Early Effects of Two Productive Systems about the Quality of a Hapludoll from Formosa

Abstract
There have been many changes in the use of soil in the northeast of Argentina for years, with relevant progress in the annual crops in competence with the traditional uses of the ground, a process that some authors call agriculturization. The goal of this work was to quantify, after five years of clearing, the effects of handling two systems over the Hapludoll from the central region of Formosa, Argentina. Three uses of the soil were analyzed: native degraded forest (NF), considered as a witness situation; continual agriculture in direct sowing (CA), and cattle raising (CR)in implanted pasture. Six possible quality indicators were used: pH, oxidizable organic carbon (OOC), particulate organic carbon (POC), structural stability (SS), total nitrogen (TN) and bulk density (BD). The POC resulted the more affected indicator in CA and CR. The variables pH, OOC, POC, SS and BD resulted early indicators in the loss of soil quality. The continual agriculture in direct sowing produced the largest damage in the edaphic system. Five years of implanted pasture only mitigated the deterioration of the soil, without making improvements on the soil quality itself with respect to degraded native forest.
