Abstract 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 tractor and grain chaser traffic during harvest operations soil cropped for 15 years under no‐till cultivation methods. The aim this study was to quantify two different total loads physical properties sunflower ( Helianthus annuus L.) yields. treatments included a control plot with no or (T1), load 275.8...
Deep tillage is often performed to alleviate traffic-induced subsoil compaction, but how long do the benefits of this technique last for in intensively-managed arable soils?Heavy traffic on loose soil significantly increases risk re-compaction at depth.Chiselling and subsoiling are techniques commonly used Argentina remediate soil/subsoil compaction.Controlled farming (CTF) through exclusion heavy vehicles from field axle load reduction (e.g., ≤ 6 Mg per axle) a strategy occasionally...
<b><sc>Abstract.</sc></b> Accurate prediction of friability from soil properties that can be easily and reliably tested is important to inform practical management decisions. The water content at which the maximum different types (Inceptisol, Vertisol, Molisol, Alfisol, Ultisol) used for sugarcane production in SW Colombia was examined establish a relationship between Index soils‘ plastic limit. Friability estimated using coefficient variation tensile strength (TS) aggregates (median...

 The present work shows the effects of different agricultural wheels traffic on soil physical properties a Typic Argiudoll worked under no-tillage cropping system. Soil compaction produced by was quantified through these parameters: a) cone index, b) rut depth and c) water content at moment. Grain chaser, sprayer, harvester combine tractor equipped with commonly used in study area were tested. main results obtained showed that tyres highest inflation pressure tyre ground pressures...
<b><sc>Abstract.</sc></b> The long-term effects of zero, seasonally-controlled and ârandom‘ field traffic were monitored by measuring soil strength (used as an indicator physical quality) yield soybean over eight cropping seasons. work showed that significant yield, therefore, financial penalties may be incurred when compaction is not avoided or appropriately managed. Soil cone Index (depth range: 0-450 mm) increased in the order: zero (1.90 ± 0.31 MPa) > (2.46 0.19 random (3.75 0.21...
