Soil and Plant Health Quiz

Heavy rainfall can leach chemicals and nutrients from the soil into lakes, contributing to eutrophication and negatively impacting water quality.

Overuse of fertilizers can lead to dehydration and scorching of plants, imbalance in nutrient availability, and potential toxicity from excess trace elements.

Salinization is the accumulation of salts in the soil, which occurs when water evaporates, leaving salts behind, and it can kill plant roots and prevent soil cultivation.

<p>To mitigate issues, strict limits on fertilizer application should be enforced, and replacing synthetic fertilizers with organic alternatives can be beneficial.</p> Signup and view all the answers
