METHOD FOR DETERMINING TOXICITY OF SOIL WITH CHEMICAL SUBSTANCES

摘要

FIELD: agriculture. SUBSTANCE: method involves determining number of springtails under each cultivated crop within rotation system at time interval of 30-40 day and soil moisture content of 60-70%; determining soil toxicity by reduced number of specimens. Method allows toxicity of different types of soil to be determined without conducting chemical analysis within rotation system, when intensified soil technologies are used. EFFECT: provision for obtaining precise and reliable data on soil toxicity and simplified method. 2 tbl, 2 ex
