1. Achados de fundoscopia de pacientes diabéticos e/ou hipertensos
ABSTRACT Soil compaction in agricultural areas has greatly increased in recent decades due to intensive farming practices, including short-cycle crops and machinery intensification. This study aimed to evaluate the impacts of management systems on the physical quality of a dystrophic Yellow Oxisol, in the Cerrado region of Brazil. Treatments consisted of fiv

4. 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

5. Production and nutrition of irrigated Tanzania guinea grass in response to nitrogen fertilization
The objective of this study was to evaluate the effects of nitrogen (N) fertilization in the four seasons of the year on forage production, nitrate (NO3) in the sap, total N in the forage and relative chlorophyll index (SPAD reading) in the leaves of irrigated Panicum maximum cv. Tanzania grass, establishing their critical ranges. In addition, we evaluated t

6. Matéria orgânica e atributos químicos em solo de tabuleiros costeiros sob diferentes coberturas vegetais / Organic matter and chemical attributes of an Coastal Tableland soil under different vegetation covers
The conversion of native vegetation in agricultural and forest crops results in changes in soil properties. The aimed was to assess the dynamic attributes of a Yellow Oxisol under differents vegetation covers in the Coastal Tableland. Soil samples were collected at depths of 0-10, 10-20 and 20-40 cm in June 2011 in Sooretama, ES, considering four soil vegeta

7. Estudo da dinâmica da solução do solo para o manejo da fertirrigação por gotejamento na cultura do pimentão / Study of dynamics of soil solution for the drip fertigation management in culture of pepper
Among various systems, the drip irrigation has been increasingly used, mainly because of its greater efficiency in water use. This work aimed to study the dynamics of soil solution, characterizing the distribution and storage of nutrients in the soil solution, and their absorption by pepper through the management of drip fertigation with two flows rates. The

9. Efficiency of boron application in an Oxisol cultivated with banana in the Central Amazon.
In the Amazon region, there is no information on the fertilization of banana plants with boron (B). Besides this, the extractant (hot water) currently used to test B concentrations has many limitations. The aim of this work was to study the effect of B on the fruit yield and quality of banana plants of the Cavendish (AAA) sub-group, grown in dystrophic Yello

12. Rochas moídas como fontes de potássio para o milho em solo de cerrado.
RESUMO: Três rochas foram avaliadas quanto à capacidade de fornecer potássio para o crescimento inicial do milho, num Latossolo Vermelho-Amarelo argiloso, em condições de casa de vegetação. As rochas biotita xisto, brecha alcalina e ultramáfica alcalina foram moídas (< 0,3 mm) e comparadas à fonte cloreto de potássio, nas doses de 50, 100 e 150 mg
