Explanation: 

Detailed explanation-1: -Moreover, nutrients released from the burned material, which includes dead plants and animals, return more quickly into the soil than if they had slowly decayed over time. In this way, fire increases soil fertility-a benefit that has been exploited by farmers for centuries.

Detailed explanation-2: -If fires are hot enough, they can kill microorganisms and partially sterilize the soil. Severe fires can increase soil density, reduce porosity and permanently alter soil texture. Due to decreased water infiltration rates and water storage capacity, damaged soils thereby accelerate run off and erosion.

Detailed explanation-3: -Fire is a powerful ecological and evolutionary force that regulates organismal traits, population sizes, species interactions, community composition, carbon and nutrient cycling and ecosystem function.

Detailed explanation-4: -By spraying fire extinguishing solutions. ii. Strong blowers can be used to change the direction of the wind.
