Question

How does burning of certain areas help in creating fertile land?

• A. Makes the land produce alluvial soil on its own.
• B. Main competitors of crops like weeds and threats like pests are destroyed.
• C. Crops react well to the heat produced by fire.
• D. Provides nutrients that deposit on the soil in the form of ashes.

Answer 1

Answer: (B), (D)

Provides nutrients that deposit on the soil in the form of ashes.

Burning provides suitable conditions to crops as their main competitors like weeds and threats like pests are destroyed. Burning also provides nutrients that deposit on the soil in the form of ashes. Burning typically results in the reduction of fuel and organic soil nutrient pool sizes, increases soil nutrient turnover rates, and redistributes nutrients through the soil profile.
