between the alternate strips was quite apparent. Where the copper-
plated plough had been used the water content and the nutrient
energies of the soil had been increased, and the corn stood about
6-8 inches higher with a much fuller head. Some yields in the
strips ploughed with copper-plated implements increased by up to
40% compared to the control strips where conventional steel
ploughs were used. As all other factors of soil chemistry, orienta-
tion, furrow width, etc., were identical, the difference in yield was
clearly due to the use of the copper plated plough.
With two crops there were spectacular results. 15cm long ears of
rye produced an average of 104 grains each (Fig. 16.1). In another
experiment in Tyrolean Kitzbuhel potatoes weighing nearly half a
kilo, containing over twenty eyes' (the source of next year's crop),
were produced (Fig. 16.2).The Bio-plough
The conventional ploughshare forms a pressure wave and makes a
crushing cut that destroys the soil capillaries. Schauberger in 1948
encouraged a Hamburg engineer Jurgen Sauck to develop a sharp
curved blade to create a long slicing cut before the soil is cen-
tripetally involuted in a figure of eight motion through the curving
wings of the phosphor-bronze ploughshare, copying the burrowing218 HIDDEN NATURE
