Agricultural soils are the top layer of the Earth's surface that are specifically used for growing crops. These soils are rich in nutrients and organic matter, which help support plant growth. They are formed through the weathering of rocks and the decomposition of organic materials, making them essential for food production. Different types of agricultural soils, such as clay, sandy, and loamy soils, have unique properties that affect water retention and nutrient availability. Farmers often test and manage these soils to optimize crop yields and ensure sustainable farming practices, which are vital for feeding the growing global population.
