what are biofertilizers

Biofertilizers are substances that contain living microorganisms, such as bacteria, fungi, and algae, that promote plant growth by improving nutrient acquisition. They can be applied to seeds, plant surfaces, or soil, and colonize the rhizosphere or the interior of the plant. Biofertilizers can be expected to reduce the use of synthetic fertilizers and pesticides, but they are not yet able to replace their use. Biofertilizers have been shown to have varying effects in different environments, and even within the same environment. However, they have been proven to enhance the sustainability and health of the soil, and healthy plants can be grown through their use. Biofertilizers are required to restore the fertility of the soil, especially after prolonged use of chemical fertilizers that degrade the soil and affect crop yield. Biofertilizers are eco-friendly fertilizers that do not harm the environment and are also cost-effective. Some examples of biofertilizers include mycorrhizal fungi, blue-green algae, and bacteria such as Azospirillum, Azotobacter, and Acetobacter. Biofertilizers can be in the form of liquid biological and plant nutrient solutions, such as PrimAgro N Nitrogen Biofertilizer and Phosphorus Biofertilizer.
