Extensive use of agrochemicals in agricultural practices has been found to cause environmental disturbances and public health hazards affecting food security and sustainability in agriculture. [22] Biofertilizers offers an alternative solution for such agrochemicals, and show yield increase of up to about 10–40% by increasing protein contents ...
Conventional farming methods use chemical fertilizers, pesticides, and herbicides to safeguard crops from pests and diseases. However, these chemical agents have adverse environmental impacts, contributing to environmental pollution. The use of agricultural chemicals has been linked to the decline of plant and animal species, as well as harm to ...
In addition to being a model organism for studying diazotrophs, it is used by humans for the production of biofertilizers, food additives, and some biopolymers. The first representative of the genus, Azotobacter chroococcum, was discovered and described in 1901 by Dutch microbiologist and botanist Martinus Beijerinck.
Consequently, the widespread use of phosphate fertilizers has increased soil fluoride concentrations. [94] It has been found that food contamination from fertilizer is of little concern as plants accumulate little fluoride from the soil; of greater concern is the possibility of fluoride toxicity to livestock that ingest contaminated soils.
When PSB is used with rock phosphate, it can save about 50% of the crop requirement of phosphatic fertilizer. [ citation needed ] The use of PSB as inoculants increases P uptake by plants. Simple inoculation of seeds with PSB gives crop yield responses equivalent to 30 kg P 2 O 5 /ha or 50 percent of the need for phosphatic fertilizers.
Biostimulants also termed as plant conditioners or bioeffectors are substances, cultures of micro-organism, and mixtures of materials used to promote the growth of crop plants and can include natural or artificial plant growth regulators and biofertilizers. They do not include pesticides or fertilizers.

Diazotroph fertilizer is a kind of biofertilizer that can use nitrogen-fixing microorganisms to convert molecular nitrogen (N 2) into ammonia (which is the formation of nitrogen available for the crops to use). These nitrogen nutrients then can be used in the process of protein synthesis for the plants.
