Soil exhaustion can be prevented in a number of ways. Commercial farms often reapply commercial fertilizers every year, but this can be expensive and damaging to the environment. Natural compost from animal waste can be added which is a more natural way to prevent soil exhaustion, but they too can damage the environment from water run off. A better way to prevent soil exhaustion is to rotate crops. Some crops such as corn exhaust soil quickly while others such as beans actually take nitrogen from the atmosphere and replenish the soil. Cover crops can also help prevent soil exhaustion by protecting soil from erosion. Finally, soil exhaustion can be prevented by not stripping land of indigenous plants. Rain forests that are removed often create soil exhaustion because the soil is not longer being fed by the cycle of falling leaves from the rain forest's canopy. Soil amendment, crop rotation, cover crops and keeping original species are the best ways to prevent soil exhaustion.
the way that farmers change the PH of soil is by adding a little bit of lime or eggshells or oyster shells because they are all good ways to make it neutralize.
In what ways can soil be alike
There are several ways that nutrient minerals are lost from the soil. The overuse of the soil in farming, natural weather inclinations and over population are just some of the ways.

Crop Rotation

Well....river valley has rich soil and so they use that soil to farm or it's because the farmers have no life so the river valley gave them water to drink and grow crops that they don't need
Crop rotation was important to the farmers in various ways. This improved the fertility of the soil and also provided them with diverse crops which they could consume and sell among other benefits.
In what ways can soil be alike
not 100% sure, but i would say that they help break down vegetation in the soil and also helps to aerate the ground
The cycle of the nile helped the farmers because, when it would flood, it would unearth alot of fertile, moist soil. This soil, would help farmers grow all sorts of crops. Before the flood came, the farmers would harvest all their crops so they wouldn't be washed away. After the harvest, the cycle would start all over again,
Don't be a near an infected dog, rat or other mammal that is similarly infected. Do not touch soil or water that has been infected.
