“…The root system serves as a bridge between the impacts of tillage practices on soil and changes in shoot function and harvested yield 13,34 . Soil compaction, particularly in the subsoil layers, dramatically limits deep roots growth and development, and thus restricts the utilization of moisture and nutrients by the plants in the subsoil 17 . Suitable tillage practices could improve the soil structure by loosening the soil and reversing soil compaction in deeper soil layers, thus, resulting in an improved root system, which is the most critical role that tillage plays in the soil-plant systems 18 .…”

“…Low moisture and nutrient absorption capacity of roots in the compacted soil limits the elongation capacity of roots, which is completely curbed at the soil strength of 2MPa 15 . Increased root penetration and reduced movement of water in the soil reduces the water and nutrient availability to crops and changes the distribution of roots between soil layers and may confine root development to the upper part of the soil profile, which restricts plant availability to water and minerals 16,17 . Therefore, increased soil compaction has recently been identified as the primary limiting factor in root growth and uptake of moisture and nutrients.…”

Excessive tillage and soil compaction threaten the sustainable farmlands in the Huang-Huai-Hai Plains of China. Our study explores tillage practices to improve soil and root ecology and promote productivity in the winter wheat fields. We tested the impact of plowing, rotary, strip rotary tillage and strip rotary tillage with a two-year subsoiling interval (SRS) on wheat yield and root quality. SRS decreased soil bulk density compared with other treatments, resulting in lower soil penetration resistance. Root morphology and weight density decreased with the increased soil depth and was higher in SRS. Moreover, SRS increased the indoleacetic acid and trans zeatin riboside levels corresponding to greater TTC reduction activities, the total and active absorption root area. SRS increased the superoxide dismutase and catalase activities and soluble protein concentration and decreased the malondialdehyde concentration. The first two factors extracted using 11 root attributes in various soil layers through principal component analysis were selected as the integrated indicators for the minimum data set, and their integrated score was calculated to quantify the root quality. Our study suggests that SRS could significantly improve root morphology and enhance the root activity in subsoil layers, thus, delaying root senescence and increasing winter wheat yield.

“…When compared to the conventional system, no-till had soil densities relatively lower. This difference can be attributed to the OM accumulation in notill areas, resulting in longer reductions in soil compaction and increases in soil aggregation (Guaman et al, 2016). TABLE 2.…”

“…In the Brazilian Cerrado, Oxisols have shown some problems related to improper management practices, as these soils are highly susceptible to compaction under natural conditions, mainly by machinery traffic during rainy season (Severiano et al, 2011). The effects of heavy traffic compaction may persist for more than a decade and are especially unfavorable in highly moist soils (Guaman et al, 2016, Holthusen et al, 2018.…”

Soil compaction in agricultural areas has greatly increased in recent decades due to intensive farming practices, including short-cycle crops and machinery intensification. This study aimed to evaluate the impacts of management systems on the physical quality of a dystrophic Yellow Oxisol, in the Cerrado region of Brazil. Treatments consisted of five soil management systems, with five replications (native forest [control], slash-andburn agriculture, pasture, no-tillage, and conventional tillage). Data analysis was performed using a completely randomized experimental design. All systems were analyzed for soil density, macroporosity, microporosity, total porosity, hydraulic conductivity, infiltration, water retention curve, penetration resistance, and soil quality index (S index). The systems had significant effects on soil structure, and the evaluated properties responded well to changes promoted by them. No-tillage implementation raised soil resistance in the area previously damaged by intensive farming. Moreover, soils under pasture and slash-and-burn systems presented higher water retention in field capacity and higher S indexes, thus having a better structural quality.

“…With the compaction, there is the increase of the mechanical resistance of the soil and the reduction of porosity, pore continuity, permeability and availability of nutrients and water are reduced, reducing the root growth and development of the cultivation (Streck et al, 2004;Guaman et al, 2016;Beriso et al, 2012).…”

Corn (Zea mays L.) is one of the most cultivated grains in the world. It provides widely used products such as food, feed, raw materials for industry and ethanol, mainly due to the quantity and nature of its reserves accumulated in the grains. The objective of this research was to evaluate different depths of sowing and the use of different initial methods of soil preparation for growing corn. A randomized-complete blocks design was applied in a split plot with subsoiling, tillage, rotary hoe, ploughing, manual weeding and three sowing depths. Analysis of variance showed a significant difference (p < 0.01) of stem diameter (SD), plant height (PH), root fresh mass (RFM), root dry mass (RDM), aerial dry mass (ADM), aerial fresh mass (AFM), while number of leaves (NL) showed no differences statistically. Regarding to stem diameter, the methods with subsoiling, ploughing and rotating hoe showed the best results. In relation to plant height, the treatments of subsoiling, tillage, ploughing and rotating hoe had the best performances. The use of the subsoiling method showed the best results between the characteristics of the plant and corn yield. The corn yield presented better yields with the subsoiled and rotary hoe preparation.
