n 2-fixing bacteria were isolated from three different materials: (1) soil that adhered to the roots (rhizosphere), from which soil aggregates removed from the collected roots were chosen at random; (2) roots without washing (with removal of adhered soil), from which fine root fragments of approximately 1 cm length were sectioned; and (3) washed roots macerated in water, from which 0.1
soil organisms feed on organic compounds in the soil, breaking down and releasing nutrients the plants need but cannot extract from the soil themselves. a healthy soil food web of organisms breaking down organic matter into a form available for nutrient uptake by plants’ roots improves the fertility of the soil and the vigor of the plants.
