“…Understanding the contributions of organic amendments in CS is important for the estimation of CS, their nutrient supply potential and their role in it. In different organic amendments, poultry manure is found to be more efficient in increasing C and other nutrients in soils and microbial activities which contribute to CS in the rice-rice cropping system [63,64].

Carbon sequestration (CS) is an important strategy for the mitigation of climate change (CC) as well as for improving the soil fertility of agricultural soils. Carbon sequestration in crop lands and rangelands requires a certain amount of organic matter (OM) presence in the soil called soil organic matter (SOM). Organic amendments like animal and poultry manures, the incorporation of different crop residues, different types of compost, sugarcane bagasse, peat soils, different wood chips, biochar and good agricultural practices like cover crops, nutrient management, mulching, zero and no-tillage techniques, soil biota management and mulching are effectively used for this purpose. These enhance the SOM and improve the soil's physical and chemical properties which help to sequester more C in soil which ultimately contributes towards CS and CC mitigation.

“…Microorganisms are a key factor in nutrient cycling; therefore, probing the relationships between the microbial community of paddy soil, their functional activity and plant nutrient dynamics has been an active topic of research in recent years. For example, the potential for carbon decomposition and nitrogen mineralization of paddy soil was found to be strongly correlated with the soil organic carbon and total N contents in a Japanese soil (Chen et al ., ). Balanced fertilizer application in paddy fields increased the microbial functionality in P‐limited paddy soil (Su et al ., ).…”

Until recently, the relation between the microbial community structure and paddy soil enzyme functions has not been clear. Two types of paddy soil, located only 2 km apart and involved in the same field experiment, were used. We found a clear spatial effect on the bacterial community structure that could be related to the types of soil. The bacterial community structure was linked statistically to four indices of soil enzyme activity involving Gram‐positive and Gram‐negative bacterial phospholipid fatty acids (PLFAs), suggesting that the bacterial community has a more important role than fungi and other eukaryotes in modulating enzyme function in paddy soil. Redundancy analysis also showed that the two soil bacterial communities regulated soil enzyme activity with different effects. The α‐diversity of the bacterial community was positively associated with invertase activity, and negatively associated with the biomass normalized urease and arylsulphatase activities. In addition, the differences in soil enzyme activities were closely linked to dominant optimal taxonomic units (OTUs), most of which were phylogenetically related to enzyme producers from Planctomycetes, Proteobacteria and Chloroflexi with different 16S rRNA gene sequence similarity levels. Our results suggested that the enzyme function of paddy soil was linked to both the diversity and composition of bacteria in this study. Highlights We quantified the relation between the soil enzyme functions and bacterial community. Enzyme activities of paddy soil correlated with G+ and G− PLFAs. Bacterial α‐diversity was correlated statistically with paddy soil enzyme function. Species of Planctomycetes, Proteobacteria and Chloroflexi comprised the primary enzyme regulators.

“…Rice paddy fields are considered as one of the most important sources of CH 4 . During the past decades, there were many studies carried out around the world, especially in Japan to understand the CH 4 dynamics in rice paddies (Yagi and Minami 1990;Watanabe and Kimura 1998;Inubushi et al 2003;Cheng et al 2008;Itoh et al 2011;Hayano et al 2013;Win et al 2016;Cheng et al 2016;Nakajima et al 2016). It is well known that there are different CH 4 emission potentials among different rice varieties (Huang et al 1997;Wassmann and Aulakh 2000;Yao et al 2000;Aulakh et al 2002;Jia et al 2006;Lou et al 2008;Gutierreza et al 2013;Zhang et al 2015).…”

To determine methane (CH 4) emission differences between edible and forage rice cultivars, we conducted a pot experiment in Yamagata, Japan to grow edible rice Haenuki, and forage rice Fukuhibiki (for feed rice) and Tachisuzuka (for whole-crop silage (WCS) rice) under similar soil and meteorological conditions. The total amounts of N, P, and K fertilizers applied for Fukuhibiki and Tachisuzuka were 1.7, 1.3, and 1.3 times, respectively, higher than those of Haenuki. CH 4 fluxes, and rice plant night respirations were measured once weekly or fortnightly. As per the results, for the whole growth period, shoot height, maximum and productive tiller numbers, and plant biomass were significantly different among the three rice varieties. The rice growth period for Haenuki and Fukuhibiki was 107 days after transplanting (DAT), while that for Tachisuzuka was 135 DAT. The highest peak of CH 4 flux occurred around the heading stage for the three varieties. Consistently significant (P < 0.05) or obvious (P < 0.1) positive correlations between CH 4 flux and night respiration among the varieties were observed from 9 weeks after rice transplanting to harvest, indicating that much of the CH 4 flux was from newly produced root exudates and plant debris through plant photosynthesis. The cumulated CH 4 emissions during the same growth period, 106 DAT, from Haenuki, Fukuhibiki, and Tachisuzuka were 55.36, 77.46, and 78.40 g C m −2 , respectively. Additionally, Tachisuzuka emitted 25.11 g C m −2 more CH 4 between 106-134 DAT. The final cumulated CH 4 emissions from Fukuhibiki and Tachisuzuka were 39.9% and 87.0% higher than that from Haenuki, respectively, throughout their growth period.
