This study constructed a fire risk map for the Serra de São Domingos Municipal Park (SSDMP), southern Minas GeraisSate, Brazil, which harbors Atlantic Forest remnants and endangered species. Geo-processing techniques were used producing preliminary altimetry (a), land slope (e), orientation (d), land-use/cover (u) influence of roads buildings (i). After, maps overlaid to produce structural index (SFI)-based Park. The SFI was calculated by using formula = 0,35i + 0,30u 0,15d 0,10a 0,10e....
Acacia mangium and Mimosa caesalpiniaefolia are fast-growing woody fabaceous species that might be suitable for phytoremediation of arsenic (As)-contaminated sites. To date, few studies on their tolerance to As toxicity have been published. Therefore, this study assessed symptoms in A. M. seedlings under stress a greenhouse. Seedlings were grown 120 d an Oxisol-sand mixture with 0, 50, 100, 200, 400 mg kg-1 As, four replications randomized blocks. The plants visible symptoms, dry matter...
This study presents an evaluation of the viability using protected urea under different irrigation depths to reduce nitrogen losses caused by volatilization ammonia (NH3) conditions Southwestern Amazon. The was carried out at Experimental Station Embrapa Rondônia, in municipality Porto Velho, Rondônia State, Brazil. experiment conducted a Red-Yellow Latosol and arranged 5 x 6 factorial design consisting combination five treatments (N sources) with six depths. sources N were as follows: 1)...
Abstract A greenhouse experiment was carried out to evaluate chromium (Cr) toxicity in urograndis (Eucalyptus urophylla S. T. Blake x grandis W. Hill ex. Maiden). Chromium nitrate amended Clark's nutrient solution (0.00, 0.04, 0.08, 0.16, 0.32 and 0.64 mmol L−1 Cr), which used breed one cutting per pot (four replications). Regression analysis revealed that Cr rates of 0.08 or higher significantly decreased (P < 0.01) dry matter yield shoot root. accumulation order plant was: root > stem...
RESUMO – O sistema plantio direto é uma estratégia sustentável de produção que preconiza a manutenção da cobertura vegetal como prática conservacionista do solo. Objetivou-se avaliar o efeito plantas sobre atributos fisiológicos e agronômicos milho na região sudoeste Amazônia. Foram avaliadas 15 estratégias sucessões culturas com influência rendimento biomassa, grãos, altura inserção espiga, índice massa 100 teor foliar nitrogênio clorofilas total, b em milho. Observou-se das biomassa fresca...
ABSTRACT The Orinoco region, is the one with largest area for forest development. Nonetheless, some of its soils are acid and characterized by low fertility levels, which has considerably limited plantation productivity. Therefore, this study aimed at assessing effects soil fertilizing liming using phosphorus potassium on 34-month-old Eucalyptus pellita Tests have been carried out at: Villanueva, Casanare; Puerto Lopez, Meta La Primavera, Vichada, under a random block design factor...
Abstract: The objective of this work was to analyze the spatial variability soil physical attributes in integrated production systems and its relationship with growth yield a corn (Zea mays) crop intercropped palisade grass (Urochloa brizantha). experiment carried out an crop-livestock (ICL) system crop-livestock-forestry (ICLF) system, Plinthic Hapludox. ICLF managed alleys between eucalyptus (Eucalyptus spp.) rows, spaced at 18, 30, 42 m. Corn grain forage yields were positively correlated...
This study aimed to compare the spatial and height distribution of three plant species between two rupestrian field communities, one preserved (A) other cultivated (B). One 50 × 100 m plot was delimited in each community populations Eremanthus incanus, Lychnophora pinaster Vellozia caruncularis were assessed for (using Ripleys’s L-function). In A, 4,098 individuals counted, mostly L. pinaster, against 220 B, prevailing E. incanus. An inverted-J pattern observed both however, with lower...
A cultura do café está sujeita ao ataque de pragas que podem afetar o desenvolvimento e a produção das plantas, sendo relevantes alternativas controle insetos diminuam os efeitos adversos inseticidas como emprego plantas uso seus componentes químicos com ação inseticida. Este trabalho visou avaliar extratos botânicos Piper carniconnectivum, permucronatum, tubercullatum, umbellatum, Cecropia sp., Cymbopogon citratus, Eucalyptus citriodora, Vismia guianensis no da broca-do-café.

Regardless of their ecological importance, riparian forest strips are frequently suppressed to allow greater expansion arable and urban areas. Agroforestry might be an effective alternative recompose forests. Soil chemical microbial properties important environmental indicators evaluate the reclamation process. This study tested hypothesis that, in course time, reforestation by means agroforestry improved soil a buffer. samples were collected from three layers (0.0-2.5; 2.5-7.5; 7.5-20 cm)...
Com o objetivo de avaliar os efeitos da toxidez cromo (Cr) sobre crescimento e desenvolvimento mudas Eucaliptus urophylla, foi instalado um experimento em casa-de-vegetação no Departamento Ciência do Solo Universidade Federal Lavras. Foram utilizadas diferentes concentrações Cr (0,00; 0,04; 0,08; 0,16; 0,32 0,64 mM) fornecido como [Cr(NO3)3.9H2O], solução nutritiva Clark. Após cinco semanas exposição aos tratamentos, as plantas exibiram sintomas traduzidos redução crescimento, queda folhas,...
