The changes in climate behavior will probably bring changes to the hydrological cycle. As a result, these variations will probably affect crop development, crop production, and water consumption.
Therefore, the project’s proposal is to determine the water requirement for irrigation in the current weather and in different future climate scenarios for the cropping of pineapple and coconut in the North, and orange, in the Northwest of the state of Rio de Janeiro, Brazil, since those are the cro ...

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

Low productivity of pastures in Brazil is the main cause of poor profitability and competitiveness of animal production systems in relation to other agricultural systems. The objective of the project was to generate technologies in intensive system of livestock grazing using Tanzania grass ( Panicum maximum), Marandu palisadegrass ( Brachiaria brizantha) and Star grass ( Cynodon nlemfuensis) to improve forage production and quality and milk production. To this end, evaluatio ...

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

Sustainability of traditional cultivation systems (slash-and-burn) depends especially on long periods of set-aside in order to reestablish the stock of the soil's nutrients and raw organic material used and/or lost during the agricultural period. Population growth and decrease in the region's secondary vegetation availability has progressively reduced the set-aside period, subsequently increasing the pressure on riparian areas and cultivated ones. The result if degradation of natural resources a

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 ...
