Força de tração e mobilização do solo por hastes sulcadoras de semadoras-adubadoras

Abstract: RESUMOO desempenho de semeadoras-adubadoras pode ser influenciado pelos resíduos culturais sobre o solo em áreas com semeadura direta. Neste sistema, a utilização de hastes sulcadoras para distribuição de adubo pode minimizar possíveis zonas de compactação. O objetivo do trabalho foi avaliar o efeito das variáveis doses de resíduos de culturas de inverno uniformemente distribuídos no solo, profundidades de atuação do sulcador de adubo e número de linhas da semeadora sobre a demanda de tração medida nas hastes,… Show more

“…Since the shank is at a greater depth, the tractor will need more power to disrupt a larger mobilized soil area, according to the results in Table 2. These results are similar to those obtained by Cepik et al (2010) who worked with two seeders, one with three lines and the other with five lines, and observed higher requirement of tractor power at the greatest depths.…”

“…The operation in subsurface using plow shanks influences the need for increasing demand of power and the increase in tractor slippage, requiring more traction power to work at greater depths (Cepik et al, 2010). Conte et al (2009), studying shanks at depths of 0.064 and 0.12 m, also observed higher requirement of power when the plow shanks were used at the greatest depth; however, these authors claim that there is a beneficial effect to combat the water stress caused by the increase in root growth through the breaking of compacted layers, which would contribute to the maintenance of soybean production under water scarcity conditions.…”

“…However, because of direct seeding systems, seed drills had their manufacturing process changed, making them robust, heavy and with soil-engaging components capable of breaking compacted soil layers caused by equipment traffic on the field, and hence newer seeders require tractors to have more traction power to pull them. Cepik et al (2010) discuss that farmers should consider the use of shank-type furrow openers for fertilizer application in compacted soils or compaction-prone areas. In direct seeding, nutrients tend to concentrate on the soil surface.…”

“…Consequentemente, um dos fatores que contribuem para o sucesso da semeadura direta é a seleção e utilização correta desses equipamentos, pois seu desempenho é afetado pela presença de resíduos culturais sobre o solo [7] e pelas condições de solo impostas [8][9], sendo que a escolha adequada resulta do ajuste do planejamento da produção da propriedade, obtendo-se a máxima eficiência operacional e a capacidade efetiva de trabalho, reduzindo custos.…”
