Answer:
Land west of the Mississippi River was not good for farming.
Step-by-step explanation:
In colonial America agriculture was extremely important for the small population that settled in this territory. Agriculture was the most significant and important form of food and small trade that was beginning to rise, so it was important for communities to settle in a region with soil and climate conducive to agriculture.
The land west of the Mississippi River was not good for agriculture, and this made the land unattractive to people, but as the good land for agriculture was quickly populated, some people had to occupy the west of the Mississippi River, but few people submitted to a land with little agricultural capacity.
