1. Crop coefficient and water requirement of prickly pear in the Agreste region of Alagoas state, Brazil
RESUMO O cultivo da palma forrageira tem exercido papel importante na pecuária brasileira, sendo utilizada como forragem para os animais na região Nordeste, especialmente na época de escassez de chuvas, por ser uma excelente fonte de água. Deste modo, objetivou-se com o esse trabalho estimar o coeficiente de cultivo e a necessidade hídrica da palma forr

2. Leaching of Imidazolinones in Irrigation Systems in Rice Cultivation: Sprinkling and Flooding
RESUMO: Herbicidas do grupo das imidazolinonas têm sido utilizados em arroz irrigado e apresentado longa persistência no solo, principalmente em áreas de várzea, com baixa drenagem, podendo ocasionar contaminação ambiental. Objetivou-se, com este trabalho, avaliar a lixiviação e o residual dos herbicidas pertencentes ao grupo das imidazolinonas em si

3. Physical Properties and Crop Management for Corn in an Albaqualf
ABSTRACT Rice monoculture in lowlands can cause problems for management practices in crop fields, for example, in weed control. For this reason, corn in rotation with irrigated rice in lowlands may be advantageous, despite problems with soil compaction and water excess. The objective of this study was to evaluate soil physical properties and corn performance

4. Slow sand filtration eradicates eucalypt clonal nursery plant pathogens from recycled irrigation water in Brazil
Contaminated irrigation water constitutes one of the main sources of plant pathogens that can cause disease and lead to potentially significant production losses in forest nurseries. Recycling of contaminated irrigation water increases the risk of spreading diseases. The objective of this study was to evaluate a simple slow sand filtration treatment of irrig

5. Caracterização de resíduos sólidos da construção civil para sua utilização em camadas drenantes de aterros sanitários / Characterization of construction waste for use as drainage materials in sanitary landfills
Intense population growth brings with it environmental concerns, since exploitation of natural resources, makes it essential to adopt recycling policies in order to achieve sustainable development. Therefore, this study sought to define a new application for recylcling construction and demolition waste (CDW-R). Two size distributions that could be readily pr

7. Sedimentology, stable isotopes and palinology of quaternary deposits from eastern of Marajó Island, Pará State / Sedimentologia, isótopos estáveis e palinologia de depósitos quaternários no leste da Ilha do Marajó, Estado do Pará
Analysis of Quaternary sediments in Amazonia is of great interest for reconstructing the dynamic evolution of its drainage basin, and to support discussions related to paleoclimate, sea level and tectonics. Few studies emphasize this type of approach, which is mainly due to lack of natural exposures due to the low topography of the area. This work integrates

8. Evaluation of field performance of cover systems at Rio Paracatu Mine (RPM) / Avaliação de desempenho de sistemas de cobertura na mina Rio Paracatu Mineração (RPM)
In view of the RPM need to study soil covering systems and the scientific interest in those studies, two experimental evapotranspirative cover systems were projected and built, one with and, the other, without, a layer of capillary barrier, both with a monitoring system composed by superficial drainage meter, lisimeters to measure infiltration and geotechnic

9. Fertirrigation with cattle wastewater in Tifton 85 grass and black oat: effects on soil and plants / Fertirrigação de capim-Tifton 85 e aveia preta com águas residuárias de bovinocultura: efeitos no solo e nas plantas
This study was conducted to evaluate the effects from the application of cattle wastewater (ARB) upon both physical and chemical properties of an Eutrophic Red Argisol and on the physiologic, nutritional and yield characteristics of the 85-Tifton grass (Cynodon spp.) and the black oat plant (Avena strigosa Schreb). The experiment was carried out in 20 draina
