Using indicator kriging for evaluating soil fertility indicators

Made available in DSpace on 2020-12-10T18:05:34Z (GMT). No. of bitstreams: 0 Previous issue date: 2006-05-01; The objective of this study was to identify site-specific management zones by means of chemical soil fertility indicators on sugarcane-cultivated Latosols (Oxisols), using indicator kriging, aiming an optimized use of precision agriculture techniques. The study was conducted in a 90 ha section of a larg...

Ocorrência de Listeria spp. e de Listeria monocytogenes, em um matadouro-frigor...

A ocorrência de Listeria spp. e de Listeria monocytogenes, foi avaliada em amostras ambientais por meio de suabes colhidos em matadouro-frigorífico de bovinos habilitado à exportação, localizado no Estado de São Paulo, Brasil. Após o pré-enriquecimento a 30 ± 1oC por 22 à 26h as amostras foram analisadas empregando o BAX® System Listeria. As amostras positivas para Listeria spp. foram submetidas à uma nova re...

Characterization of Ultisols in different segments present in Jaboticabal, SP

Soil is the product of joint action of the parent material, climate, topography, time and organisms associated with pedogenic processes: addition, deletion, translocation and transformation, which determine the behavior of the soil. Thus, the aim of this study was to characterize Argissolos in different relief features in Jaboticabal, SP. Three trenches were opened in top segments, slopes and foothills, then mo...

Growth of dry bean crop submitted to two water management and tillage systems -...

The dry bean has great importance to Brazilian agriculture. In addition to being a crop that meets the characteristics of family agriculture, it is also cultivated in extensive areas using high technology. Research related to the behavior and development of the bean crop in relation to regional soil and climatic variants have assumed a prominent role, especially because it is a plant that is sensitive both to t...

Spatial variability of co2 emission, temperature and moisture of a bare oxisol ...

The irrigation application is one of the most useful techniques in tropical environments, especially during dry seasons. In this study, CO2 efflux, temperature and soil moisture were studied in a field sampled with a grid having 48 points distributed in 35 x 25 m, under irrigation promoted by a sprinkler located at the center of the area, provoking different levels of water deposition, with maximum irrigation l...

Density and resistance to the penetration of rubber-tree cultivated soil under ...

The influence of different management agricultural practices such as disk harrowing, mowing and use of perennial green fertilizer (Pueraria phaseoloides) between rows of rubber-trees (Hevea brasiliensis) was studied on the penetration resistance of the soil. It was evaluated in different depths in a “Latossolo Vermelho distrófico textura argilosa A moderado caulinítico hipoférrico relevo plano” (LE) in the rura...
