“…However, it is worth remembering that legumes themselves can lead to significant nitrogen leaching when crop residues are mineralized; thus, agronomic practices such as reduction of tillage and using cover crops must also be considered to solve these environmental issues [204]. Commercially available bioinoculants for non-legumes uses plant growth-promoting rhizobacteria, but the efficiency of these products in incorporating fixed nitrogen is still limited and variable depending on the environment (for an extensive review see [205]). Azospirillum is a versatile inoculant because it not only fixes nitrogen but also mineralizes nutrients from the soil and sequesters iron [206] (for a more comprehensive review see [207]).…”

Nitrogen is an essential element of life, and nitrogen availability often limits crop yields. Since the Green Revolution, massive amounts of synthetic nitrogen fertilizers have been produced from atmospheric nitrogen and natural gas, threatening the sustainability of global food production and degrading the environment. There is a need for alternative means of bringing nitrogen to crops, and taking greater advantage of biological nitrogen fixation seems a logical option. Legumes are used in most cropping systems around the world because of the nitrogen-fixing symbiosis with rhizobia. However, the world's three major cereal crops—rice, wheat, and maize—do not associate with rhizobia. In this review, we will survey how genetic approaches in rhizobia and their legume hosts allowed tremendous progress in understanding the molecular mechanisms controlling root nodule symbioses, and how this knowledge paves the way for engineering such associations in non-legume crops. We will also discuss challenges in bringing these systems into the field and how they can be surmounted by interdisciplinary collaborations between synthetic biologists, microbiologists, plant biologists, breeders, agronomists, and policymakers.

“…Mikroba memiliki kemampuan melarutkan fosfat dalam tanah dan memfiksasi N2. Mekanisme yang terjadi pada mikroba pelarut fosfat meliputi sekresi asam organik dan enzim ekstraseluler fosfatase (Vandana et al 2017). Fiksasi N2 adalah salah satu komponen penting dalam input hara di tanah sawah (Dobermann dan Fairhurst 2000), sehingga bakteri pemfiksasi nitrogen sangat penting diberikan pada tanah sawah untuk meningkatkan ketersediaan unsur hara N.…”

The condition of unfertile paddy field due to excessive inorganic fertilizer application causing soil degradation. Fertilizing techniques using phosphate solubilizing and nitrogen fixer bacteria are breakthroughs that should be developed in paddy cultivation to increase fertility soil and harvest of rice. This research aims to study on phosphate solubilizing and nitrogen fixer bacteria ability to increase the harvest of rice by increasing chemical and biological fertility of soil. The research was conducted in the greenhouse of Sawah Baru experimental garden, IPB University. The design used was a completely randomized design with one factor that was dosage of inorganic fertilizers (NPK) with seven levels that were control, NPK 100%, NPK 0% + bacteria, NPK 25% + bacteria, NPK 50% + bacteria, NPK 75% + bacteria and NPK 100% + bacteria. Each stage was repeated four times, so there were 28 units. The results of phosphate solubilizing and nitrogen fixer bacteria could produce more rice grain 0.32 ton.ha<sup>-1</sup> than NPK 100% (recommended dose). Biological soil fertility improved with the increased population of bacteria, but there was no improved soil chemical fertility of soil.

“…As an alternative to commercial fertilizers, a series of biofertilization techniques had been developed, like composting use, organic and biological fertilizers, all of them aiming to promote sustainable agricultural practices favorable to the environment and that generate higher nutritional quality products (Vandana et al, 2017;Helmy, 2018). Biofertilizers are substances that contain alive microorganisms and improve the plant's development.…”

“…Owing to its ion retention capacity, OM preserves nitrogen, and phosphorus by diminishing these nutrients leaching, and favors microorganisms root colonization and prevents phytopathogens development (Lehman et al, 2015). Therefore, microbial inoculants have been used in sustainable agriculture to maintain high productivity and crop quality with lower costs compared to chemical fertilizers (Sarma et al, 2015;Li et al, 2017;Vandana et al, 2017).…”

Chlorophyta and Cyanophyta are photosynthetic organisms characterized by their biochemical plasticity, which has allowed them to develop in different environments and have a faster growth rate than plants. Depending on the species and environmental conditions, these organisms can produce nitrogenous enzymes, for atmospheric nitrogen fixation; phosphatases, that solubilize phosphorus; phytohormones, that promote plant growth; and hygroscopic polysaccharides, that prevent erosion and improve soil characteristics. In this sense, the aim of this review was to analyze the available information on the use of Chlorophyta and Cyanophyta as biofertilizers and their potential application in organic food production. Multiple studies and researches were found demonstrating the advantages of these microorganisms when being used to improve plants productivity, and also at the same time, leading to sustainable agriculture that is respectful to the environment. However, their high production cost has become a limiting factor for their commercialization.
