oil amendment with manures from intensive livestock breeding is, currently, a usual practice which could produce positive and/or negative effect on several soil properties. In this work, the effect of consecutive additions of pig slurry (PS), during 1 and 15 years, in two different farms in the Province of Córdoba (Argentina), was analyzed. Also, a control soil (without amendment), and an untilled soil were studied for comparison for each farm. This is the first research to be conducted in this part of the country. In this research we study the effect of PS applications in large commercial pig farms. For all soils and PS samples collected the following parameters: pH, electrical conductivity (EC), total N (TN), available phosphorus (P), Na, K, Ca and Mg, were analyzed. PS presents an alkaline pH, high EC, high phosphorus and nitrogen content. The statistical analysis, shown that PS application for 15 years could significantly modify the soil physicochemical properties, but one PS appl
