Resumo: | Soil compaction occurs due to the disorderly passages of machines verified in traditional traffic. Matching traffic lines, working width and gauge of agricultural machinery allow the adoption of controlled traffic farming. This type of traffic aims to concentrate the compaction in the same places in all agricultural activities, seeking to keep the places without traffic in favorable conditions to the development of plants. The objective of this study was to analyze: physical attributes of a typic Hapludox soil, root system length, and soybean and oat yields, subjected to different types of agricultural traffic under a no-tillage system (NT). The study was conducted in a 89 ha field (on-farm research), in the municipality of Carazinho, RS, managed under NT over the last 20 years. Two sources of variation were investigated, traffic types and intensities. For traffic types the levels were: traditional traffic (TT), controlled traffic (CTF) and annual alternate traffic (AAT). For traffic intensities the levels were: maximum traffic (Tma), maximum traffic one year ago (Tma1), maximum traffic two years ago (Tma2), medium traffic (Tme), medium traffic one year ago (Tme1), medium traffic two years ago (Tme2) and without traffic (WT). This study firstly presented changes in the soil physicohydraulic parameters and its association with and soybean seed yield and oat aboveground dry mass production (ADMP). Evaluations were performed for soil bulk density, macroporosity, microporosity, total porosity at four times; penetration resistance at seven times; soil water infiltration rate at twice. Soybean seed yield was evaluated during three growing seasons, from 2015 to 2018, and oat ADMP in 2017. As a second section, it was explored the relationship between the traffic intensities, root development and soybean seed yield in the 2017/18 growing season. Lastly, the results of the first and second studies were standardized to a hectare base, and they were evaluated dependently for each type of traffic, as well as the profitability and payback. In the first study were observed, soil bulk density reductions and macroporosity increases in the soil surface. The accumulated infiltration increased in the places without traffic for CTF and AAT treatments. Soybean seed yield in the 2016/17 growing season increased in the treatments WT, Tme1 and Tma1. The most productive ADMP oat treatments was AAT WT. In the second study the effect of the shanks under the old traffic lines was temporary, not being perceived after two years of the displacement of the traffic lines. There was no significant difference for root length and for soybean seed yield. For the third study was verified an increase in the accumulated yield for the CTF and AAT traffics, while the highest profitability and the shortest time for the payback was observed in the CTF treatment. Thus, it was verified that AAT should be evaluated for a longer period in order to determine the beneficial of performing traffic lines planned changes in the soil. In summary. The adoption of CTF provided improvements in the physical structure of the soil, increased the accumulated infiltration and the profitability promoting a productive increment. |

O planejamento das linhas de tráfego e ajustes de largura de trabalho e bitola de máquinas agrícolas permitem a adoção do tráfego controlado. Esse tipo de tráfego visa concentrar a compactação nos mesmos locais em todas as atividades agrícolas, buscando manter os locais sem tráfego em condições favoráveis ao desenvolvimento das plantas. O objetivo desse trabalho foi analisar os atributos físicos de um Latossolo Vermelho Distrófico típico, o comprimento do sistema radicular e produtividade das culturas soja e aveia submetidas a diferentes tipos de tráfego agrícola sob plantio direto (PD). O estudo foi conduzido em uma área comercial de 89 ha no município de Carazinho, RS, manejada sob PD por aproximadamente 20 anos. Os tratamentos foram constituídos pelos tipos de tráfego: tradicional (TT), controlado (TC) e alternado anual (TAA). Para intensidades de tráfego os seguintes tratamentos foram adotados: máximo (Tma), máximo há um ano (Tma1), máximo há dois anos (Tma2), médio (Tme), médio há um ano (Tme1), médio há dois anos (Tme2) e sem tráfego (ST). Este estudo apresenta na primeira parte, as alterações nas propriedades físico-hídricas do solo e produtividade da cultura da soja e aveia. Foram avaliados a densidade (DS), macroporosidade (Macro), microporosidade (Micro), porosidade total (PT) em 4 épocas, resistência a penetração do solo (RP) em 7 épocas, taxa de infiltração de água no solo em 2 épocas, 3 safras de soja e 1 de aveia, entre 2015 e 2018. Na segunda parte do trabalho, foi analisada a relação das intensidades de tráfego com o desenvolvimento radicular e produtividade da cultura da soja na safra 2017/18. No terceiro trabalho os resultados do primeiro e segundo trabalhos foram relativizados para hectare, e avaliados para cada tipo de tráfego, bem como a lucratividade e o retorno econômico. No primeiro estudo foram constatados redução da DS e aumento da Macro na superfície do solo, a infiltração acumulada foi incrementada nos locais sem tráfego dos tratamentos TC e TAA. A produtividade da soja safra 2016/17 foi incrementada na nos tratamentos ST, Tme1 e Tma1, para a aveia o tratamento mais produtivo foi TAA ST. No segundo estudo o efeito dos sulcadores sob as antigas linhas de tráfego foi temporário, não sendo percebido após dois anos do deslocamento das linhas de tráfego. Não houve diferença significativa para os resultados de comprimento radicular, ocorrendo o mesmo para produtividade de soja. Para o terceiro estudo foi verificado o incremento produtivo acumulado para os tráfegos TC e TAA, bem como a maior rentabilidade e o menor tempo para o retorno do investimento no tratamento TC. Assim, verifica-se que TAA deve ser avaliado por período mais longo a fim de determinar o quão benéfico é ao solo as mudanças planejadas das linhas de tráfego. E conclui-se que a adoção do TC proporciona melhoras na estrutura física do solo, aumenta a infiltração acumulada e propicia lucratividade e incremento produtivo.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPESporUniversidade Federal de Santa MariaCentro de Ciências RuraisPrograma de Pós-Graduação em Ciência do SoloUFSMBrasilAgronomiaAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessCompactação do soloTráfego tradicionalTráfego alternado anualDeslocamento de linhas de tráfegoDistribuição vertical de raízesSoil compactionTraditional trafficAnnual alternate trafficDisplacement of traffic linesVertical distribution of rootsCNPQ::CIENCIAS AGRARIAS::AGRONOMIAAtributos físicos de um latossolo, sistema radicular e produtividade da soja sob tráfego controlado em plantio direto no sul do BrasilPhysical attributes of a typic hapludox, root system and soybean seed yield under controlled traffic farming in no-tillage system in southern Brazilinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisAmado, Telmo Jorge Carneirohttp://lattes.cnpq.br/8591926237097756Bottega, Eduardo Leonelhttp://lattes.cnpq.br/2754758384879917Reimche, Geovane Boschmannhttp://lattes.cnpq.br/8140181961367166Leal, Otávio dos Anjoshttp://lattes.cnpq.br/0948894948879689Girardello, Vitor Caudurohttp://lattes.cnpq.br/6887813887204675http://lattes.cnpq.br/5845107143278911Teixeira, Tiago De Gregori5001000000096008744c75f-e323-495a-80de-7684a957d85e697e81d2-79cb-4e1f-b80b-70c83be0aea75005d1f4-4b91-4e32-960f-de8b7053bdc76916fd40-e8bd-44a8-b121-5305a8cacb2dacbfbd50-5df0-48e7-9567-133f455fb39185497bf1-02fa-48c0-9e8e-2c7c94c0eb2breponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALTES_PPGCS_2018_TEIXEIRA_TIAGO.pdfTES_PPGCS_2018_TEIXEIRA_TIAGO.pdfTese de Doutoradoapplication/pdf5909937http://repositorio.ufsm.br/bitstream/1/16308/1/TES_PPGCS_2018_TEIXEIRA_TIAGO.pdfaacd94bdbcb5ff2926d268d10ded1eafMD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;

Soil compaction occurs due to the disorderly passages of machines verified in traditional traffic. Matching traffic lines, working width and gauge of agricultural machinery allow the adoption of controlled traffic farming. This type of traffic aims to concentrate the compaction in the same places in all agricultural activities, seeking to keep the places without traffic in favorable conditions to the development of plants. The objective of this study was to analyze: physical attributes of a typic Hapludox soil, root system length, and soybean and oat yields, subjected to different types of agricultural traffic under a no-tillage system (NT). The study was conducted in a 89 ha field (on-farm research), in the municipality of Carazinho, RS, managed under NT over the last 20 years. Two sources of variation were investigated, traffic types and intensities. For traffic types the levels were: traditional traffic (TT), controlled traffic (CTF) and annual alternate traffic (AAT). For traffic intensities the levels were: maximum traffic (Tma), maximum traffic one year ago (Tma1), maximum traffic two years ago (Tma2), medium traffic (Tme), medium traffic one year ago (Tme1), medium traffic two years ago (Tme2) and without traffic (WT). This study firstly presented changes in the soil physicohydraulic parameters and its association with and soybean seed yield and oat aboveground dry mass production (ADMP). Evaluations were performed for soil bulk density, macroporosity, microporosity, total porosity at four times; penetration resistance at seven times; soil water infiltration rate at twice. Soybean seed yield was evaluated during three growing seasons, from 2015 to 2018, and oat ADMP in 2017. As a second section, it was explored the relationship between the traffic intensities, root development and soybean seed yield in the 2017/18 growing season. Lastly, the results of the first and second studies were standardized to a hectare base, and they were evaluated dependently for each type of traffic, as well as the profitability and payback. In the first study were observed, soil bulk density reductions and macroporosity increases in the soil surface. The accumulated infiltration increased in the places without traffic for CTF and AAT treatments. Soybean seed yield in the 2016/17 growing season increased in the treatments WT, Tme1 and Tma1. The most productive ADMP oat treatments was AAT WT. In the second study the effect of the shanks under the old traffic lines was temporary, not being perceived after two years of the displacement of the traffic lines. There was no significant difference for root length and for soybean seed yield. For the third study was verified an increase in the accumulated yield for the CTF and AAT traffics, while the highest profitability and the shortest time for the payback was observed in the CTF treatment. Thus, it was verified that AAT should be evaluated for a longer period in order to determine the beneficial of performing traffic lines planned changes in the soil. In summary. The adoption of CTF provided improvements in the physical structure of the soil, increased the accumulated infiltration and the profitability promoting a productive increment. |
