“…Soil water pressure data was used to estimate the effective pore size using the capillary rise equation (Jury et al 1991). Pore sizes were divided into four different classes: macropores (>1,000 μm [>0.039 in] effective diameter), coarse mesopores (60 to 1,000 μm [0.0024 to 0.039 in] effective diameter), fine mesopores (10 to 60 μm [0.00039 to 0.0024 in] effective diameter), and micropores (<10 μm [<0.00039 in] effective diameter) as were used in Rachman et al 2004.…”

“…They also concluded that after six years of establishing the buffers, soil under buffers can store more water and hence would have lower runoff and less sediment, nutrient, and herbicide losses. Similarly, Rachman et al (2004) showed that areas under perennial grass hedges for more than ten years had lower bulk density and clay content and higher porosity and saturated hydraulic conductivity than areas under row crop cultivation for the same soil. Skaggs et al (2006) studied the effects of forest management on saturated hydraulic conductivity (K sat ) and found K sat values for a mature plantation forest were 20 to 30 times higher than values given in the soil survey for the study area.…”

Various land management decisions are based on local soil properties. These soil properties include average values from soil characterization for each soil series. In reality, these properties might be variable due to substantially different management, even for similar soil series. This study was conducted to test the hypothesis that for claypan soils, hydraulic properties can be significantly affected by long-term soil and crop management. Sampling was conducted during the summer of 2008 from two fields with Mexico silt loam (Vertic Epiaqualfs). One field has been under continuous row crop cultivation for over 100 years (Field), while the other field is a native prairie that has never been tilled (Tucker Prairie). Soil cores (76 × 76 mm [3.0 × 3.0 in]) from six replicate locations from each field were sampled to a 60 cm (24 in) depth at 10 cm (3.9 in) intervals. Samples were analyzed for bulk density, saturated hydraulic conductivity (K sat ), soil water retention, and pore-size distributions. ]), and was significantly different throughout the soil profile, except for the 20 to 30 cm (7.9 to 12 in) depth. These results show that row crop management and its effect on soil loss have significantly altered the hydraulic properties for this soil. Results from this study increase our understanding of the effects of long-term soil management on soil hydraulic properties.

“…A few studies have suggested that planting switchgrass and other WSGs for bioenergy on sloping marginal lands not only provides cellulosic biomass but also improves ecosystem services such as reducing water erosion and improving soil and water quality, soil C sequestration, and biodiversity (Gilley et al, 2000;Rachman et al, 2004;Blanco-Canqui et al, 2014). Growing deep-rooted WSGs in fields with steep slopes can anchor and stabilize the soil while improving soil properties at deeper depths in the profile.…”

Marginal lands are candidates for growing dedicated energy crops such as perennial warm-season grasses (WSGs) and short-rotation woody crops (SrWCs), but actual field data on ecosystem services have not been widely discussed. This review (i) discusses potential marginal lands studied for energy crop production, (ii) considers the impacts of energy crops on ecosystem services, and (iii) underlines research needs. Some marginal or degraded lands studied for energy crops include highly erodible, flood-prone, compacted, saline, acid, contaminated, or sandy soils, reclaimed minesoils, urban marginal sites, and abandoned or degraded croplands. Field data are few but indicate that ecosystem services vary with the type of marginal land, management (i.e., fertilizer or amendment rates), and perennial species. M arginal lands are candidates for growing dedicated bioenergy crops, such as perennial WSGs and SRWCs, to reduce competition for land between energy and food production. Marginal lands can be defined as soils that have physical and chemical problems or are uncultivated or adversely affected by climatic conditions. The potential of marginal lands for growing WSGs and SRWCs as biofuel has received increased attention in recent years. Several questions remain, however, about which and how to grow dedicated energy crops on marginal lands, how dedicated energy crops will perform on different types of marginal lands, and whether these sites can produce abundant biomass while maintaining or improving ecosystem services.Many have used models to address the above questions and estimate the global and regional potential of marginal lands for cellulosic biomass production. These modeling studies have suggested that marginal lands offer a large potential for producing dedicated bioenergy crops while sequestering soil C, reducing net greenhouse gas emissions, and improving water quality (Davis et al., 2010;Gelfand et Humberto Blanco-Canqui* Core Ideas• Dedicated bioenergy crops can enhance ecosystem services in marginal lands.• Ecosystem services vary with the type of marginal land.• More field data are needed about the performance of energy crops on marginal lands.

“…Saturated hydraulic conductivity and water infiltration rates are important to reducing runoff (Rachman et al 2004b;Gilley et al 2000) and soil bulk density is often reduced and macroporosity increased with soil under perennial grass (Rachman et al 2004a). Filters are expected to be relatively ineffective in cases of slow water infiltration such as with frozen, saturated, or compacted soils or soils of weak aggregation.…”

Surface water contamination can often be reduced by passing runoff water through perennial grass filters. Research was conducted in 2006 to 2008 to evaluate the size of cool season grass filters consisting primarily of tall fescue (Festuca arundinacea Schreb) with some orchard grass (Dactylis glomerata L.) relative to drainage area size in reducing runoff sediment and phosphorus (P). The soil was Pohocco silt loam Typic Eutrochrepts with a median slope of 5.5 %. The grass filters occupying 1.1 and 4.3 % of the plot area were compared with no filter with four replications. The filters were planted in the Vshaped plot outlets which were 3.7 × 11.0 m in size. The filter effect on sediment and P concentration was determined from four natural runoff events when nearly all plots had runoff. Filter effect on runoff volume and contaminant load was determined using total runoff and composites of samples collected from 12 runoff events. Sediment concentration was reduced by 25 % with filters compared with no filter (from 1.10 to 1.47 g L −1 ), but P concentration was not affected. The 1.1 and 4.3 % filters, respectively, compared with having no grass filter, reduced: runoff volume by 54 and 79 %; sediment load by 67 and 84 % (357 to 58 kg ha −1 ); total P load by 68 and 76 % (0.58 to 0.14 kg ha −1 ); particulate P (PP) load by 66 and 82 % (0.39 to 0.07 kg ha −1 ); and dissolved reactive P (DRP) load by 73 and 66 % (0.2 to 0.07 kg ha −1 ), respectfully. A snowmelt runoff event had 56 % greater DRP concentration compared with rainfall-induced runoff events. Grass filters reduced sediment and P load largely by reducing runoff volume rather than reducing concentration. Well-designed and well-placed grass filters that occupy 1.0 to 1.5 % of the drainage area and intercept a uniform flow of runoff from a drainage area can reduce sediment and nutrient loss in runoff by greater than 50 %.
