“…Additionally, our results would support other research addressing N losses and soil availability (Chantigny et al, 2002;Yang et al, 2002;Aita et al, 2012;Chalhoub et al, 2013) and the parametrization of mathematical models (e.g., CENTURY, RothC, DAISY, PASTIS) assessing changes on soil organic C stocks according to soil management and fertilization practices (Bruun et al, 2003;Yokozawa et al, 2010;Chalhoub et al, 2013;Cong et al, 2014). Future long-term studies assessing changes in soil organic C stocks due to soil tillage practices and organic fertilization should also address concomitant ammonia and greenhouse gases emissions (i.e., CH 4 and N 2 O) from these practices (Aita et al, 2014b) to fully evaluate the environmental benefit of recycling such wastes in agricultural systems.…”

A B S T R A C TAgriculture can be either a source or sink of atmospheric CO 2 depending on soil management. The application of swine slurry in conventional tilled soils could enhance soil CO 2 emission depleting soil organic C stocks. However, the use of recalcitrant C-rich organic fertilizers in no-till soils can offset soil CO 2 emission promoting soil C sequestration. This hypothesis was tested by evaluating short-term CO 2 -C emissions from a Rhodic Nitisol under contrasting soil disturbance levels (disturbed (DS) and undisturbed soil (US)) top-dressed with mineral or organic fertilizers (urea (UR), raw swine slurry (RS), anaerobically digested swine slurry (ADS), and composted swine slurry (CS)). Soil CO 2 emission was evaluated for 64 days using static chambers where gas samples were collected and analysed by photoacoustic infrared spectroscopy. Soil water-filled pore space (WFPS), temperature and meteorological data were concomitantly registered and a first-order exponential decay model was used to assess the decomposition of organic fertilizers and CO 2 emissions induced by soil disturbance. Soil CO 2 -C emission was correlated with soil temperature, while limiting soil aeration impaired CO 2 -C efflux when WFPS >0.6 cm 3 cm À3 . Disturbance increased soil CO 2 -C efflux (36.3 AE 2.2 kg CO 2 -C ha À1 day À1 ) in relation to US (33.3 AE 1.6 kg CO 2 -C ha À1 day À1 ). Extra labile C input through RS amendment induced an increased soil CO 2 -C efflux for a longer period (t 1/2 = 16.9 and 9.6 days in DS and US treatments, respectively), resulting in higher CO 2 -C emissions than soil amended with other fertilizers. The recalcitrant C input by ADS and CS had limited effect on soil CO 2 -C emissions. CS presented a genuine potential for substantial soil organic C accumulation while offsetting increased CO 2 -C emissions in comparison to RS amended soils.

“…Data analysis for N balance results that comprise the autumn period (s2-s3 and s1-s3) revealed no significant effects from any of the factors soil tillage, compost application and top mineral N dressing except that ANM s2-s3 tended to be higher if compost was applied on CT plots (p < 0.1). This may be interpreted as a sign that C sequestration by compost application will increase N availability through increase of soil organic N content and mineralization in the medium to long term as reported by Chalhoub et al (2013). Due to autumn application of stable compost in our experiment, N availability of the last application by biodegradation was probably low in the next growing season.…”

Soil organic nitrogen mineralization rates and possible predictors thereof were investigated for vegetable‐growing soils in Belgium. Soil organic matter (SOM) was fractionated into sand (> 53 μm) and silt+clay (< 53 μm) fractions. The latter fraction was further separated into 6%NaOCl‐oxidation labile (6%NaOCl‐ox) and resistant N and C and subsequently into 10%HF‐extractable (mineral bound) and resistant (recalcitrant) N and C. The N mineralization turnover rate (% of soil N/year) correlated with several of the investigated N or C fractions and stepwise linear regression confirmed that the 6%NaOCl‐ox N was the best predictor. However, the small R² (0.42) of the regression model suggests that soil parameters other than the soil fractions isolated here would be required to explain the significant residual variation in N mineralization rate. A next step could be to look for alternative SOM fractionations capable of isolating bioavailable N. However, it would appear that the observed relationships between N fractions and N mineralization may not be causal but indirect. The number of vegetable crops per rotation did not influence N mineralization, but it did influence 6%NaOCl‐ox N, probably as an effect of differences in crop residues returned and organic manure supply. However, the nature of this relation between management, SOM quality and N mineralization is not clear. Explanation of correlations between N mineralization and presumed bioavailable N fractions, like the 6%NaOCl‐ox N, requires further mechanistic elucidation of the N mineralization process.

The input of organic fertilizers into soils is an interesting option as a substitution for mineral fertilization, but how their interaction with crop residues affects the fate of added carbon (C) and nitrogen (N) in the soil is still poorly known. Therefore, we analysed the effect of adding together organic fertilizer and straw on subsequent C and N mineralization. We incubated sugarcane straw (S), pig slurry (PS) and solid sewage sludge (DS) separately and in mixtures (PS‐S and DS‐S) at 28°C during 182 days. To discuss interactions, we used a simple additivity model based on measurements and a mechanistic model for C and N transformations in soil (CANTIS). Both models overestimated the C mineralization and did not correctly predict N mineralization of the two mixtures. The differences between observed and expected values calculated with the models were negative for C mineralization, indicating an antagonistic interaction in mixtures. The limitations for C decomposition might be the result of many factors, such as negative priming effect or limitation in N accessibility, which are not considered by CANTIS. We assumed that the priming effect induced by the mineralization of a mixture was not significantly different from the priming effect induced by the mineralization of the organic matters incubated alone. The use of a contact factor in CANTIS allowed the predicted C and N kinetics for the mixtures to be correctly fitted to measured data. It reflects the effect of fine‐scale C and N distribution heterogeneities on the intensity of microbial decomposition. A better integration of the interactions between different N and C sources should be addressed to develop modelling as an accurate tool for agroecosystem management. Highlights Experimental data and modelling allowed assessment of effects of mixtures on C and N mineralization. Mineralization of the organic material mixture was not the sum of the mineralization of each material. A contact factor reflecting the N‐rich substrate accessibility was needed to predict C and N data. Pig slurry and sewage sludge mixed with straw showed antagonistic effects on mineralization.
