|7. Planting trees outside woodlots and forests|
When intercropping trees and crops, follow in sequence and combine restoration of the soil by trees with agriculture. The land is usually devoted to food growing for some years before trees are planted. Thereafter the agricultural crop is grown together with tree seedlings for some years until the shade from the trees interferes with the growth of the crop or the agricultural crop with the growth of the trees.
