Which characteristic of liquid manure contributes to its increased risk of loss compared to solid manure?

Liquid manure has a higher susceptibility to movement, making it riskier in terms of loss compared to solid manure. This characteristic stems from its fluid nature, which allows it to easily flow across the landscape, particularly during rainfall or when the ground is saturated. Unlike solid manure, which tends to stay in place, liquid manure can quickly infiltrate into soil and runoff into water bodies if not managed carefully. This heightened mobility increases the risk of nutrient leaching into groundwater or runoff into surface water, which can lead to environmental issues such as water pollution.

The other characteristics mentioned do contribute to various aspects of manure management, but they do not specifically address the primary concern regarding the increased risk of loss due to the physical properties of the manure itself. For example, higher nutrient concentration can lead to pollution but does not directly explain the movement aspect. Additionally, enhanced ozone depletion potential and increased labor demands relate to other environmental impacts and management challenges, rather than the critical issue of nutrient loss during transport and application.
