“…Studies have highlighted that SOM content is directly related to the amount of residue maintained on the soil [7]. Furthermore, crop residues remaining on the fields are not a waste but provide numerous ecosystem services including SOC sequestration, being a direct source of SOC pool [8]. The availability of crop byproducts is then related to the quantity that can be removed from the soil to maintain its fertility and to other uses as those related to industrial and agricultural sectors.…”

A big amount of agricultural residues are generated from crop production and partially remain in the field after harvest. Removing the excess of residues after crop harvesting can increase farmer income, providing feedstock that could be used for industrial and energy purposes. The costs for collection and transport of straw and stalks are site- and region-specific and depend on the availability of agricultural residue and on how much of the residue is removed from any specific field or location. If the biomass is baled then it is required to upload the bales on a trailer, transport and unload all the baled biomass to the storage center. On the other hand, if a self-loading wagon is used the loose biomass collected, it must be unloaded every time the wagon is completely full. The distance and the harvesting system used influence the costs and should be analytically studied to avoid turning a possible profit into a disadvantageous business. The research represents a real case study to evaluate, which is the maximum distance to the biomass logistic center from which it is more economically convenient to gather the wheat and corn residues in bales instead of using a self-loading wagon. The results show a lower harvesting unitary cost for the self-loading forage wagon respect to the baling system. Although the study showed delivery distances over 11.4 km for wheat straw and 16.0 km for maize stalks, the use of the self-loading forage wagon is no longer convenient, and baling is the preferred harvesting system.

Diversification within a cropping system together with no-till (NT) soil management can help to improve soil organic carbon (SOC). The present study was conducted to assess the impacts of crop diversity through crop rotations on SOC and other selected soil properties. The long-term experimental sites were located in Beresford and Brookings, South Dakota, USA. The Beresford site was initiated in 1991 (24 years) on Egan soil series (fine-silty, mixed, superactive, mesic Udic Haplustolls), whereas, the Brookings site was established in 2000 (14 years) on a Barnes clay loam soil (fine-loamy, mixed, superactive, frigid Calcic Hapludolls) under a randomised complete block design with four replications. Treatments at both sites consisted of a 2-year (corn (Zea mays L.)–soybean (Glycine max L.)), and a 4-year (corn–soybean–winter wheat (Triticum aestivum L.)–oat (Avena sativa L.)) rotation, all managed under NT soil management. Soil samples were collected in the fall of 2015 after crop harvest under the corn phase. Data showed that 4-year rotation increased SOC stock (8.3% in Brookings and 22% in Beresford) compared with that under 2-year rotation (not always significant) in the soil profile 0–60cm. Soil particulate organic matter and organic matter were always higher under 4-year rotation than under 2-year rotation at 0–5 and 5–15cm depths at both sites. Surface soil aggregate stability was improved in both locations under 4-year rotation (12% in Brookings, 4% in Beresford). Additionally, at 0–5cm depth, the 4-year rotation increased light fractions of carbon (18% in Brookings, and 32% in Beresford) compared with 2-year. Results from this study showed that the use of diverse crop rotations (4-year) for longer (>24 years) duration enhanced SOC, carbon and nitrogen fractions, and soil aggregation compared with those under corn–soybean (2-year) rotation.
