Compost and Vermicast is Proven to work

Over the past five years, there has been a
dramatic increase in the amount of international
scientific research investigating the benefits of
vermicast as a soil conditioner and fertiliser.
The results have been favourable – vermicast
has been shown to increase both yield and
quality in a range of crops, both overseas and in
New Zealand.
Scientific studies have documented that vermicast
produces growth responses in plants that are far
greater than would be expected from supplying
nutrients alone, as in most traditional fertilisers.
Humic acids stimulate plant root growth and
increase the permeability of roots to nutrients.
The natural plant growth hormones found in
vermicast have been shown to have dramatic
effects upon plant growth.
