell structure of kenaf is like a tiny honeycomb, and can absorb up to 60% of it’s volume in liquid. This is why it has been used in the drilling industry to line the oil drills and soak up spillage.

The ground core of the kenaf plant when fermented with beneficial bacteria (KENKASHI) is ideal as a soil additive for a number of reasons.

  1. It is a good source of microbes. We commissioned a series of tests at a local university and the results confirmed that microbial and fungal activity was greatly increased by the addition of KENKASHI.
  2. The KENKASHI increased the water retention in sandy soil and loosened the dense quality of clay, heavy soils, thereby increasing the drainage of heavy soils.
  3. By the addition of a blend of myccorhizal fungi the KENKASHI is fully loaded and ready to go to boost the availability of nutrients to plants.

Please note: KENKASHI is not a fertilizer in itself, and needs to be applied in conjunction with some form of plant food.
