Question

What is the fundamental characteristic that defines biofertilizers as living organisms?

Options

• They are living microorganisms that improve soil fertility by increasing nutrient availability to plants

• They are synthetic chemical compounds

• They are inorganic minerals extracted from rocks

• They are degraded plant materials and compost

Answer 1

Biofertilizers are fundamentally defined as living microorganisms that improve soil fertility by increasing the availability of nutrients to plants. This living nature distinguishes them from chemical fertilizers, which are synthetic and inorganic compounds, and enables them to perform biological functions that enhance soil quality while maintaining microbial life.
