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
See page 1 for more details
|SEER Rock dust||9.5||9.0||12||2826||2.0||4.0|
* Readings taken early in season. The rest were taken during the first week in October.
Overall the remineralised beds (sea water and rock dust) did better than the control (no treatment) and the bed where plants were regularly sprayed with seaweed extract. The bed treated with rock dust from The SEER Centre was slightly better that the one where desalianted sea water was used.
The 4 onions patches produced over 10kg from 36 onions in the equivalent of 1 square metre. That is a remarkable result.
I intend to continue the trial next year to see if there is any cumulative effects.
