Is chiseling or inverting tillage required to improve mechanical and hydraulic properties of sandy clay loam soil under long-term no-tillage?

Soil Mechanical Resistance Penetration after Fifteen Years with Previous Crops and Tillage Systems and Productivity of Green Corn Cob in Northeast Brazil

“…However, the crotalaria culture was the one that contributed with lower MRP values along the profile, concluding that its root system developed in better condition. This was probably due to the roots of the pivotal type, which provide the presence of biological pores, decomposition of the same associated to the non-revolving soil, as reported Reinert, et al [27]. According to Schmidt, et al [17] the conservationist systems provided increased soil fertility, especially in relation to the exchangeable bases and soil organic matter content, motivated by legume species that favored increases.…”

Is cassava yield affected by inverting tillage, chiseling or additional compaction of no-till sandy-loam soil?

“…Higher soil Bd observed in subsurface layers in all the soil tillage methods compared to surface layer could occur due to natural densification and traffic effect of farm machinery used for tillage operations and no-till pan in NT soil (Reichert et al, 2009a). The high Bd in all treatments at cassava physiological maturity was expected, and is attributed to soil reconsolidation after tillage (Reichert et al, 2016a(Reichert et al, , 2017. Means followed by the same letters in a given row are not different using Least Significant Difference (LSD) at 5 % probability level.…”

“…Conventional tillage, the traditional tillage method used for cassava (Santos et al, 2020;Thomaz and Fidalski, 2020), is another option for decreasing soil compaction, but the excessive disturbance from soil inverting and mixing by plowing and disking causes undesirable effects such as soil disaggregation, with further exposion to rainfall impact (Lima et al, 2015), especially in sandy soils that are highly prone to erosion (Cantalice et al, 2005;Silva et al, 2020;Thomaz and Fidalski, 2020). In Brazil and elsewhere, the different tillage methods have been evaluated for soil compaction by quantifying the limiting soil bulk density and the performance of several crops (Suzuki et al, 2007;Reinert et al, 2008;Reichert et al, 2009a;Secco et al, 2009;Suzuki et al, 2013;Mentges et al, 2016;Moraes et al, 2019;Reichert et al, 2016aReichert et al, , 2017Reichert et al, , 2018Ambus et al, 2018;Andognini et al, 2020;Reichert et al, 2021a,b).…”

Best tillage practices for eucalyptus growth and productivity: A review on the Brazilian experience

“…Generally, porosity reduction occurs with a reduction in larger pores, responsible for water infiltration and soil aeration, followed by an increase in the number of smaller pores (Reichert et al, 2007(Reichert et al, , 2014. Machine traffic and no-tillage can reduce the volume of larger pores and increase the smaller ones, while tillage can promote the opposite behavior (Reichert et al, 2017a). Therefore,…”
