The use of nitrogen-fixing bacteria in agriculture is an effective way to improve soil fertility and overall crop productivity. Bacteria such as Rhizobium, Azotobacter, and Azospirillum are able to extract nitrogen from the soil and convert it into a form that can be absorbed by plants, which is essential for the formation of protein, DNA, and RNA in plants. By utilizing the capabilities of these bacteria, the use of synthetic chemical fertilizers can be varied, thereby reducing the detrimental dampening effects on water quality and the environment. In addition, nitrogen-fixing bacteria improve water use efficiency and contribute to the health of aquatic ecosystems. The use of these bacteria has the potential to improve the results of a more thorough analysis with less cost and less environmental impact.

The research method used is the literature review method to explore more deeply the role of mycorrhizal fungi in increasing the efficiency of plant nutrient uptake. The results stated that mycorrhizal fungi have great potential as microorganism partners in increasing plant nutrient uptake. With its ability to expand the root absorption area, and enhance plant growth, improve soil structure and reduce pollution, mycorrhiza can contribute significantly to agricultural sustainability.

Microorganisms are highly beneficial in sustainable agriculture as they are key components of the soil ecosystem and participate in various processes that enhance soil fertility, improve crop quality, and reduce reliance on synthetic chemicals. This study employs a meta-analysis or literature review method to examine previous research on the role of microorganisms in agriculture, specifically on how microorganisms play a critical role in sustainable farming. Most available studies rely on qualitative data or case studies, limiting the ability to conduct more in-depth quantitative analysis. The results indicate that waste processing into organic compost fertilizer is crucial. Applying organic farming methods improves crop quality while maintaining ecosystem balance.

The use of fertilizer in plant cultivation is basically carried out to meet the availability of nutrients for plants in order to obtain optimal results. However, excessive use of fertilizer can actually have a negative impact on the ecosystem, such as environmental pollution and decreasing soil quality. The use of biofertilizer as a substitute for biological fertilizer is an alternative that can be used to reduce dependence on chemical fertilizers. Biofertilizer is a biological fertilizer containing various live microorganisms which is used to increase plant productivity by improving the quality of soil fertility. One of the microbes that acts as a biofertilizer is the Bacillus sp. The purpose of this article is to find out how Bacillus sp. functions as a biological fertilizer that can increase soil fertility and increase crop productivity. Bacillus is a genus of bacteria that can be used as a biofertilizer because of its more varied antagonistic mechanisms and ability to produce endospores. The method used in this article is a meta-analysis or literature review method in several journals published online which are integrated with Google Scholar.

Organic farming has increasingly become a preferred choice in sustainable agricultural systems due to its significant benefits for environmental balance and quality. One of the key elements in organic farming is soil microorganisms, which play a crucial role in enhancing soil fertility and supporting plant health. Soil microorganisms, such as nitrogen-fixing bacteria, phosphate-solubilizing microbes, mycorrhiza, and organic matter decomposers, contribute significantly to fertilization efficiency and nutrient availability, as well as improving plant resistance to pathogens. The utilization of soil microorganisms as biofertilizers can reduce dependency on chemical fertilizers, mitigate environmental pollution, and increase agricultural productivity sustainably. Furthermore, soil microorganisms can improve soil structure, extend root longevity, and stimulate plant growth. The selection of appropriate microorganisms according to soil conditions and intended use is essential to maximize their benefits. Therefore, the application of soil fertility-promoting microorganisms as part of sustainable agricultural technology holds great potential to enhance environmentally friendly and efficient agricultural outcomes.

Crop productivity is one of the key components in supporting the sustainability of the agricultural sector and global food security. However, challenges such as soil degradation, dependence on chemical fertilizers, and climate change necessitate more innovative and environmentally friendly approaches. Soil microorganisms play a significant role in improving crop productivity through biological mechanisms such as nitrogen fixation, organic matter decomposition, mycorrhizal symbiosis, and the production of bioactive compounds that protect plants from pathogens and abiotic stress. Microbiology-based biotechnology approaches, such as the use of biofertilizers and biopesticides, offer environmentally friendly solutions to address modern agricultural problems. This research aims to review the role of microorganisms in improving crop productivity, focusing on the application of microbiology-based biotechnology. The research method used is a literature study or meta-analysis of relevant literature and research in the last 10 years. The results of the discussion show that microorganisms such as Rhizobium, Azospirillum, Trichoderma, and mycorrhiza have a major contribution in improving soil fertility, crop yields, and plant resistance to environmental stress.

Soil fertility is an important element in agricultural sustainability, especially in supporting plant growth. One natural way to increase soil fertility is through Biological Nitrogen Fixation (FNB) by Rhizobium bacteria. These bacteria have a symbiotic relationship with legume plants, forming root nodules that convert atmospheric nitrogen into compounds that plants can absorb, such as ammonium (NH4+). The purpose of this article study is to determine the potential of Rhizobium bacteria in increasing and efficiency of nitrogen fixation which has an impact on soil fertility and increasing plant productivity. This study adopts a library research method or approach, which involves a series of systematic activities, starting from collecting data through various library sources, reading in depth, recording important information, to processing the research materials. The study results show that Rhizobium can reduce dependence on chemical fertilizers, increase soil fertility, and produce growth hormones that support nutrient absorption. These findings emphasize the important role of Rhizobium in supporting sustainable agriculture, especially in tropical regions where access to synthetic fertilizers is minimal.

This study aims to explore the root growth patterns of cucumber (Cucumis sativus L.) cultivated in a polybag system, and examine the implications for nutrient absorption efficiency and plant survival. The method used was a systematic literature review, with narrative analysis of recent studies in the last five years. Data were analyzed to identify the relationship between root architecture, growing medium, and nutrient absorption efficiency.  The results showed that the polybag system, with its limited root growing space, promoted adaptation of root growth patterns, including an increase in lateral root density and a reduction in primary root length. Coconut fiber- and vermiculite-based growing media were shown to increase nutrient absorption capacity by up to 30%, while inoculation of rhizosphere microorganisms, such as mycorrhiza, increased phosphorus use efficiency by up to 25%. In addition, optimal root zone temperature plays an important role in supporting root metabolic activities.  The conclusion of this study confirms that optimizing root growth patterns through growing media, temperature management, and utilization of microorganisms can significantly increase the productivity of cucumber plants. These findings provide a basis for developing more efficient and sustainable cultivation strategies in modern horticultural systems.
