Field Method For Describing Root Activity Using Stable Strontium As A Tracer, Michael Aaron Krstich

Doctoral Dissertations

Stable Sr was evaluated for use as a tracer for characterizing root growth or root activity of field-grown soybeans (Glycine max (L.) Merr.). Root activity is defined in this study as the absorption of Sr with subsequent accumulation of Sr in the trifoliates. Previous research had established that the amount of Sr absorbed was directly and positively correlated with total root length and root weight in the zone of tracer placement in the soil. A 0.138 mole ratio of Sr(OOCCh₃)₂^.0.5H₂O to SrCl₂^.6H₂O, containing 0.068g Sr ml^{-1 …}
