Plant description

On the following pages, experiences are compiled on which plants can form crop marks at which time of the year and at which stage of their development. A few example pictures are shown in each case. The times given for sowing and maturing of the individual plants are of course dependent on the region and the climatic conditions in the respective years and are therefore only to be understood as approximate indications.

Not all pages are currently available in English, the German version can be found here.
