“…The positive effect of conservation tillage along with organic manure and residue retention/incorporation in increasing the TOC in paddy soils of India have also been reported [7,43,45,49]. Further, the integrated uses of organics with inorganic fertilizers also have been reported to enhance productivity and SOC concentration over that with the sole application of fertilizer or manure [35,50].…”

Over centuries and even today, traditional farming practices are well performed without any ecological degradation. However, management practice such as conservative tillage combined with nutrient and residue could increase the crop production as well as soil fertility. A three-year replicated study was conducted to assess the effects of agronomic modification of traditional farming practices on productivity and sustainability of rice (wet season)-rice (dry season) system (RRS). The replacement of farmers practice (T 2 ) with conservation effective tillage (no-till (NT)) and integrated nutrient management (INM) practice along with 30% residue retention (T 5 ) enhanced the straw, root and biomass yield of both wet season rice (WR), dry season rice (DR) and system as a whole over T 2 . Treatment T 5 recorded significantly lower soil bulk density ( b ) and higher pH than the T 2 after three years of the experiment. Further, treatment T 5 increased total soil organic carbon (2.8%), total soil organic carbon stock (2.8%), carbon sequestration rate (336.5 kg ha −1 year −1 ), cumulative carbon stock (142.9%) and carbon retention efficiency (141.0%) over T 2 of 0-20 cm depth after three year. The soil microbial biomass carbon concentration was significantly the highest under T 5 . Similarly, the dehydrogenase activity was the maximum under T 5 . Adoption of conservation tillage and nutrient management practice involving NT and INM along with residue retention can enhance the system productivity, and C and N sequestration in paddy soils is thereby contributing to the sustainability of the RRS.

“…Moreover, the grain quality is comparatively superior under INM, which is accompanied by high profitability, improving soil health and sustainability in a wheatsoybean system (Behera et al, 2007b). Nath et al (2011) indicate that INM has the potential to improve organic carbon, soil enzymes activities , microbial biomass carbon and bacterial populations. These changes in turn enlarge the nutrient pool of available N, P and K for plants' growth (A.…”

“…Lastly, farmers and researchers cannot neglect the role of the soil microorganisms in controlling nutrient conversions, solubility, availability, release from the soil root zone to plant roots, and also the role in absorption and raising nutrient-use efficiency, which can be achieved by following the INM system [8,[107][108][109][110][111][112]]. An additional trend was also observed, a decrease in the losses of water and nutrients through leaching, runoff, volatilization, emissions, and immobilization [23], which resulted from an increase in the soil organic matter contents and improvement of soil physical and hydrological properties.…”

Alleviation of poverty and achievement of zero-hunger target and food security are significant challenges faced by agricultural planners worldwide. Improving many agronomic approaches, which have drastic effects on crop growth and yield, is urgently needed to report this aim. Replacement of a part of chemical fertilizers by organic manure through a simple technique of using minimum effective dose of sufficient and balanced quantities of organic and inorganic fertilizers in combination with specific microorganisms, called INM, has a bright solution in this area. Recently, several investigators reported that integrated use of chemical fertilizers with organic manure is becoming a quite promising practice not only for maintaining higher productivity but also for greater stability to crop production. In addition, INM acts as a source of energy, organic carbon, and available nitrogen for the growth of soil microbes and improvement of physical properties of soil, and also have great residual effect on subsequent crops. So, the key component of the INM goal is to reach the eco-friendly practice through the harmonious properties of both sources by making a combination that can be used for decreasing the enormous use of chemical fertilizers and accreting a balance between fertilizer inputs and crop nutrient requirement, maintaining the soil fertility, optimizing the level of yield, maximizing the profitability, and subsequently reducing the environmental pollution. Lastly, INM is a tool that can offer good options and economic choices to supply plants with a sufficient amount of nutrients in need and can also reduce total costs, create favorable soil physiochemical conditions and healthy environment, eliminate the constraints, safeguard the soil nutrient balance, and find safety methods to get rid of agriculture wastes.
