​​Constrains in Biofertilizer Development and Environmental Factors Influencing its Survival in Soil: A Review

Bio-inoculants (Biofertilizer) are an agricultural input that helps to keep the environment clean. By definition biofertilizers efficient strains of isolated microorganisms help plants grow in a variety ways, both directly and indirectly. Biological nitrogen fixation, phosphate solubilization, mobilisation, siderophore generation phytohormone production some direct methods. The majority bio-inoculants perform better laboratory conditions but fail achieve same results field. Due poor performance field conditions, not widely accepted by farming community. Soil pH, temperature chemical residues considered as important abiotic stress. key soil biotic elements native microflora, predatory organisms virus. Some bacteria able live despite stress, total efficacy applied biofertilizer is diminished. must resist stresses soil, depending on circumstances. We look at obstacles confront terms survival
