Nematodes present high potential as a biological indicator of soil quality. In this work, it was evaluated relations between soil physical properties and nematode community under sugarcane cropping and remaining of Atlantic Forest areas in Northeastern Pernambuco, Brazil. Soil samples were collected from September to November 2009 along two 200-m transects(More)
In the Northeast of Brazil, expansion of guava crops has been impaired by Meloidogyne enterolobii that causes root galls, leaf fall and plant death. Considering the fact that arbuscular mycorrhizal Fungi (AMF) improve plant growth giving protection against damages by plant pathogens, this work was carried out to select AMF efficient to increase production(More)
This research was conducted to evaluate three housing systems for broiler chicken production, aiming to characterize thermal environment and animal performance. The experiment was conducted over 42 days, developed in production modules, divided in 15 boxes with 10 birds per box, and submitted to three housing systems: semi-confined with 3 m2 per broiler of(More)
Studies of nematode assemblages in natural ecosystems can contribute to better understanding of the occurrence, relevance, and ecology of plant-parasitic and other soil nematodes. Nematode assemblages and environmental parameters (organic matter, water content (WC), bulk density (BD), total porosity (Po), soil respiration, and soil texture) were(More)
The purpose of this study was to determine the influence of land use types on nematode assemblage in sugarcane production in Pernambuco State, Brazil. One forest and two managed agricultural soils were characterized by their nematode assemblages to assess their biological characteristics. Soil samples were collected between 2009 and 2010 at three 10-cm(More)
The damage caused by Meloidogyne and Pratylenchus nematodes is included among the factors that limit growth and sustainability of sugarcane production. The objective of this study was to assess the seasonal changes and relationships between plant-parasitic nematode communities and plant variables (leaf chemical analysis and growth parameters) in sugarcane(More)
Preconsolidation stress (σ p) is an important physical indicator of the load-bearing capacity of soil, which is used for predicting agricultural trafficability. This study aimed to compare prediction models for agricultural trafficability using soil physical attributes as explanatory variables on soils of coastal lands cultivated with sugarcane in the(More)
