Agriculture

Question 1 :

Agriculture is a Latin word that means "to cultivate the soil." Crops, fruits, vegetables, flowers, and animal rearing are all examples of primary activities. Farming is another name for it.

 


Question 2 :

Answer :

Agriculture is influenced by several elements, including favorable soil topography and climate.


Question 3 :

What is shifting cultivation? What are its disadvantages?

 

Answer :

Shifting cultivation, sometimes known as slash-and-burn farming, is a kind of farming that entails removing trees, burning the felled trees, mixing the ashes with soil, and then planting maize, yam, potatoes, and cassava on the cleared land. The land is abandoned as the soil loses its fertility, and the farmer goes on to a new plot.

The following are some of the disadvantages of this form of farming:

  1. Deforestation of land. 

  2. The soil loses its fertility with time.

  3. Erosion of the soil.

  4. Small farming plots that are insufficient to feed a large population.

 


Question 4 :

What is plantation agriculture?

Answer :

Plantation agriculture is a kind of commercial farming that focuses on a single crop, such as tea, coffee, sugarcane, cashew, rubber, bananas, or cotton. This form of farming necessitates a significant amount of labour and capital. The fruits and vegetables are prepared on the farm or in adjacent companies. Major plantations, such as rubber in Malaysia, coffee in Brazil and tea in India, are found in tropical regions of the world.
