“…The low soil CH 4 uptake agrees with other studies carried out in East African maize fields that found upland agricultural soils to act predominantly as minor CH 4 sinks (Ortiz-Gonzalo et al, 2018;Pelster et al, 2017;Rosenstock et al, 2016). The low soil CH 4 consumption in the control plots could be because the limited C and N availability, due to years of no fertilizer application, can be detrimental to the methanotrophs (Bodelier et al, 2000;Subke et al, 2018). Furthermore, the control plots had the highest bulk density, which could have lowered the diffusion of CH 4 and O 2 from the atmosphere to the methanotrophic archaea in the soil (Castaldi et al, 2006;Konda et al, 2010).…”

“…Application of inorganic fertilizer may have enhanced CH 4 oxidation, similar to Nyamadzawo et al (2014) who noted that N application to sandy loam soils reduced CH 4 emissions. When N is applied as inorganic fertilizer in N-deficient conditions (Du et al, 2019), it relieves the N limitation of cell growth and subsequently increases the activity of methanotrophic microorganisms in the long term, increasing CH 4 uptake (Bodelier et al, 2000). Nitrogen application (either as ammonium or nitrate) also promotes the growth and activity of the nitrifying population, co-oxidizing atmospheric CH 4 thus increasing CH 4 uptake (Bodelier & Laanbroek, 2004;Reay et al, 2005).…”

In sub‐Saharan Africa (SSA), few studies have quantified greenhouse gas (GHG) emissions following application of soil amendments, for development of accurate national GHG inventories. Therefore, this study quantified soil GHG emissions using static chambers for two maize cropping seasons (one full year) of four different soil amendments in the central highlands of Kenya. The four treatments were (i) animal manure, (ii) inorganic fertilizer, (iii) combined animal manure and inorganic fertilizer, and (iv) a no‐N control (no amendment) laid out in a randomized complete block design. Cumulative annual soil fluxes (February 2017 to February 2018) ranged from −1.03 ± 0.19 kg CH4‐C ha−1 yr−1 from the manure inorganic fertilizer treatment to −0.09 ± 0.03 kg CH4‐C ha−1 yr−1 from the manure treatment, 1,391 ± 74 kg CO2‐C ha−1 yr−1 from the control treatment to 3,574 ± 113 kg CO2‐C ha−1 yr−1 from the manure treatment, and 0.13 ± 0.08 to 1.22 ± 0.12 kg N2O‐N ha−1 yr−1 in the control and manure treatments, respectively. Animal manure amendment produced the highest cumulative CO2 emissions (P < 0.001), N2O emissions (P < 0.001), and maize yields (P = 0.002) but the lowest N2O yield‐scaled emission (YSE) (0.5 g N2O–N kg−1 grain yield). Manure combined with inorganic fertilizer had the highest cumulative CH4 uptake (P < 0.001) and N2O YSE (2.2 g N2O–N kg−1 grain yield). Our results indicate that while the use of animal manure may increase total GHG emissions, the concurrent increase in maize yields results in reduced yield‐scaled GHG emissions.

“…In addition, nitrogen fertilizers are among the factors that regulate aerobic methane oxidation (31)(32)(33)(34) and CH 4 emission (35)(36)(37). Methanotrophs of both type I (Gammaproteobacteria) and type II (Alphaproteobacteria) are also able to fix atmospheric N 2 (38,39).…”

“…Addition of N fertilizer increased CH 4 emissions in rice soil due to the stimulation of methanogens by greater production of crop biomass under N fertilization (Banik et al 1996) and Shang et al 2011). In contrast, N fertilizer has also stimulated the activities of methanotrophs that resulted in greater CH 4 oxidation (Bodelier et al 2000a, b). Methane emission rate from ammonium sulfate treatment was the lowest, followed by ammonium chloride treatment, and then urea treatment (Kimura 1992).…”

An assessment of within field spatial variations in grain yield and methane (CH4) emission was conducted in lowland rice fields of Myanmar. Two successive rice fields (1st field and 2nd field) were divided into fertilized and non-fertilized parts and CH4 measurements were conducted at the inlet, middle and outlet positions of each field. The results showed that CH4 emissions at non-fertilized parts were higher than those at fertilized part in both rice fields. The average CH4 emissions ranged from 8.7 to 26.6 mg m-2 h-1 in all positions in both rice fields. The spatial variation in CH4 emission among the positions was high in both rice fields with the highest emissions in the outlet of the 1st field and the inlet of the 2nd field. The CH4 emissions at these two positions showed 2 - 2.5 times higher than those at other positions in both rice fields. Stepwise regression analysis indicates that soil total carbon content is the primary factor for CH4 emission. The average CH4 emissions during rice growing season were 13.5 mg m-2 h-1 for the 1st field and 15.7 mg m-2 h-1 for the 2nd field. Spearman rank order correlation analysis showed that CH4 emission was significantly and positively correlated with soil temperature, surface water depth and negatively correlated with soil redox potential. The result indicated that high within field spatial variation in CH4 emissions required different site specific management practices to mitigate CH4 emissions in lowland paddy rice soil.
