“…Similarly, across four soils in the central Great Plains, NT soils retained more water at the liquid limit than CT [40]. The greater consistency limits with NT are attributed to an increased soil organic C concentration, which can provide elasticity and resistance to deformation [41]. The increased consistency with NT indicates that these soils can be trafficked when wetter than CT or RT without inducing significant compaction.…”

A long-term field experiment has been ongoing since 1999 at the Experimental Station of Vytautas Magnus University’s Agriculture Academy. According to the latest edition of the International Soil Classification System, the soil in the experimental field can be classified as Planosol, with a silty medium-loam texture at a depth of 0–20 cm and a silty light-loam texture at a depth of 20–40 cm. Studies were carried out on winter wheat crops in 2014, 2017, and 2023. This research aimed to assess how different long-term tillage systems impact soil shear strength and aggregate stability, their interconnection, and the effect of crop residues on soil stability. The treatments were arranged using a split-plot design. In a two-factor field experiment, straw was removed from one part of the experimental field, while the entire straw yield was chopped and spread at harvest in the other part (Factor A). The subplot factor (Factor B) included three different tillage systems: conventional deep ploughing, cover cropping for green manure with no tillage, and no tillage. The soil samples were analyzed at the Laboratory of Agrobiology at Vytautas Magnus University’s Agriculture Academy. The findings indicated that the long-term application of reduced tillage significantly increased the soil shear strength. Shallower tillage depths led to a higher soil shear strength, while the effect of spreading plant residues was relatively lower. The long-term tillage of different intensities, spreading plant residues, and catch crop cultivation for green manure did not significantly affect the soil structure. However, the soil structural stability was found to be highly dependent on soil tillage. Cover cropping for green manure with no tillage and no tillage alone positively affected the soil aggregate stability in the upper 0–10 cm and 10–25 cm layers. The correlation–regression analysis showed that, in the top 0–10 cm and 10–25 soil layers, there were moderate to strong correlations between the soil structural stability, soil shear strength, and the effect of crop residues on soil stability.

“…Moreover, 30 years of the undisturbed soil profile and the additional impact of heavy machinery use for field operations (planting, spraying, fertilizing, and harvesting) in the NT plots may have contributed to soil compaction (for 0-to 20-cm depth). Several researchers similarly reported that bulk density is greater in NT than in the CT field under different soil, crop pattern, and climate conditions (Blanco-Canqui et al, 2022;Jabro et al, 2021;Thomas et al, 2007;Topa et al, 2021).…”

Conservation agriculture and associated soil health practices potentially enhance soil resilience by improving the soil's physical, chemical, and biological properties and processes. This study assessed the impact of tillage (conventional tillage [CT] and no‐till [NT]); crop rotation: 2‐year corn (Zea mays L.)–soybean (Glycine max L.), 3‐year corn–soybean–oat (Avena sativa L.), and 4‐year corn–soybean–oat–wheat (Triticum aestivum L.)]; cover crops (cover crop [CC] and no cover crop [NC]); and drainage (with tile drainage [TD] and without drainage [ND]) on soil organic matter (SOM), bulk density, wet aggregate stability (WAS), and field‐saturated hydraulic conductivity (Kfs). Soil samples were collected over two years apart from five depths (0‐10, 10–20, 20–30, 30–60, and 60–90 cm) and analyzed for SOM, bulk density, and WAS. In‐situ infiltration tests were conducted in each plot to determine field‐saturated hydraulic conductivity. This study showed that NT practice significantly increased SOM by 5.4%, WAS by 7.7%, and bulk density by 6.7% within 0–10 cm soil profile but decreased Kfs by 47.6% compared to CT through increased bulk density in the topsoil. NT increased SOM for every soil depth and, similarly, increased WAS for every depth but only statistically significant increases occurred at 0–10 cm and 60–90 cm. Further, higher crop diversity decreased bulk density and increased WAS. Nine years of cover crop and six years of tile drainage practices had no significant effect on SOM, bulk density, WAS, and Kfs.This article is protected by copyright. All rights reserved

“…Soil compaction is on the surface and to a certain depth. The effect of density on soil depth and driving system factors, number of passes, soil moisture content, and soil texture significantly affect the level of soil density [11,13]. Soil density due to logging operations affects forest soil ecosystems, including forest productivity [1,35].…”

“…Each heavy equipment track tends to compact the soil and affect the macropore and organic matter [8,9,10]. The negative impacts of using heavy equipment logging operations are increasing bulk density, reducing total pore space and infiltration rate, reducing soil permeability and water holding capacity, changes in soil structure, and needing a long time IOP Publishing doi:10.1088/1755-1315/1315/1/012050 2 to be recovered [11,12,13,14]. The level of soil density is affected by the number of passes by the tractor, ground pressure of heavy equipment, tire pressure on the ground, groundwater content, and the tractor's speed [15,16,17].…”

Logging operations in natural forests generally use bulldozers. Bulldozers skid logs from the stump site to the landing site. The bulldozer maneuvers in the felling area cause skid trails and soil compaction. Soil compaction is one of the negative impacts of logging operations. The research aim is to analyze the level of soil compaction in various bulldozer skidding intensities after logging operations. The research occurred at a natural forest area in Siberut West Sumatera, Indonesia. The results of the study showed that there was a relationship between skidding intensity and the level of soil bulk density. The more a bulldozer moves at the same skid trail, the higher the soil bulk density. The range of soil bulk density is from 0.82 g cm−3 to 1.31 g cm−3. The bulk density increases markedly after the bulldozer’s first, second, and third passes. After the fourth pass, the bulk density is relatively constant. The porosity of the soil decreases with the increase of the bulk density. On skid trails where the soil is very compact, seeds that fall on skid trails will have difficulty growing well. Requires planting on primary skid trails. Soil damage in the form of soil compaction by bulldozers needs serious attention in the Reduce Impact Logging technique.
