13. Formulation of economical microbial feed using degraded chicken feathers by a novel Streptomyces sp: mitigation of environmental pollution
A new Streptomyces sp. IF 5 was isolated from the feather dumped soil and found to have a tremendous keratinase activity. The strain enabled the degradation of the chicken feathers very effectively in 60 h. The 16S rRNA sequence of 1474 bp long was submitted to the National centre for Biotechnological information. The keratinolytic activity in the culture me

17. AVALIAÇÃO DAS POTENCIALIDADES DAS TERRAS, ADEQUAÇÃO DO USO DAS TERRAS E INDICADORES DE QUALIDADE DOS SOLOS: subsídios para o planejamento conservacionista no perímetro irrigado de Mirorós (Ba). / EVALUATION OF THE LAND POTENTIALS, LAND USE ADEQUACY AND SOIL QUALITY INDICATORS: subsidies for conservationist planning in the irrigated Perimeter of Mirorós (Ba).
The practice of irrigated agriculture represents an increase of agricultural productivity, especially for areas with water deficit. Lands are frequently characterized erroneously which, coupled with lacking conservation measures, imposes serious consequences for the environment. In reality, any land use and intensive soil management when carried out unsustai

18. Macrozoneamento do Estado do Rio Grande do Sul
Earth imaging technologies using orbital platforms have allowed new approaches in the analyses, compartmentalization, and territorial visualization. These cartographic informations have many applications in agricultural, urban and environmental monitoring. In the case of vast geographic regions, such as Brazil, one expects that the many products obtained fro

19. Influence of land usage changes in soil properties in an ecosystem of the Amazon south occidental. / Influência da mudança no uso do solo nas propriedades edáficas em ecossistema da Amazônia Sul Ocidental.
The inadequate land management causes soil degradation, which, if reversible, will require time and resources for recovering. Evaluations of changes in soil properties using soil quality indicators contribute to avoid soils more susceptible to decrease their natural productive capacity. The aim of this study was to verify the influence of changes in land usa

21. Bioensaios com fósforo e indicadores químicos, microbianos e bioquímicos do solo, em áreas sob cerrado, pinus e plantio direto / Phosphorus bioassays and chemical, microbial and biochemical indicators of soil in areas under savannah, pinus forest and no-tillage
The microbial activity in soil has great importance in regulating the processes of transformation of carbon and nutrients, like phosphorus. However, the microbial activity is strongly linked to agricultural practices in land use. In Chapter I, the study aimed to compare three systems of land use in relation to the response of microbial metabolic activity, wh
