Microbial organic fertilizers have huge potential to improve agriculture sustainability and food security. Soils can be supplemented with high rates for microbial P, N, and S cycling. This means that microbial strains from these soils must be able to provide useful metabolic attributes for increasing plant nutrition. Microbial fertilizers promote plant growth and development by multiple mechanisms and processes and help to improve growth by enhancing plant nutrition and fighting against stresses.
The Rhizobia strains obtained from N-fertilized soils showed a lower capacity for promoting plant growth than strains taken from unfertilized areas. This indicates that the management history at the site may affect the degree of mutualism of the isolate. These strains can be used to make microbial biofertilizer, microbial organic fertilizer, bacterial inoculant fertilizer, microbiological fertilizer, and microorganisms fertilizers.
Studies have reported that the use of bacterial strains for improved phosphorus and sulfur solubility can greatly improve crop growth and yield. Functional assays including enzyme measurements and growth in minimal media confirmed that strains from low SO42- soils have several mechanisms for polymerizing organic-S.
These results indicate that research programs that seek “elite” microbes that can boost plant nutrition should start with inocula derived from areas that support plant-soil feedbacks like organic farms and unfertilized earth.
Soil Fertility Improvement by Using Microbial Organic Fertilizer
Soil fertility, the nutritional quality of plant-based food, and food security are greatly threatened due to climate change, global warming, the shift of agricultural practices, industrialization, and urbanization. There is a need to find innovative agro-inputs to allow agriculture to adapt to changing environmental conditions.
Exploiting microbial resources is one promising way to accomplish this goal. Microbial-based inoculants (a sub-category of biostimulants) have emerged as a popular agro-input for sustainable intensification, particularly for smallholders. The market share of biostimulants has grown significantly because of the broad know-how gained over the past two decades and the use of low-cost technologies to produce them.
Despite all of the above scientific evidence of their effectiveness, it is still necessary to make these commodities fully-fledged commodities that can be used by farmers for sustainable agriculture.
There are different types of biostimulants and growers can use any good quality biostimulants as per requirements and availabilities. Some of the best biostimulants include the following.
- Amino acid biostimulant
- Aagrigro biostimulants
- Plant biostimulants
- Tag bio enriched organic biostimulant
- Stimplex crop biostimulant
- Brand plant biostimulants
- Kelpak biostimulant
- Seaweed biostimulant
- Vitazyme biostimulant
- Ebic biostimulants
- Chitosan biostimulant
- Organic biostimulants
- Activemax biostimulant
- Microbial biostimulants
- Syngenta biostimulants
- UPL biostimulants
- Next biostimulants
- Plantonik biostimulant
- Cytogro biostimulant
- Yara biostimulants
- Radifarm biostimulant
- Adams earth biostimulant
- Valagro biostimulants
A growing number of studies have shown that many microbes are beneficial to soil fertility and productivity in major cropping systems. However, there have been many inconsistent and difficultly repeatable field and controlled trials that have suggested uncertainty about the efficacy and effectiveness of microbial inoculants.
Factors Affecting Efficiency of Microbial Organic Fertilizer
There are various factors including plant species, native microbe communities, environmental conditions, and soil type that directly affects the efficiency and potential of microbial organic fertilizer. They also need to be aligned with complex biotic and abiotic factors such as soil type, cropping systems, irrigation, and biocontrol strategies. To ensure that agricultural microbes can be successfully manipulated, commercialized, and widely used, progress in this area will depend on an understanding of these factors.
The next generation agriculture must make full use of all resources to get maximum crop production at the little expense of environmental footprints and resource utilization. Next-generation agriculture should also design novel aero models that emphasize the perfect combination between biologicals and chemicals. Next generation agriculture, next generation farming, and new generation farming can greatly transform the deprived communities into prosperous ones.
Future Prospects and Challenges for the Use of Microbial Organic Fertilizer
Requirement of Multidisciplinary Approaches
Multidisciplinary approaches are essential in the development of microbial-based solutions that work in conjunction with mineral fertilizer resources. This could create market opportunities and new agricultural paradigms that reflect contemporary conceptions of sustainability.
Development of Sustainable Formulations
Scientists and manufacturers interested in microbial biostimulants must focus on developing stable formulations that can withstand harsh storage conditions and ensuring extended shelf life by limiting viability loss. Similar one:Food Scraps as Valuable Resources
Safe Manufacturing of Microbial Inoculants
Microbial inoculants manufacturing is a critical step. There have been many carriers used, with different results depending on the microbial species or pretreatment methods. These carriers include organic materials such as peat, lignite, and composts and polymeric compounds such as alginate, agar, and pectin.
When designing new microbial formulations, multi- and inter-disciplinary approaches should be considered. This will allow for new insights into an area of research that is still unexplored, such as the combination of new-generation coatings and microbial technology. This could lead to new opportunities in this area.
Development of Control Release Microbial Organic Fertilizer
Microbial biotechnologies, for example, would benefit from emerging technologies like EEF or controlled-release fertilizers. These are not widely used for staple crops and can be too expensive to be used in intensive agriculture.
Recent advances in coating technology have allowed for the creation of new-generation fertilizers that are specifically designed to increase P fertilizer efficiency and uptake. This could help overcome low P availability, which is pH-dependent, easily bounded by divalent cations, and belowground leakage. Thus, a precise release rate and efficient root P uptake can be achieved.
However, little research has been done to produce customized carriers that meet all quality requirements. Combining new-generation coatings and microbial technology is a promising area of research that should be explored more.
A breakthrough in this area could lead to the development of smart fertilizers that match precision agriculture’s few concepts (sensing technology and farming satellite data analysis, controlled release fertilizers, etc.).
