Characteristic feature of primitive subsistence farming:

Dependence on monsoon and natural fertility of the soil:
One of the characteristic features of primitive subsistence farming is its heavy dependence on monsoon rains for irrigation. This type of farming relies on the natural fertility of the soil for crop production. Farmers in this type of farming do not use artificial irrigation methods or modern techniques to enhance the productivity of their land. They solely depend on the rainfall and the inherent fertility of the soil to grow their crops.

Reliance on irrigation for higher production:
Unlike modern farming methods that rely on irrigation systems to provide water to crops, primitive subsistence farming does not use artificial irrigation. Instead, it relies solely on the rainfall patterns of the region. This means that the productivity of the land is highly dependent on the monsoon season, and if there is a lack of rainfall, it can lead to poor crop yields and even famine.

Use of modern tools and machinery:
Primitive subsistence farming does not make use of modern tools and machinery. Instead, it relies on traditional and simple tools such as a hoe, sickle, and wooden plow for cultivation. The lack of modern machinery makes the process of farming labor-intensive and time-consuming. Farmers have to rely on their physical strength and manual labor to carry out the various tasks involved in farming.

Use of high doses of biochemical inputs:
Primitive subsistence farming does not involve the use of high doses of biochemical inputs such as fertilizers and pesticides. Farmers in this type of farming rely on organic methods and natural sources of nutrients for their crops. They may use traditional methods such as crop rotation and animal manure to maintain the fertility of the soil. This type of farming focuses on sustainability and the preservation of the natural environment.

In conclusion, the characteristic features of primitive subsistence farming include its reliance on monsoon rains and natural soil fertility, lack of modern tools and machinery, and a focus on organic methods rather than high doses of biochemical inputs. This type of farming is heavily influenced by environmental factors and requires labor-intensive manual work from farmers.
