| Abstract: | Abstract Extractable li with ammonium acetate was determined by flamephotometry, in normal soils, alkaline soils and saline soils in the Province of La Pampa (Argentina). The soils were originated from differents parent material, with various rainfalls (arid to subhumid climate) and management. The higher contents were found in saline soils. In the other soils the extractable lithium content depends on the parent material, but not on rainfall. Different patterns of vertical and horizontal distribution of extractable lithium were found. The origin of extractable lithium is here discussed. |
