Microbial Nano-Biofertilizers: A solution for making agriculture sustainable

In agriculture, crop yield and plant health hinge critically on the availability of essential nutrients and the quality of soil. Plants depend heavily on both micronutrients and macronutrients, which are integral to their growth and overall yield. However, numerous fields experience soil health degradation due to abiotic stressors, resulting in variations in pH, texture, microbiome, and nutrient availability. This can lead to insufficient nutrient supply, manifesting as stunted growth and poor plant health. The introduction of eco-friendly green mineral nanoparticles in nano-formulations offers a promising pathway to address these challenges and propel sustainable agricultural practices.

This Research Topic aims to investigate research on how to transform infertile and subfertile soils into nutrient-rich, healthy environments using nano-biofertilizers. Nano-biofertilisers are innovative fertilizers that combine nanotechnology and biological processes to enhance agricultural productivity. They consist of nanoparticles that improve nutrient delivery and plant uptake or boost beneficial soil microorganisms' activity. Due to their small size, nano-biofertilisers offer a high surface area-to-volume ratio, enabling efficient and controlled nutrient release. This technology can increase crop yields, enhance soil health, and support sustainable agricultural practices by reducing nutrient leaching and environmental pollution.

By leveraging innovative, economical, and climate-resilient nano-solutions, this research provides farmers with superior alternatives to traditional chemical and bio-fertilizers. The focus is on crafting tailored nano-biofertilizer applications that cater specifically to the nutrient deficiencies of individual soil types, promoting robust plant growth.

To achieve comprehensive insights into this transformative approach, the Scope of this Research Topic encompasses:

o The synthesis of nutrient nanoparticles using prokaryotic and eukaryotic microbes.

o Development and application of nanoformulations that enhance soil fertility and plant health.

o Investigation of the environmental and economic benefits of nano-biofertilizers over conventional options.

We welcome submissions on but not limited to the following themes:

o Micronutrient nano-biofertilizers based on bacteria, cyanobacteria, and fungi.

o Macronutrient nano-biofertilizers based on bacteria, cyanobacteria, and fungi.
