1. Nutrition of tree species in tropical dry forest and rainforest environments
ABSTRACT Knowledge of the nutritional efficiency of species can help revegetation of forest areas, guiding the use of species that best adapt to environmental humidity, altitude and diversity. The objective of this study was to evaluate the nutrient utilization efficiency of N, P, K, Ca and Mg of dominant species in tropical dry forest and rainforest environ

2. Controlled-Release Fertilizer on Growth of Melanoxylon brauna Schott Seedlings
ABSTRACT Melanoxylon brauna is a tree species native to the Atlantic Forest of high ecological and economic value. The objective of this study was to evaluate the growth and nutritional status of seedlings of two Melanoxylon brauna cultivars grown in substrate with different controlled-release fertilizer doses (CRF). The experiment was arranged in a randomiz

3. Intercropping Acacia mangium stimulates AMF colonization and soil phosphatase activity in Eucalyptus grandis
ABSTRACT: Arbuscular mycorrhizal fungi (AMF) are very important to plant nutrition, mostly in terms of acquisition of P and micronutrients. While Acacia mangium is closely associated with AMF throughout the whole cycle, Eucalyptus grandis presents this symbiosis primarily at the seedling stage. The aim of this study was to evaluate the dynamics of AMF in the

4. Nutrition facts and limits for micronutrients in tree species used in urban forestry
ABSTRACT There is a huge lack of researches that evaluate the nutritional limits in tree species used in urban forestry, especially in terms of micronutrients. This study aimed to establish limits and range of micronutrients levels for the proper development of tree species utilized in urban forestry. The study was conducted in the city of Santa Maria-RS-Bra

5. Biological Nitrogen Fixation by Legumes and N Uptake by Coffee Plants
ABSTRACT Green manures are an alternative for substituting or supplementing mineral nitrogen fertilizers. The aim of this study was to quantify biological N fixation (BNF) and the N contribution derived from BNF (N-BNF) to N levels in leaves of coffee intercropped with legumes grown on four family farms located in the mountainous region of the Atlantic Fores

6. Study of the physical and physicochemical characteristics of fruits of the licuri palm (Syagrus coronata (Mart.) Becc.) found in the Atlantic Forest of Minas Gerais, Brazil
AbstractThe Atlantic Forest has species of native fruits, consumed fresh and processed, which have an important contribution to food sovereignty of families that consume it. This study examined the physical and physicochemical characteristics, proximate composition, concentration of carotenoids, vitamin C, vitamin E and minerals in the pulp and kernels of fr

9. Ecologia Política da comida e nutrição em duas comunidades quilombolas do Vale do Ribeira (Estado de São Paulo, Brasil) / Political Ecology of food and nutrition for two Quilombola communities from Ribeira River Valley (São Paulo State, Brazil)
Quilombolas are African slave descendants. The Ribeira Valley is one of the most important areas of concentration of Quilombos in Southern Brazil. The Ribeira Quilombolas are settled in remote areas along the Ribeira River system covered by Atlantic rain forest vegetation, one of the worlds biodiversity hotspots. Since the first settlements (18th Century), t

10. Using Macrocystis pyrifera (L.) C. Agardh from southern Chile as a source of applied biological compounds
The exploitation of seaweeds in Chile has been carried out for more than 60 years. More recently, seaweeds have been used for the production of alginate, agar and carrageenan, agricultural fertilizers and industrial aquaculture (feed for abalone and sea urchins), increasing the added value of this natural resource. In the Magellan Region (56ºS), the giant k
