Kinetic Analysis of Net Nitrogen Mineralization in Soil

Soil Science Society of America Journal (1984)

N. G. Juma E. A. Paul Bruno Mary

Abstract Studies were conducted to determine the most suitable mathematical equation and the most appropriate method for calculating the values of the parameters of the equation describing the net N mineralization in soil. The cumulative net N mineralized in two treatments of a 15 N labeled soil and five unlabeled Saskatchewan soils showed curvilinear trends that could be fitted to either hyperbolic or first order equations. The kinetic parameters of the hyperbolic equation, 15 N H 0 (potentially mineralizable N) and T c (time required for 1/2 N H 0 to mineralize) determined by nonlinear least squares (NLLS) yielded the best fit to the data for the labeled soil and had the lowest RMS error. Linear regression (1/N vs 1/ t ) yielded 15 N H 0 and T c values which were markedly different than those obtained with the N vs. N/ t and t /N vs. t transformations or those obtained with the NLLS method when all the data were considered. The double reciprocal plot gave undue weight to the initial data points. The 15 N H 0 estimated by NLLS method accounted for 62 and 72% of the total organic 15 N remaining in the two treatments of Weirdale loam soil. The N H 0 for Saskatchewan soils ranged from 51 to 429 µg N g −1 soil, while the T c ranged from 7.3 to 45.8 weeks. The 15 N F 0 values obtained with the first order equation using NLLS method accounted for 39 to 44% of the total organic 15 N remaining in soil. The N F 0 values for Saskatchewan soils ranged from 35 to 255 µg N g −1 soil while the values of net mineralization rate constant, k , ranged from 0.036 to 0.164 weeks −1 . Both equations accurately predicted the amount of net N mineralized over 14 weeks incubation. However, the estimates of potentially mineralizable N and mineralizable N half‐life were dependent upon the model used.

Peaks of in situ N₂O emissions are influenced by N₂O‐producing and reducing microbial communities across arable soils

Global Change Biology (2017)

Luiz A. Domeignoz‐Horta Laurent Philippot Céline Peyrard David Bru Marie‐Christine Breuil

Abstract Agriculture is the main source of terrestrial N 2 O emissions, a potent greenhouse gas and the main cause of ozone depletion. The reduction of N 2 O into N 2 by microorganisms carrying the nitrous oxide reductase gene ( nosZ ) is the only known biological process eliminating this greenhouse gas. Recent studies showed that a previously unknown clade of N 2 O‐reducers ( nos Z II ) was related to the potential capacity of the soil to act as a N 2 O sink. However, little is known about how this group responds to different agricultural practices. Here, we investigated how N 2 O‐producers and N 2 O‐reducers were affected by agricultural practices across a range of cropping systems in order to evaluate the consequences for N 2 O emissions. The abundance of both ammonia‐oxidizers and denitrifiers was quantified by real‐time qPCR , and the diversity of nosZ clades was determined by 454 pyrosequencing. Denitrification and nitrification potential activities as well as in situ N 2 O emissions were also assessed. Overall, greatest differences in microbial activity, diversity, and abundance were observed between sites rather than between agricultural practices at each site. To better understand the contribution of abiotic and biotic factors to the in situ N 2 O emissions, we subdivided more than 59,000 field measurements into fractions from low to high rates. We found that the low N 2 O emission rates were mainly explained by variation in soil properties (up to 59%), while the high rates were explained by variation in abundance and diversity of microbial communities (up to 68%). Notably, the diversity of the nos Z II clade but not of the nos Z I clade was important to explain the variation of in situ N 2 O emissions. Altogether, these results lay the foundation for a better understanding of the response of N 2 O‐reducing bacteria to agricultural practices and how it may ultimately affect N 2 O emissions.
