True or False: If not enough litter is present, soil temperatures increase, evaporation increases, and biological activity slows.

1. True

2. False

3. N/A

4. Sometimes

The correct answer is: True

The statement is true because adequate litter cover on the soil surface plays a crucial role in regulating soil temperatures, moisture retention, and supporting biological activity. When there is insufficient litter, the soil is more exposed to direct sunlight, which can lead to increased soil temperatures. This is especially problematic in hot weather as elevated temperatures can disrupt the delicate balance of soil microorganisms and inhibit their activity. Additionally, without sufficient litter to shield the soil, evaporation rates can rise significantly. Litter acts as a protective barrier that helps reduce the impact of wind and sun, thereby minimizing water loss from the soil. When evaporation increases, it can lead to drier conditions that are less conducive to supporting the diverse biological activity found in healthy soil ecosystems. In conclusion, the presence of adequate litter is key to maintaining favorable conditions for soil health, helping to sustain temperature, moisture levels, and promoting robust biological processes.
