Final answer:
The more fertile soils and milder climate in the Rhode Island colony resulted in more productive and profitable agriculture compared to other New England regions, where farming was typically for self-sufficiency.
Step-by-step explanation:
The better soils and slightly warmer climate of Rhode Island compared to other New England colonies made agriculture more productive and profitable. Due to the challenging agricultural conditions in much of the New England regions, such as long winters and rocky soil, farming there was largely for self-sufficiency rather than market-oriented.
However, Rhode Island's more conducive agricultural environment allowed for a broader and more intensive range of farming activities, leading to greater prosperity among its farmers.
