Excessive application of fertilizer
The reason for the pond in the center of the park to now be covered with algae is the excessive application of fertilizer.
- A plant can really die from too much fertilizer, and excess fertilizer can cause toxic algal blooms in lakes and streams that are dangerous to people and their pets as well as other aquatic life.
- Aquatic "dead zones" are also a result of excessive fertilizer runoff from agricultural and lawn applications in coastal areas.
<h3>What consequences might excessive fertilizer use have?</h3>
- By increasing the soil's salt concentration, excessive fertilizer changes the soil and might harm beneficial soil microbes.
- Over-fertilization can result in abrupt plant growth with insufficient roots to provide the plant with enough water and nutrients.
<h3>Can plants bounce back after excessive fertilizing?</h3>
- A few straightforward procedures can save the majority of over fertilized plants.
- Remove any fertilizer that is readily visible from the soil and plant, and let water pass through the roots to leach the fertilizer away.
- After that, take out any damaged foliage and give your plant another meal after about a month.
