It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.
Presowing tillage when growing winter wheat under irrigation conditions must be done in relation to the weather conditions. Under favorable conditions, presowing cultivation to a depth of 8–10 cm is recommended. This promotes optimal soil density and maximum yield of winter wheat (up to 48.9 centners/ha). In dry years, the given presowing tillage methods didn’t have a substantial effect.
