In the industrial zone of Albiate (Milan), on May 18th 2005 have been found some odd-looking circular signs on a field of grass. Some photos arrive from the site www.croponline.org, which makes to notice the precision with which the ears are addressed to the ground, the verticality of those on the edges and the fact that in many cases there are "isolated" areas of ears folded up to the ground, unattainable without leaving an evident passage. The Cicap (Italian Committee for the Control of the Affirmations on the Paranormal) has written to such intention: Casual sketches? What do you mean? Atmospheric agents as wind, rains or hail, have the tendency to fold up and to lay down to earth the plant provoking the phenomenon called "lodging". With the italian term "ginocchiatura" we refers instead to the ability of the stem to straighten themselves in correspondence of one of the knots in case of lodging (natural cause) or mechanical leveling (for instance due to the human action). Also the nature succeeds therefore to "carve" works in the wheat (they are generally easily recognizable) potentially causing some damages to the crop because the folded up ears do not succeed in easily reaping. We are talking about NGF (that stands for "Not Geometric Formations"), or "Randomly Lodged Formations" or "Randomly Downed Formations". http://www.cicap.org/cropsGeorgio Pattera, biologist and scientific advisor of the C.U.N. writes: "In the case of the NGFs the interpretation furnished by the experts of the CICAP is correct. Also our experience has conducted us to formulate the same explanation, on the occasion of the recovery of a NGF in the place Castelguelfo, near Parma, the 15 May of last year (see database). Particularly we can affirm that this year, because of violent downpours alternate with particularly windy days, the meteorology has "had a good time" to create in the cultivation some irregular zones of "depression", deprived of a any geometric expression. This derives from the fact that the weight of the rain extends to tilt the stem in "geotropa" (horizontally, toward the ground) position; subsequently the gusts of wind "comb" these zones, engraving them a shed disposition, a sort of "fan", entirely asymmetrical. An agronomist of the Catholic university in Piacenza (faculty of Agriculture) questioned by us on the phenomenon, has explained as, in certain cases, an excessive Nitrogen concentration in the ground (consequential from a massive spread of fertilizers, superior to the relationship of equilibrium among% of nitrogenous mixtures and extension of the piece of ground) can conduct to an increase of the ductility of the knots of growth of the stems, favoring in such way their bending under the influence of atmospheric agents. Such folding, nevertheless, is transitory and of brief duration, as the seedling, following the law of the "ortotropismo" (tendency to the erect position), soon it repurchases the correct vertical posture, antecedent the conflicting event."
