Land use conversion is a key factor in the mitigation of GHG emission. Maximum mitigation can be achieved when degraded pasture land is converted to biofuel crops. Remote sensing images, and in particular the MODIS time series data, have a great potential to asses degraded pasture land. This work has the objective to identify pasture land and its different levels of degradation in Mato Grosso do Sul state, Brazil. MODIS time series were used to obtain vegetation indices and fraction images. The wavelet technique was applied at various levels of decomposition to extract the input parameters in the WEKA J48 classifier. Pasture land was well distinguished from Cerrado. The distinction among different pasture land presented lower performance with best results for pasture with invasive plants followed by good pasture. Pasture land with bare soil patches and termite mounds were not distinguished from other classes of pasture. made it possible to reduce pasture land without herd reduction. Consequently more land became available for sugarcane. Considering that land use change is a key factor for the benefit of biofuel production to mitigate carbon emission, this benefit can be even higher if sugarcane expansion occurs on degraded pasture land. Remote sensing images have a great potential to evaluate degraded pasture land although is not a trivial task and requires intensive fieldwork. MODIS time series data transformed into vegetation indices or linear spectral mixing model are suitable to represent different pasture land conditions. Under these considerations this work has the objective to use MODIS time series to identify pasture land and its different levels of degradation in Mato Grosso do Sul state, Brazil.

Foi realizado um experimento em casa de vegetacao para estudar a contribuicao individual de quatro especies de fungos micrrizicos arbusculares nativos no crescimento da soja adubada com nitrogenio ou inoculada com Rhizobium em latossolo vermelho escuro de Cerrado. O solo coletado na camada aravel foi esterilizado a vapor e recebeu calcario e adubacao basica. Nos fungos MA foi utilizado inoculante puro e misto de Glomus occultum, Glomus sp. CPAC 2, Glomus sp. CPAC 3 e Glomus sp. CPAC 4, sendo que os tratamentos nao inoculados receberam um filtrado do respecitvo inoculante. Uma parte do solo recebeu adubacao nitrogenada e, nos tratamentos com Rhizobium, o inoculante de Bradyrhizobium japonicum foi aplicado em forma liquida, apos o transplantio das plantulas de soja. Todas as especies de fungos MA promoveram um aumento significativo na absorcao de fosforo e no crescimento da soja, sendo que as tres especies de Glomus sp. foram significativamente superiores ao Glomus occultum. A adubacao nitrogenada foi superior a inoculacao com Rhizobium, na ausencia dos fungos MA. Entretanto, a presenca dos fungos MA igualou e maximizou os efeitos desses dois tratamentos, com incrementos significativos no teor de nitrogenio nas plantas e na producao de materia seca da soja. |
