Development of technologies and methods for monitoring the spatial variability of air temperature in greenhouse environment
(Pesquisa Aplicada & Agrotecnologia, 2013) [Artigo]
Climatic factors directly influence growth and productivity of plants inside greenhouses, where temperature can be considered one of the major parameter in this context. Thus, the aim of this research was to develop a low ...
Characterization, feasibility and optimization of Agaricus subrufescens growth based on chemical elements on casing layer
(Saudi Journal of Biological Sciences, 2012-07-01) [Artigo]
The aim of this study was to analyze yields, biological efficiency, earliness (expressed as days to first harvest), and precociousness and establish models for the mushroom growing according to these parameters. The ...
Comparison of methodologies for degree-day estimation using numerical methods

Tropical Healthcare Epidemiology: Weather Determinants of the Etiology of Bloodstream Infections in a Brazilian Hospital
(Infection Control and Hospital Epidemiology, 2014-01-01) [Artigo]
We studied the influence of weather on the etiology of healthcare-associated bloodstream infections in a hospital in Brazil during the years 2005--2010. Monthly average temperatures were positively associated with higher ...
Influence of potassium and sodium nutrition on leaf area components in Eucalyptus grandis trees
(Plant and Soil, 2013-10-01) [Artigo]
Background and Aims: Recent studies showed a positive tree response to Na addition in K-depleted tropical soils. Our study aimed to gain insight into the effects of K and Na fertilizations on leaf area components for a ...
Biomass and Stand Characteristics of a Highly Productive Mixed Douglas-Fir and Western Hemlock Plantation in Coastal Washington
(Western Journal of Applied Forestry, 2009-10-01) [Artigo]
Aboveground biomass predictive equations were developed for a highly productive 47-year-old mixed Douglas-fir and western hemlock stand in southwest Washington State to characterize the preharvest stand attributes for the ...
Initial physic nut nutrition and potassium balance in the soil-plant system
(Revista Brasileira De Engenharia Agricola E Ambiental, 2014-05-01) [Artigo]
The objectives of this study were to evaluate the mineral nutrition and the response of physic nut to potassium fertilization as well as to assess whether the species can absorb K from the non-exchangeable soil fraction. ...
Absorção e níveis críticos de fósforo na parte aérea da mamoneira cultivada em diferentes classes de solos
(Semina-ciencias Agrarias, 2014-01-01) [Artigo]
Soil that has a high degree of weathering, with more inorganic P bound to Fe and Al oxides, has less P availability to plants. Thus, the critical element of a plant refers to the level below which the growth rate and plant ...
Sewage sludge levels on the development and nutrition of sunflower plants
(Revista de La Ciência Del Suelo Y Nutricion Vegetal, 2009-01-01) [Artigo]
This study aimed to evaluate the effect of substituting chemical nitrogen (N) fertilization for equivalent N levels from sewage sludge of Wastewater Treatment Plant (WTP) on sunflower plant development. Nutrient levels in ...
