Data confidence 70 medium
How this score is calculated

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.

Abstract

Abstract This paper proposes a method for evaluation the relationship between organic matter (humus) and cation content in the soil adsorbing complex and the number of microaggregates determining the soil structure. The method is based on the use of statistical analysis of combined data of water extracts and the amount of microaggregates in soils (serozems and chernozems). The method is expected to enable a more complete assessment of the impact and effects of irrigation on the structure of soil layers.
