What is Cash Crop Farming? Cash crop farming is for profit. Also called commercial farming and cash cropping, it is a farming venture in which cash crops are grown. Cash crops are those which are produced for the purpose of generating cash or money. The products are therefore intended to be marketed for profit. Individual farmers just naturally grow cash crops as a livelihood and to generate cash for the family's needs. An extra profit is needed to fund the next cropping activities. The farming methods employed differ from farmer to farmer and from country to country.
