How do methane rates vary with soil moisture and compaction, N compound and rate, and dung addition in a tropical soil?
Open accessAbstract
Soil moisture and compaction, and source of N and bovine urine can reduce methane (CH 4 ) rates from agricultural soils. However, the magnitude of the effect is unknown in tropical soil under different conditions, as well as the potential of different urine-N concentration, volume, and sources of N in such an effect. This study aimed to investigate the effects of different soil conditions (moist, dry, compacted, moist-dung, moist-dung-compacted), N concentration in urine (2.5, 5.0, 10.0, and 15.0 g N L -1 ), volume of urine (25, 50, 100, and 200 ml kg -1 dry soil), and source of N (ammonium, nitrate, and urea) on CH 4 emissions. A tropical Ferralsol soil from marandu-grass pasture was incubated during 106 days and the CH 4 concentration determined by gas chromatography. The CH 4 rates varied significantly according to the soil conditions when manipulated the urine-N (p 4 m -2 h -1 for the moist, dry, compacted, moist-dung, and moist-dung-compacted soil, respectively, and, not responded to the level of N (p = 0.73) averaging 2.57 μg C-CH 4 m -2 h -1 . When evaluated, the volumes of urine cumulative CH 4 averages were - 0.52, - 1.24, - 0.88, 14.48, and 18.56 μg C-CH 4 m -2 h -1 for the moist, dry, compacted, moist-dung, and moist-dung-compacted, respectively. Soils were affected by soil treatments (p 4 rates (p = 0.1) averaging 0.88, - 1.26, and - 1.19 μg C-CH 4 m -2 h -1 respectively, for urea, nitrate, and ammonium. The CH 4 fluxes in tropical Ferralsols are controlled by the…

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
