Vegetable crops require high nutrients for rapid growth, flowering, and fruiting. Continuous use of chemical fertilizers can reduce soil fertility and increase production costs. Biofertilizers provide a sustainable and cost-effective solution by improving soil health and nutrient availability naturally.

🌱 What Are Biofertilizers?

Biofertilizers are beneficial microorganisms that enhance plant growth by increasing nutrient availability in the soil. These microbes colonize the root zone and support healthy crop development.

Key biofertilizers include:

• Azotobacter
• Azospirillum
• Bacillus subtilis
• Trichoderma
