1. VARIATIONS OF ELEMENT CONCENTRATIONS IN ROOTS OF DIFFERENT TREE SPECIES
ABSTRACT Element concentrations of roots play an important role for plant growth and below ground biochemical cycles in forest ecosystems. It can show a change among species. This research aimed to determine changes in the nutrient content for different root diameters of trees in the Belgrad forest. Natural species of Sessile oak (Quercus petraea L.), Scots

2. Tolerance of Eucalyptus and Pinus seedlings to exchangeable Aluminium
ABSTRACT: Tolerance to acid soil is an important trait of Eucalyptus and Pinus species introduced into commercial forestry plantations in tropical ecosystems. The objective of this study was to evaluate the effect of the exchangeable Al on growth of the seedlings of two species and one hybrid of Eucalyptus and two species of Pinus. We also wanted to identify

3. Biochar in sugar beet production and nutrition
RESUMO: O processo de pirólise da biomassa pode ser uma alternativa para o uso agrícola de lodo de esgoto. Este trabalho objetivou avaliar o uso de biochar produzido a partir da mistura de lodo de esgoto e bagaço de cana (BB, 1:1 relação lodo de esgoto e e bagaço de cana) na produção e nutrição de beterraba (Beta vulgaris L.). Conduziu-se um exper

4. First Assessment of Carbon Stock in the Belowground Biomass of Brazilian Mangroves
ABSTRACT Studies on belowground roots biomass have increasingly reported the importance of the contribution of this compartment in carbon stock maintenance in mangrove forests. To date, there are no estimates of this contribution in Brazilian mangrove forests, although the country has the second largest area of mangroves worldwide. For this study, trenches d

5. Estoque de combustível fino e decomposição de folhas em florestas de igapó do rio Negro / Fine fuel load and leaf decomposition in Rio Negro floodplain forests
In years of low rainfall, fires have occurred in Amazonian black-water floodplain forests, including the Middle Rio Negro. The fires are documented from satellite images. Forest fires require ignition sources, fuel and dry weather. To understand the susceptibility of these forests to fire we investigated the stock of fine fuel on the ground at 29 sites in bl

6. DISPONIBILIDADE HÍDRICA NA PRODUÇÃO DE GIPSOFILA (GYPSOPHILA PANICULATA) EM VASOS COM SUBSTRATO DE CASCA DE ARROZ CARBONIZADA / WATER AVAILABILITY ON GIPSOFILA (GYPSOPHILA PANICULATA) GROWING IN POTS WITH SUBSTRATE RICE HUSK CARBONIZED
Ornamental plants in general are highly susceptive to water deficiency, principally to the elevated soil water level variation that effects at a precarious and uneven final product development. The study was conducted on greenhouse at the Universidade Federal de Santa Maria, RS. It aimed to observe if rice husk ash substrate offers limitation to the pot cult

7. Potassium supply to cotton roots as affected by potassium fertilization and liming.
Cotton (Gossypium hirsutum) is known to have a high requirement for K and to be very sensitive to low soil pH. Most of K reaches plant roots by diffusion in the soil. As K interacts with Ca and Mg, liming can interfere in K movement in the soil, affecting eventually the plant nutrition. The objective of this work was to study the effect of dolomitic lime and

8. Thiamethoxan on sugar cane, common bean, soybean, citrus and coffee plants: parameters of development and biochemical aspects / Tiametoxam em plantas de cana-de-açúcar, feijoeiro, soja, laranjeira e cafeeiro: parâmetros de desenvolvimento e aspectos bioquímicos
Insecticides and fungicides are often studied to their efficiency in controlling pests and diseases, however can cause physiological effects little known that can affect crop growth. Thiamethoxan is a systemic insecticide from the neonicotinoid group, nitroguanidine family, which acts on nicotinic acetylcholine receptor of insects, damaging their nervous sys

9. DESENVOLVIMENTO INICIAL DE UM PLANTIO MISTO DE Eucalyptus urograndis E Acacia mearnsii EM SISTEMA AGROSSILVICULTURAL / INITIAL GROWTH AND PRODUCTIVITY IM MONOSPECIFIC AND MIXED STANDS OF Eucalyptus urograndis AND Acacia mearnsii IN AN AGROFORESTRY SYSTEM
Understanding the initial development in consortiated systems are vital to decide about practices to obtain a sustainable productivity, in relation to environmental resources in an agrossilvicultural site. Due to this, this study had as objective: - to evaluate the agricultural productivity in agroforestry systems with different arrangements of the forest sp

10. Influence of luting agents on time required for cast post removal by ultrasound: an in vitro study
OBJECTIVE: This in vitro study evaluated the influence of luting agents on ultrasonic vibration time for intraradicular cast post removal. MATERIAL AND METHODS: After endodontic treatment, 30 roots of extracted human canines were embedded in resin cylinders. The post-holes were prepared at 10 mm depth and their impressions were taken using autopolymerizing a
