In this system,farmes clear a new plot of about a hectare each year.Small trees are felled and large trees are killed by girdling (cutting away a ring of bark),so that sunlight can penetrate through to the ground.After a few weeks of drying, the branches,leaf litter,and fallen trunks are burned to prepare a rich seedbed of ashes.Fast-growing crops,such as bananas and papayas,are planted immediately to control erosion and to shade root crops,such as cassava and sweet potato,which anchor the soil.Maize,rice,and up to eighty other crops are planted in a riotous profusion.Although they would not realize the terms,these indigenous people are practing mixed perennial polyculture.
