Emissão de amônia e dinâmica do nitrogênio no solo com parcelamento da dose e adição de inibidor de nitrificação em dejetos de suínos
(Universidade Federal de Santa Maria, 2012-04-27)
Pig Slurry (PS) is used mainly as a fertilizer for crops in southern Brazil where the
predominant soil management is in no-tillage. Thus, the application of manure on the soil
surface can increase losses of nitrogen (N) ...
Acúmulo de carbono no solo e potencial de aquecimento global influenciados pelo modo de aplicação de dejetos líquidos de suínos e inibidor de nitrificação
(Universidade Federal de Santa Maria, 2016-07-04)
Studies about the effect of pig slurry (PS) injection in the soil and the use of nitrification inhibitors, such as dicyandiamide (DCD), have been focused on the dynamics of nitrogen in the soil-plant-atmosphere system. The ...
Acidificação de dejetos de suínos em compostagem automatizada: emissões gasosas de nitrogênio e resposta da alface à aplicação do composto no solo
(Universidade Federal de Santa Maria, 2014-08-29)
Automated pig slurry (PS) composting has been praised in Brazil by environmental agencies, pig farmers and agribusinesses as a promising strategy for the proper disposal of these residues. Nevertheless, one of the problems ...
Avaliação e modelização da dinâmica de carbono e nitrogênio em solo com o uso de dejetos de suínos
(Universidade Federal de Santa Maria, 2005-02-28)
The managedment of the pig manure, in the slurry or solid form (deep bedding), and how it is applied to the soil, in the surface or incorporated, must affect the dynamics of the C and the N in the soil. The objectives of ...
Eficiência de uso do nitrogênio por gramíneas em função do modo de aplicação de dejetos suínos no solo e do uso de inibidor de nitrificação
(Universidade Federal de Santa Maria, 2016-04-01)
The effect of pig slurry (PS) injection into the soil and nitrification inhibitor use such as dicyandiamide (DCD) on gaseous N losses to the atmosphere is better documented than the effect of these practices on nitrogen ...
Dinâmica do nitrogênio sob sistema plantio direto e parâmetros para o manejo da adubação nitrogenada no milho
(Universidade Federal de Santa Maria, 2009-03-27)
Among the several essential nutrients in the nutrition of the maize, without a doubt, the nitrogen (N) is one of the most important. However, most of the time, the amount naturally available in the soil is insufficient ...
Dinâmica do carbono em latossolo vermelho sob sistemas de preparo de solo e de culturas
(Universidade Federal de Santa Maria, 2006-04-27)
The soil C stock is a consequence of the balance between the C losses by the CO2 emission (associate to the heterotrofic microorganisms activity) and erosion, and to C inputs, associate to organic compounds input by the ...
Ciclagem de nutrientes e produtividade de grãos em sucessões de culturas sob sistema plantio direto
(Universidade Federal de Santa Maria, 2008-06-27)
The no-tillage adoption combined with the presence of crop residues on soil surface and minimum soil disturbance increase the soil organic matter content, that
associated with broadcast fertilization, change the nutrient ...
Fertilização nitrogenada à dose variada na cultura do milho
(Universidade Federal de Santa Maria, 2014-02-25)
Maize is the main cereal produced in Brazil, being highly responsive to nitrogen fertilization, since the tropical and subtropical soils presents insufficient availability of nitrogen (N) to attend the culture demand in ...
Distribuição espacial de plantas na fileira e sua relação com a produtividade da cultura do milho
(Universidade Federal de Santa Maria, 2015-01-12)
Decreased variability in the distribution of plants on line and increased nitrogen fertilization efficiency are important order management for high yields in corn. The objective of this study was to evaluate the quality ...
