“…In general, in the first season, the microbial populations were higher when compared to second season. Similar reports of increased microbial population with fly ash application has been reported by Ramteke et al (2017) in rice-wheat cropping system and Sheoran et al (2014). These results might be due to the fact that applied organic sources were able to get mineralized rapidly and consequently provided sufficient nutrition for the proliferation of microbes and their activities in terms of soil enzymes.…”

Investigations were carried out to study the influence of flyash seed pelleting on microbial populations of bacteria, fungi, actinomycetes, and rhizobium in black gram and green gram. The experimental results revealed that seed pelleting with fly ash seed pelleting @ 250 g with rice gruel as adhesive increased rhizobium population in black gram and fungi and actinomyctes population in green gram by 10 to 15 %. Increased microbial activity will enrich soil microflora and in turn will be helpful in increasing the crop yield.

“…Moreover, soil microbial population also increased with addition of 10% (w/w) FA in soil which in turn positively influenced soil enzyme activity and soil biomass (Kohli and Goyal 2010). Similar results were found with the field experiment carried out by Ramteke et al (2017) which reported that incorporation of appropriate amount of FA along with manures (FYM) and fertilizers (NPK) has enhanced soil microbial population as well as enzymatic activity in rice-wheat cropping system alfisols and versitols. Another study reported maximum grain yield and soil dehydrogenase activity on combined application of lime+ FA+ FYM in relation to control treatment.…”

Fly ash (FA), solid waste residue, is a by-product of thermal power plant, and its disposal is considered to be the current biggest challenge faced by the entire world. Various studies have revealed that addition of FA to the soil may improve the physical, chemical, and biological properties of soil mixture. FA is also considered to provide readily available soil micro-and macronutrients. Lower doses of FA enhance the nutritional status of agricultural soil, thereby promoting plant growth, whereas higher doses of FA result in heavy metal pollution leading to deleterious effects which hinder the soil microbial communities and related enzymatic activity. Practically, FA is utilized in agriculture due to its usage as "ecofriendly and costeffective" soil/fertilizer amendment which depends upon various factors like soil types, climatic conditions, plant selected for growth, etc. However, combined biotechnological approaches (organic and inorganic) need to be applied to soil-FA mixtures in order to reduce the amount of toxic elements present in FA and also to maintain the nutrient status as well as soil microbial activity. Overall, the lower doses of FA application could be utilized to revamp the soil structure, soil microflora, N-cycling process, and enzymatic activity which have a significant role in promoting the growth of plants.

“…Nayak et al (2007) similarly demonstrated enhanced dehydrogenase activity with both compost and inorganic fertilizer application under continuous ricegrowing situations and explained a significant relationship between SMBC. The addition of fly ash and FYM to a rice-wheat cropping system in Alfisol and Vertisol significantly enhanced the microbial biomass carbon and dehydrogenase activity in soil (Ramteke et al, 2017). Kanchikerimath and Singh (2001) found that the inorganic fertilizer (NPK) increased crop yield, SOC, total N, mineralizable C and N, microbial biomass C and N, and dehydrogenase, urease, and alkaline phosphatase activities, while manure applied together with inorganic fertilizer increased these parameters more strongly.…”

“…Similar, observations were also made by Singh et al (2009) where the addition of inorganic fertilizers with various organic manures in rice-wheat system enhanced the soil particle aggregation which in turn resulted in higher storage of soil organic carbon content. For instance, several studies conducted in India to know the effect of integrated nutrient supply on soil organic carbon status indicated significant gain in soil organic carbon, especially under intensive cropping systems like rice-wheat (Singh et al, 2000;Nayak et al, 2012;Ramteke et al, 2017), maize-wheat (Paramesh et al, 2014(Paramesh et al, , 2020, maize-mustard (Saha et al, 2010;Moharana et al, 2012), and rice-groundnut (Prasad et al, 2002; Table 3).…”

Recently, most agrarian countries have witnessed either declining or stagnant crop yields. Inadequate soil organic matter (SOM) due to the poor physical, chemical, and biological properties of the soil leads to an overall decline in the productivity of farmlands. Therefore, the adoption of integrated nutrient management (INM) practices is vital to revive sustainable soil health without compromising yield potential. Integrated nutrient management is a modified nutrient management technique with multifarious benefits, wherein a combination of all possible sources of plant nutrients is used in a crop nutrition package. Several studies conducted in various parts of the world have demonstrated the benefits of INM in terms of steep gain in soil health and crop yields and at the same time, reducing greenhouse gas emissions and other related problems. The INM practice in the cropped fields showed a 1,355% reduction in methane over conventional nutrient management. The increase in crop yields due to the adoption of INM over conventional nutrient management was as high as 1.3% to 66.5% across the major cropping systems. Owing to the integration of organic manure and residue retention in INM, there is a possibility of significant improvement in soil aggregates and microbiota. Furthermore, most studies conducted to determine the impact of INM on soil health indicated a significant increase in overall soil health, with lower bulk density, higher porosity, and water-holding capacity. Overall, practicing INM would enhance soil health and crop productivity, in addition to decreasing environmental pollution, greenhouse gas emissions, and production costs.
