Introduction:
Soil fertility refers to the ability of the soil to provide essential nutrients and support plant growth. In the savanna climate, which is characterized by a long dry season and a short rainy season, various factors can contribute to the deterioration of soil fertility. However, excessive snowfall is not one of these factors.

Explanation:
1. Torrential downpours of heavy rain:
Torrential downpours of heavy rain can lead to soil erosion and nutrient leaching. The force of the rain can cause the top layer of soil to be washed away, taking away valuable nutrients with it. This can result in reduced soil fertility.

2. Intense heating and evaporation:
In the savanna climate, intense heating and evaporation are common during the dry season. The high temperatures can cause moisture to evaporate from the soil, leaving it dry and nutrient-depleted. This can negatively impact soil fertility and hinder plant growth.

3. Overgrazing by animals:
Overgrazing by animals, such as cattle or goats, can have detrimental effects on soil fertility. When animals graze excessively in an area, they remove vegetation and disturb the soil. This can lead to soil compaction, erosion, and a decrease in organic matter content, all of which contribute to soil fertility decline.

4. Excessive snowfall:
Excessive snowfall is not a factor responsible for the deterioration of soil fertility in the savanna climate. The savanna climate is characterized by a long dry season and a short rainy season, with little to no snowfall. Therefore, snowfall is not a significant factor affecting soil fertility in this climate.

Conclusion:
In conclusion, excessive snowfall is not a factor responsible for the deterioration of soil fertility in the savanna climate. Other factors such as torrential downpours of heavy rain, intense heating and evaporation, and overgrazing by animals can have a significant impact on soil fertility in this climate. Understanding and addressing these factors are crucial for the sustainable management of soil resources in the savanna regions.
