Contour plowing is like using a comb to style your hair, but instead of hair, we're combing the dirt! Let's imagine that the earth is like the hair on your head, and when hair is long and all tangled up, it can be hard to brush through. When earth is like this, it can also be hard to grow crops because the soil is all over the place and not level.
Now imagine combing all the dirt into tiny little rows that are all straight and lined up like soldiers. By doing this, we are helping the soil stay in place and not get washed away when it rains. This, in turn, helps farmers grow better crops because the dirt is now more organized and has nutrients for the crops to thrive. Water, like rain, will flow along the rows of dirt and won't disrupt the plants from growing, which is very important.
So, contour plowing is when farmers comb the dirt into neat rows that follow the curves of the land, making sure the hills and valleys on their land are all covered in the most efficient way possible. This helps keep the soil in place and makes it easier for farmers to grow good crops!
