Abstract

Potential carbon mineralization (Cmin) is a commonly used indicator of soil health, with greater Cmin values interpreted as healthier soil. While Cmin values are typically greater in agricultural soils managed with minimal physical disturbance, the mechanisms driving the increases remain poorly understood. This study assessed bacterial and archaeal community structure and potential microbial drivers of Cmin in soils maintained under various degrees of physical disturbance. Potential carbon mineralization, 16S rRNA sequences, and soil characterization data were collected as part of the North American Project to Evaluate Soil Health Measurements (NAPESHM). Results showed that type of cropping system, intensity of physical disturbance, and soil pH influenced microbial sensitivity to physical disturbance. Furthermore, 28% of amplicon sequence variants (ASVs), which were important in modeling Cmin, were enriched under soils managed with minimal physical disturbance. Sequences identified as enriched under minimal disturbance and important for modeling Cmin, were linked to organisms which could produce extracellular polymeric substances and contained metabolic strategies suited for tolerating environmental stressors. Understanding how physical disturbance shapes microbial communities across climates and inherent soil properties and drives changes in Cmin provides the context necessary to evaluate management impacts on standardized measures of soil microbial activity.

Abstract

Nitrogen (N) captured by cover crops can be recycled for use by the following crop via decomposition and net mineralization. This study assessed the magnitude of inorganic‐N released from radish (Raphanus sativus L.) and cereal rye (Secale cereale L.) residue. The experiment was designed using a five by two factorial treatment structure with five cover crop residue treatments (radish shoots, radish roots, whole radish, cereal rye shoots, and no cover crop) and two levels of residue incorporation (incorporated and surface applied). Cover crop residues were applied to a silt loam soil on an equivalent N basis, incubated for 25 weeks and sampled periodically. Generally, NH4‐N concentration increased for 7–11 days after residue application, after which, NH4‐N concentration declined and NO3‐N concentration increased due to nitrification. Mineralization during the later days (42–179 days after residue application) was negligible from radish residue, but cereal rye shoots and radish roots released significant amounts of NH4‐N, which decreased over the last 137 d. Radish roots generated significantly more NO3‐N from day 42 through 141 than any other residue, while cereal rye shoots mineralized the least amount of NO3‐N from day 42 through 86. Incorporating cereal rye residue increases the occurrence of immobilization within the first 35 days after residue application; however, incorporation increases the rate at which NO3‐N is released from residues between 42 and 179 days after residue addition, regardless of cover crop species. Incorporation of residue can increase N mineralization rate, but the effect varies across cover crop species. Core Ideas: Cover crop species influences rate of residue decomposition and mineralization of N.Immobilization of N was lower for radish residue than cereal rye regardless of incorporation.Nitrate concentrations were similar for all cover crop residues following 154 days of incubation.

7. 15N fertilizer recovery and partitioning by cover crops under greenhouse conditions.

Author

Greub, Kelsey L. H. and Roberts, Trenton L.

Abstract

Cover crops have the potential to decrease residual‐nitrogen (N) losses from agricultural soils by capturing and storing excess N between cash crops. This study was established to assess the effect of cover crop species and N rate on the accumulation and partitioning of biomass and 15N fertilizer by cover crops produced under controlled environmental conditions. Cereal rye (Secale cereale) and tillage radish (Raphanus sativus) cover crops were grown in monoculture and in a blend under greenhouse conditions in two soils. Urea enriched with 15N (3.0 atom %) was applied to cover crops at rates of 0, 34, and 67 kg N ha−1. Shoot dry matter production and N accumulation exceeded that of roots for both cover crops. Fertilizer‐N uptake increased as application rate increased, and the greatest overall recovery by the cover crops was 38% of the applied fertilizer‐N. Tillage radish shoot biomass nearly doubled that of cereal rye (1,585 kg ha−1) when grown in monoculture in the Captina soil but cover crops stored similar quantities of total N in the shoots. Cover crops grown in monoculture in the Roxanna soil accumulated similar amounts of biomass and TN in the shoots; however, cereal rye root biomass was twice that of tillage radish (568 kg ha−1) when 67 kg N ha−1 was applied. Results from this study reflect the capacity for N sequestration by cover crops, which is largely determined by biomass production and N availability, and most of the captured N is translocated and stored in the shoots.
