First, farmers have to find a designated spot where they want to plant, somewhere that is close to their villages or settlements. Before they can plant, they have to remove the plants and vegetation that normally covers the land. Using axes and machetes, farmers cut down most of the tall trees, which normally help bring down the smaller trees.  Next, the farmers burn the debris under carefully controlled conditions. Whenever it rains, the rain comes and washes the fresh ashes into the soil, providing the needed nutrients. The cleared area is known as a swidden.  The cleared land can support crops only up to three years or less. After those three years, the soil nutrients are rapidly depleted and the land becomes too infertile to nourish crops. When the swidden is no longer fertile, the villagers and farmers find a new site to begin clearing out. They leave the old site uncropped for many years, allowing it to go back to its normal vegetation state, this could take up to twenty years. 
features-
1  Clearings made in the rainforest by cutting and firing trees (Slash and Burn)
2 Largest trees often left because they are difficult to move and can provide a source of food in the form of fruit.
3.  Ash is scattered after trees have been burned to fertilize the ground.
4. Little fertilizer is added apart from the ash, so the nutrient levels drop quickly leading to the cultivators abandoning the plot and finding a new one after 7-10 years.

5.Labour intensive little use of machines (some have chain saws).  Crops tend to be planted using digging sticks.
6.  Crops planting between remaining tree trunks which decompose slowly adding extra nutrients to the soil.
7.When the clearing is abandoned it is left for many years, allowing the vegetation to recolonise.
8.With a low population density, this form of agriculture is sustainable.
