2008 trial 1

This is a trial of different ways to attempt to increase the levels of minerals in food. Previously I have used basalt rock dust as a soil amendment but have never done comparative trials of different remineralisation methods.

For this trial there are 4, 1m (approx) square beds as follows:

1  – Soil
2  – Soil + seaweed foliar spray
3  – Soil + sea minerals
4  – Soil + rock dust

Each bed will grow 4 separate crops, planted at the same time and treated in exactly the same way. The crops are: onions, carrots, lettuce/cabbage and dwarf French beans.

At harvest each crop will be sampled for BRIX levels and records kept. I hope to be able to repeat the trial over next 4-5 years.

A good explanation of BRIX and nutrient density can be found in The-Quest-for-Nutrient-Density by Jon C. Frank.

The beds were completed and 9 onions planted in the same square of each bed today, 29 April 2008.

A bucket of garden compost was added to each bed and lightly forked in
This bed had basalt rock dust added which was raked into the surface of the soil
