Resistência Mecânica À Penetração Em Diferentes Sistemas De Uso Do Solo

Abstract: O objetivo deste trabalho foi avaliar a resistência do solo à penetração sob quatro diferentes sistemas de manejo do solo (café; amoreira; pastagem; silvipastoril) em três profundidades (0,0-0,20 m; 0,20-0,40 m; 0,40-0,60 m). O presente estudo foi realizado em Jardim Alegre–PR, em um Latossolo Vermelho. Os manejos foram: 1 - Cafezal cultivado manualmente; 2 - Área com amoreira para produção de bicho-da-seda, com tráfego de máquinas; 3 - Pastagem de braquiária (Urochloa decumbens) em sistema rotacionado, com ta… Show more

“…This fact is due to the greater exposure of the soil in this system causing rapid evaporation of the water, the preparation and management of the soil without organic matter supply may have caused the destruction of the aggregates and, consequently, developed a more compacted surface in the arable layer. Martins et al (2017) point out that soil use and management systems with high soil mechanical resistance to the penetration present greater compaction problems, restricting root growth and reducing water infiltration in the soil, which causes serious erosion problems (Vogel & Fey, 2016). It is worth mentioning that soil mechanical resistance to the penetration is more affected by soil moisture conditions than by density (Bartzen et al, 2019;Esteban et al, 2020), once it is inversely proportional, in other words, the higher the soil moisture the lower it tends to be in the soil mechanical resistance to the penetration.…”

“…Figura 2. Densidade de solos em diferentes usos e manejos em Candiba -Bahia A compactação é caracterizada pela alteração das propriedades físicas do solo, sendo resultado direto de uma determinada prática de manejo no qual o solo é submetido a uma determinada pressão, promovendo a redução do volume e resultando no aumento da resistência a penetração e da densidade do solo, além de prejudicar o crescimento radicular, alterar o comportamento da infiltração e escoamento das águas, podendo ocasionar erosão (VOGEL & FEY, 2016).…”
