Soybean cotyledons, recently dehulled, were soaked at 50 C for 12 h as a pre treatment to obtain defatted soy flour enriched in aglycones. Grains of cultivar BRS 213 from the crop years 2004 and 2005 were used and initially had 1.4 and 1.2 mg g1 of total isoflavones, respectively. The molar mass of malonyl and bglycosides decreased after soaking (33% and 56.5%, in grains from the crop years 2004 and 2005, respectively), while the aglycones daidzein and genistein, that were previously undetectable, increased to 0.5 and 0.8 lmol g1 in grains from the crop years 2004 and 2005, respectively. Cotyledons treated with the reduced volume of water had a reduction of 4% of the total isoflavone molar mass while, for the cotyledons treated with higher volume of water, there was a reduction of 14%, due to the leaching of isoflavones to the soaking water. |

Shifting cultivation is a traditional land-use system to ensure livelihood in the Northern Amazon. Here, we evaluated how intensification of shifting cultivation (SC) affects secondary forest recovery in the northern Amazon forest. To measure intensity of shifting cultivation, we used the number of previous SC cycles. We selected three study sites containing second-growth forest (SG) with different stand ages (5 and 10 years) after one, three or six SC cycles. Furthermore, we selected old-growth forest (OG) in each study site. In each selected SG and OG, three plots of 20×50m were established, totalizing 63 plots in the study area. In each plot, all trees, palms and lianas with diameter at breast height≥5 cm were tagged and identified to species level. We analyzed the effects of SC intensification and soil fertility on woody species richness, species composition and basal area using mixed effect models. Species richness and basal area, lower in SG than in OG, increased with regeneration time after abandonment, but reduced with intensification of SC. Community dissimilarities (Bray-Curtis distances) between OG and SG increased with the number of shifting cultivation cycles. Soil fertility differed between SG with different regeneration stages and reduced with number of SC cycles. We found that soil fertility and management intensity, i.e., number of previous SC cycles, explained pattern observed in richness, species composition and basal area equally good. Due to nutrient exports with crops and increasing nutrient leaching, soil fertility is expected to reduce with SC intensity. Therefore, our data indicate that intensification of SC reduces recovery of species richness, composition and basal area of SGs following productive periods. Thus, the intensification of SC reduces the resilience of SGs, turning this ancient form of land-use unsustainable. Environmental sustainability of SC may be achieved by extending fallow periods, limiting the maximum yield. To attend growing demands of indigenous and non-indigenous communities, we propose other alternatives of land-use such as permanent agroforestry systems.
