Short summary

Fixation pattern and kinetics of chelated and non-chelated Cu compounds in semiarid soils were examined. 22% more Cu was fixed in the non-chelated system within the first 14 days (difference of only 7% by day 90). The slope of change in Cu in respect to other nutrients was higher in the non-chelated system. Fixation of Cu was better described by the power function and second-order models in the non-chelated and chelated systems, respectively. Findings are vital for improved nutrient management.
