The total acidification in the 0-0.30 m layer was obtained from the sum of acidifications in each of the 6 layers.
Cropping systems and N fertilisation affect soil acidification mainly due to the removal of alkaline plant material from the field and nitrate leaching.

Soil acidification occurs under natural and agricultural ecosystems and is directly related to the carbon (C) and nitrogen (N) cycles in the soil.
2000) and, therefore, can affect soil acidification rates.
In addition to the biological fixation of N, this element can be added to the system through application of N fertilisers, which can have a significant effect on soil acidification. In this case, 2 aspects are fundamental in relation to soil acidification.
Understanding soil acidification processes and determining the most relevant cause factors in each agricultural system is fundamental to the development of strategies to decrease soil acidification rates.
The pHBC was then used to estimate the total acidification in each soil layer by using the equation adapted from Helyar and Porter (1989):
Acidification (kmol [H.sup.+]/ha) = [DELTA]pH x pHBC x MR (1)
Once the buffer capacity for each soil treatment was obtained and the total acidification in the 0-0.30m layer during the period of 19 years was estimated, the framework of Helyar and Porter (1989) for modelling soil acidification was used to estimate the absolute contribution of the N cycle in total soil acidification, as well as to estimate the relative contribution of each component to soil acidification:
The acidification related to the C cycle in the present study was estimated taking into account the acidification due to the removal of corn grain from the field and the shifts in organic matter contents in soil during the 19 years.
The acidification associated with grain removal was converted to CaC[O.sub.3] equivalent by assuming 0.5 Mg CaC[O.sub.3] is required to neutralise 10 kmol [H.sup.+] (Fenton and Helyar 2002).
