Agriculture in Chile encompasses a wide range of different activities due to its particular geography, climate, geology and human factors. Historically agriculture is one of the bases of Chile's economy, now agriculture and allied sectors—like forestry, logging and fishing—account only for 4.9% of the GDP as of 2007 and employed 13.6% of the country's labor force. Some major agricultural products of Chile include grapes, apples, onions, wheat, corn, oats, peaches, garlic, asparagus, beans, beef, poultry, wool, fish and timber.[1] Due to its geographical isolation and strict customs policies, Chile is free from diseases such as Mad Cow, fruit fly and Phylloxera, this plus being located in the southern hemisphere (having quite different harvesting times compared to the Northern Hemisphere) and its wide range of agriculture conditions are considered Chile's main comparative advantages. However, the mountainous landscape of Chile limits the extent and intensity of agriculture so that arable land corresponds only to 2.62% of the total territory.[1]
Chile's principal growing region and agricultural heartland is the Central Valley, bounded by the Chilean Coast Range to the west, the Andes to the east, Aconcagua River to the north, and Bío-Bío River to the south. In the northern half of Chile, cultivation is highly dependent on irrigation. South of the Central Valley, cultivation is gradually replaced by aquaculture, silviculture, sheep and cattle farming.
