What is a negative consequence of over-applying lime to soil?

Over-applying lime to soil can lead to unnecessary expenses, making this the correct choice. Lime is typically used to correct soil acidity and improve pH levels, but applying too much can result in a financial burden without providing additional benefits for crop growth or soil health. Farmers may spend more money on excess lime that does not contribute positively to the soil or crop yields, especially if the soil pH is already within an optimal range for nutrient availability.

While increased crop yield and enhanced nutrient availability may seem like positive outcomes of lime application, over-application does not guarantee these benefits and may disrupt the balance of nutrients. Additionally, lime is used specifically to increase soil pH, so decreased soil pH levels as a result of over-application would not occur. Understanding the appropriate amount of lime to apply is crucial for effective nutrient management and cost efficiency in agricultural practices.
