“…In our study, the interannual differences in SOM increased in a relatively stable trend, likely because the changes in soil organic content were usually insensitive to the current management methods. Changes mainly occurred when smaller quantities of crop residues were incorporated into the soil [41]. Similarly, Yadav et al [23] and Mi et al [24] concluded that SOM significantly improved with the incorporation of straw into the soil profile at depths of 0-40 cm under RWR system.…”

Soil management practices are used to enhance soil organic carbon, fertility, and crop productivity around the world. However, accurate information about the appropriate amount of straw incorporation is not available, because it is generally believed that at least 30% of the soil surface should be covered by straw, which is not implemented in all field environments. Therefore, a two-year (2016-2017) field experiment was conducted to investigate the impact of different percentages of straw incorporation and tillage methods, i.e., reduced tillage (RT) and conventional tillage (CT), on crop yield, soil organic carbon (SOC), total nitrogen (TN), and soil carbon storage (SCS) in rice-wheat cropping systems, under eight treatments. The experimental results showed that the greatest reduction in soil dry bulk density (ρ b ) was found under CT with 100% straw coverage (9.79%), whereas the least reduction occurred under CT with no straw (1.31%). The mean TN concentration, soil organic matter (SOM), and soil carbon storage (SCS) were significantly higher by 0.98 g/kg, 17.07%, and 14.20%, respectively, under reduced tillage with 60% straw incorporation (RTsi 60 ) compared with all other treatments. Our findings demonstrate that the incorporated wheat residues resulted in the highest rice production (7.95-8.63 t/ha) under RTsi 60 . We recommend the adoption of reduced tillage with 60% straw incorporation to increase rice yield, improve soil structure, and enhance TN, SOM, and SCS in paddy soil under rice-wheat rotation fields for agricultural sustainability.

“…Organic fertilizers are rich in nutrients mainly derived from animal manure and crop straws, which are agricultural waste [6,7]. It has been demonstrated that soil's physicochemical properties can be modified by organic fertilizer as a result of its comprehensive nutrients [8,9]. Moreover, the fertilizer efficiency of organic factors is more lasting when compared with under aerobic conditions, which can be absorbed by crops [23,24].…”

As a fundamental part of the soil ecosystem, prokaryotes are involved in the preservation of soil functions. However, little is known of how the combined application of long-term organic and inorganic nitrogen fertilizer affects the prokaryotic communities’ dynamics at a paddy field. A long-term positioning experiment initiated in 2013 with four treatments (NO: no N fertilizer, CN: 100% urea N with no organic fertilizer, PM: 80% urea N plus 20% N with pig manure, CM: 80% urea N plus 20% N with compost) were applied to detect the differential responses of soil physicochemical properties, and prokaryotic community structure and composition in different fertilization regimes. The results indicated that the long-term combined application of organic and inorganic nitrogen fertilizers altered the physicochemical properties to some extent and, simultaneously, established unique prokaryotic communities. In detail, the treatment of PM and CM significantly increased the content of soil organic carbon (SOC) and total nitrogen (TN) compared to NO. Moreover, a total of 31 indicator taxa were screened across the four treatments by LDA Effect Size (LEfSe) analysis following the principle of the greatest differences, which suggests that these indicator taxa were more sensitive to the fertilization. This research suggested that the combined application of long-term organic and inorganic nitrogen fertilizers not only contributed to the soil’s physicochemical properties but also changed the prokaryotic community composition.

“…Organic wastes, which are used as soil additives constitute a source of energy for microorganisms, and also cause changes in their diversity and activity [21,22]. An assessment of the effect EOM additives on soil microbiome diversity may be performed on the basis of genetic, metabolic and enzymatic activity assays [19,23] the results of which may be used as an indicator of the shifts that occur due to the influence of applied waste [24,25]. Unfortunately, the use of organic waste as a soil fertilizer also carries a certain risk as well as producing significant benefits.…”

Genetic and Metabolic Diversity of Soil Microbiome in Response to Exogenous Organic Matter Amendments

Loss of organic matter content of cultivated soils is observed in many regions of Europe. The possibility of using organic waste as a soil additive that enriches the soil with organic matter and essential components is important in soil quality protection and waste management. This research concerned the influence of six organic wastes—two industrial composts, three digestates and meat bone meal—on soil microbial properties. The study of functional microbial diversity concerns the determination of the catabolic capacity of bacterial, fungal and anaerobic communities in relation to carbon substrates in metabolic profiling plates (Biolog® ECO, FF, AN (Biolog Inc., Hayward, CA, USA)). The assessment of genetic diversity was made on the basis of analysis of the restriction profile of ammonia-oxidizing archaea. Additionally, soil dehydrogenases activity was determined. The research showed that the type of organic waste used had an influence on the microbiological parameters. The application of exogenous organic matter caused increases in functional and genetic microbial diversity. The nature of the noted changes was short term and periodic. The values of the microbiological parameters in soils with organic waste were similar to those of the control samples. This indicates an improved microbiological balance and stability of the soil environment after the application of exogenous organic matter.
