The practice of crop rotation uses nitrogen fixation to create fertile fields. First, a plant without a nitrogen-fixing relationship, such as corn, is planted. After the harvest, a nitrogen-fixing plant replaces the initial crop. Instead of harvesting the nitrogen-fixing plant, however, it is plowed under. The cycle continues in this manner. Why would nitrogen-fixing plants be plowed under instead of harvested? * To increase water retention. Nitrogen-fixing plants are not a food crop. To increases usable nitrogen in the soil. To decrease bacteria in the soil.

Plant growth is most likely to be limited by the available supply of usable: a. nitrogenb. carbonc. oxygend. phosphorus

Plant growth is limited by available nitrogen. Why is nitrogen fixation a limiting factor? There is very little nitrogen available after fossil fuel combustion utilizes the available nitrogen. Nitrogen must be produced by bacteria due to the inability of recycling by decomposers. There is no nitrogen in the atmosphere; it is only found in aquatic biomes. The stability of nitrogen gas makes it difficult to turn into nitrogen for living things.
