“…In addition, the mechanized sowing of annual crops promotes spatial variation in the soil's physical properties under no tillage, in which the furrow-opening mechanism causes some decompression in the sowing furrow [18]. This factor, coupled with planting fertilizer also in the sowing furrow and continuous water replenishment due to the occurrence of well-distributed rainfall, may be the reason why the crop has shown productive stability in all the systems evaluated.…”

“…Compaction is a consequence of the compression of unsaturated soil when subjected to the pressures applied by machinery and animals [15,16] and is characterized as the greatest physical limitation to high crop productivity worldwide [17,18]. For this reason, the recovery of the soil's physical quality is of agricultural and environmental importance, especially in tropical regions, such as the Latossolos in Cerrrado [in the Brazilian Soil Classification System-Santos et al [19]; Oxisols in the USA Keys of Soil Taxonomy-Soil Survey Staff (2014); and Ferralsols in the World Reference Base for Soil Resources-IUSS Working Group WRB (2015)], in soils that are highly susceptible to compaction [13].…”

Soybean is one of the most widely grown crops in the world and technologies are increasingly needed to increase productivity without impacting environmental degradation. In this context, the aim was to evaluate the action of forage plants of the genus Brachiaria sp. in crop–livestock integration on physical soil, agronomic and environmental aspects of soybean cultivation. The experiment was conducted in a subdivided plot design with seven integrated systems corresponding to the previous cultivation of Paiaguas palisadegrass, Xaraes palisadegrass and Ruziziensis grass in monocropping and intercropped with maize, as well as maize in monocropping. In the subplots, two grass management systems were evaluated: free growth and a grazing simulation cut. The bulk density and least limiting water range were assessed using soil samples and, after the pastures were desiccated when the soybean crop was planted, straw decomposition and plantability. A soil physics diagnosis by the bulk density and least limiting water range showed that the Paiaguas palisadegrass and Xaraes palisadegrass improved the soil environment due to biological soil loosening. The remaining mulch biomass did not affect soybean sowing and the adoption of Brachiaria sp. grass in the off-season, in addition to contributing to the provision of environmental services, and did not compromise grain productivity in succession.

“…The opener is required to cut through the soil easily, without disturbing the soil layers and with low working resistance [10]. Researchers have designed a variety of openers based on agronomic requirements and field soil characteristics [11][12][13][14]. Among them, the double-disk opener has been widely used in precision planters, and has the advantages of stable operation performance, neat groove shape and small soil disturbance [15,16].…”

The traditional gauge wheel has poor performance in reducing the adhesion to soil and constructing seed furrow, which results in lower seeding quality of the planter. To reduce the adhesion of the gauge wheel to the soil and build a well-structured seed furrow, an elastic gauge wheel with soil retention groove and irregular cavity was designed in this study. The soil retention groove built ridges on both sides of the seed furrow and avoided the gauge wheel compacting the seed furrow sidewalls. The irregular cavity increased the elasticity of the gauge wheel and allowed the wheel to squeeze the soil on both sides of the seed furrow, which reduced the soil adhesion of the wheel and built stable ridges. Soil moisture content was chosen as the experimental factor for comparative tests to evaluate the soil adhesion and the constructed seed furrow of the gauge wheel with an irregular cavity and the traditional gauge wheel. The experimental results showed that the viscosity reduction rate of the gauge wheel with the irregular cavity was not less than 12.61%. Compared with the traditional gauge wheel, the seed furrow constructed by the irregular cavity gauge wheel had ridges on both sides and less backfill soil, and the soil compaction of sidewalls decreased by 18.16%. The field experiment was designed using the Box–Behnken design. The working speed, downforce, and planting depth were taken as experimental factors, and the soil adhesion of the gauge wheel and the consistency of planting depth were taken as evaluation indicators. The optimal operating parameters of planter obtained by Design-Expert 8.0.6 software were as follows: the working speed was 8 km·h−1, the downforce was 844 N, and the planting depth was 65 mm. The verification test of the optimal operating parameters showed that the soil adhesion mass of the gauge wheel was 123.65 g and the coefficient of variation of the planting depth was 5.35%. This study provides a reference for the mechanized construction method of seed furrow by precision planter and the structural design and performance optimization of gauge wheels.
