Nitrification inhibitors show potential to improve efficiency of fertilizer N use by keeping N in the ammonium form, decreasing leaching, and denitrification. The objective of this study was to evaluate the effectiveness of ammonium thiosulfate (ATS) and potassium thiosulfate (KTS) products to inhibit nitrification in three soils: Marvyn loamy sand, Tujunga loamy sand, and Sable silt loam. Two runs of a 10-week incubation experiment were performed, and soil ammonium-N (NH₄⁺-N), nitrite-N (NO₂⁻-N), and nitrate-N (NO₃⁻-N) concentrations were measured to determine the effectiveness of two rates of ATS and KTS (3.54:1 and 7.68:1 N:S ratio) to inhibit nitrification of urea-based fertilizers compared to an untreated control, urea, urea + ammonium sulfate, and urea + dicyandiamide (DCD) treatments. The higher rate of ATS and KTS reduced nitrification by 75% compared to untreated urea from day 14 to 63 in the Tujunga loamy sand in the first run and by 80% from day 21 to 56 in run two. Similarly, the higher rate of ATS and KTS reduced nitrification by 40% compared to urea for the Sable silt loam in run one from day 42 to 70. No treatments reduced nitrification compared to untreated urea in the Marvyn loamy sand. Nitrite-N concentrations followed similar trends when compared to NO₃⁻-N in the Tujunga soil, suggesting that the treatments inhibiting nitrification are inhibiting the first step in the nitrification process.

However, extended periods of reduced tillage can stratify phosphorus (P) in surface soil layers, which can have negative implications for both water quality and crop nutrition. We measured soil P stratification in a long-term (12-year) experiment under maize (<i>Zea mays</i>)–soybean (<i>Glycine max</i>) rotations that combine two tillage practices (chisel-plow, no-tillage) with/without a winter cover crop (<i>Secale cereale</i> or cereal rye). Our objectives were twofold: (1) to quantify soil P stratification in this 2 × 2 factorial experiment using a common P stratification index (P_strat) on six soil P measurements—water-extractable (H₂O-P), microbial biomass (MBP), anion exchange resin extractable phosphorus (AER-P), soil test Mehlich-3 P (STP), bicarbonate extractable phosphorus, and total P. We calculated P_strat as mean P concentrations at 0–5 cm divided by 5–25 cm depths and (2) to correlate P_strat to crop P uptake and yield to answer the question—Does P stratification limit crop growth? The P_strat ranged from 1.3 to 87.5 across all soil P measurements, but H₂O-P was most stratified (mean H₂O-P_strat = 22.8). No-tillage increased P_strat by 8%–584% compared to chisel plowing, and cover crops (with tillage) increased P_strat by 8%–269% compared to winter fallow with tillage. In an unexpected antagonistic interaction, however, adding a cover crop to no-tilled soils reduced P_strat by 23%–72% compared to no-till. Interestingly, soybean P uptake and yield were positively related to a few P_strat measures (<i>r</i> &gt; 0.48); but maize P uptake was negatively related to stratification of STP (<i>r</i> &lt; −0.46). We confirmed that long-term no-tillage, and even cover crops alone, can stratify soil P.

A control (CK; without biochar) and four biochar types, including one pristine biochar (PB) and three types of NB (NB1, NB2, and NB3), were applied at two rates (20 t ha⁻¹ [L1] and 40 t ha⁻¹ [L2]). Biochar types and application levels significantly influenced CH₄ and CO₂ emissions. NB effectively reduced CH₄ while increased CO₂ emissions in both soil types. NB enhanced the SOC pools, which is primarily attributed to increased mineral-associated and particulate SOC in both sandy and loamy soils. β-glucosidase, cellobiohydrolase, and β-xylosidase were significantly enhanced by NB, particularly at a higher application rate of biochar (L2) compared to CK, with more pronounced increases in loamy soil.

To clarify this issue, a field study was undertaken to evaluate the influence of three nitrogen fertilization rates (140, 180, and 220 kg N ha⁻¹) on N₂O emissions and grain corn (<i>Zea mays</i> L.) yield from sandy loam and silty clay soil field sites situated in southwestern Quebec, Canada. Crop nitrogen uptake and yields were greater on the sandy loam than on the silty clay. Grain yields increased with N fertilization rate. Cumulative N₂O emissions from the sandy loam soil were up to threefold greater than those from the silty clay soil due to soil and weather conditions during fertilizer application. No significant differences were found in the N₂O fluxes among the N rate treatments in either soil. Assessing results from five other studies, we found that under corn production, overall yield-scaled emissions from poorly drained soils were fivefold greater than well-drained (coarse- and medium-textured) soils.

Rock-Eval (RE) thermal analysis, which emerged as a major tool in soil science over the last few decades, has its advantages over other analytical methods, but it also has its limitations, particularly for studying soils with low SOC contents. Here, we propose a new thermal oxidative method with the REdevice to quantify low levels of SOC in calcareous soils: Oxypure. We analyzed soils using both the standard protocol of RE thermal analysis (RE650) and dry combustion using an elemental analyzer (EA) and compared them with the Oxypure method. Our results show that the RE650 protocol is inadequate for studying calcareous soils with low SOC content. Compared to the reference method EA, the Oxypure method is more suitable for quantifying SIC and SOC in calcareous soils with low SOC contents. This study also shows that SOC can be characterized from a combined C–CO₂ thermogram obtained using the Oxypure method.
