Summary
Agricultural fields near forest fragments can affect soil conditions and, consequently, trees’ metabolism close to the edge, which may lead to long-term changes in the forest composition. Monitoring metabolic changes in forest species may anticipate the impact of agriculture on the forest, and checking the chemical traits of the soil may help elucidate the mechanisms leading to these metabolic changes. Considering that, we evaluated the soil chemical traits and markers of the nitrogen metabolism in trees of three shade-tolerant species at the edge close to a corn field and at 5 points to the interior of a forest fragment in Londrina, State of Paraná. The soil chemical traits did not differ between the edge and the points closer to the interior, except for one point - at circa 150 m of distance from the edge - that showed higher pH, Ca, effective cation exchange capacity, and base saturation. The leaf protein content of the three species was not affected by the proximity to the corn field. Differently, the nitrate content of the leaves was higher at the edge for one species, Guarea kunthiana A. Juss. These results suggest that the corn field near this fragment did not change the chemical traits of the soil, consequently not affecting the protein accumulation of the leaves. However, the nitrate accumulation in one species may suggest that this is a candidate for monitoring the influence of agricultural areas near forest fragments.
