Abstract


The usual potato production system restricts cultivation in the same area for consecutive years. In order to overcome this limitation, a deep tillage system was developed with the incorporation of organic material. The objective of this work was to evaluate the microbial activity of the soil submitted to different soil management, with and without the incorporation of Panicum maximum; Brachiaria brizantha and maize for the cultivation of potatoes. The incorporation of P. maximum was able to maintain the microbiological activity of the soil stable during the cycle. The deep preparation presented higher potato productivity compared to the usual tillage.
