Transformações no uso da terra e na estrutura de solos no cerrado em áreas de expansão da cana-de-açúcar: o caso da microrregião de Quirinópolis, Goiás ; Changes in land use and structure of soils in Savannah in areas of expansion of cane sugar: the case of microregion of Quirinópolis, Goiás ; Cambio en el uso de la tierra y estructura del suelo en Sabana en areas de expansión de la caña de azúcar: el caso de la microrregión de Quirinópolis, Goiás
The state of Goiás stands out in the current process of expansion of Sugar Cane and due to logistical reasons, soil and climatic as well as economic interests its Southern central region is highlighted, with special emphasis on Quirinópolis. The expansion process of sugar cane first occurred in Dystroferric Red Latosol of clayey texture in replacement of areas of annual crop as the second step; once the supply of these areas is exhausted pasture areas in medium textured Dystrophic Red Latosol are replaced. The results confirmed the rapid expansion of planted areas, initially on areas before so... Mehr ...

The state of Goiás stands out in the current process of expansion of Sugar Cane and due to logistical reasons, soil and climatic as well as economic interests its Southern central region is highlighted, with special emphasis on Quirinópolis. The expansion process of sugar cane first occurred in Dystroferric Red Latosol of clayey texture in replacement of areas of annual crop as the second step; once the supply of these areas is exhausted pasture areas in medium textured Dystrophic Red Latosol are replaced. The results confirmed the rapid expansion of planted areas, initially on areas before soybeans, which have been consolidated, and also revealed that the soils had shown high to very high compression risk. It is important to mention the unquestionable degradation of physical quality resulting from this process, supported by known indicators of increased penetration resistance, dispersion of clay and soil density, accompanied by the reduction of the macroporosity and changes in morphoporosity. It is concluded that compression, can be associated with the effects of management practices with heavy machinery, but studies so far, can be mitigated by the use of fertirrigation with stillage. ; El estado de Goiás se destaca en actual proceso de expansión de la caña de azúcar y los problemas logísticos, el suelo, el clima y los intereses económicos de su centro sur se encuentran en esta microrregión de Quirinópolis. En este proceso de expansión de la caña de azúcar se produjo principalmente en Oxisoles dystroferric zonas rojas arcillosas a cambio de la cosecha anual en un segundo momento agotado el suministro de estas áreas, en sustitución de las zonas de pastoreo en distrófica medio textura roja. Los resultados confirmaron la rápida expansión de las superficies plantadas, inicialmente en áreas antes de la soja, que se han consolidado y también revelaron que los suelos se habían citado riesgo alto o muy alto de compresión y la presencia indiscutible de la degradación física que resulta de este proceso, con el apoyo los ...
