“…The operational fuel consumption shows that the conventional preparation (bare soil) presented the highest consumption (21 L ha −1 ); in treatments with soil vegetation cover, specifically, brachiária and millet, the consumption levels were (16 and 15 L ha −1 ), respectively. Gozubuyuk et al [42] observed that straw cover reduced operational fuel consumption, which corroborates this research; the authors obtained liters per hour fuel savings of 3.5-fold compared to areas without vegetation cover. Conservation tillage practices, especially no-till practices, generally reduce fuel consumption, compared to conventional tillage [43].…”

“…Soybean productivity did not show a statistical difference associated with vegetation Gozubuyuk et al [42] investigated yield performance and CO 2 emissions under different sowing practices and crop rotations. They found a 137.4 kg CO 2 ha −1 reduction in CO 2 emissions from conservation tillage with vegetative soil cover, as compared to cultivation without straw, resulting in a 71.4% reduction in CO 2 emissions; these practices should be encouraged to provide fuel savings and highly environmentally friendly agricultural production.…”

Soil compaction between crop rows can increase a machine’s performance by reducing rolling resistance and fuel demand. Controlled Traffic Farm (CTF) stands out among modern techniques for increasing agricultural sustainability because the machines continuously travel along the same path in the field, reducing plant crush and compacting the soil in the traffic line. This study evaluated fuel consumption and CO2 emissions at different CTF intensities in different soil management strategies for soybean crop. The experimental design involved randomized blocks in a split-plot scheme with four replications. The plots constituted the three types of soil management: conventional tillage, no-tillage with straw millet cover, and no-tillage with brachiária straw cover. The subplots constituted for agricultural tractors were passed over in traffic lines (2, 4, and 8 times). We evaluated agricultural tractor fuel consumption, CO2 emissions, and soybean productivity. The straw cover and tractor-pass significantly affected the fuel consumption and greenhouse gas emissions of the soybean cultivation. Fuel consumption and CO2 emissions were reduced due to the machine-pass increase, regardless of soil management. Thus, a CTF reduces rolling resistance and increases crop environmental efficiency. Bare-soil areas increased by 20.8% and 27.9% with respect to fuel consumption, compared to straw-cover systems. Brachiária straw and millet reduce CO2 emissions per hectare by 20% and 28% compared to bare soil. Lower traffic intensities (two passes) showed (13.72%) higher soybean yields (of 4.04 Mg ha−1). Investigating these effects in other types of soil and mechanized operations then becomes essential.

“…No‐till crop production requires less labor and fuel (Gozubuyuk et al, 2020; Swenson & Johnson, 1982), produces fewer greenhouse gas emissions (Mangalassery et al, 2014; Six et al, 2004), and promotes soil health (Nunes et al, 2018) relative to tillage‐based crop production. However, weed management can be challenging without tillage, particularly in organic systems.…”

Cereal rye mulch biomass and crop density affect weed suppression and community assembly in no‐till planted soybean

et al. 2022

The use of multiple ecological weed management tactics may be an effective solution to weed management challenges associated with reducing tillage. An experiment was conducted to assess how soybean Glycine max (L.) Merr. density and cereal rye Secale cereale L. mulch biomass affected weed suppression and community assembly in no‐till production. Soybean was planted at five rates from 0 to 74 seeds m−2, and five cereal rye mulch levels were established from 0 to 2 times the ambient cereal rye biomass within each site–year. We assessed the effects of soybean density and cereal rye mulch biomass on weed suppression, weed community composition, and the functional structure of weed life cycle, emergence timing, seed weight, height, and specific leaf area traits. Weed suppression was influenced by a synergistic interaction between soybean density and cereal rye biomass. The functional dispersion (FDis) of all weed traits, when combined, was reduced by increased soybean density and mulch biomass, suggesting that high treatment intensities induced trait convergence. However, soybean density and cereal rye biomass had differing effects on the FDis and composition of individual traits, suggesting that these management practices represent unique filters during weed community assembly. Mulch biomass had a larger effect on annual weed suppression and weed community composition than soybean density. Farmers who utilize high biomass cover crop mulch for weed management may experience shifts in weed community composition toward an increased proportion of perennials and weeds with later emergence, heavier seeds, and shorter stature. Increasing soybean density may reduce perennial weed biomass, making it a valuable complement to high cereal rye mulch biomass. As such, weed management in no‐till soybean is enhanced by combining multiple practices, which can enable synergistic weed suppression and the management of diverse weed functional groups.

“…Reduced soil tillage or direct sowing allow inputs to be reduced and similar or even higher arable crop yields to be achieved as compared with conventional tillage. According to Gozubuyuk et al [40], after replacing conventional tillage with reduced tillage, fuel consumption was 3.5 times lower, and CO 2 emissions fell logarithmically in proportion to the reduction in soil tillage. Reduced tillage may, however, result in higher CO 2 emissions when plant residues are heavily mineralised on the soil surface [41].…”

A Strip-Till One-Pass System as a Component of Conservation Agriculture

Conservation agriculture has three main pillars, i.e., minimum tillage, permanent soil cover, and crop rotation. Covering the soil surface with plant residues and minimum mechanical soil disturbance can all result from introducing a strip-till one-pass (ST-OP) system. The aim of this study was to determine the impact of the ST-OP technology on the management of plant residues, soil properties, inputs, and emissions related to crop cultivation. We compared the effect of a ST-OP system against conventional tillage (CT) using a plough, and against reduced, non-ploughing tillage (RT). Four field experiments were conducted for evaluating the covering of soil with plant residues of the previous crop, soil loss on a slope exposed to surface soil runoff, soil structure and aggregate stability, occurrence of soil organisms and glomalin content, soil moisture and soil water reserve during plant sowing, labour and fuel inputs, and CO2 emissions. After sowing plants using ST-OP, 62.7–82.0% of plant residues remained on the soil surface, depending on the previous crop and row spacing. As compared with CT, the ST-OP system increased the stability of soil aggregates of 0.25–2.0 mm diameter by 12.7%, glomalin content by 0.08 g·kg−1, weight of earthworms five-fold, bacteria and fungi counts, and moisture content in the soil; meanwhile, it decreased soil loss by 2.57–6.36 t·ha−1 year−1, labour input by 114–152 min·ha−1, fuel consumption by 35.9–45.8 l·ha−1, and CO2 emissions by 98.7–125.9 kg·ha−1. Significant favourable changes, as compared with reduced tillage (RT), were also found with respect to the stability index of aggregates of 2.0–10.0 mm diameter, the number and weight of earthworms, as well as bacteria and fungi counts.
