1. Precision farming - evaluating soil attributes in productivity and quality of irrigated rice seeds / Agricultura de precisão - aplicada a fertilidade do solo para produção de sementes de arroz irrigado (Oryza sativa L.)
This paper resulted from the analysis of three harvests in a row of the following crops: 2003/2004 rice harvest; 2004/2005 soybeans harvest; 2005/2006 rice harvest, as well as the 2005/2006 post-harvest rice crop (Oryza sativa L.) on Granja do Salso (Salso Farm) in Sta. Vitória do Palmar county, R.S. with the purpose of applying precision agriculture to soi

3. SENSOR SYSTEMS FOR MAPPING SOIL FERTILITY ATTRIBUTES: CHALLENGES, ADVANCES, AND PERSPECTIVES IN BRAZILIAN TROPICAL SOILS
ABSTRACT Soil fertility attributes have different scales and forms of spatial and temporal variations in agricultural fields. Adequate spatiotemporal characterization of these attributes is fundamental to the successful development of strategies for variable rate application of fertilizers, enabling the classic benefits of precision agriculture (PA).

4. Sampling Layer for Soil Fertility Evaluation in Long-Term No-Tillage Systems
ABSTRACT In no-tillage (NT) systems, there is no plowed layer since the soil is not tilled. Thus, the soil layer for fertility evaluation can be defined as the one in which the fertility indices are affected by the surface application of lime and fertilizers and soil properties have the closest relationship with crop yields. The objective of this study was t

6. Técnicas de agricultura de precisão aplicadas ao manejo da adubação na rotação arroz irrigado com soja
The irrigated rice is common and important to the agricultural scenario of RS, however the spatial variability and low fertility of soils associated with some difficult weed control in this crop provided the use of crop rotation practices with soybean. The rotation with soybean can increase the production and to improve the soil fertility by fertility maps,

10. DIAGNOSIS AND SPATIAL VARIABILITY OF SOIL FERTILITY AND CROP PRODUCTION IN A TEAK AREA IN EASTERN PARÁ STATE.
ABSTRACT This study aims to generate the diagnosis and spatial variability maps of soil fertility attributes, as well as teak (Tectona grandis L.f.) production through geostatistics. The study was conducted on a commercial farm in the municipality of Capitão Poço, state of Pará, Brazil. Soil and yield data were collected from 155 sampled georeferenced poi

11. Monitoramento do uso da terra e dos níveis de nutrientes do solo no Sistema Integrado de Produção Agroecológica utilizando geoprocessamento. / Monitoring of land use and soil nutrients levels on an integrated agroecological production system by image processing.
Agroecological production systems are more complex than conventional ones, since a series of crops follow in sequence or are intercropped to achieve high diversity and maximize soil nutrient recycling. The full understanding of these systems require systemic analyses and therefore, adequate tools. To understand soil fertility evolution, heterogeneity should

12. Manejo da calagem e da adubação fosfatada para a cultura da mandioca em solo de cerrado.
ABSTRACT: Soil acidity and soil phosphorus deficiency may be constraints factors to cassava production in cerrado soils. Therefore, the cultivation of cassava requires the adequate management of soil acidity and fertility, by the using of the appropriate combination of lime and phosphate fertilizer. Field experiments were carried out combining lime and phosp
