“…Diversified cropping systems and no‐till (NT) provide many functional complementary benefits to the soils (Verhulst et al, 2011), primarily due to increased soil organic carbon (SOC) and total nitrogen (N) content (Maiga et al, 2019). Despite the success of NT adoption in the Midwestern Corn Belt of the United States (Horowitz, Ebel, & Ueda, 2010), this region is, however, marked by a low crop diversity due to predominance of the maize‐soybean rotation (Chatterjee, Cooper, Klaustermeier, Awale, & Cihacek, 2016) and long periods of autumn–winter fallow. Therefore, in the long run, reduced agricultural crop biodiversity has the potential to alter soil organic matter (SOM) contents (Halvorson & Schlegel, 2012) and belowground soil biochemical processes (McDaniel, Tiemann, & Grandy, 2014).…”

“…Determination of different labile fractions of SOM is now considered an efficient tool to detect shifts in carbon and nitrogen pools due to soil management, compared with the total SOM (Chatterjee et al, 2016; Insam & Domsch, 1988). For instance, water‐extractable and microbial biomass‐defined fractions are increasingly used to interpret the active carbon status in the soil because of its rapid turnover time (Ghani, Dexter, & Perrott, 2003) and direct participation in biochemical transformation of nutrient cycling (Lagomarsino et al, 2009).…”

Quantifying changes in soil biochemical properties is important in understanding the response to soil management practices. Our objectives were to evaluate the single and combined effects of three different crop rotations (maize (Zea mays)‐soybean (Glycine max) (2 years), maize‐soybean‐oat (Avena sativa) (3 years), maize‐soybean‐oat‐winter wheat (Triticum aestivum) (4 years)), and two winter cover‐type (cover crop and no cover crop) managements under long‐term conventional‐till (CT) and no‐till (NT) systems on water‐extractable carbon and nitrogen fractions, microbial biomass carbon (MBC) and enzymatic activities. The experimental site under silty clay loam in southeastern South Dakota was sampled before planting in early spring, after planting in early summer, and during the maize grain‐filling stage in early autumn of 2017, from the surface 0–7.5‐cm depth in 2017. In general, the cover crops had 9, 17 and 19% higher geometric mean of enzyme activities than the no‐cover‐crop plots at pre‐planting, after planting and the grain‐filling stage of maize, respectively. Although there were not many differences between “NT vs. CT” and “2‐year vs. 3‐year vs. 4‐year rotation” treatments, additive effects between “tillage and cover crops” and “rotation and cover crops” were observed. The MBC and β‐glucosidase activity were 31 and 54% higher, respectively, with cover crop vs. no cover crop under 4‐year rotation after planting of maize. Similarly, significant interactions between “cover crop and tillage” for hot water‐extractable nitrogen and urease activity at pre‐planting, and β‐D‐glucosidase after planting of maize, were observed. At the grain‐filling stage, the hot water‐extractable contents were significantly greater under cover crop as compared to the no‐cover‐crop plots. Furthermore, this study also concluded that seasonal fluctuations are important for understanding the management impacts on soil carbon fractions and biochemical properties. Highlights Soil microbial properties responded differently to tillage, rotation and cover crops during the maize growing season. Residues produced by cover crops during winter fallow impacted soil functioning and interacted with other management factors (rotation and tillage system). Rotation impacted the carbon availability after planting, whereas tillage affected the enzyme activities. Winter cover crops influenced labile soil organic matter (SOM) and enzymatic properties after 4 years.

“…The relationships among soil biochemical health tests are not straight-forward [7]. Moreover, their relationship and sensitivity are strongly influenced by landscape characteristics [8], inherent soil properties like texture [9] and crop and soil management practices like tillage and rotation [10] [11] [12]. Some soil biological tests are more sensitive to shift with soil factors than other tests.…”

Numerous soil biochemical methods are used to determine the soil health status, but the relationships among these methods are not well understood. Relationships among soil biochemical tests, 1) chloroform fumigated microbial biomass C (CFMBC), 2) permanganate oxidizable C (POXC), 3) Solvita CO 2-burst (Solvita), 4) Solvita labile amino nitrogen (SLAN), and short-term soil CO 2 efflux during laboratory incubation using (v) Alkali-base trap (Alkali) and (vi) infrared gas analyzer (IRGA), were evaluated for nine agricultural soils collected across the Red River Valley of North Dakota and Minnesota, USA. Not a single test is comprehensive to relate with all soil biochemical tests. Coefficient of variation percentage for particular method varied with soil type. Among six tests, CFMBC is significantly (p < 0.05) related with Alkali (r = 0.37), Solvita (r = 0.57), SLAN (r = 0.52), and POXC (r = 0.68). Soil CFMBC correlates with most of soil biochemical tests and can be potential to determine soil biochemical condition.

“…Increasing global warming demands increased focus on C sequestration of atmospheric carbon dioxide in agricultural soils. Soil quality is directly affected by soil organic C (SOC) as a consequence of its crucial impact on soil properties Crop rotational diversity is an efficient way to improve agroecosystem health over time with increased crop production and reduced fertilizer-N requirement (Chatterjee et al, 2016;Liebig et al, 2006;Sanchez et al, 2001). The capability of crop rotation to alter the composition of soil microbial population and belowground biochemical processes can induce changes in SOC and N (McDaniel et al, 2014;Plaza et al, 2013).…”

Soil C and N sequestration using conservation practices to alleviate climate change are necessary; however, diverse crop management influences on aggregate-associated C and N levels need consideration. Our objective was to compare bulk soil and aggregate-associated C and N under cover crops hairy vetch (Vicia villosa Roth) and winter wheat (Triticum aestivum L.), poultry litter application, fallow control, and crop rotations of continuous cotton (Gossypium hirsutum L.), cotton-corn (Zea mays L.), continuous corn, corn-soybean [Glycine max (L.) Merr.], continuous soybean, and soybean-cotton in a long-term (2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017)(2018) no-tillage field experiment at Milan, TN. Soil organic C (SOC) and N were assessed at 0-15 and 15-30 cm bulk soil and in >2, 0.25-2, 0.053-0.25, and <0.053 mm aggregates at depths 0-5, 5-10, 10-15, and 15-30 cm. In 0-15 cm, poultry litter resulted in 4.14, 3.92, and 3.48 Mg ha -1 significantly (P ≤ .05) higher SOC, and 0.50, 0.52, and 0.44 Mg ha -1 significantly higher N than hairy vetch, wheat, and fallow, respectively. Continuous corn and corn-soybean showed significantly higher SOC content in >2 and 0.25-2 mm at 0-5 cm, whereas in other crop rotations, 0.25-2 mm exhibited significantly higher SOC content than >2 mm. Poultry litter had significantly higher soil N in >2 and 0.25-2 mm at 0-5 cm than hairy vetch, wheat, and fallow. Inclusion of continuous corn or rotation of corn and soybean, integrated with poultry litter applied as manure, can serve as SOC and N sinks in macroaggregates enhancing C and N sequestration under no-till management and humid subtropical climate.
