The specialised commercial cultivation of cash crops on estates or plantations is a very distinctive type of tropical agriculture and is found in many parts of Asia, Africa and tropical America. Some of the main plantation crops are rubber, oil palm, cotton, coffee, tea and cocoa, fruits like pineapples and bananas, as well as sugarcane and soybeans.
Plantation agriculture is the product of colonialism. Plantations have been developed in response to a demand in Europe for foods, spices, fibers, and beverages, which because of climatic constraints, could be produced only in the tropics or sub-tropics. Over the centuries the demand for most of these items has increased with the growth of world population.
Plantation agriculture is an export-oriented specialised farming method where emphasis is given to raise a single crop. It involves not only cultivation of crop but also processing, packaging, transporting and exporting of the product.
To initiate and to maintain a tropical plantation, large sums of money are required. As many plantations are located in previously undeveloped or sparsely populated areas, far from urban centers, a minimum network of communication by road or rail has to be developed first . A large amount of capital is put into building roads, buying machinery and building factories to process the crops harvested from the plantations .
Plantation owners also invest large amounts oftheir capitalon fertilisers and pesticides. Fertilisers are applied to plantation crops as frequently as these crops use up nutrients from the land quickly. Since plantations usually grow onetype ofcrop, pest attacks can cause total destruction of the plantations. Pesticides are therefore used in huge quantities to prevent crops from being entirely destroyed by pests .
Due to thelarge size of a plantation, a lot of labour is needed to tend to the crops and work in the nearby processing factories.
