Floristic characterization of seedbanks under Integrated crop-pasture systems

摘要

The effect of cultivation systems, tillage and fertilization levels on the floristic composition of seedbanks was evaluated at three cultivation systems (continuous crop, crop-pasture-crop, pasture-crop-pasture), two tillage systems (tillage and no-tillage) and two fertilization levels (corrective and maintenance), and a continuous pasture area under no-tillage and corrective fertilization. Cultivation and tillage system were the most important factors affecting the floristic structure of seedbanks. Besides, corrective fertilization increased the number of families and species in relation to maintenance fertilization.
