摘要: Abstract The effect of carbon dioxide partial preassure on the stability iron chelates in calcareous soils is often laid aside. Theoretical diagrams have been developed showing large importance this compound total solubility from Fe‐EDTA and ‐DTPA chelates. As CO2 increases free Ca2+ activity solution decreases. Then chelation increases. does not change Fe‐EDDHA since percentage 100% all conditions tested for chelate. Experimental data fit theoretical well when high, but ‐free air used, greater than expected. Causes that can produce difference are discussed.
