In many documents dealing with the issue of Crop Circles occur mention of completely unaffected plants, "foreign" admixed, in cultivated monoculture (aliens lodged (damaged, weakened) only barley, did not act on wheat also present there) - ff course, different moisture content, different resistance, different energy induced, different (lower) level of damage, greener plants may seem completely unaffected.
Sa maraming dokumento pagharap sa ang isyu ng mga lupon crop nangyari banggitin ng ganap na hindi maaapektuhan halaman, "banyagang" admixed, nilinang sa monoculture (alien lodged `ay hindi (nasira, Weakened) lamang barley, ay hindi kumilos sa trigo din kasalukuyan doon) - ff kurso, iba't ibang kahalumigmigan nilalaman, iba't ibang paglaban, sapilitan ibang enerhiya, iba't ibang (mas mababa) antas ng pinsala, greener halaman ay maaaring tila lubos na maaapektuhan.
