Land management effects on phosphorus pools in Histosols.

Long -term land management affected the distribution of Phosphorus in soil chemical fractions. Soils under intensive cultivation had a lower proportion (52%) of Phosphorus in the organic fraction compared to non-cultivated (78%). In addition, intensive tillage regime promoted the redistribution of Calcium from subsurface to surface soil, which leads to greater Phosphours sequestration in the Calcium-bound fraction.
