Abstract Previous studies in soils of the Pampas region indicate
the prevalence of calcium phosphates within the very complex mix
of phosphorus (P) compounds in the soils. We studied the changes
in P fractions in a punctual situation in the Pampas region. The sampling
was carried out in a farm located near the city of Junín (-34.585;
-60.9589) and the soil was Junín series Typic Hapludoll. The farm
was devoted to grazing and sporadic crops, but from the last 30 years
changed to continuous agriculture. At no time fertilization matched
nutrients removal by crops. The soil P fractions were determined using… More >
