Agriculture in Brazil is a means for promoting significant socioeconomic sustainable progress. However, the productivity of cereal crops such as maize, rice, wheat and sorghum is below their potential. The low availability of phosphorus (P) and inadequate fertilization are some of the major challenges of modern agriculture. In tropical soil, the phosphorus is carried out by adding high dosages of water-soluble phosphates, since most of the added fertilizer becomes unavailable because of fixat

Precision farming and agricultural practices that take into consideration the protection of the environment have brought forward a number of research challenges. The scale of sampling and the precision required by such new agricultural practices are often higher than those required by traditional agriculture, increasing production costs. Methods and devices for on-the-go measurements are being developed to equip agricultural vehicles to support these practices. The proposed project was guided

Psyllids are small sap sucking insects with generally very narrow host plant ranges. Some of them are pests that cause major economic losses in agriculture, on ornamental plants and in forestry. They damage the plants by directly removing large quantities of sap or by the transmitting diseases. The chemical control of red gum lerp psyllids in eucalypt plantations in Brazil, for instance, costs millions of reais per year due to intensive use of insecticides. Another example is the transmission of

Protein-protein interactions virtually regulate all processes inside cells, e.g. signal transduction, metabolic regulation, gene regulation, and immunological responses which occur in a specific way. Several experimental methods are capable of detecting interactions between proteins, which can range from cellular "resolution" to experiments which expose atom level interactions. However, the performance of these combined experiments which generate complete information regarding the network of pro ...

Enzymes have their function essentially determined by specific residue known as catalytic residue. Most methods to predict enzyme catalytic residue uses at least one criterion of primary sequence conservation. Considering that the function is a product of the structure, this project aims to identify among the structural descriptors available in the Sting software database those of higher relevance in the discrimination of catalytic residue. Thus, the project will propose a new enzyme classificat

This research project aims to study organic sugarcane cultivation areas of the Santo Antônio Sugar Mill in Sertãozinho, São Paulo, with emphasis on mapping and characterizing the current status of the vegetation within Permanent Preservation Areas (APPs, from the acronym in Portuguese), for the implementation of an agro-ecological project. The research project should promote an increment to the faunal biodiversity and production systems in such properties, helping the dispersion of seeds along t ...

There is pressure from society for sustainable production systems, which makes it necessary the establishment of sustainability parameters for the production systems. In this regard, animal nutrition can influence the viability and sustainability of the production system, not only by the herd feeding impact on milk production cost but also by the emission of greenhouse gases and excretion of pollutants. The basic premise of precision nutrition is the knowledge of the animal nutritional requireme
