Since the 1970s a network of underground pipes, up to 1200 mm diameter, has been installed in the UK to transmit crude oil to refineries and gas from onshore terminals for distribution. Chosen routes are subject to significant constraints. Current techniques for pipe installation involve topsoil removal and storage. Trench depth is set to allow a cover of 1200 mm overburden after pipes have been installed. The heavy machinery involved results in severe compaction of exposed subsoil. Subsoil is loosened comprehensively and topsoil replaced. Existing field drains are reconnected, and, if necessary, new drains with gravel backfill installed. Pipe installation usually takes place between April and October. Preventative measures to limit compaction during installation are not a practical option. If subsequent arable crops or grass are poorer or drainage more defective than before disturbance, the loss is assessed and compensation paid. To determine the cause of the loss >60, investigations have been made throughout the UK. Soil physical properties were assessed in an open trench using visual and tactile methods. Consistently, severe compaction in the subsoil was identified as the cause of poor crop growth or drainage; it was not observed in the topsoil. Specific recommendations for remedial action were made based on location, depth and severity of the compaction. These included the installation of additional land drains, increasing the amount of gravel above the drains, or further subsoil loosening orientated to cross gravel backfill. After appropriate remedial action, net compensation for crop losses was frequently small or negligible.

“…In our study, the NT practice modified the soil bulk density by having higher values at 20-30 and 30-40 cm layers (Table 6). This is probably the transition layer compaction described in Peigne et al (2013), which could partly explain the observation of lower primary and secondary RLDs under NT than under MP at 20-30 cm (Fig. 3).…”

Background and aims Relevant soil properties and nutrient distributions influencing crop root growth might be different under no-till (NT) and mouldboard plough (MP) management. The possible different root systems within different managements might have key impact on crop nutrient uptake and consequently crop production. Our objective was to assess the long-term combined effects of tillage and phosphorus (P) fertilization on corn (Zea mays L.) root distribution and morphology. Methods Corn root and soil samples were collected during the silking stage at five depths (0-5, 5-10, 10-20, 20-30 and 30-40 cm) and three horizontal distances perpendicular to the corn row (5, 15 and 25 cm) under MP and NT with three P fertilizations (0, 17.5, and 35 kg P ha −1 ) for a long-term (22 years) experiment in eastern Canada. Root morphology and soil properties were determined. Results NT practice decreased corn root biomass by −26 % compared to MP, mainly by decreasing the primary and secondary roots. Additionally, corn roots in NT tend to be more expansive on the surface layer with higher root length and surface densities for the depth of 0-5 cm at two sampling distances of 15 and 25 cm. The 35 kg P ha −1 rate increased the root biomass by 26 and 41 % compared to the 0 and 17.5 kg P ha −1 rates. Conclusions No-tillage practice and low rates of P fertilization reduce corn roots. This is probably caused by the weed competition in NT and the continued downward P status with low P rates over 22 years.

“…These factors can be observed, especially in the areas of Forest, Capoeira and Pasture 4, which may be related to a greater presence of organic matter in the "A horizon" and increased Ma. The use of visual methods for evaluating soil quality has been shown to be effective in reducing subjectivity, especially in assessment of soil structure, compaction, root growth, among other features (McKenzie, 2013;Muphy et al, 2013;Peigné et al, 2013). In the present work, it was possible to establish field-based soil quality indicators sensitive to levels of degraded pastures, as well as to establish a practical method for the determining the levels of degradation in field with good accuracy.…”

Developing techniques that are easily accessible to producers and extension agents would facilitate the assessment of pasture degradation in rural areas. The objective of this work was to evaluate the sensitivity of field-based indicators of soil quality at different levels of degraded pastures, validate these indicators with those determined in laboratory. Six areas were chosen: four areas of pastures in different gradients of degradation visually assessed (Degraded Pasture 1 -P 1 ; Degraded Pasture 2 -P 2 ; Degraded Pasture 3 -P 3 ; and Degraded Pasture 4 -P 4 ), in descending order of degradation; an area of Capoeira (natural vegetation of soil recovery); and a secondary Forest used as reference. The soil under all areas was an Ultisol clayey, and field determinations used were: soil coverage rate (Soil Cov. Rt ), depth of the root system (D RS ) and "A horizon" thickness. Laboratory determinations were: soil density, total porosity (Tp), macroporosity (Ma), microporosity (Mi), Ca , organic carbon (OC), base (BS) and aluminum saturation (AS). Also, the organic matter compartments such as particulate organic matter (POM), particulate organic carbon and carbon fraction associated with soil minerals were determined. Soil quality ranking were assigned to the different areas, and orthogonal contrasts were made to compare the stages of degradation. Subsequently, linear correlations were adjusted to test whether there were significant differences for the field and laboratory indicators among the areas of study. Soil quality ranking assigned represented the levels of degraded pasture visually observed in field, therefore allowing correlations with field indicators "A horizon" thickness (Rainy season r =0.71 and Dry season r =0.91) and D RS (Rainy season r =0.81 and dry season r =0.58). Similar correlations were found when the Soil Cov. Rt was used, where correlations were observed with the "A horizon" thickness (Rainy season r =0.61 and Dry season r =0.75) and D RS (Rainy season r=0.76 and Dry season r =0.84). The field and laboratory determinations showed statistical differences between study areas, indicating that they were sensitive to levels of degradation. Through field determinations, it was possible to separate four groups of degradation: reference (Forest), low degradation (P 4 and P 3 ), under recovery (Capoeira) and high degradation (P 1 and P 2 ). The easily determined field-based quality indicators showed significant correlations with the laboratory values: BS, AS, Ma and POM, especially on the 0-5 cm surface layer, showing small variation between sampling periods and indicating the possibility of using these indicators to differentiate levels of degraded pastures with good accuracy.
