In order to answer these questions, we selec ted a series of fields that participated in the program in four municipalities of the Precordillera and in one municipality of the Andes Cordillera. At Lonquimay P-Olsen was initially increased, showing a positive short-term effect of the program, but gradually decreased after the first year, until it returned to the initial level.

That flora consisted mainly of grasses Agrostis capillaris, Holcus lanatus and some naturalized legumes plants e. Finally, overgrazing caused also problems of erosion.

In each area, we selected fields that had not been subjected to the program these old permanent grasslands were considered to represent the soils in their natural, poor fertility status, and therefore these soils were used to estimate the baseline or “initial” soil test values for the properties considered in this study.

In a similar way ls liming, the phosphoric fertilization must be part of a global strategy for impro ving P availability. Chilean Journal of Agricultural Research 71 2 Finally, the productivity and the quality of the pasture should benefit from the decrease in pH arrow 6the decrease of exchangeable aluminium arrow 5 and the increased availability of phosphorus arrow 4.

This program has been operational for more than a decade. For example, new methods of nitrogen fertilization, based on a nitrogen balance, should be spread and the use of urea should be avoided.

Application of the program had different effects on the pH of the soil in xe different locations studied Table 3. Our method was based on the comparison of native pastures with farmers’ grasslands after they have received, 1 to 4 years before our survey, the program actions.

In those locations, phosphorus uptake by grasses was hampered by the presence of free aluminium.
