What is the difference between primitive subsistence farming and mixed farming

Primitive Subsistence Farming

(i) Farming practices in which crops are cultivated for local consumption.

(ii) Farms are small and food crops are cultivated such as rice and wheat.

(iii) Old tools and implements are used by the farmers.

Mixed farming  is a type of agricultural practise in which different activities are conducted on the same farm. The purpose is to increase the income through different sources. Eg. Farming of crops and rearing cattle on the same land is known as mixed farming. It helps in recycling soil nutrients by crop rotation. It also helps in maintaining soil biodiversity and prevents soil erosion.  .
