“…However, water quality data were not reported. There have been several other studies conducted where swine manure was applied to tile‐drained land where water quality data were reported (e.g., Dougherty et al., 2020; Nila Rekha et al., 2011), but these studies did not include relevant soils information. Both studies concluded that although swine manure application increases nitrate concentrations in drainage water, best management practices can reduce nitrate loss to groundwater.…”

A comprehensive review of research data on the effects of swine manure on soil health properties that is applicable to agricultural producers is lacking. The objectives of this review were (a) to synthesize literature describing effects of swine manure on soil properties that affect “soil health” and (b) to identify knowledge gaps and research needs to further our understanding of this topic. We reviewed papers from two databases and extracted soil property and swine manure data based on a set of criteria. For a paper to be included, (a) the studies were replicated field experiments, (b) manure was the only differing factor between or among treatments, and (c) data means of swine manure amended treatments and controls were included. In total, 40 papers met the criteria and were included. Based on this review, swine manure has the potential to significantly increase soil organic carbon. Soil organic carbon, soil organic matter, and microbial biomass carbon increased when swine manure was applied to crop fields, whereas bulk density tended to decrease. To conclude, previous literature reviews failed to account for differences in methodologies between individual research studies and whether research is applicable to producers utilizing swine manure as amendments to improve soil health. Future research studies should measure and report a standard set of metrics for both soil and manure properties and should investigate the effects of application frequency on short‐ and long‐term soil health properties.

The addition of cover crops and minimum tillage to current row‐crop production practices in the mid‐southern United States could holistically improve the sustainability of these farming systems. This relatively short‐term study was conducted to determine if the addition of these practices into corn (Zea mays L.)–soybean [Glycine max (L.) Merr.] rotational systems in the region would decrease irrigation water use while improving yield, irrigation water use efficiency, and net returns above production costs. The effects of cover crops and minimum tillage on these parameters were investigated from 2017 to 2019 on six pairs of production fields in northwest Mississippi. A pair was created by dividing a single field that had been under uniform management into two fields that were land leveled and hydrologically separated with an earthen berm. Control fields were managed according to standard practices within the region, which include winter fallow and multiple tillage passes, whereas treatment fields were managed with winter cover crops and minimum tillage. The addition of cover crops and minimum tillage had no effect on yield (p = .09), irrigation water use efficiency (p = .38), or irrigation water applied (p = .83). The net economic return on average across all site years was a loss of US$233 ha–1. These results reflect the short study period as changes resulting from these practices often occur on a greater time scale. The value proposition for adoption of a cover crop–minimum tillage system will be challenging in the mid‐southern United States if potential benefits are to be expected in the early years of adoption.

“…Although spring 2013 percolation was not the largest among the experimental years, it followed a dry year (2012) with a greater application rate where minimal leaching losses were observed. Poor crop growth and crop N uptake during dry years could leave substantial residual N in the soil, which could be flushed from the vadose zone in the following spring (Dougherty et al., 2020). As winter and spring precipitation for the Assiniboine‐Red River basin increase due to climate change, it is possible to expect increased NO 3 –N leaching losses in the future, mostly associated with high spring percolation.…”

The seasonality of nitrate and phosphorus leaching from manure and chemical fertilizer added to a chernozemic soil in Canada

Identifying seasons sensitive to nutrient losses could help farmers and policymakers to formulate effective nutrient loss reduction strategies. This long-term study monitored water percolation as well as nitrate (NO 3 -N) and total phosphorus (TP) leaching from liquid swine manure and chemical fertilizer applied to intact core lysimeters in a sandy loam soil in Manitoba, Canada. Water percolation, NO 3 -N, and TP leaching were monitored from 2005 to 2016. Chemical fertilizer showed greater average annual mean water percolation (p = .01), annual flow-weighted mean concentration (FWMC) of NO 3 -N (22 mg L -1 ; p < .001), and annual NO 3 -N leaching (36 kg N ha -1 ; p = .002) compared with the manure treatment (FWMC NO 3 -N, 15 mg L -1 ; NO 3 -N leaching load, 22 kg N ha -1 ). Average annual mean TP loss did not differ between treatments (p = .86). Spring (April-June) was the most sensitive season, when >75% of annual percolation, >80% of annual NO 3 -N, and >68% of annual TP leaching losses occurred from both manure and chemical fertilizer. Annual NO 3 -N and TP leaching increased exponentially with cumulative winter and spring precipitation (control, r 2 = .69; manure, r 2 = .79; chemical fertilizer, r 2 = .63) and decreased with winter and spring air temperatures. The largest spring NO 3 -N and TP leaching losses were observed in 2013, which followed the dry year of 2012, indicating the potential for nutrient flushing. The findings emphasize the need for environmentally sound N and P management strategies in cold North American regions underlain by coarse-textured soils, particularly during the spring season.
