Negative soil pollutant is

reduction in soil productivity due to erosion and over use

A negative soil pollutant refers to factors that diminish soil productivity through processes such as erosion and overuse. These pollutants adversely affect soil health, leading to reduced agricultural yields and environmental degradation.

Key Processes Leading to Negative Soil Pollution:

• Erosion: The displacement of the upper layer of soil, primarily due to water and wind, resulting in the loss of nutrient-rich topsoil essential for plant growth.
• Overuse: Continuous and intensive farming without adequate soil management practices depletes soil nutrients, leading to decreased fertility over time.

Impacts of Negative Soil Pollution:

• Reduced Crop Yields: Degraded soils produce lower agricultural outputs, affecting food security and farmers' livelihoods.
• Loss of Soil Structure: Erosion and nutrient depletion compromise soil integrity, making it more susceptible to further degradation.
• Biodiversity Decline: Healthy soils support diverse ecosystems; pollution leads to habitat loss for many organisms.

Understanding and addressing negative soil pollution is crucial for sustainable agriculture and environmental conservation. Implementing effective soil management practices can mitigate these adverse effects, ensuring long-term soil health and productivity.
