“…The commercial history of microbial biofertilizers was launched with the Rhizobium-based bioinoculant named "Nitrogin, " which was considered the pioneer biofertilizer of all rhizobial inoculants (Patil and Solanki, 2016). Exploring the plant growth promoting abilities of soil N 2 -fixing microorganisms (including nonsymbiotic bacteria such as Azotobacter) led to the development of the Azotobacter-based biofertilizer namely "azotobakterin" in Russia and East European countries, where 10 million ha of land was treated with microbial formulations in the middle of 19th century (Brown, 1974;Rovira, 1991).…”

Biological nitrogen fixation (BNF) refers to a microbial mediated process based upon an enzymatic “Nitrogenase” conversion of atmospheric nitrogen (N2) into ammonium readily absorbable by roots. N2-fixing microorganisms collectively termed as “diazotrophs” are able to fix biologically N2 in association with plant roots. Specifically, the symbiotic rhizobacteria induce structural and physiological modifications of bacterial cells and plant roots into specialized structures called nodules. Other N2-fixing bacteria are free-living fixers that are highly diverse and globally widespread in cropland. They represent key natural source of nitrogen (N) in natural and agricultural ecosystems lacking symbiotic N fixation (SNF). In this review, the importance of Azotobacter species was highlighted as both important free-living N2-fixing bacteria and potential bacterial biofertilizer with proven efficacy for plant nutrition and biological soil fertility. In addition, we described Azotobacter beneficial plant promoting traits (e.g., nutrient use efficiency, protection against phytopathogens, phytohormone biosynthesis, etc.). We shed light also on the agronomic features of Azotobacter that are likely an effective component of integrated plant nutrition strategy, which contributes positively to sustainable agricultural production. We pointed out Azotobacter based-biofertilizers, which possess unique characteristics such as cyst formation conferring resistance to environmental stresses. Such beneficial traits can be explored profoundly for the utmost aim to research and develop specific formulations based on inoculant Azotobacter cysts. Furthermore, Azotobacter species still need to be wisely exploited in order to address specific agricultural challenges (e.g., nutrient deficiencies, biotic and abiotic constraints) taking into consideration several variables including their biological functions, synergies and multi-trophic interactions, and biogeography and abundance distribution.

“…Then, it took less than 10 years before beneficial microorganisms are used as bioinoculants by Nobbe and Hiltner (1896) . They patented what may be considered the pioneer product of all rhizobial inoculants ( Patil and Solanki, 2016 ), launching the commercial history of microbial biofertilizers with a Rhizobium -based bioinoculant named “Nitrogin.” Since then, scientists from academic and private research institutions have been exploring the NF abilities of microorganisms such as Azotobacter and then the cyanobacteria in promoting growth of large number of plants. A few decades later, two mainly microbial based products namely “azotobakterin” and “phosphobacterin” based on Azotobacter chroococcum (NF) and Bacillus megaterium (PSB) were used in Russia and East European countries.…”

Soil Microbial Resources for Improving Fertilizers Efficiency in an Integrated Plant Nutrient Management System

Tomorrow’s agriculture, challenged by increasing global demand for food, scarcity of arable lands, and resources alongside multiple environment pressures, needs to be managed smartly through sustainable and eco-efficient approaches. Modern agriculture has to be more productive, sustainable, and environmentally friendly. While macronutrients such as nitrogen (N), phosphorus (P), potassium (K), and sulfur (S) supplied by mineral fertilizers are vital to crop production, agriculturally beneficial microorganisms may also contribute directly (i.e., biological N2 fixation, P solubilization, and phytohormone production, etc.) or indirectly (i.e., antimicrobial compounds biosynthesis and elicitation of induced systemic resistance, etc.) to crop improvement and fertilizers efficiency. Microbial-based bioformulations that increase plant performance are greatly needed, and in particular bioformulations that exhibit complementary and synergistic effects with mineral fertilization. Such an integrated soil fertility management strategy has been demonstrated through several controlled and non-controlled experiments, but more efforts have to be made in order to thoroughly understand the multiple functions of beneficial microorganisms within the soil microbial community itself and in interaction with plants and mineral resources. In fact, the combined usage of microbial [i.e., beneficial microorganisms: N2-fixing (NF), P-solubilizing, and P mobilizing, etc.] and mineral resources is an emerging research area that aims to design and develop efficient microbial formulations which are highly compatible with mineral inputs, with positive impacts on both crops and environment. This novel approach is likely to be of a global interest, especially in most N- and P-deficient agro-ecosystems. In this review, we report on the importance of NF bacteria and P solubilizing/mobilizing microbes as well as their interactions with mineral P fertilization in improving crop productivity and fertilizers efficiency. In addition, we shed light on the interactive and synergistic effects that may occur within multi-trophic interactions involving those two microbial groups and positive consequences on plant mineral uptake, crop productivity, and resiliency to environmental constraints. Improving use of mineral nutrients is a must to securing higher yield and productivity in a sustainable manner, therefore continuously designing, developing and testing innovative integrated plant nutrient management systems based on relevant biological resources (crops and microorganisms) is highly required.

“…Proper timing and strict procedures of application are very essential as excessive heat or desiccation may reduce the inoculant efficiency. The producer recommended storage conditions should be strictly followed [48]. Poor agronomic practices, the presence of pollutants, and numerous exudates from the plant roots may hinder the effectiveness of microbial inoculant on the soil.…”

The Use of Microbial Inoculants in Crop Production for Food Security Sustainability

Increasing human population, war, climate change, herdsmen-farmers clashes, banditry, terrorism, political unrest affected crop production negatively. These factors widen the gap between food production supply and its demand. In an attempt to fill this gap, agrochemicals were used to increase crop yield to meet the food demand of the ever-increasing population. Agrochemical’s introduction was accepted initially due to their quick and nonspecific actions. Decades later, these agrochemicals begin to pose threats to human and livestock health, causing land degradation, ecosystem imbalance, reduction in soil fertility and productivity. To avert the negative effects of agrochemicals on food and feed products, soil, water quality, and the environment. The use of a safe and eco-friendly alternative was developed. Microbial inoculants serve to be the best substitute for agrochemicals with substantial benefits in sustainable crop production and environmental sustainability. This review aims at updating available information on the benefits of using microbial inoculants in boosting crop production and the strategies to adopt for its effectiveness.
