The detection of metal ions in plant tissues is an analytical problem of biological relevance with an impact on plant production. These ions are present in the tissues of plants, and insufficient or excessive values can lead to toxicity and change in their physiology. One of the analytical strategies for the determination of metallic ions in tissues is the use of electrochemical biosensors, which allow quick, selective and sensitive responses. This project aims at the construction of a biosensor

This is a broad research project on Barbados nuts, a crop with potential to become raw material for the production of biodiesel and aviation biokerosene. In spite of its high oil production, the plant has not been totally domesticated yet, that is, there are not different recommended cultivars or production systems for each region of the country yet. In this project, which is partially funded by Finep and CNPq, there are 22 participating research institutions in all Brazilian regions, 16 of whic

What is the cost of producing one liter of milk in Brazil? Any answer between R$ 0.10 and R$ 1.70 is true. But, also, it is not essentially true. This occurs for two major reasons, both resulting from a lack of standardization. The first reason is that there is an immense amount of production systems in Brazil, from the South to the North. Therefore, in Brazil, rural properties are not standardized, as in Europe, the USA, Canada and Oceania. Each farm is a farm. The second reason is that there i

Concentrated feeds play an important role in milk production, both from the nutritional as the economic aspects, especially for animal production. The behavior of corn and soybean meal prices, for instance, have an important weight in the formation of milk production costs and consequently on the profitability of dairy farming. The current agricultural markets have shown a rise in prices of these grain-based brans. Milk production in Minas Gerais appears as one of the most important activities f

Water is an important natural resource for the competitiveness of Brazilian agriculture. Since Brazil is rich in this natural resource, to preserve it and keep it in quantity and quality is strategic. Such a competency demands water efficiency, which is the relationship between the amount of yielded products and the amount of water used for such a production. This project evaluates the performance of water indicators from milk pasture-based and confinement-based production systems and of nutriti

The TecRede project aims to generate technologies that would, in a short period of time, the development of tambaqui (Colossoma macropomum) cultivation in cage systems. The project chose the tambaqui to foment the development of cage fish farming since it is a fish native to Amapá, which has favorable domestic and international market demand, with production absorption capacity. The research network intends to determine the standardization of techniques and production systems based on Good Pr

The silvopastoral systems are a viable option to avoid degradation of pastures due to their potential to control erosion and the ability of some tree species to add nitrogen and other nutrients to the pasture, improving soil fertility. However, an important aspect in these systems refers to the competition for light between the tree/shrub and herbaceous components. Tiller production and the consequent density of inflorescences, directly related to seed production and, therefore, to natural resee

The growing competitiveness of the dairy agribusiness increasingly requires improved skills on the part of farmers. The improvement of the productive potential of dairy animals requires more efficient and balanced feeding in order to provide a real increase in production. Whether in the beef or dairy livestock segment, the Brazilian exploratory model combines herd pasture feeding with roughage supplementation in the period of food shortage, as well as energy supplementation. In such a model, the

In recent years, distance learning via the internet has become an important means of professional qualification, especially in Brazil, a country of continental dimensions. Whereas milk production is scattered throughout the national territory, distance learning offers the opportunity to bring information to professionals across the country. To this end, this project included the design, offering and accomplishment of the first distance learning courses of Embrapa Dairy Cattle, namely: "Sampling, ...

As Brazil increases its production of biodiesel, so does the production of glycerin, a by-product with a high energy value. At the same time, corn, the main energy component in concentrated feeds, in addition to being the ingredient that most increases feed costs, tends to become less available in the market due to its use in the production of alcohol in Europe and the United States. Glycerol, the main component of glycerin, has already been used in some countries, mixed with concentrate for lac
