The soils on river floodplains vary depending on the sediment load of the river, the frequency and size of floods, and the height of the water table which is related to the height of the floodplain above river level (Fig. 8). Where rivers are fast flowing, they often carry a high sediment load of larger materials (boulders, gravel, and sand) which are deposited to form rapidly draining, low-nutrient 44 3 Soils Born of Water Fig. 5 River floodplains are subject to periodic inundation.

Where rivers drain glaciers, or highly erodible rapidly uplifting mountain chains, they carry huge sediment loads that fill and block the river channel causing the river to overflow and diverge into new paths. The river thus migrates back and forth across the floodplain, building braided river channels and depositing new layers of gravel, sand, and silt (Fig. 7). The soils on river floodplains vary depending on the sediment load of the river, the frequency and size of floods, and the height of the water table which is related to the height of the floodplain above river level (Fig.

Young soils often contain very little nitrogen, a nutrient essential for plants. Thus many of the first plants to colonize the ash and pumice after the eruption were nitrogen-fixing plants, which means they have symbiotic bacteria in their roots that gather nitrogen from the atmosphere and share it with the plant. Even in areas where there are remnants of the old soils, numerous nitrogen-fixing plants will enter. As time passes, nitrogen accumulates in the soil along with organic matter and other nutrients.
