The rate at which soil bacteria perform nitrogen fixation provides information to xaviers about lower productivity of its field.

The rate at which soil bacteria perform nitrogen fixation best explain the processes to xaviers observation because nitrogen fixation provides nutrients to the plants. If the rate of nitrogen fixation is higher then more nutrients are available to the plants and the plant has more growth.

While on the other hand, when the rate of nitrogen fixation is lower then less nutrients are available to plants which leads to less growth and development of plant so we can conclude that the rate at which soil bacteria perform nitrogen fixation provides information to xaviers about its field lower productivity.

Answer from: SophieStar15

the rate at which soil bacteria perform nitrogen fixation

Explanation:

Plants cannot use nitrogen in the air directly as nitrogen present in the air cannot react with other compounds. Nitrogen present in the air is converted into ammonia so that the plants can utilize it. The nitrogen-fixing bacteria convert the atmospheric nitrogen into ammonia.

When the same crop is grown again and again on a soil, the resources become depleted in the soil. Also, the number of nitrogen-fixing bacteria decreases.

Hence, it is essential to practice crop rotation.
