You may have not known that soil problems can lead to water problems too.
Floods and droughts are two extreme water problems and result from the misuse of soil and its plant cover.
Humans deplete groundwater largely through runoff during rainy periods and through over consumption in cities.
Deep wells, used to supply drinking water and people's other necessities, draw heavily on the supply of groundwater thus lowering the water table.
Too much runoff water results from heavy rains.
Floods are an aftermath of the denuding of the forests and the conversions of original tall-grass prairies to rice fields and marshes.
With less spongy topsoil to absorb water, rains fall on hard subsoil clay, rush through deep gullies, and flood the lower areas.
Because much of our water supply rushes to the sea, drought later occurs.
So if you want to keep away from this kind of situation you might try to opt for soil conservation.
There are lot of ways in order to prevent the loss of soil.
First is to cover crops and row crops.
Cover crops like cassava, rice, wheat, oats and rye are plants which grow close together and bind the soil with a dense mat of roots.
Row crops, such as corn, beans, tobacco, and tomatoes, are planted in rows in cultivated fields.
Next is to use some commercial fertilizers.
These are used to restore soil minerals.
You can also opt for a very creative type which is through crop rotation.
This is an alternation in the planting of crops between those that use nitrates and those that replace nitrates.
For example, the first crop might be corn, followed by rice, then by grass or clover.
Legumes like clover, cowpeas, string beans, peanuts, and others are important in a rotation cycle because they support nitrogen-fixing bacteria on their roots.
Crop rotation restores minerals in soil.
