Answers
Answer:
Permitive subsistence farming :
This type is also called as simple subsistence farming. This farming is practised on small patches of land with the help of primitive tools like hoe, dao and digging sticks through family /community labour. This type of farming depends upon monsoon, natural fertility of soil and suitability of other environmental conditions to the crops grown. It is a "slash and burn" method of agriculture (Shifting agriculture).
Intensive subsistence farming :
It is practised in areas with high population density on land. It is labour intensive farming, where high doses of biochemical inputs and irrigation are used for obtaining higher production.
Commercial subsistence farming :
The main characteristic of this type of farming is the use of higher doses of modern inputs, for example high yield variety (HYV) seeds, chemical fertilizers, insecticides, pesticides in order to obtain higher productivity. The degree of commercialization varies from one place to another.
