This project proposed to develop a field densitometer based on the use of Compton scattering and visualization algorithms as innovative methods to non-invasively and non-destructively measure density and compaction in agricultural soils in the environment under analysis. For the methodological evaluation, the results were compared with classical soil analysis techniques .

For the economic exploitation of animal production in pastureland, it is essential to understand the morphophysiological responses of plants and animals to environment and management conditions, so that production can be efficient. This recommendation becomes more important in intensive pasture systems. In Brazil, especially in the Southeast, Midwest, North and Northeast regions, there is a predominance of tropical forage species, characterized by high dry matter production. However, problems su

This project aimed to present reuse alternates for the waste produced in the industrial processing of açaí, and thus obtain processing plants that minimize the release of waste products. A previous evaluation of this matter pointed out technological alternatives through which would be possible to: I) reuse the residue inside or outside the processing plant, or, II) produce byproducts with aggregated value. The project proposed to develop support technologies to the açaí agroindustrial complex, w ...

GM crops that are resistant to glyphosate have created a new scenario in Brazilian agriculture. Glyphosate has been generally used mainly in soybean farms in the Brazilian states of Rio Grande do Sul, Santa Catarina and Paraná. In the state of São Paulo, glyphosate is widely used in orchards, especially citrus ones. The repeated use of glyphosate has given rise to cases of weed resistance to this herbicide in different places of the country. The trend is that new glyphosate resistant crops such ...

Embrapa Gado de Leite has the main Elephant Grass Germplasm Active Bank (BAGCE) in the country. However, the main species of grasshopper (Hemiptera: Cercopidae) and the genetic variability for resistance to these pest insects were not known. Therefore, the objective of this work was to study the population dynamics of spittlebugs and to evaluate the accessions of the elephant grass germplasm bank, regarding resistance to Mahanarva liturata. The population dynamics of cercopids in Coronel Pacheco

This research project aims to obtain information about wood harvesting, energy supply and carbon credit market using five both native and exotic forest species in experimental homogeneous and mixed plantation systems in the counties in Pará. Furthermore, as additional information, activities that open up new guidelines regarding fertilization, dissemination and phytosanitary aspects of the species in question will be carried out throughout eight actions plans. The species of interest are: paricá ...

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

Brazil annually consumes 10.5 million tons of wheat, half of which is produced in the country, which entails an approximate outlay of 800 million dollars in wheat imports. The high cost of production and the difficulties in the obtention of cultivars with technological qualities that meet market requirements are among the main limiting factors for the Brazilian wheat production chain. Out of all the cultivars available from all Brazilian breeders, about two thirds were created from germplasm

The quick diagnosis of diseases in plants that have economic value is essential to guarantee food security and avoid larger losses as a consequence of disease spreading. Two major problems may hinder this goal: 1) the permanent monitoring of all the plants by people capable of detecting diseases is mostly unviable; 2) in many cases, the person who detects the symptoms doesn't have enough knowledge to identify their causes. Despite the existance of solutions that explore technology as a facilitat
