“…At this point, it should be noted that the SWC did not significantly differ among the three growing seasons; therefore, we believe that the variations in the CI were not due to the SWC. Likewise, and in agreement with the findings of O'Flynn, Finnan, Curley, and McDonnell (), high soil water content makes soil susceptible to compaction when trafficking treatments are applied.…”

Sunflower (Helianthus annuus L.) harvest: Tractor and grain chaser traffic effects on soil compaction and crop yields

Previous studies have defined compaction as an important degradation process of agricultural soils. However, there is very little information (under field conditions) on the effects of tractor and grain chaser traffic during harvest operations on soil cropped for 15 years under no‐till cultivation methods. The aim of this study was to quantify the effects of two different total loads of tractor and grain chaser traffic on soil physical properties and sunflower (Helianthus annuus L.) yields. The treatments included a control plot with no tractor or grain chaser traffic (T1), a plot with tractor and grain chaser traffic with a total load of 275.8 kN (94.35 kN km−1 ha−1; T2), and a plot with tractor and grain chaser traffic with a load of 332.2 kN (123 kN km−1 ha−1; T3). Soil physical properties and sunflower yields were analysed over three growing seasons in the western part of the Pampa region, Argentina. In the topsoil (0 to 200 mm), the results showed that after one pass of T2 and T3, infiltration decreased significantly compared with that in T1; a similar trend was observed for total topsoil porosity. Cone index values in T3 were >2.5 MPa and between 3.33 and 4.90 MPa in the subsoil (200 to 600 mm). Dry bulk density values in T3 were >1.70 Mg m−3 in the topsoil and in the subsoil. This study also demonstrated that as the wheel load and ground contact pressure increase, sunflower yields decrease and subsoil compaction increases, even in soils with a high bearing capacity.

“…Overall stem yield increased somewhat in 2011 when compared with 2010 even though the trafficked zone biomass yield was significantly reduced. This occurrence was also recorded in earlier related work [9,15]. It is likely that the increased rainfall in 2011, when compared with 2010 (Table 2), coupled with the expanding rhizome mat in the establishing crop were contributing factors.…”

“…Lewandowski et al [8], and El Bassam et al [7], suggested that the Miscanthus harvest should be completed before new season growth begins. O'Flynn et al [9] added that all harvest operations should be completed before late March in northern Europe when the soil temperature reaches 10 • C (which activates new growth in the rhizomes) to prevent damage to all new growth, both underground and overground, by harvest equipment. Therefore, from this experiment Miscanthus should be harvested early, before the rhizomes have started to regrow as the magnitude of yield losses from compaction or other causes in early harvests is substantially lower than the yield losses, which can result from shoot damage in late harvest.…”

“…Alternatively, it can be cut and chipped using a forager equipped with a row independent maize header [6]. Miscanthus should be harvested annually before new shoots emerge to avoid damage by harvest equipment to the new shoots [7][8][9].…”

“…Previous work had shown that harvesting after shoot emergence can result in substantial reductions in yield and suggested that all field operations should be completed before the initiation of new growth [15]. Subsequent work had investigated the effect of annually repeated traffic from different harvesting systems on subsequent growth and productivity [9]. Both of these studies concentrated on the effect of harvest traffic after the initiation of new growth.…”

Effect of Harvest Timing and Soil Moisture Content on Compaction, Growth and Harvest Yield in a Miscanthus Cropping System

et al. 2018

Harvesting Miscanthus × giganteus (J.M. Greef & Deuter ex Hodkinson & Renvoize) after shoot emergence is known to reduce yields in subsequent seasons. This research was conducted in Miscanthus to assess the effects on crop response and soil compaction of annually repeated traffic, applied both before new growth in the rhizomes (early harvest) and after shoot emergence (late harvest), at two different soil moisture contents. While an annual early harvest, yields more than a late harvest, because damage to new shoots is avoided, soil compaction may be increased following repeated harvests. Five treatments were tested: (a) An untrafficked control, (b) early-traffic on soil with typical soil moisture content (SMC) (early-normal), (c) early-traffic on soil with elevated SMC (early-elevated), (d) late-traffic on soil with typical SMC (late-normal) and (e) late-traffic on soil with elevated SMC (late-wet). The experiment was conducted on a Gleysol in Co. Dublin, Ireland during 2010 and 2011. Crop response effects were assessed by measuring stem numbers, stem height, trafficked zone biomass yield (November) and overall stem yield (January). Compaction effects were assessed by measuring penetration resistance, bulk density and water infiltration rate. Trafficked zone biomass yield in the early-dry and early-wet treatments was, respectively, 18% and 23% lower than in the control, but was, respectively, 39% and 31% higher than in the late-dry treatment. Overall, stem yield was significantly lower in the late-normal and late-wet treatments (10.4 and 10.1 tdm ha−1 respectively) when compared with the control (12.4 tdm ha−1), but no significant difference was recorded in overall stem yield between both early-traffic treatments and the control. Penetration resistance values were significantly higher in all trafficked treatments when compared with the control at depths of 0.15 m (≥54–61%) and 0.30 m (≥27–57%) and were significantly higher in 2011 when compared with 2010 at depths of 0.15 and 0.30 m. Baler system traffic in Miscanthus significantly reduced yields and significantly increased compaction annually. Miscanthus harvested early, on a dry soil, yielded 1.1 tdm ha−1 more than when harvested late on a dry soil. The yield advantage increased to 1.3 tdm ha−1 when early harvesting on a soil with 40–43% moisture content was compared with late harvesting on a wetter soil (51–52% moisture content). In this study, the magnitude of yield losses from compaction or other causes in early harvests was substantially lower than the yield losses, which resulted from shoot damage in late harvests. It is likely in similar climates that the results of this study would also apply to other perennial crops growing in similar soil types.
