“…This demonstrates that crop yields were not compromised by the OMF formulations up to 200 kg N ha −1 , but in addition there was no yield benefit from incorporating higher amounts of urea into the BS. Barbarick et al (2012) also found that BS produced wheat yields that were comparable to commercial N fertiliser in a no-till dry-land system. However, the current study demonstrates reduced yields where urea alone was applied at 250 kg N ha −1 (2011 yield).…”

“…O ne major reason that the USEPA promotes biosolids land application (USEPA, 1993) is to enhance the opportunity to recycle plant nutrients such as N, P, Zn, Cu, Fe, and Ni (Barbarick and Ippolito, 2007), as well as maintain crop yields (Barbarick et al, 2012). Numerous statistical analyses of biosolids effects on crop growth have been reported.…”

Meta‐Analyses of Biosolids Effect in Dryland Wheat Agroecosystems

Land application to cropping systems is USEPA's preferred method of recycling biosolids. Determination of biosolids effect size through meta-analyses from two decades of field-location research at three sites should answer the question: Does 20 yr of biosolids application affect dryland wheat ( L.) grain production, grain nutrient concentrations, and soil elemental extractability compared with equivalent rates of commercial N fertilizer? At two sites, biennial biosolids application rates to a wheat-fallow (WF) rotation were up to 11.2 dry Mg ha and up to 112 kg commercial N fertilizer ha, whereas rates at the third location varied to match soil-test information. Crop rotations included WF and wheat-corn ( L.)-fallow. We completed meta-analyses of biosolids effects compared with N fertilizer on wheat yield, grain protein, grain total, and soil ammonium bicarbonate-diethylenetriaminepentaacetic acid (ABDTPA)-extractable P, Zn, Cu, Fe, and Ni concentrations at the aforementioned sites from 1993 through 2013. Results showed that biosolids produced greater grain P and Zn at one site. Biosolids rates at two sites resulted in greater grain Zn and ABDTPA P, Zn, Cu, and Fe. Meta-analyses tests for heterogeneity indicated that the variance for all sites and rates could be explained as consistent across treatments, whereas the test for the 20 yr showed that heterogeneity was large and other factors affected the variance (e.g., climatic variability between years). Meta-analysis showed the practical effect of biosolids over a 20-yr study and demonstrated that the primary biosolids effect was an improvement in Zn availability to wheat.

“…While biosolids applications generally raise grain protein when applied during the fallow year (Cogger et al, 2013), practical experience suggests that this is generally not great enough to negatively impact prices for soft wheats that can have high protein penalties. Likewise, the risk of N and P losses after biosolids applications is most often relatively low in regional dryland cereal systems, especially for one-time applications (Ippolito et al, 2007;Barbarick et al, 2012;Cogger et al, 2013). These anaerobically digested biosolids were later shown to also build stable and more labile soil organic C and N, while supplying sufficient crop N to a wheat-fallow system .…”

“…Biosolids applications can build soil C while producing equivalent or better grain yields than typical applications of inorganic N in tilled and untilled wheat systems (Koenig et al, 2011;Barbarick et al, 2012). These increased yields are often attributed to the phosphorus, sulfur and micronutrients provided by the biosolids (Ippolito et al, 2007).…”

Climate-friendly best management practices for mitigating and adapting to climate change (cfBMPs) include changes in crop rotation, soil management and resource use. Determined largely by precipitation gradients, specific agroecological systems in the inland Pacific Northwestern U.S. (iPNW) feature different practices across the region. Historically, these farming systems have been economically productive, but at the cost of high soil erosion rates and organic matter depletion, making them win-lose situations. Agronomic, sociological, political and economic drivers all influence cropping system innovations. Integrated, holistic conservation systems also need to be identified to address climate change by integrating cfBMPs that provide win-win benefits for farmer and environment. We conclude that systems featuring short-term improvements in farm economics, market diversification, resource efficiency and soil health will be most readily adopted by farmers, thereby simultaneously addressing longer term challenges including climate change. Specific "win-win scenarios" are designed for different iPNW production zones delineated by water availability. The cfBMPs include reduced tillage and residue management, organic carbon (C) recycling, precision nitrogen (N) management and crop rotation diversification and intensification. Current plant breeding technologies have provided new cultivars of canola and pea that can diversify system agronomics Pan et al.Win-Win Scenarios for Farm and Climate and markets. These agronomic improvements require associated shifts in prescriptive, precision N and weed management. The integrated cfBMP systems we describe have the potential for reducing system-wide greenhouse gas (GHG) emissions by increasing soil C storage, N use efficiency (NUE) and by production of biofuels. Novel systems, even if they are economically competitive, can come with increased financial risk to producers, necessitating government support (e.g., subsidized crop insurance) to promote adoption. Other conservation-and climate change-targeted farm policies can also improve adoption. Ultimately, farmers must meet their economic and legacy goals to assure longer-term adoption of mature cfBMP for iPNW production systems.
