We have done a lot of work over the years with the Koanga Institute – a nationally recognised seed-saving, permaculture research and sustainable education organisation dedicated to the protection, conservation and development of New Zealand’s heritage food plants. In 2012, The Koanga Potato Project began and is supported by Environmental Fertilisers. We designed a biological nutrient programme, including solid and liquid fertilisers.

With help from Grant Paton, CEO of Environmental Fertilisers, Kay Baxter, from the Koanga Institute, has worked out the following “recipe” for establishing a vegetable garden:

The recipe we use is as follows per square metre of garden bed, forked into the top 5-10cm before planting seedlings:

1. EF BAS 50 (Paramagnetic Rock Dust) 400 gms (once only)

2. Activated Carbon (Biochar) 400gms (once only)

3. EF Natures Garden Fertiliser 400gms

4. EF Nano-Cal 200gms

After seedlings are planted we sprinkle 100 gms of Natures Garden Fertiliser over each square metre, then we water the seedlings in with a watering can or two containing EF Fish Plus at 100 mls per 10 litres of water. This form of liquid fish is complexed with a carbon source, so does not burn up soil carbon or wash away fast like other forms of liquid fish.

If our crop is a heavy feeder (tomatoes, pumpkins (all cucurbits), corn, brassicas etc) we will apply 100 gms of Natures Garden Fertiliser per sq m each month for the following 3 months.

We will then apply a weekly foliar spray of EF Vegetative Foliar for a month or so then switch to EF Reproductive Foliar until harvest, unless the crop is a heavy feeding leaf crop and then we just continue with the EF Vegetative Foliar.

This level of applying nutrients will mean you are sequestering carbon, growing Nutrient Dense food and you don’t have to keep doing it forever. The higher brix ‘waste’ vegetable material generated can also be added to your compost heap, and you will continue to improve the quality of your food as you build up your soil.

See the letter from Kay Baxter in the testimonial section for further information on what she is doing.
