The Importance of Arable Land in Agriculture

Land suitable for agriculture is called

a. arable land.
b. physiological land.
c. arid land.
d. population density.
e. agricultural density.

Final answer:

Arable land is land that can be used to grow crops and is essential for agriculture. The United States has a significant portion of its land as arable, and it is vital in assessing a region's capacity to support its population through agricultural production. The quality of soil and management of arable land determines the success of agriculture in sustaining the increasing human population.

Explanation:

Land suitable for agriculture is called arable land. This term specifically refers to land that can be used to grow crops. In the context of agricultural landscapes, the United States has a vast amount of arable land, with millions of acres dedicated to both crop production and livestock grazing.

Arable land is a precious resource, as soil quality significantly impacts the potential for agricultural productivity. Additionally, in areas like South Asia, physiologic density offers insight into the number of people per square mile of arable land, indicating the pressure on agricultural resources. With the human population expected to grow, the carrying capacity of arable land becomes critical in supporting this increase.

In several countries, despite challenges such as poor soils and harsh climates, innovative farming techniques have been developed to optimize the use of available arable land. Yet, with the constant increase in population, if the available arable land is not managed properly, it could lead to food shortages and affect the overall sustainability of the population.
