Fine-texture soils in Brazil are generally deemed to have low agricultural potential. Due to low levels of clay and organic matter, they usually present low nutrient and water retention capacity, and, when poorly managed, may produce negative impacts associated with high risks of groundwater contamination by nutrients and other chemical pollutants, or with potential erosion when directly exposed to rain.

In order to guarantee agricultural sustainability in environments associated with t ...

A crescente demanda de água para fins industriais e residenciais, geração de energia, mineração, lazer, somados aos problemas ambientais, faz com que quantidade de água para a agricultura apresente uma tendência de redução. A agricultura é o maior usuário de água em todo o mundo. O setor agrícola brasileiro é o principal usuário consuntivo dos recursos hídricos. Uma provável solução para esse problema é aperfeiçoar como a água é manejada, o que envolve a adoção de tecnologias e procedimentos ade ...

Brazil is a tropical country with an extensive territorial area and vast plant diversity. This makes the weed species that infest the crops be widely varied. Such characteristics differentiate Brazil from other countries with temperate climates. GM crops that are resistant to herbicides, especially to glyphosate, have created a new scenario for weed control in Brazilian agriculture. Farmers have adopted RR technology right away as efficiency and cost are its main benefits. The use of glyphosate

The tomato is one of the most cultivated vegetables in the world, and is the target of countless plant health problems. Embrapa Vegetables has historically produced research in plant health within this production chain under the scope of the Tomato Genetic Improvement Project. However, the increasing demand for studies aimed at perfecting pest diagnosis methods and generating essential information for management has signaled the need to create a specific plant health project. Thus, this project

Wheat ( Triticum aestivum L.) is the world's second largest crop and Brazil has taken second place in wheat production in South America. However, productivity in this crop can be limited due to occurrence of some diseases, one of which, wheat blast, caused by the Magnaporthe grisea fungus, has caused large productivity losses that can reach 72% depending on the time of infection. With the expansion of wheat crops to other Brazilian regions such as the Midwest, the fungus has been settling in and

Brazil’s sugarcane sector plays an important role in the national economy. The country is the world’s biggest producer of sugarcane and sugar, and second in ethanol production, which contributes positively to the trade balance. In the last 15 years, the crop area has expanded tremendously, occupying so called “expansion” production areas, which differ from the traditional ones mainly in rainfall rates, leading producers to adopt irrigation. Specifically in the Northeast region, crops have migrat

Eucalyptus cropping has been growing in Brazil in the last few years and has become an important alternative for rural areas. With expressive participation in the country's trade balance, it is moved by the demand for paper, cellulose, timber and evergy. Since 2009, Embrapa Satellite Monitoring has carried out research to define efficient sustainability indicators from the assessment of tree and bush flora biodiversity and faunal biodiversity, in addition to proposing forest management actions.

Geospatial information are necessary for planning and decision making, resources management, and for the creation of public policies. Disseminating geoinformation is strategically relevant to strengthen Brazilian agriculture and to transfer the knowledge produced by Embrapa to the society. The deployment of a structure for the digital storage of spatial data and metadata enables the long-term preservation of geoinformation and its curation, manipulation and integration, thus avoiding duplicat
