Soil compaction and fertilization in soybean productivity

Abstract: Soil compaction and fertilization affect soybean development. This study evaluated the effects of soil compaction and fertilization on soybean (Glycine max cv. Embrapa 48) productivity in a Typic Haplustox under field conditions in Jaboticabal, SP, Brazil. A completely randomized design with a 5 × 2 factorial layout (compaction vs. fertilization), with four replications in each treatment, was employed. Each experimental unit (replicate) consisted of a 3.6 m 2 useful area. After the soil was prepared by cultiva… Show more

“…At the high soil density values, the grain yield (Figure 3e) was drastically reduced for all the applied soil correctives, and from soil density of 1.40 Mg m -3 , no grain yield was obtained. This result agrees with Beutler and Centurion (2004), who report a soil density of 1.37 Mg m -3 as restrictive to soybean yield. However, in the system with previous cultivation of the palisade grass (Figures 3b, 3d and 3f) a more pronounced effects of the soil correctives on the measured variables was observed, even at the highest soil density value (1.60 Mg m -3 ).…”

“…Entretanto, a modificação dos atributos depende da intensidade do tráfego a que o solo é submetido (Lima et al, 2004;Elaoud & Chehaibi, 2011). Essas alterações reduzem o suprimento de oxigênio e promovem restrições físicas ao crescimento das raízes das plantas, diminuindo o volume de solo explorado e, por consequência, podem reduzir a quantidade de água e nutrientes absorvidos, refletindo negativamente na taxa fotossintética, no crescimento e no rendimento das culturas (De Maria et al, 1999;Beutler & Centurion, 2004;Beutler et al, 2006;Fidalski et al, 2010;Costa et al, 2012;Luciano, 2012).…”

“…Em consequência, o funcionamento bioquímico da planta é modificado, restringindo, entre outros fatores, a taxa fotossintética, o crescimento da parte aérea e, com isso, o rendimento da cultura (Beutler & Centurion, 2004).…”
