Scale:

1:20,000,000.

Accuracy of map:

The map was created using maps that had the following scale: 1:25,000,000-1:40,000, 000.

Projection:

"Alber's Equal Area Conic for Russia" 9, 1001, 7, 100, 0, 44, 68, 0, 0

Basic contents:

Vector file consisting of polygons.

Accuracy of classifier:

Polygons are based on literature sources, political boundaries and ecological description.

Method of map production:

The cultivated area of Lotus corniculatus was determined based on agroclimatic, natural and economic principles of former USSR countries territory division. The vast information on the problem published in open press was analyzed. The final map was constructed by generalization of regional maps, arable-lands map (dark blue polygon), map of lands permitted for cultivation without non-arable-lands (light blue polygon). Only those lands where Melilotus albus took place in crop rotation were taken into account.
