Resumo: | The effects of the injection of liquid bovine waste (DLB) on the soil combined with the use of nitrification inhibitors, such as dicyanodiamide (DCD), is still poorly documented, mainly on N losses to the atmosphere via N-NH3 emission, (EUN), plant parameters and wheat and maize productivity in subtropical southern Brazil. Thus, the objective of the present work was to evaluate how the DLB application in the soil in notillage system (SPD) affects the ammonia emission (N-NH3) of the DLB in the system, as well as this practice Combined with DCD can affect EUN, plant parameters and wheat and maize yield. Four studies were conducted in the field at two distinct sites belonging to the Federal University of Santa Maria, one in Frederico Westphalen, RS, in a dystrophic Red Latosol, and the other in Santa Maria, RS, in an Alumínico (DLBs), DLBs + DCD, injected DLB (DLBi), DLBi + DCD, control and mineral fertilization (NPK) on the surface. The studies were conducted simultaneously at both sites. The application of DLB was performed manually with irrigators, while the injection was mechanized, at depth of 8-11 cm. The DCD dose used was 7 kg ha-1, mixed to the DLB instants before application to the soil. Compared to surface application, DLB injection in the soil proved to be efficient in reducing N-NH3 emissions to the atmosphere, both in wheat and maize. The efficiency of the injection was maximized when combined with DCD, increasing N-NH4 + retention in the system, also increased apparent N recovery (103%), N agronomic efficiency applied with DLBs and crop productivity compared to N Surface application. The best performance of the crops occurred in the treatment with DLB + DCD injection (DLBi + DCD). In addition, this practice was efficient in reducing N losses by volatilization of ammonia (N-NH3), guaranteeing greater N availability at Plants. In view of these results, the injection of DLB + DCD in soil in SPD is a promising alternative to soil surface application, as well as EUN, productivity and plant parameters in wheat and corn as well as beneficial In the reduction of N-NH3 emission. |

Assim, o objetivo do trabalho foi avaliar como o modo de aplicação (injeção x superficial) do DLB no solo em sistema de plantio direto (SPD) afeta a emissão de amônia (N-NH3), bem como esta prática combinada com DCD pode afetar a EUN, parâmetros de planta e a produtividade de trigo e milho. Quatro estudos foram conduzidos simultaneamente a campo em dois locais distintos pertencentes à Universidade Federal de Santa Maria, um em Frederico Westphalen, RS, num Latossolo Vermelho Distrófico típico, e o outro em Santa Maria, RS, em um Argissolo Vermelho Alumínico úmbrico, no delineamento experimental de blocos ao acaso com quatro repetições dos seguintes tratamentos: DLB aplicados na superfície do solo (DLBs), DLBs+ DCD, DLB injetados (DLBi), DLBi + DCD, testemunha e adubação mineral (NPK) em superfície. A aplicação dos DLB foi realizada de forma manual com regadores, enquanto a injeção foi mecanizada, na profundidade de 8-11 cm. A dose de DCD utilizada foi de 7 kg ha-1, misturada aos DLB instantes antes da aplicação no solo. A injeção dos DLB no solo mostrou-se eficiente na redução de emissões de N-NH3 para a atmosfera, tanto no trigo, como no milho. A eficiência da injeção foi maximizada quando combinada com DCD, aumentando a retenção de N-NH4 + no solo e a recuperação aparente de N (103%), a eficiência agronômica do N aplicado com os DLB e a produtividade das culturas em comparação à aplicação superficial. O melhor desempenho das culturas ocorreu no tratamento com a injeção (DLBi + DCD), garantindo maior disponibilidade de N às plantas. Diante desses resultados, a injeção dos dejetos líquidos de bovinos mais a dicianodiamida no solo em SPD, constitui uma alternativa de manejo promissora, em relação à aplicação na superfície do solo, quanto a EUN, produtividade e parâmetros de planta no trigo e milho bem como na redução de emissão de N-NH3.Universidade Federal de Santa MariaBrasilAgronomiaUFSMPrograma de Pós-Graduação em Agronomia - Agricultura e AmbienteUFSM Frederico WestphalenBasso, Claudir Joséhttp://lattes.cnpq.br/6844653805754593Fiorin, Jackson Ernanihttp://lattes.cnpq.br/6845721050199588Pujol, Stefen Barbosahttp://lattes.cnpq.br/5611615203052456Silva, Alieze Nascimento da2017-09-06T12:55:22Z2017-09-06T12:55:22Z2017-02-21info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://repositorio.ufsm.br/handle/1/11621porAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSM2022-08-15T10:55:30Zoai:repositorio.ufsm.br:1/11621Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2022-08-15T10:55:30Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
