From an economic point of view, Brazilian agribusiness has been recognized as modern, prosperous, profitable and competitive activity whose magnitude has established Brazil as a world agricultural power. The activity accounts for 26% of the gross domestic product, 42% of the volume of Brazilian exports, and 37% of the total number of jobs in the country. The finding from this scenario is that development in the country is strongly dependent on an increasing production of agricultural products ...Status: Completed Start date: Mon Apr 01 00:00:00 GMT-03:00 2013 |

One of analytical techniques that enables precise chemical analyzes with speed, low cost and little sample manipulation is near-infrared spectroscopy - NIRS. The interest in NIR spectroscopy has grown remarkably and this technique has been recognized as a powerful tool for quantitative and qualitative analysis of chemical and physical parameters. Besides these features, the methodologies based on NIR spectroscopy have the following inherent properties: 1) allows simultaneous analysis of multi ...Status: Completed Start date: Fri Apr 01 00:00:00 GMT-03:00 2011 |
| Spittlebug, Mahanarva spectabilis (Hemiptera: Cercopidae) is capable to cause drastic losses in production and quality of pastures established with grasses. Currently, the use a grass resistant cultivar, to be obtained by means of constitutive antibiosis, is the best spittlebug controlling method. However, the time required for releasing a cultivar after detecting a spittlebug-resistant strain is relatively long. Allied to this, one should take into consideration that the adaptations of Status: Completed Start date: Mon Jun 01 00:00:00 GMT-03:00 2015 |
| The Cerrado is the second largest Brazilian biome and is considered one of the main biodiversity reserves on the planet that need to be conserved. For a rational and sustainable exploitation of this natural wealth, it is necessary to get to know it beforehand. A possible approach, from the point of view of the elaboration of products from Cerrado plants, is the use of aromatic species to obtain essential oils and extracts for application in the perfume and cosmetic industries. The main goal of t Status: Completed Start date: Sat Oct 01 00:00:00 GMT-03:00 2011 |

| Soil quality may be measured through the use of indicators, which are attributes that measure or reflect the environmental state or condition of sustainability of the referred ecosystem. The knowledge regarding the spatial distribution of soil quality and its levels becomes essential in this case, once it favors the study of their relation with the type of soil management, with the environmental impact and the productive capability of agricultural systems. For such, it is important to have a met Status: Completed Start date: Tue Sep 01 00:00:00 GMT-03:00 2009 |

| Some results of practical interest to soil management can be extracted from the soil's water retention curve. The recent validation of the Arya and Paris model for Brazilian soils created excellent opportunities to expand the functionality of the soil granulometric analyzer which is used to obtain in detail the entire particle distribution curve. Since the granulometric analysis takes only 20 minutes, at the same time, through the developed computing implementation, the following results can als Status: Completed Start date: Sun Apr 01 00:00:00 GMT-03:00 2007 |
| Spectroscopy, which is always associated with chemometrics, is a versatile technique that is applied in several areas of science. It is fast, non-destructive, low-cost and, in addition, “clean”, requiring few or no reagents. The latter factor aligns the tool with green chemistry.

The intense world demand for food together with environmental issues related to the sustainable use of natural resources draw a picture of search for the maximum efficiency in agricultural productivity, which involves greater efficiency in monitoring crop areas. Analytical tools capable of encompassing sample variation and territorial reach demand high costs for their operation and for the replication of results. Remote sensing has proved a very efficient tool for mapping/monitoring agricultu ...Status: Completed Start date: Thu Sep 01 00:00:00 GMT-03:00 2011 |
