Efeitos da intensificação agrícola na fertilidade de solos e composição florística de remanescentes florestais

The present study aimed to identify the impact of conventional agricultural practices on soilfertility and its consequences on floristic composition of nearby forest fragments. The studywas carried out in 14 forest fragments, where a forest inventory was taken and soil sampleswere submitted to fertility analysis. The results showed Mg, Ca and P values were 2 to 8 timeshigher in small fragments (about 8 ha, near intensive agriculture area). Non-metric multidimensionalscaling (NMDS) showed a change in the floristic community due to proximity. The studyevidences that the intense adoption of inputs in cultivated areas, provoke impacts that gain thebreadth of the landscape scale, proving the demand of policies that support regional strategiesof agroecological transition and the potential impacts of the adoption of land-sparing strategies.
