Q:What are it's advantages and disadvantages in both commercial farming and subsistence farming?
Good question Advantages of Commercial Farming Can generate cash, the products are therefore intended to be marketed for profit. An extra profit is needed to fund the next cropping activities. A positive impact on an economy, unemployment decreases more people and resources are fully utilize and as a result government generates more revenue through taxes which makes an economy of a country more powerful. Disadvantages of Commercial Farming is that only certain crops would be produce as it has more money value. Peoples' would not get a variety to choose. Advantages of Subsistence Farming The people who worked there can get the food and it is a quite cheap as compare to Commercial Farming where excess of money is required to operate the farm whereas in subsistence farming you just have to buy a little piece of land and little money to be spend on the crops. Disadvantages are there is no proper source of income in this farming system. Difficult to buy seeds for new crops due to a cash-flow problem. A farmer has to work hard to yields the crops.
