“…The literature contains many reports of studies that have demonstrated the adverse impact of burning crop residues in decreasing infiltration rates and increasing surface runoff and erosion (e.g. Steichen et al, 1987;Albrecht et al, 1995;Wuest et al, 2005), and the post-harvest burning in the study field prior to the period of heavy rain is likely to have had a similar effect.

“…The manure amendments added the largest amounts of C (about 169 g m -2 yr -1 ) and N (14 g m -2 yr -1 ), and increased SOC the most. The relatively small input of pea vine (about 82 g m -2 yr -1 ) produced substantially more SOC than winter wheat-fallow plots which received equal or greater amounts of N fertilizer (see also Wuest et al, 2005). Synthetic fertilizer rates in the experiment have increased over the decades to reflect modern farming systems, and therefore SOC may have changed from one equilibrium state or input rate to another.…”

The amount and type of C‐containing amendments applied to soil can have an influence on soil organic carbon (SOC) levels. To test the hypothesis that amendment type is more important than amount, we applied 250 g C m−2 as manure, legume foliage, wheat (Triticum aestivum L.) residue, municipal biosolid, wood sawdust, brassica (Brassica napus L.) residue, composted wheat residue, sucrose, and cotton linters to both fallow soil and an annual winter wheat crop for five consecutive years. After an additional 3.5 yr with no inputs and all plots being fallow, the SOC of biosolid, manure, and wood amended plots were significantly (P < 0.0001) greater than the unamended check. The application of biosolid increased SOC 492 g m−2, and manure increased SOC 316 g m−2, over the fallow check plots in the top 300 kg m−2 of soil (approximately 0–25 cm). The increase in SOC relative to the check ranged from 0 to 39% of the amendment C applied. The SOC content was 482 g m−2 greater under continuous winter wheat than under fallow. The amendment and wheat crop effects on soil C and N changed little during the 3.5 yr after treatments ended, indicating that decomposition occurred soon after application. Wood sawdust was unique in that it increased SOC even though it was low in N content, and it changed the soil C/N ratio from 12.3 to 13.4. This field research demonstrated that amendments applied at the same C rate can have variable effects on SOC accretion.

“…Ground cover by crop residues physically protects the soil surface from raindrop impact and, by contributing to soil organic C, increases biological activity, aggregate stability, porosity, and water infiltration (Doran 1980a(Doran , 1980bWuest et al 2005Wuest et al , 2006. Residue cover also reduces rill erosion by reducing shear stress of concentrated flow erosion (Knapen et al 2008;McCool et al 1995;Van Liew and Saxton 1983;Zuzel and Pikul 1993).…”

“…An increase in crop frequency leads to a corresponding reduction of fallow, which has been shown to either stabilize or improve soil organic matter levels and reduce the frequency of winters during which the soil lies unprotected (Rasmussen et al 1998b;Sherrod et al 2003). Improved levels of soil organic matter have been shown to promote soil aggregation and infiltration (Wuest et al 2005), resulting in improved soil and water conservation (Williams et al 2009). In the Pacific Northwest, control of winter annual broadleaf weeds and annual grasses, especially downy brome (Bromus tectorum) and rattail fescue (Vulpia myuros L.C.C.…”

Abstract:The winter wheat (Triticum aestivum L.)/summer fallow rotation typically practiced in the intermediate precipitation zone (300 to 450 mm [12 to 18 in]) of the inland Pacific Northwest has proven to be economically stable for producers in this region. However, multiple tillage operations are used to control weeds and retain seed-zone soil moisture, which disturbs the soil and makes it prone to substantial erosion. Alternatives to this conventional disturbance tillage (DT) system include either no-tillage (NT) or minimum tillage (MT) in combination with increasing cropping intensity. The objective of this study was to compare runoff, soil erosion, crop residue, and yield productivity resulting from NT, and DT, or MT. Small collectors and flumes were used to quantify runoff and soil erosion from small drainages and slopes in three different experiments near Pendleton, Oregon. The first experiment included two neighboring drainages: one farmed using DT with a two-year crop rotation over eight years (2001 to ) from MT. Soil erosion was found to be DT > NT in a ratio of 5:1 at the first site and 2:1 for the second site. For small collectors the differences were significant: runoff was DT > NT in a ratio of 47:1 for the first site, and MT > NT in a ratio of 2:1 for the third site. Winter wheat yields did not differ significantly among NT, DT, and MT. Broader acceptance of NT cropping systems in the intermediate precipitation zone of this region would substantially decrease soil losses from farm fields and improve downstream water quality.
