Agriculture of Tomorrow Chapter IV Further Experiments With Wheat This chapter shows the results of 0 to 60th potencies of the salt fertiliser materials in common usage at the time, which included Superphosphate. there are graphs which I can't include here because of the no attachment rule but from the numbers supplied you can draw your own up. OK water control is zero,D1-4,D2+1,D3+2,D4+6,D5-4,D6+4,D7-1,D8+3,D9+2.5,D10+4,D11+5.5,D12+3.5,D1 3+3,D14+4,D15+2.5,D16-3 To me these numbers say that the low potencies (of superphosphate) up to D7 are unstable and dangerous, growth response is up -down - all over the place. From D8 to D15 is an area of stable positive response with a peak at D11 which was also the peak of root growth. This is the sort of pattern that I look for in the Kolisko's results, there is a little safety margin here to allow for differences in the material being potentised, the changes in seasonal effects, and the vagaries of the actual potentisation process. On this graph there is another similar series at the higher end of the potency scale.(for James) D49-3,D50=0,D51+3,D52+4,D53+5,D54+4,D55-2,D56-4,D57-6 just not quite as much margin for error here. I am not recommending potentised superphosphate here just using this graph because it best illustrates what I look for in this work.
[(6) Superphosphate FIG. Sl.-Graph of an experiment with wheat, Ist-60th potencies. This is the most commonly used phosphatic fertilizer. The water control plant indicates only a small "light influence," the first and second leaves are very close together. The 2nd potency already produces a plant which is even better than the water control. Of course, there is only a small difference. The 3rd is much better, and we see quite distinctly that the second leaf is longer than the first one, that shows light influence. The 4th potency is much too big and is immediately followed by a very tiny plant. This is a clear picture of a shock. It is as though you push a pendulum very hard, so that it swings violently to the right; then it happens quite by itself, that it has to swing as violently to the left. Therefore we could never suggest using, for instance, such a low potency of superphosphate. The effect on the plant is not favourable. The 11th potency is the first maximum, the 16th the first minimum, the 29th the second minimum, the 49th the third minimum and the 57th the fourth. The 53rd potency is the second maximum. The roots show the first minimum at the 7th, the second at the 29th, and the third at the 57th potency. It is quite interesting to see that nearly all potencies produce a "light" effect, only the minima indicate a "darkness" effect.] 65 Silica and light next Cheers all Lloyd Charles
