"Buried (syn. sunken, sub-surface and sub-soil) archaeological features on arable land can frequently be discovered due to visually detectable changes in crop growth termed cropmarks. The aim of this paper was to demonstrate the range of features identified through cropmarks on aerial photographs in stands of main field crops in the Czech Republic. Low-altitude oblique aerial photographs of cropmarks were collected from an aircraft from a height of 300e500 m above ground during approximately 800 flight hours from 1992 to 2010. Some features discovered via cropmarks were excavated by standard archaeological methods. Around one thousand cropmarked sites were discovered. The highest density of archaeological sites was on sandy soils in dry lowland regions, and a substantially lower number on loess or clay soils or in regions above 350 m a.s.l. Cropmarks were best developed in barley (Hordeum vulgare), followed by wheat (Triticum aestivum), winter rape (Brassica napus) and lucerne (Medicago sati" .
