This will be the report of a simple double blind test to determinate the influence of the purity of dross on the purity of the final crops, cabbage in this case.
This was inspired by the fact that none of the persons i asked in Boston seemed to know how far(if at all) dross purity influences crop purity.
The Test itself consists of 3 newly tilled fields planted in the following fashion:
All Fields are planted with 1.00 Humus, 10 wood choppings and 1.00 cabbage seeds
Field 1:
151% speed
74% plenty
24* 10% pure Dross with:
-17,60 Salt
-19,08 Mercury
-49,10 Sulphur
-14,24 Lead
Field 2:
151% speed
50% plenty
24* 0% dross with:
-22,68 Salt
-29,39 Mercury
-27,87 Sulphur
-20,05 Lead
Field 3:
106% plenty
No Fertilizer besides the wood choppings
The results won't be accurate since I used wood choppings and I only use 3 fields but a trend should be visible.
Results will follow in about 3 days.
EDIT: Results are in.
Field 1:
25,90 ; 25,28; 27,04; 21,78
Field 2:
22,39;21,34;27,59;28,68
Field 3:
27,25;28,20;20,52;24,03
So looks like the wood chippings + the rng average the purity increase of the dross.
Will repeat the test without the wood chips and more fields to average the rng.
