1 - 2008 trial - 29 Apr
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.
This bed had basalt rock dust added which was raked into the surface of the soil
