Soil health (Sh) refers to the ability of a soil to function and provide ecosystem services. The Comprehensive Assessment of Soil health (CASh) is an approach that measures 15 physical, biological, and chemical soil indicators, which are interpreted through scoring functions. This study reports on the Sh status of 5767 samples from the mid-Atlantic, midwest, and northeast regions of the uSA as evaluated using CASh. descriptive statistics and AnOvAs of subdatasets by region and soil textural group for Sh indicators, in addition to correlation coefficients, principal component (pC) analysis, and best subsets regression (BSr) were performed. from these analyses, new CASh scoring functions were developed. Separate scoring functions by textural group (fine, medium, coarse) were necessary for Wet Aggregate Stability (WAS), Available Water Capacity (AWS), Organic matter (Om), Active Carbon (AC), and protein. differences existed among regions, especially for WAS, Om, protein, and respiration (resp), where the midwest had relatively lower mean values compared to the mid-Atlantic and northeast. Biological properties and WAS showed moderately strong correlations (r = 0.58-0.78) and the highest loadings for the first two pCs. BSr results using the overall soil quality index as the response variable indicated that AC accounts for 45% of the variation, with additional predictability from penetration resistance, resp, and WAS (68%). These four indicators are suggested for simplified Sh tests. We conclude that the CASh approach can be successfully applied to evaluate the health status of soils with differing pedogenetic histories. C onceptually, soil health (SH) represents the emerging understanding of soil quality. Both terms refer to the ability of a soil to function and provide ecosystem services based on its inherent characteristics (e.g., texture, mineralogy) and environmental conditions (Karlen et al., 1997;Andrews et al., 2004;Idowu et al., 2009). A soil's health status, within the context of land use and management goals, however, is consistent with the understanding of soils as a dynamic, complex, and living system (Doran and Zeiss, 2000). Intensive agriculture and poor land management practices have led to widespread soil degradation associated with increasing topsoil erosion, nutrient depletion, pollution, compaction, and loss of organic matter (Matson et al., 1997). A sustainable future with an ever-growing global population depends on healthy, well-functioning soils, which increase water and air quality, sup- Core Ideas• Summary statistics were developed from a robust multiregional soil health (Sh) dataset.• Active carbon, organic matter, and penetration resistance were most useful soil health indicators.• midwestern soils had relatively lower mean values for measured biological properties than northeast or mid-Atlantic soils.

“…For Method 2, 200-300 g of equivalent dry soil were used and maintained at 17.7°C ± 0.4°C and 15 30% of maximum water holding capacity (WHC) for 2 weeks until the gas exchange measurements were performed. Prior to this incubation period, the WHC of each soil was estimated using the method of Haney and Haney (2010) and, when fresh soils were too wet (> 30% WHC), they were air-dried until they reached 10-20% WHC, then re-humidified to 30% WHC at the start of the 2-week incubation period. Throughout this incubation period, moisture contents were monitored gravimetrically and maintained by adding distilled water.…”

Abstract. Soils both emit and consume the trace gas carbonyl sulphide (COS) leading to a soil-air COS exchange rate that is the net result of two opposing fluxes. Partitioning these two gross fluxes and understanding their drivers are necessary to 10 estimate the contribution of soils to the current and future atmospheric budget of COS.Previous efforts to disentangle the gross COS fluxes from soils have used flux measurements on air-dried soils as a proxy for the COS emission rates of moist soils. However, this method implicitly assumes that COS uptake becomes negligible and COS emission remains steady while soils are drying. We tested this assumption by estimating simultaneously the soil COS sources and sinks and their temperature sensitivity (Q10) from soil-air COS flux measurements on fresh soils at different COS 15 concentrations and two soil temperatures. Measurements were performed on 27 European soils from different biomes and land use types in order to obtain a large range of physical-chemical properties and identify the drivers of COS consumption and production rates.We found that COS production rates from moist and air-dried soils were not significantly different for a given soil and that the COS production rates had Q10 values (3.96 ± 3.94) that were larger and more variable than the Q10 for COS consumption 20(1.17 ± 0.27). COS production generally contributed less to the net flux that was dominated by gross COS consumption but this contribution of COS production increased rapidly at higher temperature, lower soil moisture and lower COS concentrations. Consequently, measurements at higher COS concentrations (viz. 1000 ppt) always increased the robustness of COS consumption estimates. Across the range of biomes and land use types, COS production rates co-varied with total soil nitrogen (r = 0.68, P < 0.05) and the first-order COS uptake rate co-varied most with microbial N content (r = 0.64, P < 0.05) 25providing new insights on how to upscale the contribution of soils to the global COS atmospheric budget.Atmos.

The effectiveness of chemical amendment of pig slurry to ameliorate phosphorus (P) losses in runoff is well studied, but research mainly has concentrated only on the runoff pathway. The aims of this study were to investigate changes to leachate nutrient losses, soil properties and greenhouse Morgan's phosphorus and water extractable P content of the soil to that of the soil-only treatment, indicating that they have the ability to reduce P loss in leachate following slurry application. There were no significant differences between treatments for nitrogen (N) or carbon (C) in leachate or soil, indicating no deleterious impact on reactive N emissions or soil C cycling. Chemical amendment posed no significant change to GHG emissions from pig slurry, and in the cases of alum and PAC, reduced cumulative N 2 O and CO 2 losses. Chemical amendment of land applied pig slurry can reduce P in runoff without any negative impact on nutrient leaching and GHG emissions. Future work must be conducted to ascertain if more significant reductions in GHG emissions are possible with chemical amendments.
