The prices of slaves in Antebellum America rose and fell along with the price cotton because most slave labour were used in the production of cotton production. Therefore, the rise in the price of cotton causes an increase in the demand of slaves and when cotton price falls, the demand for slaves also decreases.
The wealthy planter of cotton ensured that slave property was exempt from taxation.
Cotton has a long growing season. Slaves plowed the land in March, seeded in early April, and had to chop away the surrounding grasses once the plants began to grow. Then in August, the four-month long picking season began.
