Resumo: | The historical evolution of the physical properties of a dystrophic oxisol (Goiás, Brazil) was evaluated in a pasture area derived from an original Cerrado opening. This pasture was established by applying 1.5 t ha-1 of calcitic lime and direct sowing of Brachiaria decumbens. After ten years, this pasture was reformed by Barreirão System. In a single operation, the rice sowing was realized at 3-5 cm depth together Brachiaria brizantha mixtured in the fertilizers at 8-10 cm depth, respectively. The evolution of the physical properties was monitored in renovated 1-6 years areas where the system was implanted, using as reference an area of native forest and another 17 years old traditional pasture. According to the obtained data, it was permitted to conclude that there is an inverse relationship among the production of green matter and medium resistance to penetration of the impact penetrometer at drought period, in 8-16 cm depth layer, with a critical level of 2.22 MPa. KEY-WORDS: Tropical pastures; Brachiaria; soil compaction; cerrado soils. |

Avaliou-se a evolução histórica das propriedades físicas de um latossolo vermelho-escuro, distrófico, fase cerrado, textura média, em uma área de pastagem proveniente da abertura do cerrado original. Esse pasto foi reformado aplicando-se 1,5 t ha-1 de calcário calcítico e semeio direto com Brachiaria decumbens. Após dez anos de uso, renovou-se esta pastagem através do sistema barreirão. Estas áreas foram corrigidas com 2,0 t ha-1 de calcário dolomítico. Em uma única operação, fez-se a semeadura do arroz e da Brachiara brizantha mais a adubação, nas profundidades de 3 a 5 cm e de 8 a 10 cm, respectivamente. A evolução das propriedades físicas foi monitorada em áreas com um a seis anos de implantação do sistema, tendo como referências uma área de mata nativa e outra com 17 anos de pastejo tradicional. Os dados obtidos permitem concluir que existe uma relação inversa entre a produção de matéria verde com a resistência média à penetração na época seca, na camada de 8 a 16 cm de profundidade, com um nível crítico de 2,22 Mpa.
