The study had the objective to evaluate the effect of the fertilization with filter cake enriched with soluble phosphate on the sugar yield. The experiment carried at Presidente Prudente-SP, used a randomized complete block design, in the factorial scheme 5 x 4, where the first factor consisted of doses of filter cake (0; 0.5; 1.0; 2.0 and 4.0 t ha(-1)) and the second, doses of phosphorus fertilizer (0, 50, 100, 200 kg ha(-1) of P2O5), with 4 replicates, totaling 80 plots. The results indicated that phosphorus applied in planting furrows improves the quality of sugarcane raw matter by increasing the levels of soluble solids, total reducing sugars and sucrose in the stalks. The phosphorus also increases the productivity of sugar. The filter cake applied in planting furrow has the potential to partially replace the chemical fertilization with phosphate aiming to improve the quality and the productivity of sugar. The best combination was filter cake at dose between 2.6 and 2.7 t ha(-1) combined with dose between 160 and 190 kg P2O5 ha(-1) for obtaining best response of soluble solids and productivity of sugar.

Vascular plants were investigated in oxbow lakes of Turvo River, Upper Paraná River basin, between Icém and Nova Granada municipalities, state of São Paulo, Brazil. In this region, six lagoons were sampled: Ganzella, Mustafá, Braço Morto, 45, Federal, and Parente. The survey showed a total of 54 species, 36 genera and 22 families. The species richest families were Poaceae, Cyperaceae, and Polygonaceae. Eichhornia crassipes (Pontederiaceae) was the single species encountered in all the six lakes. © 2010 Check List and Authors.

The Capão Bonito Granitic Massif is situated in the south portion of the São Paulo State and represents an elongate body with general direction NE-SW, intrusive in epimetamorphic rocks of Açungui Group (Votuverava Formation), and in granitic rocks of the Três Córregos Complex. It is partially covered by sedimentary rocks of the Paraná Basin (Itararé Group). As the chief type we have red sienogranite, holo to leucocratic with biotite and rare hornblende, inequigranular with medium to coarse grains to porphiritic and isotropic to slightly cataclastic textures of marginal zones. This granite was analyzed for petrographics (composition, structure and texture), chemical composition (major elements), physical and mechanical (water absorption, resistance to abrasion, impact of hard body and efforts of compression and traction) and chemical attack aspects. The results were compared to suggested values for granitic rocks used for ornamental purposes. The whole massif shows compositional, textural, structural (related to isotropy) and chemical (major elements) characteristics very homogeneous. The varieties of sienogranite named commercially as Capão Bonito or Rubi Red Granite showed results very similar to each other, with some variations in the physical and mechanical resistance resulting of the penetrative brittle deformation of regional occurrence, evidenced by differences in the microfissural index.
